Pull Xen fixes from Konrad Rzeszutek Wilk:
"This has two fixes. One is a security fix wherein we would spam the
kernel printk buffer if one of the guests was misbehaving. The other
is much tamer and it was us only checking for one type of error from
the IRQ subsystem (when allocating new IRQs) instead of for all of
them.
- Fix an IRQ allocation where we only check for a specific error (-1).
- CVE-2013-0231 / XSA-43. Make xen-pciback rate limit error messages
from xen_pcibk_enable_msi{,x}()"

Pull block layer updates from Jens Axboe:
"I've got a few bits pending for 3.8 final, that I better get sent out.
It's all been sitting for a while, I consider it safe.
It contains:
- Two bug fixes for mtip32xx, fixing a driver hang and a crash.
- A few-liner protocol error fix for drbd.
- A few fixes for the xen block front/back driver, fixing a potential
data corruption issue.
- A race fix for disk_clear_events(), causing spurious warnings. Out
of the Chrome OS base.
- A deadlock fix for disk_clear_events(), moving it to the a
unfreezable workqueue. Also from the Chrome OS base."
* 'for-linus' of git://git.kernel.dk/linux-block:
drbd: fix potential protocol error and resulting disconnect/reconnect
mtip32xx: fix for crash when the device surprise removed during rebuild
mtip32xx: fix for driver hang after a command timeout
block: prevent race/cleanup
block: remove deadlock in disk_clear_events
xen-blkfront: handle bvecs with partial data
llist/xen-blkfront: implement safe version of llist_for_each_entry
xen-blkback: implement safe iterator for the list of persistent grants
It is possible that the call to xen_allocate_irq_dynamic() returns negative
number other than -1.

The seccomp filters are currently built for the build host, not for the
machine that they are going to run on, but they are also built for with
the -m32 flag if the kernel is built for a 32 bit machine, both of which
seems rather odd.
It broke allyesconfig on my machine, which is x86-64, but building for
32 bit ARM, with this error message:
In file included from /usr/include/stdio.h:28:0,
from samples/seccomp/bpf-fancy.c:15:
/usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directory
because there are no 32 bit libc headers installed on this machine. We
should really be building all the samples for the target machine rather
than the build host, but since the infrastructure for that appears to be
missing right now, let's be a little bit smarter and not pass the '-m32'
flag to the HOSTCC when cross- compiling.

Commit 74349bcced ("checkpatch: add support for floating point
constants") added an unnecessary match variable that caused tests that
used a $Constant or $LvalOrFunc to have one too many matches.
This causes problems with usleep_range, min/max and other extended
tests.
Avoid using match variables in $Float.
Avoid using match variables in $Assignment too.

The macro for_each_memcg_cache_index contains a silly yet potentially
deadly mistake. Although the macro parameter is _idx, the loop tests
are done over i, not _idx.
This hasn't generated any problems so far, because all users use i as a
loop index. However, while playing with an extension of the code I
ended using another loop index and the compiler was quick to complain.
Unfortunately, this is not the kind of thing that testing reveals =(
