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).
