Message

Cleanups and a minor optimization to kvm_steal_time_set_preempted() that
were made possible by the switch to using a cache gfn->pfn translation.

Sean Christopherson (2):
  KVM: x86: Remove obsolete disabling of page faults in
    kvm_arch_vcpu_put()
  KVM: x86: Take KVM's SRCU lock only if steal time update is needed
