ap->id is logcial port ID which is unique among all ATA ports and
doesn't have anything to do with hardware port index. ap->port_no is
the hardware port index and thus should be used when clearing IRQ mask
in ahci_thaw().

On the Maple board, the AMD8111 IDE is in legacy mode... except that it
appears on IRQ 20 instead of IRQ 15. For drivers/ide this was handled by
the architecture's "pci_get_legacy_ide_irq()" function, but in libata we
just hard-code the numbers 14 and 15.
This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as
appropriate, having added a pci_dev argument to the
ATA_{PRIM,SECOND}ARY_IRQ macros.
There's probably a better way to do this -- especially if we observe
that the _only_ case in which this seemingly-generic
"pci_get_legacy_ide_irq()" function returns anything other than 14 and
15 for primary and secondary respectively is the case of the AMD8111 on
the Maple board -- couldn't we handle that with a special case in the
pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into
native mode during early boot and assign resources properly?

Before hardreset, ahci initialized stat part of received FIS area to
0xff to wait for the first D2H Reg FIS which would change the value to
device ready state. This used to work but now libata considers status
value of 0xff as device not present making this wait prone to failure.
This patch makes ahci use 0x80 for the wait stat value instead of
0xff to fix the above problem.

If a GFP_KERNEL allocation is attempted in md while the mddev_lock is held,
it is possible for a deadlock to eventuate.
This happens if the array was marked 'clean', and the memalloc triggers a
write-out to the md device.
For the writeout to succeed, the array must be marked 'dirty', and that
requires getting the mddev_lock.
So, before attempting a GFP_KERNEL allocation while holding the lock, make
sure the array is marked 'dirty' (unless it is currently read-only).

Allow noflush suspend/resume of device-mapper device only for the case
where the device size is unchanged.
Otherwise, dm-multipath devices can stall when resumed if noflush was used
when suspending them, all paths have failed and queue_if_no_path is set.
Explanation:
1. Something is doing fsync() on the block dev,
holding inode->i_sem
2. The fsync write is blocked by all-paths-down and queue_if_no_path
3. Someone requests to suspend the dm device with noflush.
Pending writes are left in queue.
4. In the middle of dm_resume(), __bind() tries to get
inode->i_sem to do __set_size() and waits forever.
'noflush suspend' is a new device-mapper feature introduced in
early 2.6.20. So I hope the fix being included before 2.6.20 is
released.
Example of reproducer:
1. Create a multipath device by dmsetup
2. Fail all paths during mkfs
3. Do dmsetup suspend --noflush and load new map with healthy paths
4. Do dmsetup resume

Recently cpufreq support on my laptop (Lenovo T60) broke completely: when
it's plugged into AC it would never go higher than 1 GHz - neither 1.3 GHz
nor 1.83 GHz is possible - no matter which governor (userspace, speed or
ondemand) is used.
After some cpufreq debugging i tracked the regression back to the following
(totally correct) bug-fix commit:
commit 0916bd3ebb
Author: Dave Jones <davej@redhat.com>
Date: Wed Nov 22 20:42:01 2006 -0500
[PATCH] Correct bound checking from the value returned from _PPC method.
This bugfix, which makes other laptops work, made a previously hidden
(BIOS) bug visible on my laptop.
The bug is the following: if the _PPC (Performance Present Capabilities)
optional ACPI object is queried /after/ bootup then the BIOS reports an
incorrect value of '2'.
My laptop (Lenovo T60) has the following performance states supported:
0: 1833000
1: 1333000
2: 1000000
Per ACPI specification, a _PPC value of '0' means that all 3 performance
states are usable. A _PPC value of '1' means states 1 .. 2 are usable, a
value of '2' means only state '2' (slowest) is usable.
now, the _PPC object is optional, and it also comes with notification.
Furthermore, when a CPU object is initialized, the _PPC object is
initialized as well. So the following evaluation of the _PPC object is
superfluous:
[<c028ba5f>] acpi_processor_get_platform_limit+0xa1/0xaf
[<c028c040>] acpi_processor_register_performance+0x3b9/0x3ef
[<c0111a85>] acpi_cpufreq_cpu_init+0xb7/0x596
[<c03dab74>] cpufreq_add_dev+0x160/0x4a8
[<c02bed90>] sysdev_driver_register+0x5a/0xa0
[<c03d9c4c>] cpufreq_register_driver+0xb4/0x176
[<c068ac08>] acpi_cpufreq_init+0xe5/0xeb
[<c010056e>] init+0x14f/0x3dd
And this is the point where my laptop's BIOS returns the incorrect value of
'2'. Note that it has not sent any notification event, so the value is
probably not really intentional (possibly spurious), and Windows likely
doesnt query it after bootup either. Maybe the value is kept at '2'
normally, and is only set to the real value when a true asynchronous event
(such as AC plug event, battery switch, etc.) occurs.
So i /think/ this is a grey area of the ACPI spec: per the letter of the
spec the _PPC value only changes when notified, so there's no reason to
query it after the system has booted up. So in my opinion the best (and
most compatible) strategy would be to do the change below, and to not
evaluate the _PPC object in the acpi_processor_get_performance_info() call,
but only evaluate it if _PPC is present during CPU object init, or if it's
notified during an asynchronous event. This change is more permissive than
the previous logic, so it definitely shouldnt break any existing system.
This also happens to fix my laptop, which is merrily chugging along at
1.83 GHz now. Yay!

