Subject: [PATCH v2 0/4] KVM: selftests: AMX test fix and cleanups
Date: Mon, 28 Nov 2022 22:57:31 +0000	[thread overview]
Message-ID: <20221128225735.3291648-1-seanjc@google.com> (raw)

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).
