I can change it to be an AMD/HYGON check... although, I'll have to check to see if any (very) early use of the function will work with that.

We can always change it later if really needed. It is just that I'm not a fan of such "preemptive" changes.

At a minimum, the check in arch/x86/kernel/head64.c will have to be changed or removed. I'll take a closer look.

Yeah, sme_me_mask, already discussed on IRC.
