[PATCH v2 0/4] KVM: selftests: AMX test fix and cleanups

From: Sean Christopherson
Date: Mon Nov 28 2022 - 17:57:46 EST


Fix a bug in the AMX test introduced by moving to kvm_cpu_has() for
X86_FEATURE_XFD, and clean up the related code. The fix and cleanups
all revolve around ARCH_REQ_XCOMP_GUEST_PERM impacting the output of
KVM_GET_SUPPORTED_CPUID, and thus causing problems for selftest's
caching of KVM's supported CPUID.

Lei Wang, I adjusted your Author and SOB tags to drop the comma, which I
think? violates that "use your real name" rule, and use formatting from
patches you've sent in the past[*]. Let me know if that's ok (or not).
