[Avi Kivity <avi@qumranet.com>]

Linus,

Please pull from the repository and branch

  git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm.git for-linus

to receive the pending kvm updates for 2.6.22.  The changes increase
the range of guests we support, improve performance, fix various bugs,
and improve the userspace interface.

      KVM: Handle partial pae pdptr
      KVM: Use slab caches to allocate mmu data structures
      KVM: Retry sleeping allocation if atomic allocation fails
      KVM: SVM: Report hardware exit reason to userspace instead of dmesg
      KVM: Handle guest page faults when emulating mmio
      KVM: VMX: Reduce unnecessary saving of host msrs
      KVM: VMX: Don't switch 64-bit msrs for 32-bit guests
      KVM: Fold drivers/kvm/kvm_vmx.h into drivers/kvm/vmx.c
      KVM: VMX: Only save/restore MSR_K6_STAR if necessary
      KVM: Per-vcpu statistics

Dor Laor (3):
      KVM: Fix guest register corruption on paravirt hypercall
      KVM: Use the generic skip_emulated_instruction() in hypercall code
