Subject: [PATCH 0001/1026] JFS: commit_mutex cleanups
I look at code, and see that
1)locks wasn't release in the opposite order in which they were taken
2)in jfs_rename we lock new_ip, and in "error path" we didn't unlock it
3)I see strange expression: "! !"
May be this worth to fix?

Subject: [PATCH 0002/1026] e1000: prevent statistics from garbling during bus
resets
If a PCI bus error/fault triggers a PCI bus reset, attempts to get
the ethernet packet count statistics from the hardware will fail,
returning garbage data upstream. This patch skips statistics data
collection if the PCI device is not on the bus.

Ethtool was reporting that loopback failed randomly on esb2
systems. Upon study it was found that the phy manual was changed
with respect to the loopback mode bits. The new value fixes it.

Subject: [PATCH 0004/1026] e1000: rework driver hardware reset locking
After studying the driver mac reset code it was found that there
were multiple race conditions possible to reset the unit twice or
bring it e1000_up() double. This fixes all occurences where the
driver needs to reset the mac.
We also remove irq requesting/releasing into _open and _close so
that while the device is _up we will never touch the irq's. This fixes
the double free irq bug that people saw.
To make sure that the watchdog task doesn't cause another race we let
it run as a non-scheduled task.

Subject: [PATCH 0005/1026] e1000: Make PHY powerup/down a function
In relation to the irq work done earlier we also move the PHY powerup
and powerdown functions into separate functions and move the calls to
_close and _open, making the PHY stay in it's power state as long as
the device is _up.

Subject: [PATCH 0012/1026] e1000: force register write flushes to circumvent
broken platforms
A certain AMD64 bridge (8132) has an option to turn on write combining
which breaks our adapter. To circumvent this we need to flush every write.

This implements the core new functions needed for ich8's internal
NIC. This includes:
* ich8 specific read/write code
* flash/nvm access code
* software semaphore flag functions
* 10/100 PHY (fe - no gigabit speed) support for low-end versions

The workaround for the ich8 lock loss problem is only needed for
a very small amount of systems. This adds an option for the user
to disable the workaround.

This reverts ccf01ef7aa9c6c293a1c64c27331a2ce227916ec commit.
No idea how git managed this one: when I asked it to merge the odirect
topic branch it actually generated a patch which reverted the change.
Reverting the 'merge' will once again reveal Chuck's recent NFS/O_DIRECT
work to the world.

Subject: [PATCH 0024/1026] [ARM] 3710/1: AT91 Serial: Use GPIO API
Patch from Andrew Victor
The AT91RM9200 errata work-around should be using the GPIO API and not
accessing the PIO registers directly.

Subject: [PATCH 0026/1026] [ARM] 3711/1: AT91 timer update
Patch from Andrew Victor
The AIC interrupt controller is the same on the Atmel AT91RM9200,
AT91SAM9261 and AT91SAM9260 processors.
This patch removes any RM9200-specific naming from the IRQ driver, and
moves the AT91RM9200's default IRQ priority table into at91rm9200.c.

locks were actually freed
Change posix_lock_file_conf(), and flock_lock_file() so that if called
with an F_UNLCK argument, and the FL_EXISTS flag they will indicate
whether or not any locks were actually freed by returning 0 or -ENOENT.

The introduction of the FLUSH_INVALIDATE argument to nfs_sync_inode_wait()
does not clear the nr_unstable page state counter for pages that are being
released.
Also fix a longstanding similar bug when nfs_commit_list() fails.

Subject: [PATCH 0036/1026] [netdrvr] Remove Linux-specific changelogs from
several Becker template drivers
When in-kernel net drivers branched from Donald Becker's vanilla driver
set, in the days before BitKeeper and git, a driver changelog was
maintained in the driver source code. These days, the kernel's
changelog is far superior and much more accurate, so the in-driver
changelogs are removed.
Another relic of the Becker/kernel split was version numbering, using
"foo-LKx.y.z" notation, resulting in weird version numbers like
"1.17b-LK1.1.9". These drivers are for older hardware, and see few
changes these days, so the version numbers were all bumped to something
more simple.
Finally, in xircom_tulip_cb specifically, an additional cleanup removes
the always-enabled CARDBUS cpp macro.

- of the 100Mbit autodetection circuitry in rev C cards. (uzi)
-

Subject: [PATCH 0037/1026] [netdrvr] Remove Becker-template 'io_size' member,
when invariant
Becker-derived drivers often have the 'io_size' member in their chip
info struct, indicating the minimum required size of the I/O resource
(usually a PCI BAR). For many situations, this number is either
constant or irrelevant (due to pci_iomap convenience behavior).
This change removes the io_size invariant member, and replaces it with a
compile-time constant.
Drivers updated: fealnx, gt96100eth, winbond-840, yellowfin
Additionally,
- gt96100eth: unused 'drv_flags' removed from gt96100eth
- winbond-840: unused struct match_info removed
- winbond-840: mark pci_id_tbl[] const, __devinitdata

Subject: [PATCH 0040/1026] [netdrvr] via-velocity: misc. cleanups
- const-ify pci_device_id table
- clean up pci_device_id table with PCI_DEVICE()
- don't store internal pointer in pci_device_id table,
use pci_device_id::driver_data as an integer index
- use dev_printk() for messages where eth%d prefix is unavailable
- formatting fixes

For messages prior to register_netdev(), prefer dev_printk() because
that prints out both our driver name and our [PCI | whatever] bus id.

Subject: [PATCH 0044/1026] [PATCH] Add two PLX device IDs
This patch adds device IDs for Symbol LA-4123 and Global Sun Tech
GL24110P to the HostAP PLX driver.
This is not tested with real hardware, but there is no reason why it
shouldn't work.
Please test.

Place the Init-vs-IRQ workaround before any card register
access, because we might not have the wireless core mapped
at all times in init. So this will result in a Machine Check
caused by a bus error.

Currently no problem shows up just because dev_alloc_skb aligns the
data len to SMP_CACHE_BYTES which can be used for ICV.

Subject: [PATCH 0050/1026] [PATCH] 2.6.17 missing a call to
ieee80211softmac_capabilities from ieee80211softmac_assoc_req
In commit ba9b28d19a3251bb1dfe6a6f8cc89b96fb85f683, routine
ieee80211softmac_capabilities was added to ieee80211softmac_io.c. As
denoted by its name, it completes the capabilities IE that is
needed in the associate and reassociate requests sent to the
AP. For at least one AP, the Linksys WRT54G V5, the capabilities
field must set the 'short preamble' bit or the AP refuses to
associate. In the commit noted above, there is a call to the
new routine from ieee80211softmac_reassoc_req, but not from
ieee80211softmac_assoc_req. This patch fixes that oversight.
As noted in the subject, v2.6.17 is affected. My bcm43xx card had been
unable to associate since I was forced to buy a new AP. I finally was
able to get a packet dump and traced the problem to the capabilities
info. Although I had heard that a patch was "floating around", I had
not seen it before 2.6.17 was released. As this bug does not affect
security and I seem to have the only AP affected by it, there should
be no problem in leaving it for 2.6.18.

Subject: [PATCH 0052/1026] [PATCH] SoftMAC: Prevent multiple authentication
attempts on the same network
This patch addresses the "No queue exists" messages commonly seen during
authentication and associating. These appear due to scheduling multiple
authentication attempts on the same network. To prevent this, I added a
flag to stop multiple authentication attempts by the association layer.
I also added a check to the wx handler to see if we're connecting to a
different network than the one already in progress. This scenario was
causing multiple requests on the same network because the network BSSID
was not being updated despite the fact that the ESSID changed.

The ieee80211softmac_call_events function, when called with event type
IEEE80211SOFTMAC_EVENT_ASSOCIATE_TIMEOUT should pass the network as the

WARNING: /lib/modules/2.6.17-mm2/kernel/net/ieee80211/ieee80211.ko
needs unknown symbol wireless_spy_update
Someone removed the `#ifdef CONFIG_WIRELESS_EXT' from around the callsite
in net/ieee80211/ieee80211_rx.c and didn't update Kconfig appropriately.
The offending patchset seems to be 35c14b855f52c49e4f3d078b9532b056005ed321
which is tittled
[PATCH] ieee80211: remove unnecessary CONFIG_WIRELESS_EXT checking
After a quick look it seems that wireless_spy_update() lives in
net/core/wirless.c, and that file is only compiled if
CONFIG_WIRELESS_EXT is set. Perhaps this is Kconig work, but
in the mean time here is a reversal of the recent change.

Subject: [PATCH 0056/1026] [PATCH] ZyDAS ZD1211 USB-WLAN driver
There are 60+ USB wifi adapters available on the market based on the ZyDAS
ZD1211 chip.
Unlike the predecessor (ZD1201), ZD1211 does not have a hardware MAC, so most
data operations are coordinated by the device driver. The ZD1211 chip sits
alongside an RF transceiver which is also controlled by the driver. Our driver
currently supports 2 RF types, we know of one other available in a few marketed
products which we will be supporting soon.
Our driver also supports the newer revision of ZD1211, called ZD1211B. The
initialization and RF operations are slightly different for the new revision,
but the main difference is 802.11e support. Our driver does not support the
QoS features yet, but we think we know how to use them.
This driver is based on ZyDAS's own GPL driver available from www.zydas.com.tw.
ZyDAS engineers have been responsive and supportive of our efforts, so thumbs
up to them. Additionally, the firmware is redistributable and they have
provided device specs.
This driver has been written primarily by Ulrich Kunitz and myself. Graham
Gower, Greg KH, Remco and Bryan Rittmeyer have also contributed. The
developers of ieee80211 and softmac have made our lives so much easier- thanks!
We maintain a small info-page: http://zd1211.ath.cx/wiki/DriverRewrite
If there is enough time for review, we would like to aim for inclusion in
2.6.18. The driver works nicely as a STA, and can connect to both open and
encrypted networks (we are using software-based encryption for now). We will
work towards supporting more advanced features in the future (ad-hoc, master
mode, 802.11a, ...).

Subject: [PATCH 0064/1026] [PATCH] pcnet32: Suspend the chip rather than
restart when changing multicast/promisc
Suspend the chip if possible rather than stop and discard all tx and rx
frames, when changing the mcast list or entering/leaving promiscuous
mode. Created common pcnet32_suspend routine.
Tested ia32 and ppc64

Subject: [PATCH 0066/1026] [PATCH] lock validator: fix ns83820.c irq-flags bug

this is caused because the ns83820 driver re-enables irq flags
in hardirq context.
While legal in theory, in practice it should only be done if the
hardware is really old and has some very high overhead in its ISR.
(such as PIO IDE)
For modern hardware, running ISRs with irqs enabled is discouraged,
because 1) new hardware is fast enough to not cause latency problems
2) allowing the nesting of hardware interrupts only 'spreads out'
the handling of the current ISR, causing extra cachemisses that would
otherwise not happen. Furthermore, on architectures where ISRs share
the kernel stacks, enabling interrupts in ISRs introduces a much
higher kernel-stack-nesting and thus kernel-stack-overflow risk.
3) not managing irq-flags via the _irqsave / _irqrestore variants
is dangerous: it's easy to forget whether one function nests inside
another, and irq flags might be mismanaged.
In the few cases where re-enabling interrupts in an ISR is considered
useful (and unavoidable), it has to be taught to the lock validator
explicitly (because the lock validator needs the "no ISR ever enables
hardirqs" artificial simplification to keep the IRQ/softirq locking
dependencies manageable).
This teaching is done via the explicit use local_irq_enable_in_hardirq().
On a stock kernel this maps to local_irq_enable(). If the lock validator
is enabled then this does not enable interrupts.
Now, the analysis of drivers/net/ns83820.c's irq flags use: the
irq-enabling in irq context seems intentional, but i dont think it's
justified. Furthermore, the driver suffers from problem #3 above too,
in ns83820_tx_timeout() it disables irqs via local_irq_save(), but
then it calls do_tx_done() which does a spin_unlock_irq(),
re-enabling for a function that does not expect it! While currently
this bug seems harmless (only some debug printout seems to be
affected by it), it's nevertheless something to be fixed.
So this patch makes the ns83820 ISR irq-flags-safe, and cleans up
do_tx_done() use and locking to avoid the ns83820_tx_timeout() bug.
From: Arjan van de Ven <arjan@linux.intel.com>
ns83820_mib_isr takes the misc_lock in IRQ context. All other places that
do this in the ISR already use _irqsave versions, make this consistent at
least. At some point in the future someone should audit the driver to see
if all _irqsave's in the ISR can go away, this is generally an iffy/fragile
proposition though; for now get it safe, simple and consistent.
From: Arjan van de Ven <arjan@linux.intel.com>
ok this is a real driver deadlock:
The ns83820 driver enabled interrupts (by unlocking the misc_lock with
_irq) while still holding the rx_info.lock, which is required to be irq
safe since it's used in the ISR like this:
writel(1, dev->base + IER);
spin_unlock_irq(&dev->misc_lock);
kick_rx(ndev);
spin_unlock_irq(&dev->rx_info.lock);
This is can cause a deadlock if an irq was pending at the first
spin_unlock_irq already, or if one would hit during kick_rx().
Simply remove the first _irq solves this

Subject: [PATCH 0075/1026] [PATCH] 8139too deadlock fix
> stack backtrace:
> [<f9099d31>] rtl8139_start_xmit+0xd9/0xff [8139too]
> [<c11ad5ea>] netpoll_send_skb+0x98/0xea
This seems to be a real deadlock...
So netpoll_send_skb takes the _xmit_lock, which is all nitty gritty
but then rtl8139_start_xmit comes around while that lock is taken, and
does
spin_unlock_irq(&tp->lock);
which.. enables interrupts and softirqs; this is quite bad because the
xmit lock is taken in softirq context for the watchdog like this:
[<c1200376>] _spin_lock+0x23/0x32
[<c11af282>] dev_watchdog+0x14/0xb1
[<c101dab2>] run_timer_softirq+0xf2/0x14a
[<c101a691>] __do_softirq+0x55/0xb0
[<c1004a8d>] do_softirq+0x58/0xbd
Which would deadlock now that the spin_unlock_irq() has enabled
irqs/softirqs while the _xmit_lock is still held.
The patch below turns this into a irqsave/irqrestore pair so that
interrupts don't get enabled unconditionally.

Subject: [PATCH 0078/1026] [PATCH] libata: add ap->pflags and move core
dynamic flags to it
ap->flags is way too clamped. Separate out core dynamic flags to
ap->pflags. ATA_FLAG_DISABLED is a dynamic flag but left alone as
it's referenced by a lot of LLDs and it's gonna be removed once all
LLDs are converted to new EH.

ata_eh_autopsy() used to directly assign determined action mask to
ehc->i.action thus overriding actions set by some of nested analyze
functions. This patch makes ata_eh_autopsy() add action masks just as
it's done in other places.

Subject: [PATCH 0080/1026] [PATCH] libata: replace ap_lock w/ ap->lock in
ata_scsi_error()
ap_lock was used because &ap->host_set->lock was too long and used a
lot. Now that &ap->host_set->lock is replaced with ap->lock, there's
no reason to keep ap_lock.
[ed. note: that's not entirely true. ap_lock is a local variable,
caching the results of a de-ref. In theory, if the compiler is smart
enough, this patch is cosmetic. However, since this is not a fast
path (it is the error path), this patch is nonetheless acceptable,
even though it _may_ introduce a performance regression.]

Subject: [PATCH 0081/1026] [PATCH] libata: implement ATA_EHI_RESUME_LINK
Implement ATA_EHI_RESUME_LINK, which indicates that the link needs to
be resumed. This used to be implied by ATA_EHI_HOTPLUGGED. However,
hotplug isn't the only event which requires link resume and separating
this out allows other places to request link resume. This
differentiation also allows better debounce timing selection.
This patch converts user scan to use ATA_EHI_RESUME_LINK.

Subject: [PATCH 0082/1026] [PATCH] libata: clean up debounce parameters and
improve parameter selection
The names of predefined debounce timing parameters didn't exactly
match their usages. Rename to more generic names and implement param
selection helper sata_ehc_deb_timing() which uses EHI_HOTPLUGGED to
select params.
Combined with the previous EHI_RESUME_LINK differentiation, this makes
parameter selection accurate. e.g. user scan resumes link but normal
deb param is used instead of hotplug param.

Implement ATA_EHI_NO_AUTOPSY and QUIET. These used to be implied by
ATA_PFLAG_LOADING, but new power management and PMP support need to
use these separately. e.g. Suspend/resume operations shouldn't print
full EH messages and resume shouldn't be recorded as an error.

Subject: [PATCH 0085/1026] [PATCH] libata: implement PM EH actions
Implement two PM per-dev EH actions - ATA_EH_SUSPEND and
ATA_EH_RESUME. Each action puts the target device into suspended mode
and resumes from it respectively.
Once a device is put to suspended mode, no EH operations other than
RESUME is allowed on the device. The device will stay suspended till
it gets resumed and thus reset and revalidated. To implement this, a
new device state helper - ata_dev_ready() - is implemented and used in
EH action implementations to make them operate only on attached &
running devices.
If all possible devices on a port are suspended, reset is skipped too.
This prevents spurious events including hotplug events from disrupting
suspended devices.

Subject: [PATCH 0086/1026] [PATCH] libata: reimplement per-dev PM
Reimplement per-dev PM. The original implementation directly put the
device into suspended mode and didn't synchronize w/ EH operations
including hotplug. This patch reimplements ata_scsi_device_suspend()
and ata_scsi_device_resume() such that they request EH to perform the
respective operations. Both functions synchronize with hotplug such
that it doesn't operate on detached devices.
Suspend waits for completion but resume just issues request and
returns. This allows parallel wake up of devices and thus speeds up
system resume.
Due to sdev detach synchronization, it's not feasible to separate out
EH requesting from sdev handling; thus, ata_device_suspend/resume()
are removed and everything is implemented in the respective
libata-scsi functions.

Subject: [PATCH 0087/1026] [PATCH] libata: reimplement controller-wide PM
Reimplement controller-wide PM. ata_host_set_suspend/resume() are
defined to suspend and resume a host_set. While suspended, EHs for
all ports in the host_set are pegged using ATA_FLAG_SUSPENDED and
frozen.
Because SCSI device hotplug is done asynchronously against the rest of
libata EH and the same mutex is used when adding new device, suspend
cannot wait for hotplug to complete. So, if SCSI device hotplug is in
progress, suspend fails with -EBUSY.
In most cases, host_set resume is followed by device resume. As each
resume operation requires a reset, a single host_set-wide resume
operation may result in multiple resets. To avoid this, resume waits
upto 1 second giving PM to request resume for devices.

The sparc64 kernel's EXPORT_SYMBOL(_mcount) is inside an
#ifdef CONFIG_SMP. This breaks modules in non-SMP kernels
built with stack overflow checking (CONFIG_STACK_DEBUG=y),
as modules_install reports:
WARNING: /lib/modules/2.6.17/kernel/drivers/ide/ide-cd.ko needs unknown symbol _mcount
Trivially fixed by moving EXPORT_SYMBOL(_mcount) outside of
the #ifdef CONFIG_SMP.

Subject: [PATCH 0097/1026] [PKT_SCHED]: Fix illegal memory dereferences when
dumping actions
The TCA_ACT_KIND attribute is used without checking its
availability when dumping actions therefore leading to a
value of 0x4 being dereferenced.
The use of strcmp() in tc_lookup_action_n() isn't safe
when fed with string from an attribute without enforcing
proper NUL termination.
Both bugs can be triggered with malformed netlink message
and don't require any privileges.

make sure the cpu hotplug recursive mutex (yuck) is taken early in the
cpufreq codepaths to avoid a AB-BA deadlock.

ok this is a real potential deadlock in a way, it takes two locks of 2
skbuffs without doing any kind of lock ordering; I think the following
patch should fix it. Just sort the lock taking order by address of the
skb.. it's not pretty but it's the best this can do in a minimally

Subject: [PATCH 0112/1026] [NET] gso: Fix up GSO packets with broken checksums
Certain subsystems in the stack (e.g., netfilter) can break the partial
checksum on GSO packets. Until they're fixed, this patch allows this to
work by recomputing the partial checksums through the GSO mechanism.
Once they've all been converted to update the partial checksum instead of
clearing it, this workaround can be removed.

Subject: [PATCH 0115/1026] i386: improve and correct inline asm memory
constraints
Use "+m" rather than a combination of "=m" and "m" for improved clarity
and consistency.
This also fixes some inlines that incorrectly didn't tell the compiler
that they read the old value at all, potentially causing the compiler to
generate bogus code. It appear that all of those potential bugs were
hidden by the use of extra "volatile" specifiers on the data structures
in question, though.

Subject: [PATCH 0117/1026] [SCSI] scsi_transport_sas: add unindexed ports
Some SAS HBAs don't want to go to the trouble of tracking port numbers,
so they'd simply like to say "add this port and give it a number".
This is especially beneficial from the hotplug point of view, since
tracking ports and the available number space can be a real pain.
The current implementation uses an incrementing number per expander to
add the port on. However, since there can never be more ports than
there are phys, a later implementation will try to be more intelligent
about this.

Subject: [PATCH 0119/1026] [SCSI] mptsas: use unnumbered port API and remove
driver porttracking
This allows us to be rid of the machinery in mptsas for creating and
tracking port numbers. Since mptsas is merely inventing the numbers,
the SAS transport class may as well do it instead.

This reverts commit a5e1b94008f2a96abf4a0c0371a55a56b320c13e.
Adrian Bunk points out that it has build errors, and apparently no
maintenance. Throw it out.

- Fix some sparse warnings - casts of address space
- Fix handling of the adapter registration string. Each invocation

Subject: [PATCH 0137/1026] [SCSI] aha152x: stop poking at saved scsi_cmnd
members
Stop poking into the old_ & co scsi_cmnd fields that should only be used
in the EH code. Untested, but this is required to move ahead with the
EH fixes.

Subject: [PATCH 0141/1026] [SCSI] hide EH backup data outside the scsi_cmnd
Currently struct scsi_cmnd has various fields that are used to backup
original data after the corresponding fields have been overridden for
EH commands. This means drivers can easily get at it and misuse it.
Due to the old_ naming this doesn't happen for most of them, but two
that have different names have been used wrong a lot (see previous
patch). Another downside is that they unessecarily bloat the scsi_cmnd
size.
This patch moves them onstack in scsi_send_eh_cmnd to fix those two
issues aswell as allowing future EH fixes like moving the EH command
submissions to use SG lists like everything else.

