Hi, very cool rework! So far I didn't notice any problems while testing.

Buy anyway I wanted to ask if you thought about including the cpuid_deps[] or
cpuid_dependent_features[] into the new cpuid API ecosystem?

Or if not (since this patchset is quite long already :b ), then do you have any
idea where best it could fit in? During discussion on [1] you mentioned the
feature depenedency should be encoded in x86-cpuid-db. I assume you meant it
would need to be first patched into there, then parsed by Kconfig?

(resending the email as the in-reply-to got lost somehow and I wanted to correct
top posting)
