The hardware automatically disables further interrupts after each event

Prioritize synchronous signals over 'normal' signals
This makes sure that we pick the synchronous signals caused by a
processor fault over any pending regular asynchronous signals sent to
use by [t]kill().
This is not strictly required semantics, but it makes it _much_ easier
for programs like Wine that expect to find the fault information in the
signal stack.
Without this, if a non-synchronous signal gets picked first, the delayed
asynchronous signal will have its signal context pointing to the new
signal invocation, rather than the instruction that caused the SIGSEGV
or SIGBUS in the first place.
This is not all that pretty, and we're discussing making the synchronous
signals more explicit rather than have these kinds of implicit
preferences of SIGSEGV and friends. See for example
http://bugzilla.kernel.org/show_bug.cgi?id=15395
for some of the discussion. But in the meantime this is a simple and
fairly straightforward work-around, and the whole
if (x & Y)
x &= Y;
thing can be compiled into (and gcc does do it) just three instructions:
movq %rdx, %rax
andl $Y, %eax
cmovne %rax, %rdx
so it is at least a simple solution to a subtle issue.

To avoid potential problems with an empty /dev open /dev/console
from rootfs instead of waiting to mount our root filesystem and
mounting it there. This effectively guarantees that there will
be a device node, and it won't be on a filesystem that we will
ever unmount, so there are no issues with leaving /dev/console
open and pinning the filesystem.
This is actually more effective than automatically mounting
devtmpfs on /dev because it removes removes the occasionally
problematic assumption that /dev/console exists from the boot
code.
With this patch I was able to throw busybox on my /boot partition
(which has no /dev directory) and boot into userspace without
problems.
The only possible negative consequence I can think of is that
someone out there deliberately used did not use a character device
that is major 5 minor 2 for /dev/console. Does anyone know of a

fs: improve remount,ro vs buffercache coherency
Invalidate sb->s_bdev on remount,ro.
Fixes a problem reported by Jorge Boncompte who is seeing corruption
trying to snapshot a minix filesystem image. Some filesystems modify
their metadata via a path other than the bdev buffer cache (eg. they may
use a private linear mapping for their metadata, or implement directories
in pagecache, etc). Also, file data modifications usually go to the bdev
via their own mappings.
These updates are not coherent with buffercache IO (eg. via /dev/bdev)
and never have been. However there could be a reasonable expectation that
after a mount -oremount,ro operation then the buffercache should
subsequently be coherent with previous filesystem modifications.
So invalidate the bdev mappings on a remount,ro operation to provide a
coherency point.
The problem was exposed when we switched the old rd to brd because old rd
didn't really function like a normal block device and updates to rd via
mappings other than the buffercache would still end up going into its
buffercache. But the same problem has always affected other "normal"
block devices, including loop.

regulator: wm8400 - cleanup platform driver data handling
Driver data set by platform_set_drvdata() is for private use of
the driver currently bound to teh device and not for use by parent,
subsystem and anyone else.
