- The list "struct class.children" is supposed to be protected by
class.sem, not by class.subsys.rwsem.
- nodemgr_remove_uds() iterated over nodemgr_ud_class.children without
proper protection. This was never observed as a bug since the code
is usually only accessed by knodemgrd. All knodemgrds are currently
globally serialized. But userspace can trigger this code too by
writing to /sys/bus/ieee1394/destroy_node.
- Clean up access to the FireWire bus type's subsys.rwsem: Access it
uniformly via ieee1394_bus_type. Shrink rwsem protected regions
where possible. Expand them where necessary. The latter wasn't a
problem so far because knodemgr is globally serialized.
This should harden the interaction of ieee1394 with sysfs and lay ground
for deserialized operation of multiple knodemgrds and for implementation
of subthreads for parallelized scanning and probing.

video1394 does not need to take the BKL. The data structures shared between
file_operations and interrupts are already protected through context-specific
spinlocks.
The only other danger is video1394_release() being called during another
operation, however this cannot happen because release is only ever invoked
when the last thread has closed the fd.

I did a quick shot on what I described and the appended patch
does the first thing needed for working suspend/resume
in ohci1394 which is HW de- and re-initialisation.
It works with suspend2disk on my Ricoh R5C552 IEEE 1394 Controller
with the 2.6.17 kernel to the extent that if I call dvgrab --interactive
after suspend2disk without unloading ohci1394, it does not lock up
dvgrab with 100% CPU but properly connects to the camera, given
that I first unplug and plug the camera after coming back from
suspend.
I guess that could be fixed by forcing a bus reset in the resume
function.
I cannot test suspend to RAM here at the moment and should
follow the guidelines in Documentation/power/pci.txt also,
so this is rather a quick report than a finished patch and
there are some rough edges:
However, with this patch, I have to unload at least some in-kernel
users of ohci1394 like dv1394 or video1394 before suspending.
Not doing that caused an Oops and a bad tasklet error, probably from
not handling ISO tasklets during suspend/resume properly.
Maybe these can be temporarily cleared or unregistered and
re-registered for suspend/resume with help from the other
layers or from the highlevel 1394 core, but I do not really
know what these do.
But this patch provides a useful base to start from and is
already of much help for people which do not need dv1394
and video1394 or can unload them at least during suspend.
I cannot test function with sbp2 at the moment, but raw1394
seems to work fine.

This allows workqueue users to run just their own pending work, rather
than wait for the whole workqueue to finish running. This solves the
deadlock with networking libphy that was due to other workqueue entries
possibly needing a lock that was held by the routine that wanted to
flush its own work.
It's not wonderful: if you absolutely need to synchronize with the work
function having been executed, any user strictly speaking should have
its own completion tracking logic, since when we run things explicitly
by hand, the generic workqueue layer can no longer help us synchronize.
Also, this is strictly only usable for work that has been scheduled
without any delayed timers. You can not mix the new interface with
schedule_delayed_work().
But it's better than what we had currently.

The iop348 processor integrates an Xscale (XSC3 512KB L2 Cache) core with a
Serial Attached SCSI (SAS) controller, multi-ported DDR2 memory
controller, 3 Application Direct Memory Access (DMA) controllers, a 133Mhz
PCI-X interface, a x8 PCI-Express interface, and other peripherals to form
a system-on-a-chip RAID subsystem engine.
The iop342 processor replaces the SAS controller with a second Xscale core
for dual core embedded applications.
The iop341 processor is the single core version of iop342.
This patch supports the two Intel customer reference platforms iq81340mc
for external storage and iq81340sc for direct attach (HBA) development.

The IPMI BT subdriver has been patched to survive "long busy" timeouts seen
during firmware upgrades and resets. The patch never returns the HOSED state,
synthesizes response messages with meaningful completion codes, and recovers
gracefully when the hardware finishes the long busy. The subdriver now issues
a "Get BT Capabilities" command and properly uses those results. More
informative completion codes are returned on error from transaction starts;
this logic was propogated to the KCS and SMIC subdrivers. Finally, indent and
other style quirks were normalized.

The most notable issue is that the OMAP IRQ code doesn't yet support the

There was lots of #ifdef noise in the kernel due to hotcpu_notifier(fn,

generating compiler warnings of unused symbols, hence forcing people to add

the compiler can skip truly unused functions just fine:

A driver for the PCEngines WRAP boards (http://www.pcengines.ch), which are
very similar to the Soekris net4801 (same NS SC1100 geode reference
design).
The LEDs on the WRAP are on different GPIO lines and I have modified and
copied the net48xx error led support for this. It also includes support
for an "extra" led (in addition to error). The three LEDs on the WRAP are
at GPIO lines 2,3,18 (WRAP LEDs from left to right). This driver gives
access to the second and third LEDs by twiddling GPIO lines 3 & 18.
Because these boards are so similar to the net48xx, I basically sed-ed that
driver to form the basis for leds-wrap.c. The only changes from
leds-net48xx.c are:
- #define WRAP_EXTRA_LED_GPIO
- name changes
- duplicate relevant sections to provide support for the "extra" led
- reverse the various *_led_set values. The WRAP is "backwards" from the
net48xx, and these needed to be updated for that.