Subject: [PATCH 0145/1026] ACPI: ACPICA 20060707
Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to
support C compilers that do not allow the initialization
of address pointers within packed structures - even though
the hardware itself may support misaligned transfers. Some
of the debug data structures are packed by default to
minimize size.
Added an error message for the case where
acpi_os_get_thread_id() returns zero. A non-zero value is
required by the core ACPICA code to ensure the proper
operation of AML mutexes and recursive control methods.
The DSDT is now the only ACPI table that determines whether
the AML interpreter is in 32-bit or 64-bit mode. Not really
a functional change, but the hooks for per-table 32/64
switching have been removed from the code. A clarification
to the ACPI specification is forthcoming in ACPI 3.0B.
Fixed a possible leak of an Owner ID in the error
path of tbinstal.c acpi_tb_init_table_descriptor() and
migrated all table OwnerID deletion to a single place in
acpi_tb_uninstall_table() to correct possible leaks when using
the acpi_tb_delete_tables_by_type() interface (with assistance
from Lance Ortiz.)
Fixed a problem with Serialized control methods where the
semaphore associated with the method could be over-signaled
after multiple method invocations.
Fixed two issues with the locking of the internal
namespace data structure. Both the Unload() operator and
acpi_unload_table() interface now lock the namespace during
the namespace deletion associated with the table unload
(with assistance from Linn Crosetto.)
Fixed problem reports (Valery Podrezov) integrated: -
Eliminate unnecessary memory allocation for CreateXxxxField
http://bugzilla.kernel.org/show_bug.cgi?id=5426
Fixed problem reports (Fiodor Suietov) integrated: -
Incomplete cleanup branches in AcpiTbGetTableRsdt (BZ 369)
- On Address Space handler deletion, needless deactivation
call (BZ 374) - AcpiRemoveAddressSpaceHandler: validate
Device handle parameter (BZ 375) - Possible memory leak,
Notify sub-objects of Processor, Power, ThermalZone (BZ
376) - AcpiRemoveAddressSpaceHandler: validate Handler
parameter (BZ 378) - Minimum Length of RSDT should be
validated (BZ 379) - AcpiRemoveNotifyHandler: return
AE_NOT_EXIST if Processor Obj has no Handler (BZ (380)
- AcpiUnloadTable: return AE_NOT_EXIST if no table of
specified type loaded (BZ 381)

Subject: [PATCH 0146/1026] ACPI: acpi_os_get_thread_id() returns current
Linux mutexes and the debug code that that reference
acpi_os_get_thread_id() are happy with 0.
But the AML mutexes in exmutex.c expect a unique non-zero
number for each thread - as they track this thread_id
to permit the mutex re-entrancy defined by the ACPI spec.

Subject: [PATCH 0148/1026] [SERIAL] IP22: fix serial console hangs
The patch below fixes serial console hangs as seen on IP22
machines. Typically, while booting, the machine hangs for ~1 minute
displaying "INIT: ", then the same thing happens again when init
enters in the designated runlevel and finally the getty process on
ttyS0 hangs indefinitely (though strace'ing it helps).
strace (-e raw=ioctl, otherwise the ioctl() translation is utterly
bogus) reveals that getty hangs on ioctl() 0x540f which happens to be
TCSETSW (I saw it hang on another console ioctl() but couldn't
reproduce that one).
A diff between ip22zilog and sunzilog revealed the following
differences:
1. the channel A flag being set on up.port.flags instead of up.flags
2. the channel A flag being set on what is marked as being channel B
3. sunzilog has a call to uart_update_timeout(port, termios->c_cflag, baud);
at the end of sunzilog_set_termios(), which ip22zilog lacks (on
purpose ?)
The patch below addresses point 1 and fixes the serial console hangs
just fine. However point 2 should be investigated by someone familiar
with the IP22 Zilog; it's probably OK as is but even if it is, a
comment in ip22zilog.c is badly needed.
Point 3 is left as an exercise for whoever feels like digging into
ip22zilog :)
These are the main obvious differences between ip22zilog and
sunzilog. Newer versions of sunzilog (Linus's git tree as of today)
are more close to ip22zilog as the sbus_{write,read}b have been
changed into simple {write,read}b, which shrinks the diff by a fair
amount. Resyncing both drivers should be doable in a few hours time
now for someone familiar with the IP22 Zilog hardware.

Subject: [PATCH 0149/1026] [SERIAL] 8250: add tsi108 serial support
The following patch gets rid of CONFIG_TSI108_BRIDGE. I add UPIO_TSI to
handle IIR and IER register in serial_in and serial_out.
(1) the reason to rewrite serial_in:
TSI108 rev Z1 version ERRATA. Reading the UART's Interrupt
Identification Register (IIR) clears the Transmit Holding Register
Empty (THRE) and Transmit buffer Empty (TEMP) interrupts even if they
are not enabled in the Interrupt Enable Register (IER). This leads to
loss of the interrupts. Interrupts are not cleared when reading UART
registers as 32-bit word.
(2) the reason to rewrite serial_out:
Check for UART_IER_UUE bit in the autoconfig routine. This section
of autoconfig is excluded for Tsi108/109 because bits 7 and 6 are
reserved for internal use. They are R/W bits. In addition to
incorrect identification, changing these bits (from 00) will make
Tsi108/109 UART non-functional.

Subject: [PATCH 0152/1026] [PATCH] i386: use thread_info flags for debug regs
and IO bitmaps
Use thread info flags to track use of debug registers and IO bitmaps.
- add TIF_DEBUG to track when debug registers are active
- add TIF_IO_BITMAP to track when I/O bitmap is used
- modify __switch_to() to use the new TIF flags
Performance tested on Pentium II, ten runs of LMbench context switch
benchmark (smaller is better:)

Subject: [PATCH 0157/1026] ACPI: SBS: fix initialization, sem2mutex
cm_sbs_sem is being downed (via acpi_ac_init->acpi_lock_ac_dir) before it is
initialised, with grave results.
- Make it a mutex
- Initialise it
- Make it static
- Clean other stuff up.

Subject: [PATCH 0158/1026] ACPI: acpi_os_allocate() fixes
Replace acpi_in_resume with a more general hack
to check irqs_disabled() on any kmalloc() from ACPI.
While setting (system_state != SYSTEM_RUNNING) on resume
seemed more general, Andrew Morton preferred this approach.
http://bugzilla.kernel.org/show_bug.cgi?id=3469
Make acpi_os_allocate() into an inline function to
allow /proc/slab_allocators to work.
Delete some memset() that could fault on allocation failure.

Subject: [PATCH 0159/1026] [PATCH] splice: fix problems with sys_tee()
Several issues noticed/fixed:
- We cannot reliably block in link_pipe() while holding both input and output
mutexes. So do preparatory checks before locking down both mutexes and doing
the link.
- The ipipe->nrbufs vs i check was bad, because we could have dropped the
ipipe lock in-between. This causes us to potentially look at unknown
buffers if we were racing with someone else reading this pipe.

It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing
and for section-checking coverage. But a few things go and select
CONFIG_HOTPLUG, making it a royal PITA to turn the thing off.
It's only turnable offable if CONFIG_EMBEDDED anyway. So let's make those
things depend on HOTPLUG, not select it.

Subject: [PATCH 0166/1026] [PATCH] sched: fix bug in __migrate_task()
Problem:
In the function __migrate_task(), deactivate_task() followed by
activate_task() is used to move the task from one run queue to
another. This has two undesirable effects:
1. The task's priority is recalculated. (Nowhere else in the
scheduler code is the priority recalculated for a change of CPU.)
2. The task's time stamp is set to the current time. At the very least,
this makes the adjustment of the time stamp before the call to
deactivate_task() redundant but I believe the problem is more serious
as the time stamp now holds the time of the queue change instead of
the time at which the task was woken. In addition, unless dest_rq is
the same queue as "current" is on the time stamp could be inaccurate
due to inter CPU drift.
Solution:
Replace the call to activate_task() with one to __activate_task().

root inode when mounting
Introduce a new rootcontext= option to FS mounting. This option will allow
you to explicitly label the root inode of an FS being mounted before that
FS or inode because visible to userspace. This was found to be useful for
things like stateless linux, see

Subject: [PATCH 0170/1026] [PATCH] reiserfs: fix journaling issue regarding
fsync()
When write() extends a file(i_size is increased) and fsync() is called,
change of inode must be written to journaling area through fsync().
But,currently the i_trans_id is not correctly updated when i_size is
increased. So fsync() does not kick the journal writer.
Reiserfs_file_write() already updates the transaction when blocks are
allocated, but the case when i_size increases and new blocks are not added
is not correctly treated.
Following patch fix this bug.

+ ----------
+
+To get the kernel into memory different approaches can be used.
+They depend on various facilities being available:
-3.1) Writing the kernel onto a floppy using dd:
- As always you can just write the kernel onto a floppy using dd,
- but then it's not possible to use kernel command lines at all.
- To substitute the 'root=' parameter, create a dummy device on any
- linux system with major number 0 and minor number 255 using mknod:
+3.1) Booting from a floppy using syslinux
- mknod /dev/boot255 c 0 255
+ When building kernels, an easy way to create a boot floppy that uses
+ syslinux is to use the zdisk or bzdisk make targets which use
+ and bzimage images respectively. Both targets accept the
+ FDARGS parameter which can be used to set the kernel command line.
- Then copy the kernel zImage file onto a floppy using dd:
+ e.g.
+ make bzdisk FDARGS="root=/dev/nfs"
- dd if=/usr/src/linux/arch/i386/boot/zImage of=/dev/fd0
+ Note that the user running this command will need to have
+ access to the floppy drive device, /dev/fd0
- And finally use rdev to set the root device:
+ For more information on syslinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/
- rdev /dev/fd0 /dev/boot255
+ N.B: Previously it was possible to write a kernel directly to
+ a floppy using dd, configure the boot device using rdev, and
+ boot using the resulting floppy. Linux no longer supports this
+ method of booting.
- You can then remove the dummy device /dev/boot255 again. There
- is no real device available for it.
- The other two kernel command line parameters cannot be substi-
- tuted with rdev. Therefore, using this method the kernel will
- by default use RARP and/or BOOTP, and if it gets an answer via
- RARP will mount the directory /tftpboot/<client-ip>/ as its
- root. If it got a BOOTP answer the directory name in that answer
- is used.
+3.2) Booting from a cdrom using isolinux
+
+ When building kernels, an easy way to create a bootable cdrom that
+ uses isolinux is to use the isoimage target which uses a bzimage
+ image. Like zdisk and bzdisk, this target accepts the FDARGS
+ parameter which can be used to set the kernel command line.
+
+ e.g.
+ make isoimage FDARGS="root=/dev/nfs"
+
+ The resulting iso image will be arch/<ARCH>/boot/image.iso
+ This can be written to a cdrom using a variety of tools including
+ cdrecord.
+
+ e.g.
+ cdrecord dev=ATAPI:1,0,0 arch/i386/boot/image.iso
+
+ For more information on isolinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/
3.2) Using LILO
- When using LILO you can specify all necessary command line
- parameters with the 'append=' command in the LILO configuration
- file. However, to use the 'root=' command you also need to
- set up a dummy device as described in 3.1 above. For how to use
- LILO and its 'append=' command please refer to the LILO
- documentation.
+ When using LILO all the necessary command line parameters may be
+ specified using the 'append=' directive in the LILO configuration
+ file.
+
+ However, to use the 'root=' directive you also need to create
+ a dummy root device, which may be removed after LILO is run.
+
+ mknod /dev/boot255 c 0 255
+
+ For information on configuring LILO, please refer to its documentation.
3.3) Using GRUB
- When you use GRUB, you simply append the parameters after the kernel
- specification: "kernel <kernel> <parameters>" (without the quotes).
+ When using GRUB, kernel parameter are simply appended after the kernel
+ specification: kernel <kernel> <parameters>
3.4) Using loadlin
- When you want to boot Linux from a DOS command prompt without
- having a local hard disk to mount as root, you can use loadlin.
- I was told that it works, but haven't used it myself yet. In
- general you should be able to create a kernel command line simi-
- lar to how LILO is doing it. Please refer to the loadlin docu-
- mentation for further information.
+ loadlin may be used to boot Linux from a DOS command prompt without
+ requiring a local hard disk to mount as root. This has not been
+ thoroughly tested by the authors of this document, but in general
+ it should be possible configure the kernel command line similarly
+ to the configuration of LILO.
+
+ Please refer to the loadlin documentation for further information.
3.5) Using a boot ROM
- This is probably the most elegant way of booting a diskless
- client. With a boot ROM the kernel gets loaded using the TFTP
- protocol. As far as I know, no commercial boot ROMs yet
- support booting Linux over the network, but there are two
- free implementations of a boot ROM available on sunsite.unc.edu
- and its mirrors. They are called 'netboot-nfs' and 'etherboot'.
- Both contain everything you need to boot a diskless Linux client.
+ This is probably the most elegant way of booting a diskless client.
+ With a boot ROM the kernel is loaded using the TFTP protocol. The
+ authors of this document are not aware of any no commercial boot
+ ROMs that support booting Linux over the network. However, there
+ are two free implementations of a boot ROM, netboot-nfs and
+ etherboot, both of which are available on sunsite.unc.edu, and both
+ of which contain everything you need to boot a diskless Linux client.
3.6) Using pxelinux
- Using pxelinux you specify the kernel you built with
+ Pxelinux may be used to boot linux using the PXE boot loader
+ which is present on many modern network cards.
+
+ When using pxelinux, the kernel image is specified using
"kernel <relative-path-below /tftpboot>". The nfsroot parameters
are passed to the kernel by adding them to the "append" line.
- You may perhaps also want to fine tune the console output,
- see Documentation/serial-console.txt for serial console help.
+ It is common to use serial console in conjunction with pxeliunx,
+ see Documentation/serial-console.txt for more information.
+
+ For more information on isolinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/

Subject: [PATCH 0174/1026] [PATCH] partitions: let partitions inherit policy
from disk
Change the partition code in fs/partitions/check.c to initialize a newly
detected partition's policy field with that of the containing block device
(see patch below).
My reasoning is that function set_disk_ro() in block/genhd.c modifies the
policy field (read-only indicator) of a disk and all contained partitions.
When a partition is detected after the call to set_disk_ro(), the policy
field of this partition will currently not inherit the disk's policy field.
This behavior poses a problem in cases where a block device can be
'logically de- and reactivated' like e.g. the s390 DASD driver because
partition detection may run after the policy field has been modified.

Subject: [PATCH 0179/1026] [PATCH] lockdep: core, reduce per-lock class-cache
size
lockdep_map is embedded into every lock, which blows up data structure
sizes all around the kernel. Reduce the class-cache to be for the default
class only - that is used in 99.9% of the cases and even if we dont have a
class cached, the lookup in the class-hash is lockless.
This change reduces the per-lock dep_map overhead by 56 bytes on 64-bit
platforms and by 28 bytes on 32-bit platforms.

Subject: [PATCH 0185/1026] [PATCH] release_firmware() fixes
Use release_firmware() to free requested resources.
According to Documentation/firmware_class/README the request_firmware()
call should be followed by a release_firmware(). Some drivers do not
however free the firmware previously allocated with request_firmware().
This patch tries to fix this by making sure that release_firmware() is used
as expected.

From a8f340e394ff30b79ab5b03c67ab4c94b2ac3646 Mon Sep 17 00:00:00 2001
From: Jon Smirl <jonsmir@gmail.com>
Date: Mon, 10 Jul 2006 04:44:12 -0700
Subject: [PATCH 0188/1026] [PATCH] vt: Remove VT-specific declarations and
definitions from tty.h
MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h
allows all of the framebuffer and VT console drivers to remove their
dependency on tty.h.

From 894673ee6122a3ce1958e1fe096901ba5356a96b Mon Sep 17 00:00:00 2001
From: Jon Smirl <jonsmir@gmail.com>
Date: Mon, 10 Jul 2006 04:44:13 -0700
Subject: [PATCH 0189/1026] [PATCH] tty: Remove include of screen_info.h from
tty.h
screen_info.h doesn't have anything to do with the tty layer and shouldn't be
included by tty.h. This patches removes the include and modifies all users to
directly include screen_info.h. struct screen_info is mainly used to
communicate with the console drivers in drivers/video/console. Note that this
patch touches every arch and I have no way of testing it. If there is a
mistake the worst thing that will happen is a compile error.

Subject: [PATCH 0190/1026] [PATCH] md: possible fix for unplug problem
I have reports of a problem with raid5 which turns out to be because the raid5
device gets stuck in a 'plugged' state. This shouldn't be able to happen as
3msec after it gets plugged it should get unplugged. However it happens
none-the-less. This patch fixes the problem and is a reasonable thing to do,
though it might hurt performance slightly in some cases.
Until I can find the real problem, we should probably have this workaround in
place.

Subject: [PATCH 0192/1026] [PATCH] md: delay starting md threads until array
is completely setup
When an array is started we start one or two threads (two if there is a
reshape or recovery that needs to be completed).
We currently start these *before* the array is completely set up and in
particular before queue->queuedata is set. If the thread actually starts
very quickly on another CPU, we can end up dereferencing queue->queuedata
and oops.
This patch also makes sure we don't try to start a recovery if a reshape is
being restarted.

Subject: [PATCH 0193/1026] [PATCH] md: fix resync speed calculation for
restarted resyncs
We introduced 'io_sectors' recently so we could count the sectors that causes
io during resync separate from sectors which didn't cause IO - there can be a
difference if a bitmap is being used to accelerate resync.
However when a speed is reported, we find the number of sectors processed
recently by subtracting an oldish io_sectors count from a current
'curr_resync' count. This is wrong because curr_resync counts all sectors,
not just io sectors.
So, add a field to mddev to store the curren io_sectors separately from
curr_resync, and use that in the calculations.

Subject: [PATCH 0194/1026] [PATCH] md: fix a plug/unplug race in raid5
When a device is unplugged, requests are moved from one or two (depending on
whether a bitmap is in use) queues to the main request queue.
So whenever requests are put on either of those queues, we should make sure
the raid5 array is 'plugged'. However we don't. We currently plug the raid5
queue just before putting requests on queues, so there is room for a race. If
something unplugs the queue at just the wrong time, requests will be left on
the queue and nothing will want to unplug them. Normally something else will
plug and unplug the queue fairly soon, but there is a risk that nothing will.

Subject: [PATCH 0196/1026] [PATCH] md: fix usage of wrong variable in raid1
Though it rarely matters, we should be using 's' rather than r1_bio->sector
here.

Subject: [PATCH 0197/1026] [PATCH] md: unify usage of symbolic names for perms
Some places we use number (0660) someplaces names (S_IRUGO). Change all
numbers to be names, and change 0655 to be what it should be.
Also make some formatting more consistent.

Subject: [PATCH 0198/1026] [PATCH] md: require CAP_SYS_ADMIN for
(re-)configuring md devices via sysfs
The ioctl requires CAP_SYS_ADMIN, so sysfs should too. Note that we don't
require CAP_SYS_ADMIN for reading attributes even though the ioctl does.
There is no reason to limit the read access, and much of the information is
already available via /proc/mdstat

Subject: [PATCH 0208/1026] [PATCH] ACPI: fix fan/thermal resume
Daniel Ritz <daniel.ritz-ml@swissonline.ch> says:
The acpi driver suspend/resume patches that went in recently caused a regression
on my box (toshiba tecra 8000 laptop): after resume from swsusp the fan turns on
keeping blowing cold air out of my notebook. before the patches, the fan was off
and would only make noise when required. it's the same thing described in
bugzilla.kernel.org #5000. the acpi suspend/resume patches or at least parts of
them originate in this bug. now the last patch in the report (attach id 8438)
actually fixes the problem - for me and the reporter. this is a trimmed down
version of that patch.

configuration
It turns out that there is a way to build a kernel with NUMA and no SMP.
In that case we are missing one definition __inc_zone_state.
Provide that missing __inc_zone_state.
(akpm: NUMA && !SMP sounds odd, but I am told "But there is the concept of
cpuless nodes. A NUMA system without SMP has a single processor but multiple
memory nodes. This used to work before on IA64 (wasn't aware of it, never seen
anyone with this kind of thing).")

A large number of lost ticks can cause an overadjustment of the clock. To

already is the more careful we are at adjusting the error. As small extra
fix reset the error when the clock is set.

Subject: [PATCH 0215/1026] [PATCH] aoa: i2sbus: fix for PowerMac7,2 and 7,3
This patch cleans up the resource handling in i2sbus and adds workarounds for
the broken device trees on the PowerMac7,2 and 7,3. Some of this code will
later move again when macio_asic is going to export all the sub-nodes too.

Subject: [PATCH 0216/1026] [PATCH] aoa: fix when all is built into the kernel
This patch fixes initialisation issues when all of aoa is built into the
kernel by re-ordering the link order in the Makefile and making the soundbus
use subsys_initcall so it is initialised earlier.

Subject: [PATCH 0221/1026] [PATCH] aoa: tas: fix initialisation/reset
This patch fixes the initialisation and reset of the tas codec. The tas will
often reset if the i2s clocks go away so it needs to be completely
re-initialised when clocks come back.
Also, this patch adds some code for DRC that will be exploited later to add a
DRC control again, fixing a regression over snd-powermac.

Subject: [PATCH 0225/1026] [PATCH] powerpc: fix trigger handling in the new
irq code
This patch slightly reworks the new irq code to fix a small design error. I
removed the passing of the trigger to the map() calls entirely, it was not a
good idea to have one call do two different things. It also fixes a couple of
corner cases.
Mapping a linux virtual irq to a physical irq now does only that. Setting the
trigger is a different action which has a different call.
The main changes are:
- I no longer call host->ops->map() for an already mapped irq, I just return
the virtual number that was already mapped. It was called before to give an
opportunity to change the trigger, but that was causing issues as that could
happen while the interrupt was in use by a device, and because of the
trigger change, map would potentially muck around with things in a racy way.
That was causing much burden on a given's controller implementation of
map() to get it right. This is much simpler now. map() is only called on
the initial mapping of an irq, meaning that you know that this irq is _not_
being used. You can initialize the hardware if you want (though you don't
have to).
- Controllers that can handle different type of triggers (level/edge/etc...)
now implement the standard irq_chip->set_type() call as defined by the
generic code. That means that you can use the standard set_irq_type() to
configure an irq line manually if you wish or (though I don't like that
interface), pass explicit trigger flags to request_irq() as defined by the
generic kernel interfaces. Also, using those interfaces guarantees that
your controller set_type callback is called with the descriptor lock held,
thus providing locking against activity on the same interrupt (including
mask/unmask/etc...) automatically. A result is that, for example, MPIC's
own map() implementation calls irq_set_type(NONE) to configure the hardware
to the default triggers.
- To allow the above, the irq_map array entry for the new mapped interrupt
is now set before map() callback is called for the controller.
- The irq_create_of_mapping() (also used by irq_of_parse_and_map()) function
for mapping interrupts from the device-tree now also call the separate
set_irq_type(), and only does so if there is a change in the trigger type.
- While I was at it, I changed pci_read_irq_line() (which is the helper I
would expect most archs to use in their pcibios_fixup() to get the PCI
interrupt routing from the device tree) to also handle a fallback when the
DT mapping fails consisting of reading the PCI_INTERRUPT_PIN to know wether
the device has an interrupt at all, and the the PCI_INTERRUPT_LINE to get an
interrupt number from the device. That number is then mapped using the
default controller, and the trigger is set to level low. That default
behaviour works for several platforms that don't have a proper interrupt
tree like Pegasos. If it doesn't work for your platform, then either
provide a proper interrupt tree from the firmware so that fallback isn't
needed, or don't call pci_read_irq_line()
- Add back a bit that got dropped by my main rework patch for properly
clearing pending IPIs on pSeries when using a kexec

Subject: [PATCH 0227/1026] [PATCH] powerpc: fix SMU driver interrupt mapping
The SMU driver tries to map an interrupt from the device-tree before the
interrupt controllers in the machine have been enumerated. This doesn't work
properly and cause machines like the Quad g5 to fail booting later on when
some drivers waits endlessly for an SMU request to complete. This is the
second problem preventing boot on the Quad g5. This fixes it and also makes
the SMU driver a bit more resilient to not having an interrupt.

