Merge git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Marcelo Tosatti: "KVM bug fixes, including a SVM interrupt injection regression fix, MIPS and ARM bug fixes" * git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: MIPS: Enable after disabling interrupt KVM: MIPS: Fix trace event to save PC directly KVM: SVM: fix interrupt injection (apic->isr_count always 0) KVM: emulate: fix CMPXCHG8B on 32-bit hosts KVM: VMX: fix build without CONFIG_SMP arm/arm64: KVM: Add exit reaons to kvm_exit event tracing ARM: KVM: Fix size check in __coherent_cache_guest_page