Clean up several code points in which the return code from misc_register is
not handled properly.
Several modules failed to deregister various hooks when misc_register fails,
and this patch cleans them up. Also there are a few modules that legitimately
don't care about the failure status of misc register. These drivers however
unilaterally call misc_deregister on module unload.
Since misc_register doesn't initialize the list_head in the init_routine if it
fails, the deregister operation is at risk for oopsing when list_del is
called. The initial solution was to manually init the list in the miscdev
structure in each of those modules, but the consensus in this thread was to
consolodate and do that universally inside misc_register.

For node-aware skb allocations we need information about the node in struct
net_device or struct device. Davem suggested to put it into struct device
which this patch does.
In particular:
- struct device gets a new int numa_node member if CONFIG_NUMA is set
- there are two new helpers, dev_to_node and set_dev_node to
transparently deal with the non-numa case
- for pci devices the node-info is set to the value we get from
pcibus_to_node.
Note that for some architectures pcibus_to_node doesn't work yet at the time
we call it currently. This is harmless and will just mean skb allocations
aren't node-local on this architectures until the implementation of
pcibus_to_node on these architectures have been updated (There are patches for
x86 and x86_64 floating around)

This patch converts sata_promise to use new-style libata error
handling on Promise SATA chips, for both SATA and PATA ports.
* ATA_FLAG_SRST is no longer set
* ->phy_reset is no longer set as it is unused when ->error_handler
is present, and pdc_sata_phy_reset() has been removed
* pdc_freeze() masks interrupts and halts DMA via PDC_CTLSTAT
* pdc_thaw() clears interrupt status in PDC_INT_SEQMASK and then
unmasks interrupts in PDC_CTLSTAT
* pdc_error_handler() reinitialises the port if it isn't frozen,
and then invokes ata_do_eh() with standard {s,}ata reset methods
* pdc_post_internal_cmd() resets the port in case of errors
* the PATA-only 20619 chip continues to use old-style EH:
not by necessity but simply because I don't have documentation
for it or any way to test it
Since the previous version pdc_error_handler() has been rewritten
and it now mostly matches ahci and sata_sil24. In case anyone
wonders: the call to pdc_reset_port() isn't a heavy-duty reset,
it's a light-weight reset to quickly put a port into a sane state.
The discussion about the PCI flushes in pdc_freeze() and pdc_thaw()
seemed to end with a consensus that the flushes are OK and not
obviously redundant, so I decided to keep them for now.
This patch was prepared against 2.6.19-git7, but it also applies
to 2.6.19 + libata #upstream, with or without the revised sata_promise
cleanup patch I recently submitted.
This patch does conflict with the #promise-sata-pata patch:
this patch removes pdc_sata_phy_reset() while #promise-sata-pata
modifies it. The correct patch resolution is to remove the function.

This patch performs two simple cleanups of sata_promise.
* Remove board_20771 and map device id 0x3577 to board_2057x.
After the recent corrections for SATAII chips, board_20771 and
board_2057x were equivalent in the driver.
* Remove hp->hotplug_offset and use hp->flags & PDC_FLAG_GEN_II
to compute hotplug_offset in pdc_host_init(). hp->hotplug_offset
was used to distinguish 1st and 2nd generation chips in one
particular case, but now we have that information in a more
general form in hp->flags, so hp->hotplug_offset is redundant.
Changes since previous submission: rebased on libata-dev #upstream,
cleaned up hotplug_offset computation based on Tejun's comments,
expanded hotplug_offset removal rationale.
This patch does not depend on the pending new EH conversion patch.

Add Tg3_FLG2_IS_NIC flag to unambiguously determine whether the
device is NIC or onboard. Previously, the EEPROM_WRITE_PROT flag was
overloaded to also mean onboard. With the separation, we can
support some devices that are onboard but do not use eeprom write
protect.

LRW-32-AES needs a certain IV. This IV should be provided dm-crypt.
The block cipher mode could, in principle generate the correct IV from
the plain IV, but I think that it is cleaner to supply the right IV
directly.
The sector -> narrow block calculation uses a shift for performance reasons.
This shift is computed in .ctr and stored in cc->iv_gen_private (as a void *).

Two legacy power management modes are much easier to just explicitly disable
when running in paravirtualized mode - neither APM nor PnP is still relevant.
The status of ACPI is still debatable, and noacpi is still a common enough
boot parameter that it is not necessary to explicitly disable ACPI.

Create a paravirt.h header for all the critical operations which need to be
replaced with hypervisor calls, and include that instead of defining native
operations, when CONFIG_PARAVIRT.
This patch does the dumbest possible replacement of paravirtualized
instructions: calls through a "paravirt_ops" structure. Currently these are
function implementations of native hardware: hypervisors will override the ops
structure with their own variants.
All the pv-ops functions are declared "fastcall" so that a specific
register-based ABI is used, to make inlining assember easier.
And:
+From: Andy Whitcroft <apw@shadowen.org>
The paravirt ops introduce a 'weak' attribute onto memory_setup().
Code ordering leads to the following warnings on x86:
arch/i386/kernel/setup.c:651: warning: weak declaration of
`memory_setup' after first use results in unspecified behavior
Move memory_setup() to avoid this.