This patch fixes a bit of boundchecking in the new Open Firmware interrupt
tree parsing code. It's important that it fails when things aren't correct in
order to trigger fallback mecanisms that are necessary to make some machines
work properly.

Subject: [PATCH 0229/1026] [PATCH] powermac: Combined fixes for backlight code
This patch fixes several problems:
- pmac_backlight_key() is called under interrupt context, and therefore
can't use mutexes or semaphores, so defer the backlight level for
later, as it's not critical (original code by Aristeu S. Rozanski F.
<aris@valeta.org>).
- Add exports for functions that might be called from modules
- Fix Kconfig depdencies on PMAC_BACKLIGHT.
- Fix locking issues on calls from inside the driver (reported by
Aristeu S. Rozanski F., too)
- Fix wrong calculation of backlight values in some of the drivers
- Replace pmac_backlight_key_up/down by inline functions
[akpm@osdl.org: fix function prototypes]

Subject: [PATCH 0230/1026] [PATCH] pci: initialize struct pci_dev.error_state
The pci channel state is currently uninitialized, thus there are two ways
of indicating that "everything's OK": 0 and 1. This is a bit of a burden.
If a devce driver wants to check if the pci channel is in a working or a
disconnected state, the driver writer must perform checks similar to
if((pdev->error_state != 0) &&
(pdev->error_state != pci_channel_io_normal)) {
whatever();
}
which is rather akward. The first check is needed because stuct pci_dev is
inited to all-zeros. The scond is needed because the error recovery will
set the state to pci_channel_io_normal (which is not zero).
This patch fixes this awkwardness.

We all failed to notice that Franck's recent update to usb-storage allowed
an URB to complete after its context data was no longer valid. This patch
(as746) makes the driver wait for the URB to complete whenever there's a
timeout.
Although timeouts in usb-storage are relatively uncommon, they do occur.
Without this patch the code in 2.6.18-rc1 will fault within an interrupt
handler, which is not nice at all.

Subject: [PATCH 0232/1026] [PATCH] mmap zero-length hugetlb file with
PROT_NONE to protect a hugetlb virtual area
Sometimes, applications need below call to be successful although
"/mnt/hugepages/file1" doesn't exist.
fd = open("/mnt/hugepages/file1", O_CREAT|O_RDWR, 0755);
*addr = mmap(NULL, 0x1024*1024*256, PROT_NONE, 0, fd, 0);
As for regular pages (or files), above call does work, but as for huge
pages, above call would fail because hugetlbfs_file_mmap would fail if
(!(vma->vm_flags & VM_WRITE) && len > inode->i_size).
This capability on huge page is useful on ia64 when the process wants to
protect one area on region 4, so other threads couldn't read/write this
area. A famous JVM (Java Virtual Machine) implementation on IA64 needs the
capability.

Fix some FRV arch compile errors, including:
(*) Marking nr_kernel_pages as __meminitdata so that references to it end up
being properly calculated rather than being assumed to be in the small
data section (and thus calculated wrt the GP register). Not doing this
causes the linker to emit errors as the offset is too big to fit into the
load instruction.
(*) Move pm_power_off into an unconditionally compiled .c file as it's now
unconditionally accessed.
(*) Declare frv_change_cmode() in a header file rather than in a .c file, and
declare it asmlinkage.

Subject: [PATCH 0235/1026] [PATCH] NOMMU: Fix execution off of ramfs with
mmap()
Fix execution through the FDPIC binfmt of programs stored on ramfs by
preventing the ramfs mmap() returning successfully on a private mapping of
a ramfs file. This causes NOMMU mmap to make a copy of the mapped portion
of the file and map that instead.
This could be improved by granting direct mapping access to read-only
private mappings for which the data is stored on a contiguous run of pages.
However, this is only likely to be the case if the file was extended with
truncate before being written.
ramfs is left to map the file directly for shared mappings so that SYSV IPC
and POSIX shared memory both still work.

Adjust the ELF-FDPIC binfmt driver to conform much more to the CodingStyle,
silly though it may be.
Further changes:
(*) Drop the casts to long for addresses in kdebug() statements (they're
unsigned long already).
(*) Use extra variables to avoid expressions longer than 80 chars by splitting
the statement into multiple statements and letting the compiler optimise
them back together.
(*) Eliminate duplicate call of ksize() when working out how much space was
actually allocated for the stack.
(*) Discard the commented-out load_shlib prototype and op pointer as this will
not be supported in ELF-FDPIC for the foreseeable future.

CONFIG_PM_STD_PARTITION=""
Matthew Wilcox notified me that CONFIG_PM_STD_PARTITION="/dev/hda2" in the
i386 defconfig wasn't a good idea (especially since it prevented booting
for him due to another bug).
This patch sets CONFIG_PM_STD_PARTITION="" in the i386 defconfig.

Subject: [PATCH 0243/1026] [PATCH] swsusp: do not use memcpy for snapshotting
memory
swsusp should not use memcpy for snapshotting memory, because on some
architectures memcpy may increase preempt_count (i386 does this when
CONFIG_X86_USE_3DNOW is set). Then, as a result, wrong value of preempt_count
is stored in the image.
Replace memcpy in copy_data_pages with an open-coded loop.

Subject: [PATCH 0248/1026] [PATCH] uml: clean up address space limits code
I was looking at the code of the UML and more precisely at the functions
set_task_sizes_tt and set_task_sizes_skas. I noticed that these 2 functions
take a paramater (arg) which is not used : the function is always called with
the value 0.
I suppose that this value might change in the future (or even can be
configured), so I added a constant in mem_user.h file.
Also, I rounded CONFIG_HOST_TASk_SIZE to a 4M.

Subject: [PATCH 0249/1026] [PATCH] uml: timer initialization cleanup
This cleans up the mess that is the timer initialization. There used to be
two timer handlers - one that basically ran during delay loop calibration and
one that handled the timer afterwards. There were also two sets of timer
initialization code - one that starts in user code and calls into the kernel
side of the house, and one that starts in kernel code and calls user code.
This eliminates one timer handler and consolidates the two sets of
initialization code.

Subject: [PATCH 0251/1026] [PATCH] uml: fix static binary segfault
When UML is built as a static binary, it segfaults when run. The reason is
that a memory hole that is present in dynamic binaries isn't there in static
binaries, and it contains essential stuff.
This fix removes the code which maps some anonymous memory into that hole and
cleans up some related code.

Subject: [PATCH 0258/1026] [PATCH] uml: remove os_isatty
os_isatty can be made to disappear by moving maybe_sigio_broken from kernel to
user code. This also lets write_sigio_workaround become static.

Subject: [PATCH 0259/1026] [PATCH] uml: fix exitcall ordering bug
This fixes an exitcall ordering bug - calls to ignore_sigio_fd can come from
exitcalls that come after the sigio thread has been killed. This would cause
shutdown to hang or crash.
Fixed by having ignore_sigio_fd check that the thread is present before trying
to communicate with it.

Subject: [PATCH 0270/1026] [PATCH] Fix and enable EDAC sysfs operation
When EDAC was first introduced into the kernel it had a sysfs interface,
but due to some problems it was disabled in 2.6.16 and remained disabled in
2.6.17.
With feedback, several of the control and attribute files of that interface
had some good constructive feedback. PCI Blacklist/Whitelist was a major
set which has design issues and it has been removed in this patch. Instead
of storing PCI broken parity status in EDAC, it has been moved to the
pci_dev structure itself by a previous PCI patch. A future patch will
enable that feature in EDAC by utilizing the pci_dev info.
The sysfs is now enabled in this patch, with a minimal set of control and
attribute files for examining EDAC state and for enabling/disabling the
memory and PCI operations.
The Documentation for EDAC has also been updated to reflect the new state
of EDAC operation.

- This control file allows for a list of PCI devices to be
- skipped for scanning.
- The list is a line of hexadecimal VENDOR and DEVICE ID tuples:
-

-
- One or more can be inserted, separated by a comma.
-
- To write the above list doing the following as one command line:

=======================================================================
-
-PCI Vendor and Devices IDs can be obtained with the lspci command. Using
-the -n option lspci will display the vendor and device IDs. The system
-administrator will have to determine which devices should be scanned or
-skipped.
-
-
-
-The two lists (white and black) are prioritized. blacklist is the lower
-priority and will NOT be utilized when a whitelist has been set.
-Turn OFF a whitelist by an empty echo command:
-
- echo > /sys/devices/system/edac/pci/pci_parity_whitelist
-
-and any previous blacklist will be utilized.

Subject: [PATCH 0271/1026] [PATCH] make valid_mmap_phys_addr_range() take a
pfn
Newer ARMs have a 40 bit physical address space, but mapping physical
memory above 4G needs a special page table format which we (currently?) do
not use for userspace mappings, so what happens instead is that mapping an
address >= 4G will happily discard the upper bits and wrap.
There is a valid_mmap_phys_addr_range() arch hook where we could check for
>= 4G addresses and deny the mapping, but this hook takes an unsigned long
address:
static inline int valid_mmap_phys_addr_range(unsigned long addr, size_t size);
And drivers/char/mem.c:mmap_mem() calls it like this:
static int mmap_mem(struct file * file, struct vm_area_struct * vma)
{
size_t size = vma->vm_end - vma->vm_start;
if (!valid_mmap_phys_addr_range(vma->vm_pgoff << PAGE_SHIFT, size))
So that's not much help either.
This patch makes the hook take a pfn instead of a phys address.

Subject: [PATCH 0273/1026] [PATCH] fix weird logic in alloc_fdtable()
There's a fairly obvious infinite loop in there.
Also, use roundup_pow_of_two() rather than open-coding stuff.

Add LED Class device support for the Soekris net48xx Error LED. Tested
only on a net4801, but should work on a net4826 as well. I'd love to find
a way of detecting a Soekris net48xx device but there is no DMI or any
Soekris-specific PCI devices.

Subject: [PATCH 0279/1026] [PATCH] pc8736x_gpio: fix re-modprobe errors: undo
region reservation
Fix module-init-func by repairing usage of platform_device_del/put in
module-exit-func. IOW, it imitates Ingo's 'mishaps' patch, which fixed the
module-init-func's undo handling.
Also fixes lack of release_region to undo the earlier registration.
Also starts to 'use a cdev' which was originally intended (its present in
scx200_gpio). Code compiles and runs, exhibits a lesser error than
previously. (re-register-chrdev fails)
Since I had to add "include <linux/cdev.h>", I went ahead and made 2
tweaks that fell into diff-context-window:
- remove include <linux/config.h> everyone's doing it
- copyright updates - current date is 'wrong'

- Switch from register_chrdev() to (register|alloc)_chrdev_region().
- use a cdev. This was intended for original patchset, but was
overlooked.
We use a single cdev for all pins (minor device-numbers), as gleaned
from cs5535_gpio, and in contrast to whats currently done in scx200_gpio
(which I'll fix soon)

Subject: [PATCH 0281/1026] [PATCH] snsc: switch from force_sig to kill_proc
Currently the snsc driver uses force_sig to send init a SIGPWR when the
system overheats. This patch switches it to kill_proc instead which has
the following advantages:
(1) gets rid of one of the last remaining tasklist_lock users
in modular code
(2) simplifies the snsc code significantly
The downside is that an init implementation could in theory block SIGPWR
and it would not get delivered. The sysvinit code used by all major
distributions doesn't do this and blocking this signal in init would be a
rather stupid thing to do.

Subject: [PATCH 0282/1026] [PATCH] disallow modular binfmt_elf32
Currently most architectures either always build binfmt_elf32 in the kernel
image or make it a boolean option. Only sparc64 and s390 allow to build it
modularly. This patch turns the option into a boolean aswell because elf
requires various symbols that shouldn't be available to modules. The most
urgent one is tasklist_lock whos export this patch series kills, but there
are others like force_sgi aswell.
Note that sparc doesn't allow a modular 32bit a.out handler either, and
that would be the more useful case as only few people want 32bit sunos
compatibility and 99.9% of all sparc64 users need 32bit linux native elf
support.

Subject: [PATCH 0287/1026] [PATCH] lockdep: disable lock debugging when kernel
state becomes untrusted
Disable lockdep debugging in two situations where the integrity of the
kernel no longer is guaranteed: when oopsing and when hitting a
tainting-condition. The goal is to not get weird lockdep traces that don't
make sense or are otherwise undebuggable, to not waste time.
Lockdep assumes that the previous state it knows about is valid to operate,
which is why lockdep turns itself off after the first violation it reports,
after that point it can no longer make that assumption.
A kernel oops means that the integrity of the kernel compromised; in
addition anything lockdep would report is of lesser importance than the
oops.
All the tainting conditions are of similar integrity-violating nature and
also make debugging/diagnosing more difficult.

- * TCP Vegas congestion control
- *
- * This is based on the congestion detection/avoidance scheme described in
- * Lawrence S. Brakmo and Larry L. Peterson.
- * "TCP Vegas: End to end congestion avoidance on a global internet."
- * IEEE Journal on Selected Areas in Communication, 13(8):1465--1480,
- * October 1995. Available from:
- * ftp://ftp.cs.arizona.edu/xkernel/Papers/jsac.ps
- *
- * See http://www.cs.arizona.edu/xkernel/ for their implementation.
- * The main aspects that distinguish this implementation from the
- * Arizona Vegas implementation are:
- * o We do not change the loss detection or recovery mechanisms of
- * Linux in any way. Linux already recovers from losses quite well,
- * using fine-grained timers, NewReno, and FACK.
- * o To avoid the performance penalty imposed by increasing cwnd
- * only every-other RTT during slow start, we increase during
- * every RTT during slow start, just like Reno.
- * o Largely to allow continuous cwnd growth during slow start,
- * we use the rate at which ACKs come back as the "actual"
- * rate, rather than the rate at which data is sent.
- * o To speed convergence to the right rate, we set the cwnd
- * to achieve the right ("actual") rate when we exit slow start.
- * o To filter out the noise caused by delayed ACKs, we use the
- * minimum RTT sample observed during the last RTT to calculate
- * the actual rate.
- * o When the sender re-starts from idle, it waits until it has
- * received ACKs for an entire flight of new data before making
- * a cwnd adjustment decision. The original Vegas implementation
- * assumed senders never went idle.
- *
- *
- * TCP Compound based on TCP Vegas

Subject: [PATCH 0296/1026] [PATCH] x86_64: Bring x86-64 ia32 emul in sync with
i386 on READ_IMPLIES_EXEC enabling
Currently ia32 binaries behave differently with respect to enabling
READ_IMPLIES_EXEC. On i386 a binary with the exec_stack flag set is
executed with READ_IMPLIES_EXEC enabled as well. The same binary
executes without READ_IMPLIES_EXEC on x86-64.
This causes binaries that work on i386 to fail on x86-64 which goes
somewhat against the whole 32 bit emulation idea.
It has been argued that READ_IMPLIES_EXEC should not be enabled at all
for binaries that have the exec_stack flag. Which is probably a valid
point. However until this is clarified I think x86-64 should behave the
same for ia32 binaries as i386.
The following patch brings x86-64 in sync with i386 for ia32 binaries.

Add it for P4 model 6 - reported to work and have a similar PMU to
earlier P4s.
Add an p4force=1 module override parameter for future use.
We had a discussion about that earlier - it's a trade off between the
PMU staying compatible or not. I think the force parameter is a
reasonable compromise.

Subject: [PATCH 0306/1026] [ARM] Allow Versatile to be built for AB and PB
If a configuration was chosen to support both the Versatile
AB and PB boards, the result would write to registers not
available on the PB version of the board. Resolve this by
using machine_is_xxx().
Also, for the CLCD, despite how the code looks, both the AB
and PB access the same location to control the clock rate -
it's just called something different between the two board

Patch from Pavel Machek
From: Dirk Opfer <Dirk@Opfer-Online.de>
Fix ucb initialization on collie. Wrong frequency was used and that
led to things not working quite correctly. (I had to actually disable
checks in my tree to get it to boot). It now includes all the
neccessary parts to get it to compile :-).

Using the port_id for the channel is completely unnecessary since the

the mptsas driver on to virtual channel 1 for its raid devices.

__builtin_trap() has the archictecture defined backend in gcc since gcc 3.3.
To make sure the kernel builds with gcc 3.2 as well, use the old style BUG()
statement if compiled with older gcc versions.

Subject: [PATCH 0315/1026] [S390] subchannel register/unregister mutex.
Add a reg_mutex to prevent unregistering a subchannel before it has been
registered. Since 2.6.17, we've seen oopses in kslowcrw when a device is
found to be not operational during sense id when doing initial device
recognition; it is not clear yet why that particular problem was not (yet)
observed with earlier kernels...

Subject: [PATCH 0318/1026] [S390] xpram module parameter parsing.
The module parameters for xpram are not or in a wrong way parsed.
The xpram module uses the module_param_array directive with an int
parameter which causes the kernel to automatically parse the passed
numbers. This will cause errors if arguments are omitted or cause
wrong results if arguments have size qualifiers.
Use module_param_array with charp and parse the arguments later.

Subject: [PATCH 0319/1026] [S390] path grouping and path verifications fixes.
1. Multipath devices for which SetPGID is not supported are not handled well.
Use NOP ccws for path verification (sans path grouping) when SetPGID is not
supported.
2. Check for PGIDs already set with SensePGID on _all_ paths (not just the
first one) and try to find a common one. Moan if no common PGID can be
found (and use NOP verification). If no PGIDs have been set, use the css
global PGID (as before). (Rationale: SetPGID will get a command reject if
the PGID it tries to set does not match the already set PGID.)
3. Immediately before reboot, issue RESET CHANNEL PATH (rcp) on all chpids. This
will remove the old PGIDs. rcp will generate solicited CRWs which can be
savely ignored by the machine check handler (all other actions create
unsolicited CRWs).

Subject: [PATCH 0321/1026] Add PIIX4 APCI quirk for the 440MX chipset too
This is confirmed to fix a hang due to PCI resource conflicts with
setting up the Cardbus bridge on old laptops with the 440MX chipsets.
Original report by Alessio Sangalli, lspci debugging help by Pekka
Enberg, and trial patch suggested by Daniel Ritz:
"From the docs available i would _guess_ this thing is really similar
to the 82443BX/82371AB combination. at least the SMBus base address
register is hidden at the very same place (32bit at 0x90 in function
3 of the "south" brigde)"
The dang thing is largely undocumented, but the patch was corroborated
by Asit Mallick:
"I am trying to find the register information. 440MX is an integration of
440BX north-bridge without AGP and PIIX4E (82371EB). PIIX4 quirk
should cover the ACPI and SMBus related I/O registers."
and verified to fix the problem by Alessio.

Subject: [PATCH 0323/1026] [SCSI] NCR_D700: misc fixes (section and argument
ordering)
Apparently the D700 has had an argument ordering issue for quite a while
which can cause it to get the wrong scsi_id (I just got an unbootable
voyager system because of this). Hopefully this patch also fixes up all
the sectional mismatches within the driver.

Subject: [PATCH 0340/1026] [PATCH] Fix prctl privilege escalation and
suid_dumpable (CVE-2006-2451)
Based on a patch from Ernie Petrides
During security research, Red Hat discovered a behavioral flaw in core
dump handling. A local user could create a program that would cause a
core file to be dumped into a directory they would not normally have
permissions to write to. This could lead to a denial of service (disk
consumption), or allow the local user to gain root privileges.
The prctl() system call should never allow to set "dumpable" to the
value 2. Especially not for non-privileged users.
This can be split into three cases:
1) running as root -- then core dumps will already be done as root,
and so prctl(PR_SET_DUMPABLE, 2) is not useful
2) running as non-root w/setuid-to-root -- this is the debatable case
3) running as non-root w/setuid-to-non-root -- then you definitely
do NOT want "dumpable" to get set to 2 because you have the
privilege escalation vulnerability
With case #2, the only potential usefulness is for a program that has
designed to run with higher privilege (than the user invoking it) that
wants to be able to create root-owned root-validated core dumps. This
might be useful as a debugging aid, but would only be safe if the program
had done a chdir() to a safe directory.
There is no benefit to a production setuid-to-root utility, because it
shouldn't be dumping core in the first place. If this is true, then the
same debugging aid could also be accomplished with the "suid_dumpable"
sysctl.

During the recent discussion of taking 'volatile' off of the spinlock, I
noticed that while most arches #define cpu_relax() such that it implies
barrier(), some arches define cpu_relax() to be empty.
This patch changes the definition of cpu_relax() for frv, h8300, m68knommu,
sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

Subject: [PATCH 0348/1026] [PATCH] ide: fix Jmicron support
Prior to 2.6.18rc1 you could install with devices on a JMicron chipset
using the "all-generic-ide" option. As of this kernel the AHCI driver
grabs the controller and rams it into AHCI mode losing the PATA ports
and making CD drives and the like vanish. The all-generic-ide option
fails because the AHCI driver grabbed the PCI device and reconfigured
it.
To fix this three things are needed.
#1 We must put the chip into dual function mode
#2 The AHCI driver must grab only function 0 (already in your rc1 tree)
#3 Something must grab the PATA ports
The attached patch is the minimal risk edition of this. It puts the chip
into dual function mode so that AHCI will grab the SATA ports without
losing the PATA ports. To keep the risk as low as possible the third
patch adds the PCI identifiers for the PATA port and the FN check to the
ide-generic driver. There is a more featured jmicron driver on its way
but that adds risk and the ide-generic support is sufficient to install
and run a system.
The actual chip setup done by the quirk is the precise setup recommended
by the vendor.
(The JMB368 appears only in the ide-generic entry as it has no AHCI so
does not need the quirk)

harmless but triggers lockdep. Either way, reordering the code a

Subject: [PATCH 0354/1026] [TCP] tcp_highspeed: Fix AI updates.
I think there is still a problem with the AIMD parameter update in
HighSpeed TCP code.
Line 125~138 of the code (net/ipv4/tcp_highspeed.c):
/* Update AIMD parameters */
if (tp->snd_cwnd > hstcp_aimd_vals[ca->ai].cwnd) {
while (tp->snd_cwnd > hstcp_aimd_vals[ca->ai].cwnd &&
ca->ai < HSTCP_AIMD_MAX - 1)
ca->ai++;
} else if (tp->snd_cwnd < hstcp_aimd_vals[ca->ai].cwnd) {
while (tp->snd_cwnd > hstcp_aimd_vals[ca->ai].cwnd &&
ca->ai > 0)
ca->ai--;
In fact, the second part (decreasing ca->ai) never decreases since the
while loop's inequality is in the reverse direction. This leads to
unfairness with multiple flows (once a flow happens to enjoy a higher
ca->ai, it keeps enjoying that even its cwnd decreases)
Here is a tentative fix (I also added a comment, trying to keep the
change clear):

Subject: [PATCH 0355/1026] [IPV6]: Use ipv6_addr_src_scope for link address
sorting.
In the source address selection, the address must be sorted
from global to node-local.
But, ifp->scope is different from the scope for source address
selection.
2001::1 fe80::1 ::1
ifp->scope 0 0x02 0x01
ipv6_addr_src_scope(&ifp->addr) 0x0e 0x02 0x01
So, we need to use ipv6_addr_src_scope(&ifp->addr) for sorting.
And, for backward compatibility, addresses should be sorted from
new one to old one.