If a SPI master device exists, udev (udevtrigger) causes kernel crash, due
to wrong kobj pointer in kobject_uevent_env(). This problem was not in
2.6.19.
The backtrace (on MIPS) was:
[<8024db6c>] kobject_uevent_env+0x54c/0x5e8
[<802a8264>] store_uevent+0x1c/0x3c (in drivers/class.c)
[<801cb14c>] subsys_attr_store+0x2c/0x50
[<801cb80c>] flush_write_buffer+0x38/0x5c
[<801cb900>] sysfs_write_file+0xd0/0x190
[<80181444>] vfs_write+0xc4/0x1a0
[<80181cdc>] sys_write+0x54/0xa0
[<8010dae4>] stack_done+0x20/0x3c
flush_write_buffer() passes kobject of spi_master_class.subsys to
subsys_addr_store(), then subsys_addr_store() passes a pointer to a struct
subsystem to store_uevent() which expects a pointer to a struct
class_device. The problem seems subsys_attr_store() called instead of
class_device_attr_store().
This mismatch was caused by commit
3bd0f69435, which overrides kset of master
class. This made spi_master_class.subsys.kset.ktype NULL so
subsys_sysfs_ops is used instead of class_dev_sysfs_ops.
The commit was to fix spi_busnum_to_master(). Here is a patch fixes
this function in other way, just searching children list of
class_device.

2. Setting the accessed bit is simplified.
3. Under some circumstances, we used to pretend a page fault was fixed when

Some ATA/ATAPI devices act weirdly after the link is put into slumber
mode. Some hang completely requiring physical power removal while
others fail to wake up till the link is hardreset a couple of times.
The addition of slumber on power down was never driven by real need.
It just followed what ahci spec said literally. The spec itself seems
faulty in that it doesn't consider devices (not controllers) which
don't support link powersaving mode.
Theory never matches reality when it comes to dark allys of cheap
ATA/ATAPI world. It's just unrealistic to expect vendors to test
rarely used link powersaving feature rigorously. This patch makes
ahci more friendly to the coldness of reality.
This shouldn't have any negative effect - when suspend operation
succeeds, we power off the whole machine; otherwise, we wake up
everything. I can't see any reason to be so elaborate with powering
down the link in the first place.

Several people reported issues with certain drive commands timing out on
sata_nv controllers running in ADMA mode. The commands in question were
non-DMA-mapped commands, usually FLUSH CACHE or FLUSH CACHE EXT.
From experimentation it appears that the NV_INT_DEV indication isn't
always set when a legitimate command completion interrupt is received on
a legacy-mode command, at least not on these controllers in ADMA mode.
When a command is pending on the port, force the flag on always in the
irq_stat value before calling nv_host_intr so that the drive busy state
is always checked by ata_host_intr.
This also fixes some questionable code in nv_host_intr which called
ata_check_status when a command was pending and ata_host_intr returned
"unhandled". If the device interrupted at just the wrong time this could
cause interrupts to be lost.

