[Qemu-devel] [PATCH 0/4] Fix kvm cpuid reporting

[Avi Kivity <avi@redhat.com>]

kvm supports an interface for reporting which cpuid features are supported.
Use it for trimming the cpu feature set reported to the guest.  This prevents,
for example, reporting NX to a guest when in fact we do not support it.

Avi Kivity (4):
  kvm: Add support for querying supported cpu features
  Make x86 cpuid feature names available in file scope
  Fix x86 feature modifications for features that set multiple bits
  kvm: Trim cpu features not supported by kvm