Subject: [PATCH 0356/1026] [IPCOMP]: Fix truesize after decompression
The truesize check has uncovered the fact that we forgot to update truesize
after pskb_expand_head. Unfortunately pskb_expand_head can't update it for
us because it's used in all sorts of different contexts, some of which would
not allow truesize to be updated by itself.
So the solution for now is to simply update it in IPComp.
This patch also changes skb_put to __skb_put since we've just expanded
tailroom by exactly that amount so we know it's there (but gcc does not).

There were some tso bugs that only showed up with heavy load and 16kB
pages that this patch fixes by making the driver's internal use count
of descriptors match the count that it was estimating it needed using
the DESC_NEEDED macro. This bug caused NETDEV_WATCHDOG resets aka
tx timeouts.

Subject: [PATCH 0373/1026] [Bluetooth] Let BT_HIDP depend on INPUT
This patch lets BT_HIDP depend on instead of select INPUT. This fixes
the following warning during an s390 build:
net/bluetooth/hidp/Kconfig:4:warning: 'select' used by config symbol
'BT_HIDP' refer to undefined symbol 'INPUT'
A dependency on INPUT also implies !S390 (and therefore makes the
explicit dependency obsolete) since INPUT is not available on s390.
The practical difference should be nearly zero, since INPUT is always
set to y unless EMBEDDED=y (or S390=y).

Subject: [PATCH 0384/1026] [PATCH] sky2: optimize receive restart
When the driver handles multiple packets per NAPI poll, it is
better to reload the receive ring, then tell the hardware. Otherwise,
under packet storm with flow control, the driver/hardware will degrade
down to one packet getting through per pause-exchange.
Likewise on transmit, don't wakeup until a little more than minimum
ring space is available.

Subject: [PATCH 0388/1026] [PATCH] scx200_acb: Fix the block transactions
The scx200_acb i2c bus driver pretends to support SMBus block
transactions, but in fact it implements the more simple I2C block
transactions. Additionally, it lacks sanity checks on the length
of the block transactions, which could lead to a buffer overrun.
This fixes an oops reported by Alexander Atanasov:

Subject: [PATCH 0392/1026] [PATCH] i2c: Handle i2c_add_adapter failure in i2c
algorithm drivers
Content-Disposition: inline; filename=i2c-algo-error-handling-fix.patch
It is possible for i2c_add_adapter() to fail. Several I2C algorithm
drivers ignore that fact. This (compile-tested only) patch fixes them.

Subject: [PATCH 0396/1026] [PATCH] hwmon: Fix for first generation Abit uGuru
chips
Now that the abituguru driver is seeing some more widespread testing
it has turned out that one the first generation of Abit uGuru
motherboards, with uGuru revision 1, the autodetect bank1 sensor type
code doesn't (always) work. This patch adds a module param to override
the autodetect, and it adds validity checks for the value of the 2
other autodetection override module params. An example of howto use
the new param can be found here:

Subject: [PATCH 0399/1026] [PATCH] USB: au1200: EHCI and OHCI fixes
I received an DBAU1200 eval kit from AMD a few days ago and tried to
enable the USB2 port, but the current linux-2.6 GIT did not even
compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and
CONFIG_USB_OHCI set.
Furthermore, in ehci-hcd.c, platform_driver_register() was called with
an improper argument of type 'struct device_driver *' which of course
ended up in a kernel oops. How could that ever have worked on your
machines?
Anyway, here's a trivial patch that makes the USB subsystem working
on my board for both OHCI and EHCI.
It also removes the /* FIXME use "struct platform_driver" */.

Subject: [PATCH 0407/1026] [PATCH] USB: fix visor leaks
This patch fixes blatant leaks in visor driver and makes it report
mode sensible things in ->write_room (this is only needed if your visor
is a terminal though).
It is made to fit into 80 columns with a temporary variable.
Might even save a few instructions...

Subject: [PATCH 0408/1026] [PATCH] USB: Add some basic WUSB definitions
This patch adds basic Wireless USB 1.0 definitions to usb_ch9.h that
fit into the existing set of declarations. Boils down to two new
recipients for requests (ports and remote pipes), rpipe reset and
abort request codes and wire adapter and remote pipe descriptor
types.
Wire adapters are the USB <-> Wireless USB adaptors; remote pipes
are used by those adapters to pipe the host <-> endpoint traffic.

Universal-2 cable in pl2303
The Susteen Datapilot cable
(http://www.susteen.com/productdetail/71/producthl/Notempty) has an
internal pl2303 to communicate with a set of dummy connector-ends that
connect to a variety of cell phones. I've found that it works right out
of the box by simply adding the product/vendor id to the pl2303 driver.

Subject: [PATCH 0411/1026] [PATCH] USB: rename Cypress CY7C63xxx driver to
proper name and fix up some tiny things
This is a new driver for the Cypress CY7C63xxx mirco controller series.
It currently supports the pre-programmed CYC63001A-PC by AK Modul-Bus
GmbH. It's based on a kernel 2.4 driver (cyport) by Marcus Maul which I
ported to kernel 2.6 using sysfs. I intend to support more controllers
of this family (and more features) as soon as I get hold of the required
IDs etc. Please see the source code's header for more information.

Subject: [PATCH 0413/1026] [PATCH] usb-storage: fix race between reset and
disconnect
My recent patch converting usb-storage to use
usb_reset_composite_device() added a bug, a race between reset and
disconnect. It was necessary to drop the private lock while executing a
reset, and if a disconnect occurs at that time it will cause a crash.
This patch (as722) fixes the problem by explicitly checking for an early
termination after executing each command.

Subject: [PATCH 0420/1026] [PATCH] USB serial visor: fix race in open/close
The anti user-DoS mechanism in the USB serial 'visor' driver can fail in
the following way:
visor_open: priv->outstanding_urbs = 0
visor_write: ++priv->outstanding_urbs
visor_close:
visor_open: priv->outstanding_urbs = 0
visor_write_bulk_callback: --priv->outstanding_urbs
So priv->outstanding_urbs ends up as (unsigned long)(-1). Not good!
I haven't seen this happen with the visor driver as I don't have the
hardware, but I have seen it while testing a patch to implement the same
functionality in the ftdi_sio driver (patch not yet submitted).
The fix is pretty simple: don't reinitialize outstanding_urbs in
visor_open. (Again, I haven't tested the fix in visor, but I have
tested it in ftdi_sio.)

Subject: [PATCH 0421/1026] [PATCH] USB serial ftdi_sio: Prevent userspace DoS
This patch limits the amount of outstanding 'write' data that can be
queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or
simple accidents) that use up all the system memory by writing lots of
data to the serial port.
The original patch was by Guillaume Autran, who in turn based it on the
same mechanism implemented in the 'visor' driver. I (Ian Abbott)
re-targeted the patch to the latest sources, fixed a couple of errors,
renamed his new structure members, and updated the implementations of
the 'write_room' and 'chars_in_buffer' methods to take account of the
number of outstanding 'write' bytes. It seems to work fine, though at
low baud rates it is still possible to queue up an amount of data that
takes an age to shift (a job for another day!).

Subject: [PATCH 0425/1026] [PATCH] USB: ehci: fix bogus alteration of a local
variable
In a rare and all-but-unused path, the EHCI driver could reuse a variable
in a way that'd make trouble. Specifically, if the first root hub port
gets an overcurrent event (rare) during a remote wakeup scenario (all but
unused in today's Linux, except for folk working with suspend-to-RAM and
similar sleep states), that would look like a fatal error which would shut
down the controller. Fix by not reusing that variable.

Subject: [PATCH 0426/1026] [PATCH] USB: ipaq.c bugfixes
This patch fixes several problems in the ipaq.c driver with connecting
and disconnecting pocketpc devices:
* The read urb stayed active if the connect failed, causing nullpointer
dereferences later on.
* If a write failed, the driver continued as if nothing happened. Now it
handles that case the same way as other usb serial devices (fix by
Luiz Fernando N. Capitulino <lcapitulino@mandriva.com.br>)

Subject: [PATCH 0427/1026] [PATCH] USB: ipaq.c timing parameters
Adds configurable waiting periods to the ipaq connection code. These are
not needed when the pocketpc device is running normally when plugged in,
but they need extra delays if they are physically connected while
rebooting.
There are two parameters :
* initial_wait : this is the delay before the driver attemts to start the
connection. This is needed because the pocktpc device takes much
longer to boot if the driver starts sending control packets too soon.
* connect_retries : this is the number of times the control urb is
retried before finally giving up. The patch also adds a 1 second delay
between retries.
I'm not sure if the cases where this patch is useful are general enough
to include this in the kernel.

Subject: [PATCH 0430/1026] [PATCH] USB: ipw.c driver fix
The below patch fixes the ipw module in kernel 2.6.17 for me; without
this change it simply does not work at all (all but the first writes are
refused because write_urb_busy is always 1).
This problem was there in 2.6.15 as well, but at that point I used the
(updated) ipw.c, version 0.4, from
http://www.neology.co.za/products/opensource/ipwireless/ which no longer
compiles with 2.6.17. It can be made to after a few changes but
obviously it's easier if the built-in ipw driver works instead of having
to download one from the neology site.

Subject: [PATCH 0433/1026] [PATCH] USB: add ZyXEL vendor/product ID to rtl8150
driver
I just got a "ZyXEL Prestige USB Adapter" that is actually RTL8150
adapter. Here is the relevant /proc/bus/usb/devices output (after
adding the vendor/product IDs to the driver):
T: Bus=01 Lev=02 Prnt=02 Port=02 Cnt=02 Dev#=119 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=0586 ProdID=401a Rev= 1.00
S: Manufacturer=ZyXEL
S: Product=Prestige USB Adapter
S: SerialNumber=1027
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=120mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=ff Driver=rtl8150
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 8 Ivl=1ms
This patch adds the ZyXEL vendor ID to the rtl8150.c driver. The
device has absolutely no identifying marks on the outside for model
type, just a serial number, and I can't find anything on ZyXEL's
website, so I called the product ID PRODUCT_ID_PRESTIGE to match the
product string.

Subject: [PATCH 0439/1026] [PATCH] USB: gadget section fixups
Recent section changes broke gadget builds on some platforms. This patch
is the best fix that's available until better section markings exist:
- There's a lot of cleanup code that gets used in both init and exit paths;
stop marking it as "__exit".
(Best fix for this would be an "__init_or_exit" section marking, putting
the cleanup in __init when __exit sections get discarded else in __exit.)
- Stop marking the use-once probe routines as "__init" since references
to those routines are not allowed from driver structures. They're now
marked "__devinit", which in practice is a net lose.
(Best fix for this is likely to separate such use-once probe routines
from the driver structure ... but in general, all busses that aren't
hotpluggable will be forced to waste memory for all probe-only code.)
In general these broken section rules waste an average of two to four kBytes
per driver of code bloat ... because none of the relevant code can ever be
reused after module initialization.

Subject: [PATCH 0440/1026] [PATCH] USB: Anydata: Fixes wrong URB callback.
Anydata is using usb_serial_generic_write_bulk_callback() for its
read URB, but it should use usb_serial_generic_read_bulk_callback()
instead (it's a read URB, isn't it?).
Reported by Jon K Hellan <hellan@acm.org>.

Subject: [PATCH 0441/1026] [PATCH] USB: move usb-serial.h to
include/linux/usb/
USB serial outside of the kernel tree can not build properly due to
usb-serial.h being buried down in the source tree. This patch moves the
location of the file to include/linux/usb and fixes up all of the usb
serial drivers to handle the move properly.

Subject: [PATCH 0443/1026] [PATCH] PCI: Clear abnormal poweroff flag on VIA
southbridges, fix resume
Some VIA southbridges contain a flag in the ACPI register space that
indicates whether an abnormal poweroff has occured, presumably with the
intention that it can be cleared on clean shutdown. Some BIOSes check this
flag at resume time, and will re-POST the system rather than jump back to
the OS if it's set. Clearing it at boot time appears to be sufficient.
I'm not sure if drivers/pci/quirks.c is the right place to do it, but I'm
not sure where would be cleaner.

Subject: [PATCH 0445/1026] [PATCH] PCI: PCIE power management quirk
When changing power states from D0->DX and then from DX->D0, some
Intel PCIE chipsets will cause a device reset to occur. This will
cause problems for any D State other than D3, since any state
information that the driver will expect to be present coming from
a D1 or D2 state will have been cleared. This patch addes a
flag to the pci_dev structure to indicate that devices should
not use states D1 or D2, and will set that flag for the affected
chipsets. This patch also modifies pci_set_power_state() so that
when a device driver tries to set the power state on
a device that is downstream from an affected chipset, or on one
of the affected devices it only allows state changes to or
from D0 & D3. In addition, this patch allows the delay time
between D3->D0 to be changed via a quirk. These chipsets also
need additional time to change states beyond the normal 10ms.

Subject: [PATCH 0452/1026] [PATCH] Revert "ACPI: execute Notify() handlers on
new thread"
This effectively reverts commit b8d35192c55fb055792ff0641408eaaec7c88988
by reverts acpi_os_queue_for_execution() to what it was before that,
except it changes the name to acpi_os_execute() to match ACPICA
20060512.
Signed-off-by: Len Brown <len.brown@intel.com>
[ The thread execution doesn't actually solve the bug it set out to
solve (see
http://bugzilla.kernel.org/show_bug.cgi?id=5534
for more details) because the new events can get caught behind the AML
semaphore or other serialization. And when that happens, the notify
threads keep on piling up until the system dies. ]

This reverts commit 5040cb8b7e61b7a03e8837920b9eb2c839bb1947.
It breaks previously working ide-cs PIO configurations, causing problems
like
ide2: I/O resource 0xF883200E-0xF883200E not free.
ide2: ports already in use, skipping probe
rather than a working kernel.

Subject: [PATCH 0457/1026] [SPARC64]: Fix 2 bugs in sabre_irq_build()
When installing the IRQ pre-handler, we were not setting up the second
argument correctly. It should be a pointer to the sabre_irq_data, not
the config space PIO address.
Furthermore, we only need this pre-handler installed if the device
sits behind a PCI bridge that is not Sabre or Simba/APB.

Subject: [PATCH 0458/1026] [SERIAL] sunsu: Handle keyboard and mouse ports
directly.
The sunsu_ports[] array exists merely to be able to easily
use an integer index to get at the proper serial console
port struct.
We size this only for real ports, not for the keyboard and
mouse, and thus keyboard and mouse port registration would
fail.
Fix this by dynamically allocating the port struct for the
keyboard and mouse, instead of using the sunsu_ports[]
array.

Subject: [PATCH 0460/1026] [SPARC]: Fix OF register translations under sub-PCI
busses.
There is an implicit assumption in the code that ranges will translate
to something that can fit in 2 32-bit cells, or a 64-bit value. For
certain kinds of things below PCI this isn't necessarily true.
Here is what the relevant OF device hierarchy looks like for one of
the serial controllers on an Ultra5:
Node 0xf005f1e0
ranges: 00000000.00000000.00000000.000001fe.01000000.00000000.01000000
01000000.00000000.00000000.000001fe.02000000.00000000.01000000
02000000.00000000.00000000.000001ff.00000000.00000001.00000000
03000000.00000000.00000000.000001ff.00000000.00000001.00000000
device_type: 'pci'
model: 'SUNW,sabre'
Node 0xf005f9d4
device_type: 'pci'
model: 'SUNW,simba'
Node 0xf0060d24
ranges: 00000010.00000000 82010810.00000000.f0000000 01000000
00000014.00000000 82010814.00000000.f1000000 00800000
name: 'ebus'
Node 0xf0062dac
reg: 00000014.003083f8.00000008 --> 0x1ff.f13083f8
device_type: 'serial'
name: 'su'
So the correct translation here is:
1) Match "su" register to second ranges entry of 'ebus', which translates
into a PCI triplet "82010814.00000000.f1000000" of size 00800000, which
gives us "82010814.00000000.f13083f8".
2) Pass-through "SUNW,simba" since it lacks ranges property
3) Match "82010814.00000000.f13083f8" to third ranges property of PCI
controller node 'SUNW,sabre', and we arrive at the final physical
MMIO address of "0x1fff13083f8".
Due to the 2-cell assumption, we couldn't translate to a PCI 3-cell
value, and we couldn't perform a pass-thru on it either.
It was easiest to just stop splitting the ranges application operation
between two methods, ->map and ->translate, and just let ->map do all
the work. That way it would work purely on 32-bit cell arrays instead
of having to "return" some value like a u64.
It's still not %100 correct because the out-of-range check is still
done using the 64 least significant bits of the range and address.
But it does work for all the cases I've thrown at it so far.

Subject: [PATCH 0470/1026] [PATCH] i386: system.h: remove extra semicolons and
fix order
include/asm-i386/system.h has trailing semicolons in some of the
macros that cause legitimate code to fail compilation, so remove
them. Also remove extra blank lines within one group of macros.
And put stts() and clts() back together; they got separated somehow.

Subject: [PATCH 0471/1026] [PATCH] m68knommu: fix result type in get_user()
macro
Keep the result holder variable the same type as the quantity we are
retreiving in the get_user() macro - don't go through a pointer version
of the user space address type.
Using the address type causes problems if the address type was const
(newer versions of gcc quite rightly error out for that condition).

mm/slab.c uses nested locking when dealing with 'off-slab'
caches, in that case it allocates the slab header from the
(on-slab) kmalloc caches. Teach the lock validator about
this by putting all on-slab caches into a separate class.
this patch has no effect on non-lockdep kernels.

As a result of 894673ee6122a3ce1958e1fe096901ba5356a96b, the ARM

to build, with all others erroring out with:

...
Essentially, root_dev.h uses MKDEV and dev_t, but does not include any
headers which provide either of these definitions. The reason it worked
previously is that linux/tty.h just happened to include the required
headers for linux/root_dev.h.

Subject: [PATCH 0498/1026] [MIPS] Sibyte: Improve interrupt latency again for
sb1250/bcm1480
this patch restores the behaviour of the old (assembly-written)
interrupt handler, the handler is left as soon as a single interrupt
cause is handled.

Subject: [PATCH 0504/1026] [MIPS] Do not count pages in holes with sparsemem
With some memory model other than FLATMEM, the single node can
contains some holes so there might be many invalid pages. For
example, with two 256M memory and one 256M hole, some variables
(num_physpage, totalpages, nr_kernel_pages, nr_all_pages, etc.) will
indicate that there are 768MB on this system. This is not desired
because, for example, alloc_large_system_hash() allocates too many
entries.
Use free_area_init_node() with counted zholes_size[] instead of
free_area_init().
For num_physpages, use number of ram pages instead of max_low_pfn.

- *
- * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in

- * 3 Hardware (ignored)
- * 4 Hardware (ignored)
- * 5 Hardware (ignored)
- * 6 Hardware (ignored)
- * 7 R4k timer (what we use)
- *
- * Note: On the SEAD board thing are a little bit different.
- * Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
- * wired to UART1.
- *
- * We handle the IRQ according to _our_ priority which is:
- *
- * Highest ---- R4k Timer
- * Lowest ---- Combined hardware interrupt
- *
- * then we just return, if multiple IRQs are pending then we will just take

Subject: [PATCH 0532/1026] [NET]: Update frag_list in pskb_trim
When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of
the packet, the frag_list is not updated to reflect the trimming. This
will usually work fine until you hit something that uses the packet length
or tail from the frag_list.
Examples include esp_output and ip_fragment.
Another problem caused by this is that you can end up with a linear packet
with a frag_list attached.
It is possible to get away with this if we audit everything to make sure
that they always consult skb->len before going down onto frag_list. In
fact we can do the samething for the paged part as well to avoid copying
the data area of the skb. For now though, let's do the conservative fix
and update frag_list.
Many thanks to Marco Berizzi for helping me to track down this bug.
This 4-year old bug took 3 months to track down. Marco was very patient
indeed :)

This was seen when running netem over loopback, but there are probably
other device cases. Maybe this should go into stable?

concerns
The original suggested fix for netpoll was found to be racy on SMP
kernels. While it is highly unlikely that this race would ever be seen
in the real world due to current netpoll usage models, we implemented
this updated fix to address concerns.

We have a bad interaction with both the kernel and user space being able

part of it, but I expect we'll also make it harder for users to modify
even their "own" files in /proc.

(reproduced in openvz) in:
*filp

And 1 object leaks in
*size-32
*size-64
*size-128
It is the fix for the first one. filp leaks in the bowels of namei.c.
Seems, size-4096 is file table leaking in expand_fdtables.
I have no idea what are the rest and why they show only accompanying
another leaks. Some debugging structs?

Subject: [PATCH 0553/1026] [PATCH] IB/cm: drop REQ when out of memory
If a user of the IB CM returns -ENOMEM from their connection callback, simply
drop the incoming REQ - do not attempt to send a reject. This should allow
the sender to retry the request.

ib_fmr_pool_map_phys gets the virtual address by pointer but never writes
there, and users (e.g. srp) seem to assume this and ignore the value
returned. This patch cleans up the API to get the VA by value, and updates
all users.

Subject: [PATCH 0560/1026] [PATCH] ia64: race flushing icache in COW path
There is a race condition that showed up in a threaded JIT environment.
The situation is that a process with a JIT code page forks, so the page is
marked read-only, then some threads are created in the child. One of the
threads attempts to add a new code block to the JIT page, so a
copy-on-write fault is taken, and the kernel allocates a new page, copies
the data, installs the new pte, and then calls lazy_mmu_prot_update() to
flush caches to make sure that the icache and dcache are in sync.
Unfortunately, the other thread runs right after the new pte is installed,
but before the caches have been flushed. It tries to execute some old JIT
code that was already in this page, but it sees some garbage in the i-cache
from the previous users of the new physical page.
Fix: we must make the caches consistent before installing the pte. This is
an ia64 only fix because lazy_mmu_prot_update() is a no-op on all other
architectures.

Subject: [PATCH 0563/1026] [PATCH] i386 kexec: allow the kexec on panic
support to compile on voyager
This patch removes the foolish assumption that SMP implied local apics.
That assumption is not-true on the Voyager subarch. This makes that
dependency explicit, and allows the code to build.
What gets disabled is just an optimization to get better crash dumps so the
support should work if there is a kernel that will initialization on the
voyager subarch under those harsh conditions.
Hopefully we can figure out how to initialize apics in init_IRQ and remove
the need to disable io_apics and this dependency.

