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
