Subject: [PATCH 0/2] KVM: x86: Clean up MP_STATE transitions

Introduce a generic setter, kvm_set_mp_state(), and use that to ensure that
pv_unhalted is cleared on all transitions to KVM_MP_STATE_RUNNABLE.

Jim Mattson (2):
  KVM: x86: Introduce kvm_set_mp_state()
  KVM: x86: Clear pv_unhalted on all transitions to
    KVM_MP_STATE_RUNNABLE
