There is nothing that disallows gpio-keys to share it's IRQ line
w/ other drivers. Make it use IRQF_SHARED in request_irq().
An example of other driver with which I'd like to share IRQ line
for GPIO buttons is ledtrig-gpio.

If user presses keys while i8042 is being initialized there is a chance
that keyboard data will be mistaken for results of Read Control Register
command causing futher troubles. Work around this issue by reading CTR
several times and stop when we get matching results.

When nilfs flushes out dirty data to reduce memory pressure, creation
of checkpoints is wrongly postponed. This bug causes irregular
checkpoint creation especially in small footprint systems.
To correct this issue, a timer for the checkpoint creation has to be
continued if a log writer does not create a checkpoint.
This will do the correction.

Bruno Prémont and Dunphy, Bill noticed me that NILFS will certainly
hang on ARM-based targets.
I found this was caused by an underflow of dirty pages counter. A
b-tree cache routine was marking page dirty without adjusting page
account information.
This fixes the dirty page accounting leak and resolves the hang on
arm-based targets.

The driver always ends a read with a STOP condition which
breaks subsequent I2C reads/writes in the same transaction as
these expect to do a repeated START(ReSTART).
This will also help I2C multimaster as the bus will not be released
after the first read, but when the whole transaction ends.

The controller can't do anything else before it actually generates START/STOP.
So we check busy bit to make sure START/STOP is successfully finished.
If we don't check busy bit, START/STOP may fail on some fast CPUs.

one of the problems manifests itself as a warning:

commit 211a4d12abf86fe0df4cd68fc6327cbb58f56f81
Author: Johannes Berg <johannes@sipsolutions.net>

cfg80211: sme: deauthenticate on assoc failure
introduced a potential NULL pointer dereference that
some people have been hitting for some reason -- the
params.bssid pointer is not guaranteed to be non-NULL
for what seems to be a race between various ways of
reaching the same thing.
While I'm trying to analyse the problem more let's
first fix the crash. I think the real fix may be to
avoid doing _anything_ if it ended up being NULL, but
right now I'm not sure yet.
I think
http://bugzilla.kernel.org/show_bug.cgi?id=14342
might also be this issue.

[IA64] Squeeze ticket locks back into 4 bytes.
This reverts commit d0646f7b63, as
requested by Eric Sandeen.
It can basically cause an ext4 filesystem to miss recovery (and thus get
mounted with errors) if the journal checksum does not match.
Quoth Eric:
"My hand-wavy hunch about what is happening is that we're finding a
bad checksum on the last partially-written transaction, which is
not surprising, but if we have a wrapped log and we're doing the
initial scan for head/tail, and we abort scanning on that bad
checksum, then we are essentially running an unrecovered filesystem.
But that's hand-wavy and I need to go look at the code.
We lived without journal checksums on by default until now, and at
this point they're doing more harm than good, so we should revert
the default-changing commit until we can fix it and do some good
power-fail testing with the fixes in place."
See

for all the gory details.
