How about just applying patches 1-5 and 7-8, and deferring the actual removal of cpu_has_xfeatures() to the next cycle?
Yeah, just did that, will push out tip/master after some testing.
XFEATURE_MASK_OPMASK is just part of the AVX-512 state and it will be implied by X86_FEATURE_AVX512F.
Right, I wouldn't mind if we zap those cpu_has_xfeatures() in perf/core now
but then it'll need to merge x86/fpu... so perhaps waiting for the next cycle
is better.
I'm putting it on my todo, unless you wanna do it. :-)
Thx.
