There isn't much else I can do with these. I can find no hardware for any
of them and no users. The code is broken.

I have learned that the 6730b and 6730s have different accelerometer
orientation, and have modified the driver accordingly (diff attached),
while dropping the wild guess for AMD based 6735 having the same
orientation as Intel based 6730 (this is not true for any other related
series/family, thus is not probable for 673x).

In the case where cpuidle_idle_call() returns before changing state due to
a need_resched(), it was returning with IRQs disabled.
The idle path assumes that the platform specific idle code returns with
interrupts enabled (although this too is undocumented AFAICT) and on ARM
we have a WARN_ON(!(irqs_disabled()) when returning from the idle loop, so
the user-visible effects were only a warning since interrupts were
eventually re-enabled later.
On x86, this same problem exists, but there is no WARN_ON() to detect it.
As on ARM, the interrupts are eventually re-enabled, so I'm not sure of
any actual bugs triggered by this. It's primarily a
correctness/consistency fix.
This patch ensures IRQs are (re)enabled before returning.

Allow csrows to properly initialize when the topology only has active
channels on 2 and 3. This new check allows proper detection and
initialization in this topology. Only checking the first mrt that
represented channels 0 and 1 is not sufficient.
I also fixed up the related debug information path. I can submit as a 2nd
patch if needed.

The i5400 EDAC driver has several bugs with chip-select row computation
which most likely lead to bugs in detailed error reporting. Attempts to
contact the authors have gone mostly unanswered so I am presenting my diff
here. I do not subscribe to lkml and would appreciate being kept in the
cc.
The most egregious problem was miscalculating the addresses of MTR
registers after register 0 by assuming they are 32bit rather than 16.
This caused the driver to miss half of the memories. Most motherboards
tend to have only 8 dimm slots and not 16, so this may not have been
noticed before.
Further, the row calculations multiplied the number of dimms several
times, ultimately ending up with a maximum row of 32. The chipset only
supports 4 dimms in each of 4 channels, so csrow could not be higher than
4 unless you use a row per-rank with dual-rank dimms. I opted to
eliminate this behavior as it is confusing to the user and the error
reporting works by slot and not rank. This gives a much clearer view of
memory by slot and channel in /sys.

The gpio_twl4030_probe() function calls gpio_twl4030_remove(), and the
former has __devinit, so the latter cannot use __devexit. Otherwise we
hit the section mismatch warning:
WARNING: drivers/gpio/built-in.o(.devinit.text+0x71a): Section mismatch
in reference from the function _gpio_twl4030_probe() to the function
.devexit.text:_gpio_twl4030_remove()
The function __devinit _gpio_twl4030_probe() references a function
__devexit _gpio_twl4030_remove().
This is often seen when error handling in the init function uses
functionality in the exit path.
The fix is often to remove the __devexit annotation of
_gpio_twl4030_remove() so it may be used outside an exit section.

CMD646 corrupts data on concurrent transfers on both channels when IDE SSD is
connected to one of the channels.
Setup that demonstrates this hardware bug: Ultra 5, onboard CMD646, rev 3.
/dev/hda is 8GB Seagate ST38410A in MWDMA2
/dev/hdd is 32GB SSD SiliconHardDisk in MWDMA2
- When reading /dev/hdd (for example with dd or fsck), reads from /dev/hda
are corrupted, there are twiddled single bits 1->0 and some full 32-bit
words corrupted, sometimes commands fail (which switches /dev/hda to
PIO mode but the corruptions happen even in PIO).
- Reads from /dev/hdd don't seem to be corrupted (i.e. fsck passes fine).
- When I connected normal rotating harddisk to /dev/hdd, there was no
corruption, so the corruption is something specific to SSD.
- I tried the same setup on a PCI card with CMD649 and saw no corruption.
This patch serializes the operation for CMD646 and 643 (I didn't test
CMD643 but it may have the same hw bug too because it's earlier design).
CMD649 is good. I don't know anything about CMD 648.

successfully drive a low-power, low-cost network adapter with USB ID
0a46:9000, based on a DM9000E chipset. As no device with this ID is yet
present in the kernel, I have created a patch that adds support for the device
to the dm9601 driver.

In mii monitor mode, bond_check_dev_link() calls the the ioctl
handler of slave devices. It stores the ndo_do_ioctl function
pointer to a static (!) ioctl variable and later uses it to call the
handler with the IOCTL macro.
If another thread executes bond_check_dev_link() at the same time
(even with a different bond, which none of the locks prevent), a
race condition occurs. If the two racing slaves have different
drivers, this may result in one driver's ioctl handler being
called with a pointer to a net_device controlled with a different
driver, resulting in unpredictable breakage.
Unless I am overlooking something, the "static" must be a
copy'n'paste error (?).

On SMP guests, reads from the ring might bypass used index reads. This
causes guest crashes because host writes to used index to signal ring
data readiness. Fix this by inserting rmb before used ring reads.

Commit f68d24082e22ccee3077d11aeb6dc5354f0ca7f1
in 2.6.32-rc1 broke requesting IRQs for per-VQ MSI-X vectors:
- vector number was used instead of the vector itself
- we try to request an IRQ for VQ which does not
have a callback handler
This is a regression that causes warnings in kernel log,
potentially lower performance as we need to scan vq list,
and might cause system failure if the interrupt
requested is in fact needed by another system.
This was not noticed earlier because in most cases
we were falling back on shared interrupt for all vqs.
The warnings often look like this:
virtio-pci 0000:00:03.0: irq 26 for MSI/MSI-X
virtio-pci 0000:00:03.0: irq 27 for MSI/MSI-X
virtio-pci 0000:00:03.0: irq 28 for MSI/MSI-X
IRQ handler type mismatch for IRQ 1

virtio net used to unlink skbs from send queues on error,
but ever since 48925e372f04f5e35fec6269127c62b2c71ab794
we do not do this. This causes guest data corruption and crashes
with vhost since net core can requeue the skb or free it without
it being taken off the list.
This patch fixes this by queueing the skb after successful
transmit.

Sometimes we will get the incorrect display modeline when parsing the detailed
timing in EDID. For example:
>hsync/vsync width is zero
>sync is beyond the blank.
So add the basic check for the detailed timing in EDID to avoid the incorrect
display modeline.

"b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported
in Bugzilla No. 14181; however, it introduced a new bug. Whenever the
radio switch was turned off, it was necessary to unload and reload
the driver for it to recognize the switch again.
This patch fixes both the original bug in #14181 and the bug introduced by
the previous patch. It must be stated, however, that if there is a BCM4306/3
with an rfkill switch (not yet proven), then the driver will need an
unload/reload cycle to turn the device back on.
