[....]

The whole "v2", "v3", "v4" etc naming seems to be some crazy glibc
artifact and is stupid and needs to die.

It has no relevance to anything. Please do *not* introduce that
mind-fart into the kernel sources.

I have no idea who came up with the "microarchitecture levels"
garbage, but as far as I can tell, it's entirely unofficial, and it's
a completely broken model.

There is a very real model for microarchitectural features, and it's
the CPUID bits. Trying to linearize those bits is technically wrong,
since these things simply aren't some kind of linear progression.

And worse, it's a "simplification" that literally adds complexity. Now
instead of asking "does this CPU support the cmpxchgb16 instruction?",
the question instead becomes one of "what the hell does 'v3' mean
again?"

So no. We are *NOT* introducing that idiocy in the kernel.
