[PATCH 0/3] KVM: x86: Virtualize AMD CPUID faulting

[Jim Mattson]

AMD's "disable CPUID in usermode" feature is analogous to Intel's "CPUID
faulting" feature, but it is advertised and activated differently.  The AMD
feature is advertised via CPUID.80000021H:EAX.CpuidUserDis[bit 17] and
activated by setting HWCR.CpuidUserDis[bit 35].

Add virtualization support for the AMD feature.

  KVM: x86: Rename supports_cpuid_fault to supports_intel_cpuid_fault
  KVM: x86: Virtualize AMD CPUID faulting