Subject: [PATCH 0564/1026] [PATCH] i386: remove redundant might_sleep() in
user accessors.
On i386, the user space accessor functions copy_from/to_user() both invoke
might_sleep(), do a quick sanity check, and then pass the work on to their
__copy_from/to_user() counterparts, which again invoke might_sleep().
Given that no actual work happens between these two calls, it is best to
eliminate one of the redundant might_sleep()s.

Subject: [PATCH 0568/1026] [PATCH] null-terminate over-long /proc/kallsyms
symbols
Got a customer bug report (https://bugzilla.novell.com/190296) about kernel
symbols longer than 127 characters which end up in a string buffer that is
not NULL terminated, leading to garbage in /proc/kallsyms. Using strlcpy
prevents this from happening, even though such symbols still won't come out
right.
A better fix would be to not use a fixed-size buffer, but it's probably not
worth the trouble. (Modversion'ed symbols even have a length limit of 60.)

This isn't suitable for userspace to see -- the kernel headers are not a
random library of stuff for userspace; they're only there to define the
kernel<->user ABI for system libraries and tools. Anything which _was_
abusing asm/atomic.h from userspace was probably broken anyway -- as it often
didn't even give atomic operation.

There's no excuse for userspace abusing this kernel header -- the kernel's
headers are not intended to provide a library of helper routines for
userspace. Using <asm/io.h> from userspace is broken on most architectures
anyway. Just say 'no'.

Subject: [PATCH 0576/1026] [PATCH] ramdisk blocksize Kconfig entry
Make the ramdisk blocksize configurable at kernel compilation time rather
than only at boot or module load time, like a couple of the other ramdisk
options. I found this handy awhile back but thought little of it, until
recently asked by a few of the testing folks here to be able to do the same
thing for their automated test setups.
The Kconfig comment is largely lifted from comments in rd.c, and hopefully
this will increase the chances of making folks aware that the default value
often isn't a great choice here (for increasing values of PAGE_SIZE, even
moreso).

Subject: [PATCH 0578/1026] [PATCH] lockdep: annotate the BLKPG_DEL_PARTITION
ioctl
The delete partition IOCTL takes the bd_mutex for both the disk and the
partition; these have an obvious hierarchical relationship and this patch
annotates this relationship for lockdep.

Subject: [PATCH 0579/1026] [PATCH] Add try_to_freeze() to rt-test kthreads
When CONFIG_RT_MUTEX_TESTER is enabled kernel refuses to suspend the
machine because it's unable to freeze the rt-test-* threads.
Add try_to_freeze() after schedule() so that the threads will be freezed
correctly; I've tested the patch and it lets the notebook suspends and
resumes nicely.

Christoph Hellwig:
open_softirq just enables a softirq. The softirq array is statically
allocated so to add a new one you would have to patch the kernel. So
there's no point to keep this export at all as any user would have to
patch the enum in include/linux/interrupt.h anyway.

Subject: [PATCH 0582/1026] [PATCH] scx200_gpio: 1 cdev for N minors: cleanup,
prep
this patch is mostly cleanup of scx200_gpio :
- drop #include <linux/config.h>
- s/DEVNAME/DRVNAME/ apparently a convention
- replace variable num_pins with #define MAX_PINS
- s/dev/devid/ to clarify that its a dev_t, not a struct device dev.
- move devid = MKDEV(major,0) into branch where its needed.
2 minor 'changes' :
- reduced MAX_PINS from 64 to 32. Ive never tested other pins, and
theyre all multiplexed with other functions, some of which may be in use
on my soekris 4801, so I dont know what testing should yield.
- +EXPORT_SYMBOL(scx200_access);
This exposes the driver's vtable, which another driver can use along
with #include <linux/nsc_gpio.h>, to manipulate a gpio-pin.

for N
Remove the scx200_gpio's cdev-array & ksalloc, replacing it with a single
static struct cdev, which is sufficient for all the pins.
cdev_put is commented out since kernel wont link properly with it, and its
apparently not needed.
With these patches, this driver continues to work with Chris Boot's
leds_48xx driver.

On systems with block devices containing a slash (virtual dasd, cciss,

the / to ! for use in the sysfs tree. This patch uses that convention.

Subject: [PATCH 0588/1026] [PATCH] Convert idr's internal locking to _irqsave
variant
Currently, the code in lib/idr.c uses a bare spin_lock(&idp->lock) to do
internal locking. This is a nasty trap for code that might call idr
functions from different contexts; for example, it seems perfectly
reasonable to call idr_get_new() from process context and idr_remove() from
interrupt context -- but with the current locking this would lead to a
potential deadlock.
The simplest fix for this is to just convert the idr locking to use
spin_lock_irqsave().
In particular, this fixes a very complicated locking issue detected by
lockdep, involving the ib_ipoib driver's priv->lock and dev->_xmit_lock,
which get involved with the ib_sa module's query_idr.lock.

Subject: [PATCH 0594/1026] [PATCH] lockdep: core, fix rq-lock handling on
__ARCH_WANT_UNLOCKED_CTXSW
On platforms that have __ARCH_WANT_UNLOCKED_CTXSW set and want to implement
lock validator support there's a bug in rq->lock handling: in this case we
dont 'carry over' the runqueue lock into another task - but still we did a
spinlock_release() of it. Fix this by making the spinlock_release() in
context_switch() dependent on !__ARCH_WANT_UNLOCKED_CTXSW.
(Reported by Ralf Baechle on MIPS, which has __ARCH_WANT_UNLOCKED_CTXSW.
This fixes a lockdep-internal BUG message on such platforms.)

Subject: [PATCH 0602/1026] [PATCH] Fix security check for joint context= and
fscontext= mount options
After some discussion on the actual meaning of the filesystem class
security check in try context mount it was determined that the checks for
the context= mount options were not correct if fscontext mount option had
already been used.
When labeling the superblock we should be checking relabel_from and
relabel_to. But if the superblock has already been labeled (with
fscontext) then context= is actually labeling the inodes, and so we should
be checking relabel_from and associate. This patch fixes which checks are
called depending on the mount options.

Subject: [PATCH 0605/1026] [PATCH] per-task-delay-accounting: setup
Initialization code related to collection of per-task "delay" statistics which
measure how long it had to wait for cpu, sync block io, swapping etc. The
collection of statistics and the interface are in other patches. This patch
sets up the data structures and allows the statistics collection to be
disabled through a kernel boot parameter.

Subject: [PATCH 0606/1026] [PATCH] per-task-delay-accounting: sync block I/O
and swapin delay collection
Unlike earlier iterations of the delay accounting patches, now delays are only
collected for the actual I/O waits rather than try and cover the delays seen
in I/O submission paths.
Account separately for block I/O delays incurred as a result of swapin page
faults whose frequency can be affected by the task/process' rss limit. Hence
swapin delays can act as feedback for rss limit changes independent of I/O
priority changes.

Subject: [PATCH 0609/1026] [PATCH] per-task-delay-accounting: taskstats
interface
Create a "taskstats" interface based on generic netlink (NETLINK_GENERIC
family), for getting statistics of tasks and thread groups during their
lifetime and when they exit. The interface is intended for use by multiple
accounting packages though it is being created in the context of delay
accounting.
This patch creates the interface without populating the fields of the data
that is sent to the user in response to a command or upon the exit of a task.
Each accounting package interested in using taskstats has to provide an
additional patch to add its stats to the common structure.

+Per-task statistics interface
+-----------------------------
+
+
+Taskstats is a netlink-based interface for sending per-task and
+per-process statistics from the kernel to userspace.
+
+Taskstats was designed for the following benefits:
+
+- efficiently provide statistics during lifetime of a task and on its exit
+- unified interface for multiple accounting subsystems
+- extensibility for use by future accounting patches
+
+Terminology
+-----------
+
+"pid", "tid" and "task" are used interchangeably and refer to the standard
+Linux task defined by struct task_struct. per-pid stats are the same as
+per-task stats.
+
+"tgid", "process" and "thread group" are used interchangeably and refer to the
+tasks that share an mm_struct i.e. the traditional Unix process. Despite the
+use of tgid, there is no special treatment for the task that is thread group
+leader - a process is deemed alive as long as it has any task belonging to it.
+
+Usage
+-----
+
+To get statistics during task's lifetime, userspace opens a unicast netlink
+socket (NETLINK_GENERIC family) and sends commands specifying a pid or a tgid.
+The response contains statistics for a task (if pid is specified) or the sum of
+statistics for all tasks of the process (if tgid is specified).
+
+To obtain statistics for tasks which are exiting, userspace opens a multicast
+netlink socket. Each time a task exits, two records are sent by the kernel to
+each listener on the multicast socket. The first the per-pid task's statistics
+and the second is the sum for all tasks of the process to which the task
+belongs (the task does not need to be the thread group leader). The need for
+per-tgid stats to be sent for each exiting task is explained in the per-tgid
+stats section below.
+
+
+Interface
+---------
+
+The user-kernel interface is encapsulated in include/linux/taskstats.h
+
+To avoid this documentation becoming obsolete as the interface evolves, only
+an outline of the current version is given. taskstats.h always overrides the
+description here.
+
+struct taskstats is the common accounting structure for both per-pid and
+per-tgid data. It is versioned and can be extended by each accounting subsystem
+that is added to the kernel. The fields and their semantics are defined in the
+taskstats.h file.
+
+The data exchanged between user and kernel space is a netlink message belonging
+to the NETLINK_GENERIC family and using the netlink attributes interface.
+The messages are in the format
+
+ +----------+- - -+-------------+-------------------+
+ | nlmsghdr | Pad | genlmsghdr | taskstats payload |
+ +----------+- - -+-------------+-------------------+
+
+
+The taskstats payload is one of the following three kinds:
+
+1. Commands: Sent from user to kernel. The payload is one attribute, of type
+TASKSTATS_CMD_ATTR_PID/TGID, containing a u32 pid or tgid in the attribute
+payload. The pid/tgid denotes the task/process for which userspace wants
+statistics.
+
+2. Response for a command: sent from the kernel in response to a userspace
+command. The payload is a series of three attributes of type:
+
+a) TASKSTATS_TYPE_AGGR_PID/TGID : attribute containing no payload but indicates
+a pid/tgid will be followed by some stats.
+
+b) TASKSTATS_TYPE_PID/TGID: attribute whose payload is the pid/tgid whose stats
+is being returned.
+
+c) TASKSTATS_TYPE_STATS: attribute with a struct taskstsats as payload. The
+same structure is used for both per-pid and per-tgid stats.
+
+3. New message sent by kernel whenever a task exits. The payload consists of a
+ series of attributes of the following type:
+
+a) TASKSTATS_TYPE_AGGR_PID: indicates next two attributes will be pid+stats
+b) TASKSTATS_TYPE_PID: contains exiting task's pid
+c) TASKSTATS_TYPE_STATS: contains the exiting task's per-pid stats
+d) TASKSTATS_TYPE_AGGR_TGID: indicates next two attributes will be tgid+stats
+e) TASKSTATS_TYPE_TGID: contains tgid of process to which task belongs
+f) TASKSTATS_TYPE_STATS: contains the per-tgid stats for exiting task's process
+
+
+per-tgid stats
+--------------
+
+Taskstats provides per-process stats, in addition to per-task stats, since
+resource management is often done at a process granularity and aggregating task
+stats in userspace alone is inefficient and potentially inaccurate (due to lack
+of atomicity).
+
+However, maintaining per-process, in addition to per-task stats, within the
+kernel has space and time overheads. Hence the taskstats implementation
+dynamically sums up the per-task stats for each task belonging to a process
+whenever per-process stats are needed.
+
+Not maintaining per-tgid stats creates a problem when userspace is interested
+in getting these stats when the process dies i.e. the last thread of
+a process exits. It isn't possible to simply return some aggregated per-process
+statistic from the kernel.
+
+The approach taken by taskstats is to return the per-tgid stats *each* time
+a task exits, in addition to the per-pid stats for that task. Userspace can
+maintain task<->process mappings and use them to maintain the per-process stats
+in userspace, updating the aggregate appropriately as the tasks of a process
+exit.
+
+Extending taskstats
+-------------------
+
+There are two ways to extend the taskstats interface to export more
+per-task/process stats as patches to collect them get added to the kernel
+in future:
+
+1. Adding more fields to the end of the existing struct taskstats. Backward
+ compatibility is ensured by the version number within the
+ structure. Userspace will use only the fields of the struct that correspond
+ to the version its using.
+
+2. Defining separate statistic structs and using the netlink attributes
+ interface to return them. Since userspace processes each netlink attribute
+ independently, it can always ignore attributes whose type it does not
+ understand (because it is using an older version of the interface).
+
+
+Choosing between 1. and 2. is a matter of trading off flexibility and
+overhead. If only a few fields need to be added, then 1. is the preferable
+path since the kernel and userspace don't need to incur the overhead of
+processing new netlink attributes. But if the new fields expand the existing
+struct too much, requiring disparate userspace accounting utilities to
+unnecessarily receive large structures whose fields are of no interest, then
+extending the attributes structure would be worthwhile.

+Delay accounting
+----------------
+
+Tasks encounter delays in execution when they wait
+for some kernel resource to become available e.g. a
+runnable task may wait for a free CPU to run on.
+
+The per-task delay accounting functionality measures
+the delays experienced by a task while
+
+a) waiting for a CPU (while being runnable)
+b) completion of synchronous block I/O initiated by the task
+c) swapping in pages
+
+and makes these statistics available to userspace through
+the taskstats interface.
+
+Such delays provide feedback for setting a task's cpu priority,
+io priority and rss limit values appropriately. Long delays for
+important tasks could be a trigger for raising its corresponding priority.
+
+The functionality, through its use of the taskstats interface, also provides
+delay statistics aggregated for all tasks (or threads) belonging to a
+thread group (corresponding to a traditional Unix process). This is a commonly
+needed aggregation that is more efficiently done by the kernel.
+
+Userspace utilities, particularly resource management applications, can also
+aggregate delay statistics into arbitrary groups. To enable this, delay
+statistics of a task are available both during its lifetime as well as on its
+exit, ensuring continuous and complete monitoring can be done.
+
+
+Interface
+---------
+
+Delay accounting uses the taskstats interface which is described
+in detail in a separate document in this directory. Taskstats returns a
+generic data structure to userspace corresponding to per-pid and per-tgid
+statistics. The delay accounting functionality populates specific fields of
+this structure. See
+ include/linux/taskstats.h
+for a description of the fields pertaining to delay accounting.
+It will generally be in the form of counters returning the cumulative
+delay seen for cpu, sync block I/O, swapin etc.
+
+Taking the difference of two successive readings of a given
+counter (say cpu_delay_total) for a task will give the delay
+experienced by the task waiting for the corresponding resource
+in that interval.
+
+When a task exits, records containing the per-task and per-process statistics
+are sent to userspace without requiring a command. More details are given in
+the taskstats interface description.
+
+The getdelays.c userspace utility in this directory allows simple commands to
+be run and the corresponding delay statistics to be displayed. It also serves
+as an example of using the taskstats interface.
+
+Usage
+-----
+
+Compile the kernel with
+ CONFIG_TASK_DELAY_ACCT=y
+ CONFIG_TASKSTATS=y
+
+Enable the accounting at boot time by adding
+the following to the kernel boot options
+ delayacct
+
+and after the system has booted up, use a utility
+similar to getdelays.c to access the delays
+seen by a given task or a task group (tgid).
+The utility also allows a given command to be
+executed and the corresponding delays to be
+seen.
+
+General format of the getdelays command
+
+getdelays [-t tgid] [-p pid] [-c cmd...]
+
+
+Get delays, since system boot, for pid 10
+# ./getdelays -p 10
+(output similar to next case)
+
+Get sum of delays, since system boot, for all pids with tgid 5
+# ./getdelays -t 5
+
+
+CPU count real total virtual total delay total
+ 7876 92005750 100000000 24001500
+IO count delay total
+ 0 0
+MEM count delay total
+ 0 0
+
+Get delays seen in executing a given simple command
+# ./getdelays -c ls /
+

Subject: [PATCH 0613/1026] [PATCH] delay accounting taskstats interface send
tgid once
Send per-tgid data only once during exit of a thread group instead of once
with each member thread exit.
Currently, when a thread exits, besides its per-tid data, the per-tgid data
of its thread group is also sent out, if its thread group is non-empty.
The per-tgid data sent consists of the sum of per-tid stats for all
*remaining* threads of the thread group.
This patch modifies this sending in two ways:
- the per-tgid data is sent only when the last thread of a thread group
exits. This cuts down heavily on the overhead of sending/receiving
per-tgid data, especially when other exploiters of the taskstats
interface aren't interested in per-tgid stats
- the semantics of the per-tgid data sent are changed. Instead of being
the sum of per-tid data for remaining threads, the value now sent is the
true total accumalated statistics for all threads that are/were part of
the thread group.
The patch also addresses a minor issue where failure of one accounting
subsystem to fill in the taskstats structure was causing the send of
taskstats to not be sent at all.
The patch has been tested for stability and run cerberus for over 4 hours
on an SMP.

Subject: [PATCH 0615/1026] [PATCH] per-task delay accounting: avoid send
without listeners
Don't send taskstats (per-pid or per-tgid) on thread exit when no one is
listening for such data.
Currently the taskstats interface allocates a structure, fills it in and
calls netlink to send out per-pid and per-tgid stats regardless of whether
a userspace listener for the data exists (netlink layer would check for
that and avoid the multicast).
As a result of this patch, the check for the no-listener case is performed
early, avoiding the redundant allocation and filling up of the taskstats
structures.

Subject: [PATCH 0616/1026] [PATCH] per-task delay accounting taskstats
interface: control exit data through cpumasks
On systems with a large number of cpus, with even a modest rate of tasks
exiting per cpu, the volume of taskstats data sent on thread exit can
overflow a userspace listener's buffers.
One approach to avoiding overflow is to allow listeners to get data for a
limited and specific set of cpus. By scaling the number of listeners
and/or the cpus they monitor, userspace can handle the statistical data
overload more gracefully.
In this patch, each listener registers to listen to a specific set of cpus
by specifying a cpumask. The interest is recorded per-cpu. When a task
exits on a cpu, its taskstats data is unicast to each listener interested
in that cpu.
Thanks to Andrew Morton for pointing out the various scalability and
general concerns of previous attempts and for suggesting this design.

Subject: [PATCH 0617/1026] [PATCH] Remove down_write() from taskstats code
invoked on the exit() path
In send_cpu_listeners(), which is called on the exit path, a down_write()
was protecting operations like skb_clone() and genlmsg_unicast() that do
GFP_KERNEL allocations. If the oom-killer decides to kill tasks to satisfy
the allocations,the exit of those tasks could block on the same semphore.
The down_write() was only needed to allow removal of invalid listeners from
the listener list. The patch converts the down_write to a down_read and
defers the removal to a separate critical region. This ensures that even
if the oom-killer is called, no other task's exit is blocked as it can
still acquire another down_read.
Thanks to Andrew Morton & Herbert Xu for pointing out the oom related
pitfalls, and to Chandra Seetharaman for suggesting this fix instead of
using something more complex like RCU.

Subject: [PATCH 0619/1026] [PATCH] remove set_wmb - arch removal
set_wmb should not be used in the kernel because it just confuses the
code more and has no benefit. Since it is not currently used in the
kernel this patch removes it so that new code does not include it.
All archs define set_wmb(var, value) to do { var = value; wmb(); }
while(0) except ia64 and sparc which use a mb() instead. But this is
still moot since it is not used anyway.
Hasn't been tested on any archs but x86 and x86_64 (and only compiled
tested)

Subject: [PATCH 0622/1026] Don't allow chmod() on the /proc/<pid>/ files
This just turns off chmod() on the /proc/<pid>/ files, since there is no
good reason to allow it, and had we disallowed it originally, the nasty
/proc race exploit wouldn't have been possible.
The other patches already fixed the problem chmod() could cause, so this
is really just some final mop-up..
This particular version is based off a patch by Eugene and Marcel which
had much better naming than my original equivalent one.

Some -mm-only material leaked into a patch destined for mainline, and I didn't

This was the replacement of system_utsname with utsname() that's required by
the uts namespace patch. This patch reverts those changes (which are correct
in -mm) so that mainline UML builds again.

host_set->private_data. This change allows more host_set private
fields to be added.

Subject: [PATCH 0627/1026] [libata] ata_piix: Consolidate PCS register writing
Prior to this patch, the driver would do this for each port:
read 8-bit PCS
write 8-bit PCS
read 8-bit PCS
write 8-bit PCS
In the field, flaky behavior has been observed related to this register.
In particular, these overzealous register writes can cause misdetection
problems.
Update to do the following once (not once per port) at boot:
read 16-bit PCS
if needs changing,
write 16-bit PCS
And thereafter, we only perform a 'read 16-bit PCS' per port.
This should eliminate all PCS writes in many cases, and be more friendly
in the cases where we do need to enable ports.

The NAPI poll routine gets called back to keep going, but since no IRQ bits
are set it doesn't make progress.
Increase version, since this is serious enough problem that I want to be
able to tell new from old problems.

Subject: [PATCH 0638/1026] [PATCH] spidernet: rework tx queue handling
With this patch TX queue descriptors are not chained per default any more.
The pointer to next descriptor is set only when next descriptor is prepaired
for transfer. Also the mechanism of checking wether Spider is ready has been
changed: it checks not for CARDOWNED flag in status of previous descriptor
but for a TXDMAENABLED flag in Spider's register.

Subject: [PATCH 0641/1026] [PATCH] libata: fix autopsy ehc->i.action and
ehc->i.dev handling
Commit 0662c58b3265f52f708a6d59476bc7862b01f9c0 updated
ata_eh_autopsy() to OR determined action to ehc->i.action to preserve
action mask set directly into ehc->i.action by nested functions. This
broke action mask clearing on SENSE_VALID case causing revalidation
and EH complete message on successful ATAPI CC.
This patch removes two local variables - action and failed_dev - which
cache ehc->i.action and ehc->i.dev respectively, and make the function
directly modify ehc->i.* fields to remove aliasing issues.

Subject: [PATCH 0642/1026] [PATCH] libata: fix eh_skip_recovery condition
* (ata_dev_absent() || ata_dev_ready()) test doesn't indicate
SUSPENDED state properly. Fix it.
* Link resuming resets shouldn't be skipped. Don't skip recovery on
EHI_RESUME_LINK. This doesn't matter for host ports as EHI_RESUME
always coincides with EHI_HOTPLUGGED which makes attached disabled
devices vacant. However, PMP reset causes non-hotplug link-resuming
resets which shouldn't be skipped.

Subject: [PATCH 0643/1026] [PATCH] libata: improve EH action and EHI flag
handling
Update ata_eh_about_to_do() and ata_eh_done() to improve EH action and
EHI flag handling.
* There are two types of EHI flags - one which expires on successful
EH and the other which expires on a successful reset. Make this
distinction clear.
* Unlike other EH actions, reset actions are represented by two EH
action masks and a EHI modifier. Implement correct about_to_do/done
semantics for resets. That is, prior to reset, related EH info is
sucked in from ehi and cleared, and after reset is complete, related
EH info in ehc is cleared.
These changes improve consistency and remove unnecessary EH actions
caused by stale EH action masks and EHI flags.

