Merge tag 'kvm-x86-selftests-6.4' of https://github.com/kvm-x86/linux into HEAD
KVM selftests, and an AMX/XCR0 bugfix, for 6.4:
- Don't advertise XTILE_CFG in KVM_GET_SUPPORTED_CPUID if XTILE_DATA is
not being reported due to userspace not opting in via prctl()
- Overhaul the AMX selftests to improve coverage and cleanup the test
- Misc cleanups
