Pull KVM fixes from Radim Krčmář:
 "MIPS:
   - fix host kernel crashes when receiving a signal with 64-bit
     userspace

   - flush instruction cache on all vcpus after generating entry code

     (both for stable)

  x86:
   - fix NULL dereference in MMU caused by SMM transitions (for stable)

   - correct guest instruction pointer after emulating some VMX errors

   - minor cleanup"

* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
  KVM: VMX: remove duplicated declaration
  KVM: MIPS: Flush KVM entry code from icache globally
  KVM: MIPS: Don't clobber CP0_Status.UX
  KVM: x86: reset MMU on KVM_SET_VCPU_EVENTS
  KVM: nVMX: fix instruction skipping during emulated vm-entry
