Subject: [PATCH 0/3] KVM: x86: Fix goofs with MONITOR/MWAIT quirk

Fix two bugs in the MONITOR/MWAIT selftest, and tweak the name of the
quirk (which isn't yet set in stone) to clarify that it only applies to
the #UD behavior, i.e. to reserve the right to correctly emulate #GP and
other faults in the future even if the quirk is enabled.

Sean Christopherson (3):
  KVM: selftests: Test MONITOR and MWAIT, not just MONITOR for quirk
  KVM: selftests: Provide valid inputs for MONITOR/MWAIT regs
  KVM: x86: Tweak name of MONITOR/MWAIT #UD quirk to make it #UD
    specific
