[GIT PULL] (xen) stable/for-linus-3.4-rc4-tag

[Konrad Rzeszutek Wilk]

Hey Linus,

Please pull this git tag

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-linus-3.4-rc4-tag

which has some really good bug-fixes. Some of these had been in existence
since the 2.6.27 days, some since 3.0 - and some due to new features
added in v3.4.

The one that is most interesting is David's one - in the low-level assembler
code we had be checking events needlessly. With his patch now we do it
when the appropriate flag is set - with the added benefit that we can process
events faster. Stefano's is fixing a mistake where the Linux IRQ numbers
were ACK-ed instead of the Xen IRQ, resulting in missing interrupts. The
other ones are bootup related that can show up on various hardware.

Please pull!