Subject: [PATCH 0644/1026] via-velocity: fix speed and link status reported by
ethtool
The via-velocity driver reports incorrect speed and link detected status
as viewed by ethtool (and probably other tools). This patch fixes those
incorrect reports and prettifies a long line.

Subject: [PATCH 0645/1026] [SPARC64]: Fix more of_device layer IRQ bugs, and
correct PROMREG_MAX.
Sabre and Psycho PCI controllers can have partial interrupt-map
properties, meaning that on-board devices don't match up to any
entries. Instead, they are fully specified from the beginning and
we should pass them directly to the IRQ translator as-is.
Also, fill in the necessary translator slots for the "graphics"
and "expansion UPA" interrupts on Sabre, Psycho, and SYSIO SBUS.
Increase PROMREG_MAX to 24, as seen on SUNW,ffb devices.
Finally, prevent accidentally writing past the end of the of_device
struct resource[] and irqs[] arrays. Spit out a log message when
we ignore some entries because there are too many of them.

Subject: [PATCH 0648/1026] [SERIAL] sunsab: Get line numbers and table sizing
correct.
Table sizing code should look for "se" not "su" nodes.
The chip at the lower address should get the first index.

Subject: [PATCH 0649/1026] [SPARC]: Fix property name acquisition in prom.c
On sparc32 the prom_{first,next}prop() interfaces work
a little differently. The buffer argument is ignored on
sparc32 and the firmware just returns a raw pointer to
the property name.

Subject: [PATCH 0658/1026] [SERIAL] sunzilog: Fix instance enumeration.
Just do a linear enumeration so that we handle sun4d systems
correctly. As a consequence, eliminate the hard coded keyboard and
mouse channel line values, use the CONS_{KEYB,MS} flags instead.
Also, report the keyboard/mouse Zilog channels just like the uart ones
do.

Subject: [PATCH 0665/1026] [PKT_SCHED] netem: Fix slab corruption with netem
(2nd try)
CONFIG_DEBUG_SLAB found the following bug:
netem_enqueue() in sch_netem.c gets a pointer inside a slab object:
struct netem_skb_cb *cb = (struct netem_skb_cb *)skb->cb;
But then, the slab object may be freed:
skb = skb_unshare(skb, GFP_ATOMIC)
cb is still pointing inside the freed skb, so here is a patch to
initialize cb later, and make it clear that initializing it sooner
is a bad idea.
[From Stephen Hemminger: leave cb unitialized in order to let gcc
complain in case of use before initialization]

Subject: [PATCH 0669/1026] [SCTP]: Set chunk->data_accepted only if we are
going to accept it.
Currently there is a code path in sctp_eat_data() where it is possible
to set this flag even when we are dropping this chunk.

Subject: [PATCH 0671/1026] [I/OAT]: net/core/user_dma.c should #include
<net/netdma.h>
Every file should #include the headers containing the prototypes for
its global functions.
Especially in cases like this one where gcc can tell us through a
compile error that the prototype was wrong...

Subject: [PATCH 0673/1026] [IrDA]: Use alloc_skb() in IrDA TX path
As pointed out by Christoph Hellwig, dev_alloc_skb() is not intended to be
used for allocating TX sk_buff. The IrDA stack was exclusively calling
dev_alloc_skb() on the TX path, and this patch fixes that.

routes
Routing realms exist per nexthop, but are only returned to userspace
for the first nexthop. This is due to the fact that iproute2 only
allows to set the realm for the first nexthop and the kernel refuses
multipath routes where only a single realm is present.
Dump all realms for multipath routes to enable iproute to correctly
display them.

Subject: [PATCH 0683/1026] cpu hotplug: simplify and hopefully fix locking
The CPU hotplug locking was quite messy, with a recursive lock to
handle the fact that both the actual up/down sequence wanted to
protect itself from being re-entered, but the callbacks that it
called also tended to want to protect themselves from CPU events.
This splits the lock into two (one to serialize the whole hotplug
sequence, the other to protect against the CPU present bitmaps
changing). The latter still allows recursive usage because some
subsystems (ondemand policy for cpufreq at least) had already gotten
too used to the lax locking, but the locking mistakes are hopefully
now less fundamental, and we now warn about recursive lock usage
when we see it, in the hope that it can be fixed.

Subject: [PATCH 0684/1026] [PATCH] Cpuset: fix ABBA deadlock with cpu hotplug
lock
Fix ABBA deadlock between lock_cpu_hotplug() and the cpuset
callback_mutex lock.
It only happens on cpu_exclusive cpusets, due to the dynamic
sched domain code trying to take the cpu hotplug lock inside
the cpuset callback_mutex lock.
This bug has apparently been here for several months, but didn't
get hit until the right customer load on a large system.
This fix appears right from inspection, but it will take a few
more days running it on that customers workload to be confident
we nailed it. We don't have any other reproducible test case.
The cpu_hotplug_lock() tends to cover large runs of code.
The other places that hold both that lock and the cpuset callback
mutex lock always nest the cpuset lock inside the hotplug lock.
This place tries to do the reverse, risking an ABBA deadlock.
This is in the cpuset_rmdir() code, where we:
* take the callback_mutex lock
* mark the cpuset CS_REMOVED
* call update_cpu_domains for cpu_exclusive cpusets
* in that call, take the cpu_hotplug lock if the
cpuset is marked for removal.
Thanks to Jack Steiner for identifying this deadlock.
The fix is to tear down the dynamic sched domain before we grab
the cpuset callback_mutex lock. This way, the two locks are
serialized, with the hotplug lock taken and released before
trying for the cpuset lock.
I suspect that this bug was introduced when I changed the
cpuset locking from one lock to two. The dynamic sched domain
dependency on cpu_exclusive cpusets and its hotplug hooks were
added to this code earlier, when cpusets had only a single lock.
It may well have been fine then.

Subject: [PATCH 0690/1026] IB/ipath: Fix ib_ipath driver to work with SRP
I am still working on a proposal to remove the phys_to_virt() calls
in the ib_ipath driver. In the mean time, this patch allows SRP
to work by fixing the R_Key check and conversion from IB address
to kernel virtual address. It also returns the correct page size
for FMRs.

Subject: [PATCH 0691/1026] IB/ipath: ipath_skip_sge() can break if num_sge > 1
ipath_skip_sge() doesn't exactly duplicate the side effects of
ipath_copy_sge() if num_sge > 1 since it doesn't decrement ss->num_sge.
This could result in the sg_list being accessed out of bounds.
Since ipath_skip_sge() is almost always called with num_sge == 1,
the original "optimization" is almost never used.

Validate MADs sent by userspace clients for spec compliance with
C13-18.1.1 (prevent duplicate requests and responses sent on the

of duplicate packets.

I went to alter the default sysctl and it didn't take for new sockets.
Below patch fixes this.
I think the default is too low but it is what the DCCP spec specifies.
As a side effect of this my rx speed using iperf goes from about 2.8 Mbits/sec
to 3.5. This is still far too slow but it is a step in the right direction.
Compile tested only for IPv6 but not particularly complex change.

Subject: [PATCH 0697/1026] [PKT_SCHED]: Fix regression in PSCHED_TADD{,2}.
In PSCHED_TADD and PSCHED_TADD2, if delta is less than tv.tv_usec (so,
less than USEC_PER_SEC too) then tv_res will be smaller than tv. The
affectation "(tv_res).tv_usec = __delta;" is wrong. The fix is to
revert to the original code before
4ee303dfeac6451b402e3d8512723d3a0f861857 and change the 'if' in
'while'.

Subject: [PATCH 0698/1026] [Bluetooth] Correct RFCOMM channel MTU for broken
implementations
Some Bluetooth RFCOMM implementations try to negotiate a bigger channel
MTU than we can support for a particular session. The maximum MTU for
a RFCOMM session is limited through the L2CAP layer. So if the other
side proposes a channel MTU that is bigger than the underlying L2CAP
MTU, we should reduce it to the L2CAP MTU of the session minus five
bytes for the RFCOMM headers.

It doesn't compile, and it's dubious in several regards:
1) is enabled by non-Kconfig controlled CONFIG_* value
(noted by Randy Dunlap)
2) XFRM6_TUNNEL_SPI_MAGIC is defined after it's first use
3) the debugging messages print object pointer addresses
which have no meaning without context
So let's just get rid of it.

When the queue of the underlying device is stopped at initialization time
or the device is marked "not present", the state will be propagated to the
vlan device and never change. Based on an analysis by Patrick McHardy.

Subject: [PATCH 0715/1026] [NETFILTER]: xt_pkttype: fix mismatches on locally
generated packets
Locally generated broadcast and multicast packets have pkttype set to
PACKET_LOOPBACK instead of PACKET_BROADCAST or PACKET_MULTICAST. This
causes the pkttype match to fail to match packets of either type.
The below patch remedies this by using the daddr as a hint as to
broadcast|multicast. While not pretty, this seems like the only way
to solve the problem short of just noting this as a limitation of the
match.
This resolves netfilter bugzilla #484

+What: Bridge netfilter deferred IPv4/IPv6 output hook calling
+When: January 2007
+Why: The deferred output hooks are a layering violation causing unusual
+ and broken behaviour on bridge devices. Examples of things they
+ break include QoS classifation using the MARK or CLASSIFY targets,
+ the IPsec policy match and connection tracking with VLANs on a
+ bridge. Their only use is to enable bridge output port filtering
+ within iptables with the physdev match, which can also be done by
+ combining iptables and ebtables using netfilter marks. Until it
+ will get removed the hook deferral is disabled by default and is
+ only enabled when needed.

Subject: [PATCH 0724/1026] [POWERPC] Workaround Pegasos incorrect ISA "ranges"
The Pegasos firmware doesn't create a valid "ranges" property for the
ISA bridge, thus causing translation of ISA addresses and IO ports to
fail. This fixes it, thus re-enabling proper early serial console to
work on Pegasos.

Subject: [PATCH 0726/1026] [POWERPC] Fix non-MPIC CHRPs with CONFIG_SMP set
Pseudo-CHRP machines like Pegasos without an MPIC would crash at boot if
CONFIG_SMP was set because the "smp_ops" pointer was set to MPIC related
ops unconditionally. This patch makes it NULL on machines that don't
support SMP and provides proper default behaviour in the callers when
smp_ops is NULL.

Subject: [PATCH 0728/1026] [POWERPC] Fix legacy_serial.c error handling on 32
bits
The code in legacy_serial.c wouldn't properly compare OF translation
results against OF_BAD_ADDR as it's using a phys_addr_t which is 32
bits on some 32-bit powerpc platforms. This fixes it by always using
a u64 which is what is returned by the OF parsing routines. It also
makes translation failure harmless for ISA serial ports. If they
can't translate, we can't use the UART early, but we can still let the
8250 driver use it later on by using IO port accessors.

Subject: [PATCH 0729/1026] [POWERPC] More offb/bootx fixes
There were still some issues with offb when BootX doesn't provide a
proper display node, this fixes them. This also re-instates the
palette hacks that were disabled a couple of kernel versions ago when
I converted to the new OF parsing, and shuffles some functions around
to avoid prototypes.

Subject: [PATCH 0730/1026] [POWERPC] Fix mem= handling when the memory limit
is > RMO size
There's a bug in my cleaned up mem= handling, if the memory limit is
larger than the RMO size we'll erroneously enlarge the RMO size.
Fix is to only change the RMO size if the memory limit is less than
the current RMO value.

IP multicast route code was reusing an skb which causes use after free
and double free.
From: Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>
Note, it is real skb_clone(), not alloc_skb(). Equeued skb contains
the whole half-prepared netlink message plus room for the rest.
It could be also skb_copy(), if we want to be puristic about mangling
cloned data, but original copy is really not going to be used.

Subject: [PATCH 0735/1026] [IPV4/IPV6]: Setting 0 for unused port field in RAW
IP recvmsg().
From: Tetsuo Handa from-linux-kernel@i-love.sakura.ne.jp
The recvmsg() for raw socket seems to return random u16 value
from the kernel stack memory since port field is not initialized.
But I'm not sure this patch is correct.
Does raw socket return any information stored in port field?
[ BSD defines RAW IP recvmsg to return a sin_port value of zero.
This is described in Steven's TCP/IP Illustrated Volume 2 on
page 1055, which is discussing the BSD rip_input() implementation. ]

Subject: [PATCH 0736/1026] [PATCH] Reorganize the cpufreq cpu hotplug locking
to not be totally bizare
The patch below moves the cpu hotplugging higher up in the cpufreq
layering; this is needed to avoid recursive taking of the cpu hotplug
lock and to otherwise detangle the mess.
The new rules are:
1. you must do lock_cpu_hotplug() around the following functions:
__cpufreq_driver_target
__cpufreq_governor (for CPUFREQ_GOV_LIMITS operation only)
__cpufreq_set_policy
2. governer methods (.governer) must NOT take the lock_cpu_hotplug()
lock in any way; they are called with the lock taken already
3. if your governer spawns a thread that does things, like calling
__cpufreq_driver_target, your thread must honor rule #1.
4. the policy lock and other cpufreq internal locks nest within
the lock_cpu_hotplug() lock.
I'm not entirely happy about how the __cpufreq_governor rule ended up
(conditional locking rule depending on the argument) but basically all
callers pass this as a constant so it's not too horrible.
The patch also removes the cpufreq_governor() function since during the
locking audit it turned out to be entirely unused (so no need to fix it)
The patch works on my testbox, but it could use more testing
(otoh... it can't be much worse than the current code)

Subject: [PATCH 0737/1026] [PATCH] fix compile regression for a few scsi
drivers
This fixes three drivers to compile again after my patch that removes
the data_cmnd member from struct scsi_cmnd.
The fas216 change is trivial, it should have been using ->cmnd all the
time.
NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing
something odd, it should only have looked at ->cmnd before not the saved
copy that is kept for the error handlers sake. Note that it really
should deal with the sync setting themselves but use the generic domain
validation code that get this right - but that's for later let's push
this simple compile fix for now.
And sorry for the late fix for this, I have been busy with OLS and
associated activities last week.

Subject: [PATCH 0741/1026] [S390] permanent subchannel busy conditions may
cause I/O stall
In special conditions where a subchannel rejects the HALT I/O-
instruction with a busy indication (cc 2), I/O may stall.
I/O request termination logic retries HALT I/O indefinitely
because it expects HALT I/O to alter the subchannel status which
is not true when cc 2 is returned.
In case of a busy indication, try CLEAR I/O instruction immediately.

Johann Uhrmann reported a bcm43xx crash and Michael Buesch tracked
it down to a problem with the new shared key auth code (recursive
calls into the driver)
This patch (effectively Michael's patch with a couple of small
modifications) solves the problem by sending the authentication
challenge response frame from a workqueue entry.
I also removed a lone \n from the bcm43xx messages relating to
authentication mode - this small change was previously discussed but
not patched in.

When determining whether there's a key to set or not, orinoco should be
looking at the key length, not the key data. Otherwise confusion reigns
when trying to set TX key only, passing in zero-length key, but non-NULL
pointer. Key length takes precedence over non-NULL key data.

Subject: [PATCH 0750/1026] [POWERPC] Xserve G5 thermal control fixes
The thermal control for the Xserve G5s had a few issues. For one, the
way to program the RPM fans speeds into the FCU is different between it
and the desktop models, which I didn't figure out until recently, and it
was missing a control loop for the slots fan, running it too fast. Both
of those problems were causing the machine to be much more noisy than
necessary. This patch also changes the fixed value of the slots fan for
desktop G5s to 40% instead of 50%. It seems to still have a pretty good
airflow that way and is much less noisy.

Subject: [PATCH 0751/1026] [POWERPC] Add cpufreq support for Xserve G5
The Xserve G5 are capable of frequency switching like other desktop G5s.
This enables it. It also fix a Kconfig issue which prevented from
building the G5 cpufreq support if CONFIG_PMAC_SMU was not set (the
first version of that driver only worked with SMU based macs, but this
isn't the case anymore).

Subject: [PATCH 0766/1026] [POWERPC] force 64bit mode in fwnmi handlers to
workaround firmware bugs
The firmware of POWER4 and JS20 systems does not switch the cpu to 64bit
mode when the registered system_reset and machine_check handlers get called.
If a 32bit process runs on that cpu at the time of the event, the cpu
remains in 32bit mode. xmon and kdump can not deal with it, the result is
an error like 'Bad kernel stack pointer fff2aad0 at 3200'.
xmon just loses some register info, but booting the kdump kernel usually fails.
Both handlers are not hot paths. Duplicate the EXCEPTION_PROLOG_PSERIES macro
and add two instructions to switch to 64bit:
li r11,5;
rldimi r10,r11,61,0;

Subject: [PATCH 0768/1026] [PATCH] i386/x86-64: Add user_mode checks to
profile_pc for oprofile
Fixes a obscure user space triggerable crash during oprofiling.
Oprofile calls profile_pc from NMIs even when user_mode(regs) is not true and
the program counter is inside the kernel lock section. This opens
a race - when a user program jumps to a kernel lock address and
a NMI happens before the illegal page fault exception is raised
and the program has a unmapped esp or ebp then the kernel could
oops. NMIs have a higher priority than exceptions so that could
happen.
Add user_mode checks to i386/x86-64 profile_pc to prevent that.

handler
When int 0x80 is called from long mode r8-r11 would leak out of the
kernel (or rather they would be filled with some values from
the kernel stack). I don't think it's a security issue because
the values come from the fixed stack frame which should be near
always user registers from a previous interrupt.
Still better fix it.
Longer term the register save macros need to be cleaned up
to avoid such mistakes in the future.
Original analysis from Richard Brunner, fix by me.

Subject: [PATCH 0770/1026] [PATCH] x86_64: Enlarge debug stack for nested
kprobes
In x86_64 platform, INT1 and INT3 trap stack is IST stack called DEBUG_STACK,
when INT1/INT3 trap happens, system will switch to DEBUG_STACK by hardware.
Current DEBUG_STACK size is 4K, when int1/int3 trap happens, kernel will
minus current DEBUG_STACK IST value by 4k. But if int3/int1 trap is nested,
it will destroy other vector's IST stack. This patch modifies this, it sets
DEBUG_STACK size as 8K and allows two level of nested int1/int3 trap.
Kprobe DEBUG_STACK may be nested, because kprobe handler may be probed
by other kprobes.
Thanks jbeulich for pointing out error in the first patch.
[AK: nested kprobes are pretty dubious. Hopefully one nest
will be enough. This will cost 8K per CPU (4K more than before)]

This currently often happens with __down. Should fix this by
adding proper dwarf2 annotation to all inline assembly. However
until that's done we need a quick fix for 2.6.18 to avoid
incomplete backtraces.
So when this happens dump the rest of the stack with the old unwinder
instead of silently not dumping it. There was already a optional
"both" mode that dumped both, but that was too ugly.
I also clarified the headers for the different backtraces a bit.
Also add a clear error message for missing dwarf2
annotation that people can work on.
And I removed a dead variable left over from Ingo's changes.

Subject: [PATCH 0775/1026] [PATCH] pi-futex: robust-futex exit
Fix robust PI-futexes to be properly unlocked on unexpected exit.
For this to work the kernel has to know whether a futex is a PI or a
non-PI one, because the semantics are different. Since the space in
relevant glibc data structures is extremely scarce, the best solution is
to encode the 'PI' information in bit 0 of the robust list pointer.
Existing (non-PI) glibc robust futexes have this bit always zero, so the
ABI is kept. New glibc with PI-robust-futexes will set this bit.

Subject: [PATCH 0778/1026] [ARM] 3736/1: xscale: don't mis-report 80219 as an
iop32x
Patch from Lennert Buytenhek
The IOP 80219 xscale CPU is a stripped down version of the IOP32x.
But the fact that the 80219 and IOP32x are very similar doesn't mean
that they need to share a cpu table entry. It's also somewhat confusing
for the end user to see the 80219 reported as an IOP32x, so this patch
splits the IOP32x cpu table entry to make a separate entry for the
80219.

Subject: [PATCH 0779/1026] [ARM] 3737/1: Export ARM copy/clear_user_page
symbols
Patch from George G. Davis
As reported by various folks on the ARM Linux kernel mailing list,
the video-buf.ko driver has undefined references on all ARM machines
which use it as observed during `make modules`:
Warning: "v4wb_clear_user_page" [drivers/media/video/video-buf.ko] undefined!
Similar warnings exist for all ARM machines which use this driver.
So this change adds the missing EXPORT_SYMBOLs to allow using this
driver as a module.

Some cards have multiple possible addresses for their PLLs, with no other
way to tell if a PLL is present or not apart from probing to see if an i2c
device is present. This adds a quick check to see if an i2c device is
present at the given i2c address.

Subject: [PATCH 0782/1026] V4L/DVB (4292): Fix DISEQC regression
The changes to add frontend reinitialisation moved the position where the
init() op is called into the frontend thread. Unfortunately, since DISEQC
operations do not use the frontend thread, this meant that DISEQC could be
called against an uninitalised frontend, leading to all sorts of trouble.
Patch fixes this by reinstating the original fronted intialisation call.

This patch just sets the option noninterlaced to 1 by default since
it has no known disadvantages. It is still possibe to get the old
behaviour by setting noninterlaced=0.

Subject: [PATCH 0791/1026] V4L/DVB (4314): Set the Auxiliary Byte when tuning
LG H06xF in analog mode
With the LG H06xF tuners, an auxiliary byte must be sent after the
standard four-byte i2c sequence. The code that does this is currently in
the wrong place, causing random bytes to be written to the tuner over
i2c in the set_type function.
This patch moves this code from set_type to default_set_tv_freq.

Check __must_check warnings for class_device_register and class_device_create_file
video_device_create_file was declared as a void, but instead should
return the int value of class_device_create_file.
Move the check from bttv-driver.c into v4l2-dev.h, because all other
callers of video_device_create_file must also be checked.
Replace the call to class_device_create_file in videodev.c with
video_device_create_file, as defined in v4l2-dev.h, so that the
return value of class_device_create_file will be checked.
Check the return value of class_device_register in videodev.c and
pvrusb2-sysfs.c

Subject: [PATCH 0793/1026] V4L/DVB (4323):
[budget/budget-av/budget-ci/budget-patch drivers] fixed DMA start/stop code
Fix bug reported by Andrew de Quincey:
After cold boot the saa7146 DMA did not start if the demuxer was opened
before the frontend has locked to the signal.
DMA transfers will be started now if (and only if)
the frontend is locked and data should be sent to the demuxer.

Supplying a NULL i2c adapter to dvb_pll_attach is allowed, for example with
mt352 demods. However, the pll i2c probe will segfault because it does not
check for this.

Trent Piepho pointed out that the pll test i2c transmission is slightly
wrong; it was transmitting a zero length message, and then reading from the
PLL. This was wrong; it should only be transmitting a single read i2c message.

