Pull KVM fixes from Radim Krčmář:
 "PPC:
   - Fix a bug causing occasional machine check exceptions on POWER8
     hosts (introduced in 4.16-rc1)

  x86:
   - Fix a guest crashing regression with nested VMX and restricted
     guest (introduced in 4.16-rc1)

   - Fix dependency check for pv tlb flush (the wrong dependency that
     effectively disabled the feature was added in 4.16-rc4, the
     original feature in 4.16-rc1, so it got decent testing)"
