Done. I also took the occasion to rename
KVM_X86_QUIRK_VMCS12_ALLOW_FREEZE_IN_SMM because not having a verb was

More boringly, I changed one of the entries in the tag description like this:

- Fix cases where CPUID mitigation features were incorrectly marked as
available whenever the kernel used scattered feature words for them.
