Subject: [PATCH v3 09/11] KVM: selftests: Add x86 feature and properties for AMD PMU in processor.h
From: Jinrong Liang <cloudliang@...cent.com>
Add x86 feature and properties for AMD PMU so that tests don't have
to manually retrieve the correct CPUID leaf+register, and so that the
resulting code is self-documenting.