Subject: [PATCH 0797/1026] V4L/DVB (4341): VIDIOCSMICROCODE were missing on
compat_ioctl32
video_code size is 24 on i386 and 32 on x86_64, so a proper handling is needed
on compat_ioctl32 to fix it.
This code should be tested, since just *a few* boards use this ioctl.

Subject: [PATCH 0798/1026] V4L/DVB (4342): Fix ext_controls align on 64 bit
architectures
u64 is aligned as 128bits on x86_64 architetures, requiring an special
handling to ioctls that depends on v4l2_ext_control.
Let's fix this before ext controls go to kernel mainstream to avoid one
more compat32 stuff.

Subject: [PATCH 0801/1026] V4L/DVB (4365): OVERLAY flag were enabled by
mistake
A patch from Aug, 17 activated by mistake OVERLAY flag on cx88-video,
together with several cx88-blackbird cleanups. This makes the cx88 driver
to report:
/dev/video0 [v4l2]: ioctl VIDIOC_G_FBUF: Invalid argument
instead of:
/dev/video0 [v4l2]: no overlay support

Subject: [PATCH 0802/1026] V4L/DVB (4367): Videodev: Handle class_device
related errors
Add proper error checking and roll-back for failure of
class_device_create_file() in videodev.c. Print error messages and
unroll partially created sysfs entries.
Also, failure of class_device_register() in video_register_device() is
handled correctly. It was failing to de-allocate the minor number. This
must be done in video_register_device(), since the caller has no way of
knowing if failure occurred before or after the class device was
registered.
Also added an error message if video_register_device() is called with
an unknown type, which should never happen.

and handle errors
Revert bttv-driver.c from video_device_create_file() to use
class_device_create_file() again. video_device_create_file() is only
available when V4L1 is on.
Proper error checking is added for failure of class_device_create_file().
Will print error message and unroll partially created sysfs entries.

A previous patch changed VBI_OFFSET to match what the datasheets say it
should be. However, the bt8x8 datasheets are wrong. The old value of
244 is closer to what is actually observed. The real value appears to
not be constant and is different for different chip revisions.

Subject: [PATCH 0810/1026] [PATCH] x86_64: Calgary IOMMU - Multi-Node NULL
pointer dereference fix
Calgary hits a NULL pointer dereference when booting in a multi-chassis
NUMA system. See Redhat bugzilla number 198498, found by Konrad
Rzeszutek (konradr@redhat.com).
There are many issues that had to be resolved to fix this problem.
Firstly when I originally wrote the code to handle NUMA systems, I
had a large misunderstanding that was not corrected until now. That was
that I thought the "number of nodes online" referred to number of
physical systems connected. So that if NUMA was disabled, there
would only be 1 node and it would only show that node's PCI bus.
In reality if NUMA is disabled, the system displays all of the
connected chassis as one node but is only ignorant of the delays
in accessing main memory. Therefore, references to num_online_nodes()
and MAX_NUMNODES are incorrect and need to be set to the maximum
number of nodes that can be accessed (which are 8). I created a
variable, MAX_NUM_CHASSIS, and set it to 8 to fix this.
Secondly, when walking the PCI in detect_calgary, the code only
checked the first "slot" when looking to see if a device is present.
This will work for most cases, but unfortunately it isn't always the
case. In the NUMA MXE drawers, there are USB devices present on the
3rd slot (with slot 1 being empty). So, to work around this, all
slots (up to 8) are scanned to see if there are any devices present.
Lastly, the bus is being enumerated on large systems in a different
way the we originally thought. This throws the ugly logic we had
out the window. To more elegantly handle this, I reorganized the
kva array to be sparse (which removed the need to have any bus number
to kva slot logic in tce.c) and created a secondary space array to
contain the bus number to phb mapping.
With these changes Calgary boots on an x460 with 4 nodes with and
without NUMA enabled.

bug workaround.
And previously there was no way to force swiotlb if there is another IOMMU.
Side effect is that iommu=force won't force swiotlb anymore even if there
isn't another IOMMU.

On the JS21 systems, they have the SPLPAR hypertas set, but are not SMT
capable. So, they are not making the H_CEDE call. This is causing the
hypervisor to have to queue up work for the hdecr, taking an excessive
amount of time in maintenance code, and causing jitter on the box.
Making the H_CEDE call helps alleviate that problem.

Subject: [PATCH 0818/1026] [IA64] Format /proc/pal/*/version_info correctly
/proc/pal/*/version_info is a bit confusing. HP firmware, at least,
reports 07.31 instead of 0.7.31. Also, the comment is out of place;
it's an internal detail about the implementation of ia64_pal_version.
Since the 2.2 revision of the SDM still states that PAL_VERSION can
be called in virtual mode, correct the comment to be more accurate.

Subject: [PATCH 0821/1026] [PATCH] ext3: avoid triggering ext3_error on bad
NFS file handle
The inode number out of an NFS file handle gets passed eventually to
ext3_get_inode_block() without any checking. If ext3_get_inode_block()
allows it to trigger an error, then bad filehandles can have unpleasant
effect - ext3_error() will usually cause a forced read-only remount, or a
panic if `errors=panic' was used.
So remove the call to ext3_error there and put a matching check in
ext3/namei.c where inode numbers are read off storage.

Subject: [PATCH 0822/1026] [PATCH] Process Events: Fix biarch compatibility
issue. use __u64 timestamp
Events sent by Process Events Connector from a 64-bit kernel are not binary
compatible with a 32-bit userspace program because the "timestamp" field
(struct timespec) is not arch independent. This affects the fields that
follow "timestamp" as they will be be off by 8 bytes.
This is a problem for 32-bit userspace programs running with 64-bit kernels
on ppc64, s390, x86-64.. any "biarch" system.
Matt had submitted a different solution to lkml as an RFC earlier. We have
since switched to a solution recommended by Evgeniy Polyakov.
This patch fixes the problem by changing the timestamp to be a __u64, which
stores the number of nanoseconds.
Tested on a x86_64 system with both 32 bit application and 64 bit
application and on a i386 system.

Subject: [PATCH 0824/1026] [PATCH] genirq: {en,dis}able_irq_wake() need
refcounting too
IRQs need refcounting and a state flag to track whether the the IRQ should
be enabled or disabled as a "normal IRQ" source after a series of calls to
{en,dis}able_irq(). For shared IRQs, the IRQ must be enabled so long as at
least one driver needs it active.
Likewise, IRQs need the same support to track whether the IRQ should be
enabled or disabled as a "wakeup event" source after a series of calls to
{en,dis}able_irq_wake(). For shared IRQs, the IRQ must be enabled as a
wakeup source during sleep so long as at least one driver needs it. But
right now they _don't have_ that refcounting ... which means sharing a
wakeup-capable IRQ can't work correctly in some configurations.
This patch adds the refcount and flag mechanisms to set_irq_wake() -- which
is what {en,dis}able_irq_wake() call -- and minimal documentation of what
the irq wake mechanism does.
Drivers relying on the older (broken) "toggle" semantics will trigger a
warning; that'll be a handful of drivers on ARM systems.

Subject: [PATCH 0825/1026] [PATCH] make taskstats sending completely
independent of delay accounting on/off status
Complete the separation of delay accounting and taskstats by ignoring the
return value of delay accounting functions that fill in parts of taskstats
before it is sent out (either in response to a command or as part of a task
exit).
Also make delayacct_add_tsk return silently when delay accounting is turned
off rather than treat it as an error.

Subject: [PATCH 0827/1026] [PATCH] delay accounting: temporarily enable by
default
Enable delay accounting by default so that feature gets coverage testing
without requiring special measures.
Earlier, it was off by default and had to be enabled via a boot time param.
This patch reverses the default behaviour to improve coverage testing. It
can be removed late in the kernel development cycle if its believed users
shouldn't have to incur any cost if they don't want delay accounting. Or
it can be retained forever if the utility of the stats is deemed common
enough to warrant keeping the feature on.

The recent zlib update (commit 4f3865fb57a04db7cca068fed1c15badc064a302)
broke ppc32 zImage decompression as it tries to decompress to address zero
and the updated zlib_inflate checks that strm->next_out isn't a null
pointer.
This little patch fixes it.

Subject: [PATCH 0830/1026] [PATCH] knfsd: Fix stale file handle problem with
subtree_checking.
A recent commit (7fc90ec93a5eb71f4b08403baf5ba7176b3ec6b1) moved the
call to nfsd_setuser out of the 'find a dentry for a filehandle' branch
of fh_verify so that it would always be called.
This had the unfortunately side-effect of moving *after* the call to
decode_fh, so the prober fsuid was not set when nfsd_acceptable was called,
the 'permission' check did the wrong thing.
This patch moves the nfsd_setuser call back where it was, and add as call
in the other branch of the if.

Subject: [PATCH 0835/1026] [PATCH] kprobe-booster: disable in preemptible
kernel
The kprobe-booster's safety check against preemption does not work well
now, because the preemption count has been modified by read_rcu_lock() in
atomic_notifier_call_chain() before we check it. So, I'd like to prevent
boosting kprobe temporarily if the kernel is preemptable.
Now we are searching for the good solution.

Subject: [PATCH 0838/1026] [PATCH] IA64: kprobe invalidate icache of jump
buffer
Kprobe inserts breakpoint instruction in probepoint and then jumps to
instruction slot when breakpoint is hit, the instruction slot icache must
be consistent with dcache. Here is the patch which invalidates instruction
slot icache area.
Without this patch, in some machines there will be fault when executing
instruction slot where icache content is inconsistent with dcache.

When resuming from suspend-to-RAM, the NMI watchdog detects a lockup in
ide_wait_not_busy. Here's a screenshot of the trace taken by a digital

Let's touch the NMI watchdog in ide_wait_not_busy. The system then resumes

Subject: [PATCH 0845/1026] [PATCH] nbd: Abort request on data reception
failure
When reading from nbd device, we need to receive all the data after
receiving reply packet from the server - otherwise such request will never
be ended.
If socket is closed right after accepting reply control packet and in the
middle of waiting for read data, nbd_read_stat() returns NULL and
nbd_end_request() is not called.
This patch fixes it.

Subject: [PATCH 0847/1026] [PATCH] panic_on_oops: remove ssleep()
This patch is part of an effort to unify the panic_on_oops behaviour across
all architectures that implement it.
It was pointed out to me by Andi Kleen that if an oops has occured in
interrupt context, then calling sleep() in the oops path will only cause a
panic, and that it would be really better for it not to be in the path at
all.
This patch removes the ssleep() call and reworks the console message
accordinly. I have a slght concern that the resulting console message is
too long, feedback welcome.
For powerpc it also unifies the 32bit and 64bit behaviour.
Fror x86_64, this patch only updates the console message, as ssleep() is
already not present.

Subject: [PATCH 0848/1026] [PATCH] cpu hotplug: replace __devinit* with
__cpuinit* for cpu notifications
Few of the callback functions and notifier blocks that are associated with cpu
notifications incorrectly have __devinit and __devinitdata. They should be
__cpuinit and __cpuinitdata instead.
It makes no functional difference but wastes text area when CONFIG_HOTPLUG is
enabled and CONFIG_HOTPLUG_CPU is not.
This patch fixes all those instances.

You can fail PREPARE notifiers if something doesn't work to prepare resources.

Subject: [PATCH 0851/1026] [PATCH] fix bad macro param in timer.c
We have
#define INDEX(N) (base->timer_jiffies >> (TVR_BITS + N * TVN_BITS)) & TVN_MASK
and it's used via
list = varray[i + 1]->vec + (INDEX(i + 1));
So, due to underparenthesisation, this INDEX(i+1) is now a ... (TVR_BITS + i
+ 1 * TVN_BITS)) ...
So this bugfix changes behaviour. It worked before by sheer luck:
"If i was anything but 0, it was broken. But this was only used by
s390 and arm. Since it was for the next interrupt, could that next
interrupt be a problem (going into the second cascade)? But it was
probably seldom wrong. That is, this would fail if the next
interrupt was in the second cascade, and was wrapped. Which may
never of happened. Also if it did happen, it would have just missed
the interrupt.
If an interrupt was missed, and no one was there to miss it, was it
really missed :-)"

Subject: [PATCH 0852/1026] [PATCH] fix cond_resched() fix
In cond_resched_lock() it calls __resched_legal() before dropping the spin
lock. __resched_legal() will always finds the preempt_count non-zero and
will prevent the call to __cond_resched().
The attached patch adds a parameter to __resched_legal() with the expected
preempt_count value.

functions
kernel/workqueue.c was omitted from generating kernel documentation. This
adds a new section "Workqueues and Kevents" and adds documentation for some
of the functions.
Some functions in this file already had DocBook-style comments, now they
finally become visible.

Also, since mm is so broad, it doesn't have a single person to maintain it,

Subject: [PATCH 0866/1026] [PATCH] inotify: fix deadlock found by lockdep
This is a real deadlock, a nice complex one:
(warning: long explanation follows so that Andrew can have a complete
patch description)
it's an ABCDA deadlock:
A iprune_mutex
B inode->inotify_mutex
C ih->mutex
D dev->ev_mutex
The AB relationship comes straight from invalidate_inodes()
int invalidate_inodes(struct super_block * sb)
{
int busy;
LIST_HEAD(throw_away);
mutex_lock(&iprune_mutex);
spin_lock(&inode_lock);
inotify_unmount_inodes(&sb->s_inodes);
where inotify_umount_inodes() takes the
mutex_lock(&inode->inotify_mutex);
The BC relationship comes directly from inotify_find_update_watch():
s32 inotify_find_update_watch(struct inotify_handle *ih, struct inode *inode,
u32 mask)
{
...
mutex_lock(&inode->inotify_mutex);
mutex_lock(&ih->mutex);
The CD relationship comes from inotify_rm_wd:
inotify_rm_wd does
mutex_lock(&inode->inotify_mutex);
mutex_lock(&ih->mutex)
and then calls inotify_remove_watch_locked() which calls
notify_dev_queue_event() which does
mutex_lock(&dev->ev_mutex);
(this strictly is a BCD relationship)
The DA relationship comes from the most interesting part:
[<ffffffff8022d9f2>] shrink_icache_memory+0x42/0x270
[<ffffffff80240dc4>] shrink_slab+0x11d/0x1c9
[<ffffffff802b5104>] try_to_free_pages+0x187/0x244
[<ffffffff8020efed>] __alloc_pages+0x1cd/0x2e0
[<ffffffff8025e1f8>] cache_alloc_refill+0x3f8/0x821
[<ffffffff8020a5e5>] kmem_cache_alloc+0x85/0xcb
[<ffffffff802db027>] kernel_event+0x2e/0x122
[<ffffffff8021d61c>] inotify_dev_queue_event+0xcc/0x140
inotify_dev_queue_event schedules a kernel_event which does a
kmem_cache_alloc( , GFP_KERNEL) which may try to shrink slabs, including
the inode cache .. which then takes iprune_mutex.
And voila, there is an AB, a BC, a CD relationship (even a direct BCD),
and also now a DA relationship -> a circular type AB-BA deadlock but
involving 4 locks.
The solution is simple: kernel_event() is NOT allowed to use GFP_KERNEL,
but must use GFP_NOFS to not cause recursion into the VFS.

Subject: [PATCH 0867/1026] [PATCH] Fix swsusp with PNP BIOS
swsusp is unable to suspend my machine (DTK FortisPro TOP-5A notebook) with
kernel 2.6.17.5 because it's unable to suspend PNP device 00:16 (mouse).
The problem is in PNP BIOS. pnp_bus_suspend() calls pnp_stop_dev() for the
device if the device can be disabled according to pnp_can_disable(). The
problem is that pnpbios_disable_resources() returns -EPERM if the device is
not dynamic (!pnpbios_is_dynamic()) but insert_device() happily sets
PNP_DISABLE capability/flag even if the device is not dynamic. So we try
to disable non-dynamic devices which will fail. This patch prevents
insert_device() from setting PNP_DISABLE if the device is not dynamic and
fixes suspend on my system.

failure path in ufs_symlink()
ufs_symlink, in one of its error paths, calls unlock_kernel without ever
having called lock_kernel(); fix this by creating and jumping to a new
label out_notlocked rather than the out label used after calling
lock_kernel().

Subject: [PATCH 0874/1026] [PATCH] Reducing local_bh_enable/disable overhead
in irqtrace
The recent changes from irqtrace feature has added overheads to
local_bh_disable and local_bh_enable that reduces UDP performance across
x86_64 and IA64, even though IA64 does not support the irqtrace feature.
Patch in question is
[PATCH]lockdep: irqtrace subsystem, core
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=c
ommit;h=de30a2b355ea85350ca2f58f3b9bf4e5bc007986
Prior to this patch, local_bh_disable was a short macro. Now it is a
function which calls __local_bh_disable with added irq flags save and
restore. The irq flags save and restore were also added to
local_bh_enable, probably for injecting the trace irqs code.
This overhead is on the generic code path across all architectures. On a
IA_64 test machine (Itanium-2 1.6 GHz) running a benchmark like netperf's
UDP streaming test, the added overhead results in a drop of 3% in
throughput, as udp_sendmsg calls the local_bh_enable/disable several times.
Other workloads that have heavy usages of local_bh_enable/disable could
also be affected. The patch ideally should not have affected IA-64
performance as it does not have IRQ tracing support. A significant portion
of the overhead is in the added irq flags save and restore, which I think
is not needed if IRQ tracing is unused. A suggested patch is attached
below that recovers the lost performance. However, the "ifdef"s in the
patch are a bit ugly.

Subject: [PATCH 0880/1026] [PATCH] vDSO hash-style fix
The latest toolchains can produce a new ELF section in DSOs and
dynamically-linked executables. The new section ".gnu.hash" replaces
".hash", and allows for more efficient runtime symbol lookups by the
dynamic linker. The new ld option --hash-style={sysv|gnu|both} controls
whether to produce the old ".hash", the new ".gnu.hash", or both. In some
new systems such as Fedora Core 6, gcc by default passes --hash-style=gnu
to the linker, so that a standard invocation of "gcc -shared" results in
producing a DSO with only ".gnu.hash". The new ".gnu.hash" sections need
to be dealt with the same way as ".hash" sections in all respects; only the
dynamic linker cares about their contents. To work with older dynamic
linkers (i.e. preexisting releases of glibc), a binary must have the old
".hash" section. The --hash-style=both option produces binaries that a new
dynamic linker can use more efficiently, but an old dynamic linker can
still handle.
The new section runs afoul of the custom linker scripts used to build vDSO
images for the kernel. On ia64, the failure mode for this is a boot-time
panic because the vDSO's PT_IA_64_UNWIND segment winds up ill-formed.
This patch addresses the problem in two ways.
First, it mentions ".gnu.hash" in all the linker scripts alongside ".hash".
This produces correct vDSO images with --hash-style=sysv (or old tools),
with --hash-style=gnu, or with --hash-style=both.
Second, it passes the --hash-style=sysv option when building the vDSO
images, so that ".gnu.hash" is not actually produced. This is the most
conservative choice for compatibility with any old userland. There is some
concern that some ancient glibc builds (though not any known old production
system) might choke on --hash-style=both binaries. The optimizations
provided by the new style of hash section do not really matter for a DSO
with a tiny number of symbols, as the vDSO has. If someone wants to use
=gnu or =both for their vDSO builds and worry less about that
compatibility, just change the option and the linker script changes will
make any choice work fine.

An attribute and entry timeout of zero should mean, that the entity is
invalidated immediately after the operation. Previously invalidation only
happened at the next clock tick.

Subject: [PATCH 0883/1026] [PATCH] fuse: use jiffies_64
It is entirely possible (though rare) that jiffies half-wraps around, while a
dentry/inode remains in the cache. This could mean that the dentry/inode is
not invalidated for another half wraparound-time.
To get around this problem, use 64-bit jiffies. The only problem with this is
that dentry->d_time is 32 bits on 32-bit archs. So use d_fsdata as the high
32 bits. This is an ugly hack, but far simpler, than having to allocate
private data just for this purpose.
Since 64-bit jiffies can be assumed never to wrap around, simple comparison
can be used, and a zero time value can represent "invalid".

I spent a long time the other day trying to examine an initrd image on a

Here is a patch which I hope will reduce future confusion for others.

+Compressed cpio images
+----------------------
+
+Recent kernels have support for populating a ramdisk from a compressed cpio
+archive, on such systems, the creation of a ramdisk image doesn't need to
+involve special block devices or loopbacks, you merely create a directory on
+disk with the desired initrd content, cd to that directory, and run (as an
+example):
+
+find . | cpio --quiet -c -o | gzip -9 -n > /boot/imagefile.img

vxfs_readdir
Commit 7b2fd697427e73c81d5fa659efd91bd07d303b0e in the historical GIT tree
stopped calling the readdir member of a file_operations struct with the big
kernel lock held, and fixed up all the readdir functions to do their own
locking. However, that change added calls to unlock_kernel() in
vxfs_readdir, but no call to lock_kernel(). Fix this by adding a call to
lock_kernel().

Based on a bug report from Russ Ross <russruss@gmail.com>
According to the spec:
"The remove request asks the file server both to remove the file
represented by fid and to clunk the fid, even if the remove fails."
but the Linux client seems to expect the fid to be valid after a failed
remove attempt. Specifically, I'm getting this behavior when attempting to
remove a non-empty directory.

Subject: [PATCH 0893/1026] [PATCH] fbdev: statically link the framebuffer
notification functions
The backlight and lcd subsystems can be notified by the framebuffer layer
of blanking events. However, these subsystems, as a whole, can function
independently from the framebuffer layer. But in order to enable to the
lcd and backlight subsystems, the framebuffer has to be compiled also,
effectively sucking in a huge amount of unneeded code.
To prevent dependency problems, separate out the framebuffer notification
mechanism from the framebuffer layer and permanently link it to the kernel.

Subject: [PATCH 0894/1026] [PATCH] radeonfb sleep fixes
Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw
too much power when suspended to RAM, reducing drastically the battery
lifetime. The solution is to enable suspend-to-D2 on these machines. They
are whitelisted through their subsystem vendor/device ID. This fixes
http://bugzilla.kernel.org/show_bug.cgi?id=3022
The patch introduces a framework to alter the pm_mode and reinit_func fields
of the radeonfb_info structure based on a whitelist. This should facilitate
future hardware-dependent workarounds. The workaround for the Samsung P35
that is already in the radeonfb code has been rewritten using this framework.
The behavior can be overridden with module options:
i) video=radeonfb:force_sleep=1

From: Michael Hanselmann <linux-kernel@hansmi.ch>
Date: Sun, 30 Jul 2006 03:04:19 -0700
Subject: [PATCH 0895/1026] [PATCH] powermac: More powermac backlight fixes
This patch fixes several problems:
- The legacy backlight value might be set at interrupt time. Introduced
a worker to prevent it from directly calling the backlight code.
- via-pmu allows the backlight to be grabbed, in which case we need to
prevent other kernel code from changing the brightness.
- Don't send PMU requests in via-pmu-backlight when the machine is about
to sleep or waking up.
- More Kconfig fixes.

