Subject: [PATCH 0/2] KVM: VMX: CR0/CR4 guest/host masks cleanup

Fix a bug where CR4.TSD isn't correctly marked as being possibly owned by
the guest in the common x86 macro, then clean up the mess that made the
bug possible by throwing away VMX's mix of duplicate code and open coded
tweaks.  The lack of a define for the guest-owned CR0 bit has bugged me
for a long time, but adding another define always seemed ridiculous.

  KVM: x86: Mark CR4.TSD as being possibly owned by the guest
  KVM: VMX: Use KVM_POSSIBLE_CR*_GUEST_BITS to initialize guest/host
    masks