If a page is marked as dirty in the guest pte, set_pte_common() can set the
writable bit on newly-instantiated shadow pte. This optimization avoids
a write fault after the initial read fault.
However, if a write fault instantiates the pte, fix_write_pf() incorrectly
reports the fault as a guest page fault, and the guest oopses on what appears
to be a correctly-mapped page.
Fix is to detect the condition and only report a guest page fault on a user
access to a kernel page.
With the fix, a kvm guest can survive a whole night of running the kernel
hacker's screensaver (make -j9 in a loop).

The various bit string instructions (bts, btc, etc.) fail to adjust the
address correctly if the bit address is beyond BITS_PER_LONG.
This bug creeped in as the emulator originally relied on cr2 to contain the
memory address; however we now decode it from the mod r/m bits, and must
adjust the offset to account for large bit indices.
The patch is rather large because it switches src and dst decoding around, so
that the bit index is available when decoding the memory address.
This fixes workloads like the FC5 installer.

The kvm mmio read path looks like:
1. guest read faults
2. kvm emulates read, calls emulator_read_emulated()
3. fails as a read requires userspace help
4. exit to userspace
5. userspace emulates read, kvm sets vcpu->mmio_read_completed
6. re-enter guest, fault again
7. kvm emulates read, calls emulator_read_emulated()
8. succeeds as vcpu->mmio_read_emulated is set
9. instruction completes and guest is resumed
A problem surfaces if the userspace exit (step 5) also requests an interrupt
injection. In that case, the guest does not re-execute the original
instruction, but the interrupt handler. The next time an mmio read is
exectued (likely for a different address), step 3 will find
vcpu->mmio_read_completed set and return the value read for the original
instruction.
The problem manifested itself in a few annoying ways:
- little squares appear randomly on console when switching virtual terminals
- ne2000 fails under nfs read load
- rtl8139 complains about "pci errors" even though the device model is
incapable of issuing them.
Fix by skipping interrupt injection if an mmio read is pending.
A better fix is to avoid re-entry into the guest, and re-emulating immediately
instead. However that's a bit more complex.

Different AX88772 dongles use different PHYs; the chip is capable of using
both a primary and secondary PHY, and supports an internal and external PHY.
It appears that some DUB-E100 devices use the internal PHY, so trying to use
an external one will not work (note that this is different across revisions,
as well; the "A" and "B" revs of the DUB-E100 use different PHYs!). The data
sheet for the AX88772 chip specifies that the internal PHY id will be 0x10,
so if that's read from the EEPROM, we should use that rather than attempting
to use an external PHY.

It's not safe in cp_start_xmit to blindly call spin_lock_irq and then
spin_unlock_irq, since it may very well be the case that cp_start_xmit
was called with interrupts already disabled (I came across this bug in
the context of netdump in RedHat kernels, but the same issue holds, for
example, in netconsole). Therefore, replace all instances of
spin_lock_irq and spin_unlock_irq with spin_lock_irqsave and
spin_unlock_irqrestore, respectively, in cp_start_xmit(). I tested this
against a fully-virtualized Xen guest using netdump, which happens to
use the 8139cp driver to talk to the emulated hardware. I don't have a
real piece of 8139cp hardware to test on, so someone else will have to

Host endianess does not affect the order that pixel rgb data comes
in from the quickcam (the values are bytes, not words or longs). The
driver is erroniously swapping the order of rgb values for big endian
machines. This patch is needed get the Quickcam communicator working
on big endian machines (tested on powerpc)

Suspending with the cx88xx module loaded causes the system to lock up
because the cx88_audio_thread kthread was missing a try_to_freeze()
call, which caused it to go into a tight loop and result in softlockup
when suspending. Fix that.

vivi.c uses the KM_BOUNCE_READ with local interrupts enabled.
This means that if a disk interrupt occurs while vivi.c is using this
fixmap slot, the vivi.c driver will, upon return from that interrupt, find
that the fixmap slot now points at a different physical page.
The net result will probably be rare corruption of disk file contents,
because viv.c will now be altering the page which the disk code was
recently using.
Thanks to Andrew Morton for pointing this.

The Coverity checker spotted that in usbvision_v4l2_read(), the variable
"frmx" is never assigned any value different from -1, but it's used an
an array index in "usbvision->frame[frmx]".
