Merge git://git.kernel.org/pub/scm/virt/kvm/kvm 

Pull a couple of KVM fixes from Avi Kivity:
 "One is an adjustment for an irq layer change that affected device
  assignment, the other a one-liner ppc fix."

* git://git.kernel.org/pub/scm/virt/kvm/kvm:
  powerpc/kvm: Fix "PR" KVM implementation of H_CEDE
  KVM: Fix device assignment threaded irq handler