CONFIG_FB_NVIDIA already depends on CONFIG_PCI in drivers/video/Kconfig.
Driver does an extra ``sanity check'' which is then redundant.

Subject: [PATCH 0897/1026] [PATCH] rivafb/nvidiafb: race between
register_framebuffer and *_bl_init
Since we now use the generic backlight infrastructure, I think we need to
call rivafb_bl_init before calling register_framebuffer since otherwise
rivafb_bl_init might race with the framebuffer layer already opening the
device and setting up the video mode. In this case we might end up with a
not yet fully intialized backlight (info->bl_dev still NULL) when calling
riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel
dies without any further notice during boot.
This fixes booting current git on a PB 6,1. In this case radeonfb/atyfb
would be affected too - I can fix that too but don't have any hardware to
test this on.

Subject: [PATCH 0898/1026] [CPUFREQ] return error when failing to set minfreq
I just stumbled on this bug/feature, this is how to reproduce it:
# echo 450000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
# echo 450000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
# echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
# cpufreq-info -p
450000 450000 powersave
# echo 1800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq ; echo $?
0
# cpufreq-info -p
450000 450000 powersave
Here it is. The kernel refuses to set a min_freq higher than the
max_freq but it allows a max_freq lower than min_freq (lowering min_freq
also).
This behaviour is pretty straightforward (but undocumented) and it
doesn't return an error altough failing to accomplish the requested
action (set min_freq).
The problem (IMO) is basically that userspace is not allowed to set a
full policy atomically while the kernel always does that thus it must
enforce an ordering on operations.
The attached patch returns -EINVAL if trying to increase frequencies
starting from scaling_min_freq and documents the correct ordering of writes.

Subject: [PATCH 0900/1026] [CPUFREQ] Longhaul - Workaround issues with APIC.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There is no need to worry about local APIC.
There is need to worry about I/O APIC, because I/O APIC
is replacing good old 8259. According to Nehemiah datasheet VIA is
using 3-wire bus to connect local APIC to I/O APIC.
"[...] When IA32_APIC_BASE[11] is set to 0, processor APICs based on the 3-wire APIC
bus cannot be generally re-enabled until a system hardware reset. The 3-wire bus
looses track of arbitration that would be necessary for complete re-enabling. Certain
(local) APIC functionality can be enabled. [...]"
So we must set disable bit for each interrupt in I/O APIC registers.
Same situation as for PIC - we must poke registers direcly.
How to do this? I don't know. So at the moment it is better to fail.

It seems commit 32ee8c3e470d86588b51dc42ed01e85c5fa0f180 accidentially
reverted cdc9cc1d740ffc3d8d8207fbf5df9bf05fcc9955, IOW, it reintroduced
the following compile error with CONFIG_PCI=n:

Subject: [PATCH 0913/1026] kbuild: improve error from file2alias
The original errormessage was just plain unreadable.
Sample error message after this update (not for real - I provoked it):
FATAL: drivers/net/s2io: sizeof(struct pci_device_id)=33 is not a modulo of the
size of section __mod_pci_device_table=160.
Fix definition of struct pci_device_id in mod_devicetable.h
Before a warning was generated - this is now a fatal error.

use irq_chip.name
Patch from David Brownell
ARM genirq cleanups/updates:
- Start switching platforms to newer APIs
* use "irq_chip" name, not "irqchip"
* providing irq_chip.name
- Show irq_chip.name in /proc/interrupts, like on x86.
This update a bit more than half of the ARM code. The irq_chip.name
values were chosen to match docs (if I have them) or be otherwise
obvious ("FPGA", "CPLD", or matching the code).

Subject: [PATCH 0920/1026] [ARM] 3743/1: ARM: OMAP: Fix compile for OMAP
Patch from Tony Lindgren
"clocks" is only needed only for CONFIG_OMAP_RESET_CLOCKS,
which turns of all unused clocks in with late_initcall. This is to kill
clocks that may have been left on by the bootloader. Having static and
non-static declaration of clocks makes omap_h2_1610_defconfig build fail.

There has been a problem in the radiotap header. Monitor mode
works now with tcpdump 3.94 + libpcap 0.9.4. ethereal 0.99.0 +
libpcap 0.9.4 is broken, because it doesn't find the right offset
for the IEEE 802.11 header.

info tag detection
Discovered a problem while accessing www.python.org on my PPC32.
The problem was pretty consistent for all sticks. The reason was
that while testing for the length info tag, I ignored the
endianess of the host system.
Please recognize that converting the constant to little endian, we
create faster code.

Subject: [PATCH 0933/1026] [IPV6]: Audit all ip6_dst_lookup/ip6_dst_store
calls
The current users of ip6_dst_lookup can be divided into two classes:
1) The caller holds no locks and is in user-context (UDP).
2) The caller does not want to lookup the dst cache at all.
The second class covers everyone except UDP because most people do
the cache lookup directly before calling ip6_dst_lookup. This patch
adds ip6_sk_dst_lookup for the first class.
Similarly ip6_dst_store users can be divded into those that need to
take the socket dst lock and those that don't. This patch adds
__ip6_dst_store for those (everyone except UDP/datagram) that don't
need an extra lock.

Subject: [PATCH 0935/1026] [NET]: Fix ___pskb_trim when entire frag_list needs
dropping
When the trim point is within the head and there is no paged data,
___pskb_trim fails to drop the first element in the frag_list.
This patch fixes this by moving the len <= offset case out of the
page data loop.
This patch also adds a missing kfree_skb on the frag that we just
cloned.

Otherwise we allow building appletalk drivers in-kernel when

by CONFIG_ATALK.

Subject: [PATCH 0938/1026] [TCP]: SNMPv2 tcpAttemptFails counter error
Refer to RFC2012, tcpAttemptFails is defined as following:
tcpAttemptFails OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of times TCP connections have made a direct
transition to the CLOSED state from either the SYN-SENT
state or the SYN-RCVD state, plus the number of times TCP
connections have made a direct transition to the LISTEN
state from the SYN-RCVD state."
::= { tcp 7 }
When I lookup into RFC793, I found that the state change should occured
under following condition:
1. SYN-SENT -> CLOSED
a) Received ACK,RST segment when SYN-SENT state.
2. SYN-RCVD -> CLOSED
b) Received SYN segment when SYN-RCVD state(came from LISTEN).
c) Received RST segment when SYN-RCVD state(came from SYN-SENT).
d) Received SYN segment when SYN-RCVD state(came from SYN-SENT).
3. SYN-RCVD -> LISTEN
e) Received RST segment when SYN-RCVD state(came from LISTEN).
In my test, those direct state transition can not be counted to
tcpAttemptFails.

Subject: [PATCH 0942/1026] [SECURITY] secmark: nul-terminate secdata
The patch below fixes a problem in the iptables SECMARK target, where
the user-supplied 'selctx' string may not be nul-terminated.
From initial analysis, it seems that the strlen() called from
selinux_string_to_sid() could run until it arbitrarily finds a zero,
and possibly cause a kernel oops before then.
The impact of this appears limited because the operation requires
CAP_NET_ADMIN, which is essentially always root. Also, the module is
not yet in wide use.

Subject: [PATCH 0943/1026] [TCP]: Process linger2 timeout consistently.
Based upon guidance from Alexey Kuznetsov.
When linger2 is active, we check to see if the fin_wait2
timeout is longer than the timewait. If it is, we schedule
the keepalive timer for the difference between the timewait
timeout and the fin_wait2 timeout.
When this orphan socket is seen by tcp_keepalive_timer()
it will try to transform this fin_wait2 socket into a
fin_wait2 mini-socket, again if linger2 is active.
Not all paths were setting this initial keepalive timer correctly.
The tcp input path was doing it correctly, but tcp_close() wasn't,
potentially making the socket linger longer than it really needs to.

Subject: [PATCH 0949/1026] [NET]: Kill the WARN_ON() calls for checksum
fixups.
We have a more complete solution in the works, involving
the seperation of CHECKSUM_HW on input vs. output, and
having netfilter properly do incremental checksums.
But that is a very involved patch and is thus 2.6.19
material.
What we have now is infinitely better than the past,
wherein all TSO packets were dropped due to corrupt
checksums as soon at the NAT module was loaded. At
least now, the checksums do get fixed up, it just
isn't the cleanest nor most optimal solution.

Subject: [PATCH 0950/1026] [IPV6]: SNMPv2 "ipv6IfStatsInHdrErrors" counter
error
When I tested Linux kernel 2.6.17.7 about statistics
"ipv6IfStatsInHdrErrors", found that this counter couldn't increase
correctly. The criteria is RFC2465:
ipv6IfStatsInHdrErrors OBJECT-TYPE
SYNTAX Counter3
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of input datagrams discarded due to
errors in their IPv6 headers, including version
number mismatch, other format errors, hop count
exceeded, errors discovered in processing their
IPv6 options, etc."
::= { ipv6IfStatsEntry 2 }
When I send TTL=0 and TTL=1 a packet to a router which need to be
forwarded, router just sends an ICMPv6 message to tell the sender that
TIME_EXCEED and HOPLIMITS, but no increments for this counter(in the
function ip6_forward).

Subject: [PATCH 0951/1026] [IPV6]: SNMPv2 "ipv6IfStatsOutFragCreates" counter
error
When I tested linux kernel 2.6.71.7 about statistics
"ipv6IfStatsOutFragCreates", and found that it couldn't increase
correctly. The criteria is RFC 2465:
ipv6IfStatsOutFragCreates OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of output datagram fragments that have
been generated as a result of fragmentation at
this output interface."
::= { ipv6IfStatsEntry 15 }
I think there are two issues in Linux kernel.
1st:
RFC2465 specifies the counter is "The number of output datagram
fragments...". I think increasing this counter after output a fragment
successfully is better. And it should not be increased even though a
fragment is created but failed to output.
2nd:
If we send a big ICMP/ICMPv6 echo request to a host, and receive
ICMP/ICMPv6 echo reply consisted of some fragments. As we know that in
Linux kernel first fragmentation occurs in ICMP layer(maybe saying
transport layer is better), but this is not the "real"
fragmentation,just do some "pre-fragment" -- allocate space for date,
and form a frag_list, etc. The "real" fragmentation happens in IP layer
-- set offset and MF flag and so on. So I think in "fast path" for
ip_fragment/ip6_fragment, if we send a fragment which "pre-fragment" by
upper layer we should also increase "ipv6IfStatsOutFragCreates".

Subject: [PATCH 0952/1026] [NET]: Remove lockdep_set_class() call from
skb_queue_head_init().
The skb_queue_head_init() function is used both in drivers for private use
and in the core networking code. The usage models are vastly set of
functions that is only softirq safe; while the driver usage tends to be
more limited to a few hardirq safe accessor functions. Rather than
annotating all 133+ driver usages, for now just split this lock into a per
queue class. This change is obviously safe and probably should make
2.6.18.

Subject: [PATCH 0954/1026] [AF_UNIX]: Kernel memory leak fix for af_unix
datagram getpeersec patch
From: Catherine Zhang <cxzhang@watson.ibm.com>
This patch implements a cleaner fix for the memory leak problem of the
original unix datagram getpeersec patch. Instead of creating a
security context each time a unix datagram is sent, we only create the
security context when the receiver requests it.
This new design requires modification of the current
unix_getsecpeer_dgram LSM hook and addition of two new hooks, namely,
secid_to_secctx and release_secctx. The former retrieves the security
context and the latter releases it. A hook is required for releasing
the security context because it is up to the security module to decide
how that's done. In the case of Selinux, it's a simple kfree
operation.

Subject: [PATCH 0955/1026] [DECNET]: Fix for routing bug
This patch fixes a bug in the DECnet routing code where we were
selecting a loopback device in preference to an outward facing device
even when the destination was known non-local. This patch should fix
the problem.

net_dma_rebalance
Remove the lock_cpu_hotplug()/unlock_cpu_hotplug() calls from
net_dma_rebalance
The lock_cpu_hotplug()/unlock_cpu_hotplug() sequence in
net_dma_rebalance is both incorrect (as pointed out by David Miller)
because lock_cpu_hotplug() may sleep while the net_dma_event_lock
spinlock is held, and unnecessary (as pointed out by Andrew Morton) as
spin_lock() disables preemption which protects from CPU hotplug
events.

Subject: [PATCH 0961/1026] [IA64] Do not assume output registers be
reservered.
We found an issue in pal.S.
According to the software runtime SPEC,
The caller's output registers do not need to be preserved for
caller. The callee may reuse input registers for any other
purpose within the procedure.
in ia64_pal_call_phys_stacked,
input registers are copied to output registers before call
into ia64_switch_mode_phys, then used to call into PAL. This
assumes output registers are preserved in ia64_switch_mode_phys,
which may not be true.
In this particular case, ia64_switch_mode_phys alloc a null frame
, and mask off psr.i.
If an interrupt comes at this small window,
or an MCA comes inside the procedure, output registers
maybe changed,
then the pal call may got some staled input registers.
This patch moves the copies from input to output
after ia64_switch_mode_phys to follow the software
runtime convention.
It also removed some unused labels in
ia64_pal_call_phys_stacked.

Subject: [PATCH 0963/1026] USB: AT91 UDC updates, mostly power management
UDC updates for AT91 series processors:
- Get ready for at91sam926x processors (ARMv5tej not ARMv4t)
- Suspend/resume support now behaves properly
- In "standby" mode, UDC can be a source of system wakeup events
(host resume, device connect/disconnect, etc)
- Fix IRQ storming issues, seemingly related to clock disabling
changes that went in a while back
And minor cleanups, especially whitespace.

Portions copied from the Keyspan driver by Hugh Blemings <hugh@blemings.org>
- History:
-
- 2005-05-19 v0.1 Initial version, based on incomplete docs
- and analysis of misbehavior with the standard driver
- 2005-05-20 v0.2 Extended the input buffer to avoid losing
- random 64-byte chunks of data
- 2005-05-21 v0.3 implemented chars_in_buffer()
- turned on low_latency
- simplified the code somewhat
- 2005-05-24 v0.4 option_write() sometimes deadlocked under heavy load
- removed some dead code
- added sponsor notice
- coding style clean-up
- 2005-06-20 v0.4.1 add missing braces :-/
- killed end-of-line whitespace
- 2005-07-15 v0.4.2 rename WLAN product to FUSION, add FUSION2
- 2005-09-10 v0.4.3 added HUAWEI E600 card and Audiovox AirCard
- 2005-09-20 v0.4.4 increased recv buffer size: the card sometimes
- wants to send >2000 bytes.
- 2006-04-10 v0.5 fixed two array overrun errors :-/
- 2006-04-21 v0.5.1 added support for Sierra Wireless MC8755
- 2006-05-15 v0.6 re-enable multi-port support
- 2006-06-01 v0.6.1 add COBRA
- 2006-06-01 v0.6.2 add backwards-compatibility stuff
- 2006-06-01 v0.6.3 add Novatel Wireless
- 2006-06-01 v0.7 Option => GSM
- 2006-06-01 v0.7.1 add COBRA2

Subject: [PATCH 0966/1026] USB: Option driver: Short driver names were
identical
The short driver names were not unique,
which prevented the driver from actually loading.
Also, one of the ioctl pointers was missing.

Subject: [PATCH 0971/1026] USB: adding support for SHARP WS003SH to ipaq.c
This small patch enables a support of "SHARP WS003SH".
"SHARP WS003SH" (usullary called "W-ZERO3") is most polular All-in-one handheld
CellPhone-plus-WindowsMobile5.0 in Japan.
"SHARP WS003SH" has two modes, "Modem" and "ActiveSync".
But, "ActiveSync" mode uses NDIS connection.
Therefore, ipaq.c can only support "Modem" mode.

Subject: [PATCH 0973/1026] USB: New USB ID for Belkin Serial Adapter
Can you add the USB IDs for the Belkin USB Serial adapter (P/N F5U257)
to the pl2303 driver in the Linux Kernel? Are you the appropriate person
to approach for this?
I recently purchased a Belkin USB Serial adapter (P/N F5U257) and found
that it didn't work. After a bit of experimentation I found that it
works with the pl2303 driver once the ID has been added. See attached
patch to fix this. Also attached is the output from lsusb -v just in
case you require any information from there.

Subject: [PATCH 0974/1026] usb-storage: Add US_FL_IGNORE_DEVICE flag; ignore
ZyXEL G220F
This patch adds a new unusual_devs flag for when usb-storage needs to ignore
a device that it would otherwise claim.
We need to ignore the ZyXEL G220F as it is a virtual CDROM drive which
includes the windows driver for this USB-WLAN adapter. After the windows
driver is installed on a windows system, it converts it into a WLAN adapter
(by ejecting the virtual disc).
The virtual CDROM is of no interest to Linux users. The zd1211rw driver will
automatically perform the eject operation, we just need to ensure that
usb-storage does not claim the device.

In the event there are reports of breakage, we should revert this patch,

The RTL8150 driver currently crashes the kernel if the USB lead is unplugged
while the device is active. The attached patch adds error handling to
tell the network layer that the device has gone away when the device is
unplugged. With this patch, the device can be plugged and unplugged
to one's hearts' content, without crashing anything.
Oh, I've also added rudimentary suspend and resume methods.

Subject: [PATCH 0980/1026] USB: ati_remote.c: autorepeat fix
When HZ is set to 250 (new default) or 100, the time span during which
repeated events from the device are ignored could be too small due to
ms->jiffies rounding. This causes the auto repeat to kick in early making
it impossible for the user to generate individual press/release events.
Increate the timeout to compensate.

that the bit is unchanged; in fact, the driver no longer looks at SPD at
all.

Subject: [PATCH 0987/1026] Fix force_sig_info() semantics after cleanups
Suresh points out that commit b0423a0d9cc836b2c3d796623cd19236bfedfe63
broke the semantics of a synchronous signal like SIGSEGV occurring
recursively inside its own handler handler (or, indeed, any other
context when the signal was blocked).
That was unintentional, and this fixes things up by reinstating the old
semantics, but without reverting the cleanups.

stacks
Re-add backlink for old style unwinder to stack switching. Add proper
stack frame and CFI annotations to call_softirq
This prevents a oops when backtracing with fallback through the
interrupt stack top.
Suggested by Jan Beulich and Herbert Xu wanted it in 2.6.18.

where no HW IOMMU is present in the machine and we end up using nommu,
leaving force_iommu set to 1 causes dma_alloc_coherent to do the wrong
thing. Therefore, if we end up using nommu, make sure force_iommu is

Subject: [PATCH 0990/1026] [PATCH] fix faulty inode data collection for open()
with O_CREAT
When the specified path is an existing file or when it is a symlink, audit
collects the wrong inode number, which causes it to miss the open() event.
Adding a second hook to the open() path fixes this.
Also add audit_copy_inode() to consolidate some code.

Subject: [PATCH 0998/1026] IB/mthca: Fix mthca_array_clear() thinko
mthca_array_clear() does not clear the slot if the used count is
positive. This leads to crashes in mthca_qp_event() since that uses
mthca_array_get() to check that the qp is valid.
Discovered by Ali Ayoub.

Subject: [PATCH 1003/1026] [IA64] align high endpoint of VIRTUAL_MEM_MAP
Assure that vmem_map's high endpoint is MAX_ORDER aligned. Not doing so violates
the buddy allocator algorithm. Also anyone using mem=XXX on boot line and
not aligned to MAX_ORDER requires this patch in order to satisfy buddy
allocator. vmem_map always starts at pfn 0. The potentially large MAX_ORDER
on ia64 (due to hugetlbfs) requires that the end of vmem_map be aligned
to MAX_ORDER_NR_PAGES.
This was boot tested for: FLATMEM, FLATMEM+VIRTUAL_MEM_MAP,
DISCONTIGMEM+VIRTUAL_MEM_MAP and SPARSEMEM.

Subject: [PATCH 1004/1026] [IA64] fix show_mem for VIRTUAL_MEM_MAP+FLATMEM
contig.c (FLATMEM) requires the same optimization as in discontig.c for show_mem
when VIRTUAL_MEM_MAP is in use. Otherwise FLATMEM has softlockup timeouts.
This was boot tested for memory configuration: SPARSEMEM,
DISCONTIG+VIRTUAL_MEM_MAP, FLATMEM, FLATMEM+VIRTUAL_MEM_MAP and
FLATMEM+VIRTUAL_MEM_MAP with largest memory gap less than LARGE_GAP by
using boot parameter "mem=".
This was boot tested and "echo m >/proc/sysrq-trigger" output evaluated for
: FLATMEM, FLATMEM+VIRTUAL_MEM_MAP, DISCONTIGMEM+VIRTUAL_MEM_MAP and
SPARSEMEM.

Subject: [PATCH 1007/1026] IB/uverbs: Avoid a crash on device hot remove
Wait until all users have closed their device context before allowing
device unregistration to complete. This prevents a crash caused by
referring to stale data structures.
A better solution would be to have a way to revoke contexts rather
than waiting for userspace to close the context, but that's a much
bigger change that will have to wait. For now let's at least avoid
the crash.

Subject: [PATCH 1013/1026] PCI: docking station: remove dock uevents
Remove uevent dock notifications. There are no consumers
of these events at present, and uevents are likely not the
correct way to send this type of event anyway.
Until I get some kind of idea if anyone in userspace cares
about dock events, I will just not send any.

Subject: [PATCH 1020/1026] [PATCH] s2io driver bug fixes #1
This patch contains some of the bug fixes and enhancements done to
s2io driver. Following are the brief description of changes
1. Introduced macro "S2IO_PARM_INT" for declaring integer load parameter
2. UDP_RR test failure, memset txdl after Tx completion
3. PXE boot may leave adapter in unknown state so do reset in probe.
4. Add Tx completion code in netpoll
5. In s2io_vpd_read() move array vpd_data[] to pointer, saves stack memory
6. Fix bug in ethtool online test

Subject: [PATCH 1021/1026] [PATCH] s2io driver bug fixes #2
This patch contains some of the bug fixes and enhancements done to
s2io driver. Following are the brief description of changes
1. code cleanup to handle gso modification better
2. Move repeated code in rx path, to a common function
s2io_chk_rx_buffers()
3. Bug fix in MSI interrupt
4. clear statistics when card is down
5. Avoid linked list traversing in lro aggregation.
6. Use pci_dma_sync_single_for_cpu for buffer0 in case of 2/3
buffer mode.
7. ethtool tso get/set functions to set clear NETIF_F_TSO6
8. Stop LRO aggregation when we receive ECN notification

Subject: [PATCH 1022/1026] [PATCH] Stop calling phy_stop_interrupts() twice
Prevent phylib from freeing PHY IRQ twice on closing an eth device:
phy_disconnect() first calls phy_stop_interrupts(), then it calls
phy_stop_machine() which in turn calls phy_stop_interrupts() making the
kernel complain on each bootup...

Subject: [PATCH 1026/1026] [IA64] make uncached allocator more node aware
The uncached allocator has a function, uncached_get_new_chunk(), that needs
to be serialized on a per node basis. It also has a global variable,
allocated_granules, which should be defined on a per node basis and protected
by that serialization. Additionally, all error returns from functions called
(like ia64_pal_mc_drain()) should be handled appropriately.
