[GIT PULL] KVM updates for 2.6.26-rc9

[Avi Kivity]

Linus, please pull the kvm fixes from the repo and branch at:

  git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm.git kvm-updates-2.6.26

adding a missing memory clobber to kvm hypercalls, which cause failures
when running guests compiled with gcc 4.3.0, and fixing ioapic interrupt
redelivery under certain loads.

Shortlog, diffstat, and diff follow.

Anthony Liguori (1):
      x86: KVM guest: Add memory clobber to hypercalls

Mark McLoughlin (1):
      KVM: IOAPIC: Fix level-triggered irq injection hang
