[PATCH 0/4] x86: Feature check cleanup

Posted by Andrew Cooper 11 months, 3 weeks ago

This builds on the work from "[PATCH 0/6] x86: Introduce MSR_ARCH_CAPS into
featuresets" and is just cleanup to feature handling.

No functional change.

  x86/cpufeature: Rework {boot_,}cpu_has()
  x86/vtx: Remove opencoded MSR_ARCH_CAPS check
  x86/tsx: Remove opencoded MSR_ARCH_CAPS check
  x86/spec-ctrl: Remove opencoded MSR_ARCH_CAPS check
