[PATCH v2 0/3] KVM: x86: Update HWCR virtualization

[Jim Mattson <jmattson@xxxxxxxxxx>]

Allow HWCR.McStatusWrEn to be cleared once set, and allow
HWCR.TscFreqSel to be set from userspace.

v1 -> v2: KVM no longer sets HWCR.TscFreqSel
          HWCR.TscFreqSel can be cleared from userspace
          Selftest modified accordingly

  KVM: x86: Allow HWCR.McStatusWrEn to be cleared once set
  KVM: x86: Virtualize HWCR.TscFreqSel[bit 24]
  KVM: selftests: Test behavior of HWCR
