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
