Maybe add a comment here why you can't use cpu_has (yet).

So that could be alleviated by moving this function *after*
init_scattered_cpuid_features(). Then you can simply do *cpu_has().

Hmmm... I still need the ebx value from the CPUID instruction to
calculate the proper reduction in physical bits, so I'll still need
to make the CPUID call.

Thanks,

Also, I'm not sure why we're checking CPUID for the SME feature when we
have sme_get_me_mask() et al which have been setup much earlier...
