[00/12] KVM: selftests: Add X86_PROPERTY_* magic

Message

Sean Christopherson Oct. 6, 2022, 12:51 a.m. UTC

Extend the X86_FEATURE_* magic to multi-bit values, which I'm
calling "properties" (feel free to suggest a better name).  The basic
concept, and even the core code, is the same, the difference is really
just one bit versus many bits.

The main goal is to move away from open coding CPUID checks, which
almost always end up needing a comment to explain what all the magic
numbers mean.
