SubjectRe: [PATCH 0/6] x86, fpu: cleanups, introduce non-lazy FPU restore for xsave
I have applied this to tip:x86/fpu, but I have also asked Suresh to
prepare a followon patch to decouple eager save from the existence of
the XSAVE instruction. It seems pretty clear that eager save is a net
benefit in the presence of the XSAVEOPT, but it isn't as clear for only
having XSAVE, as far as I can tell. Either way it would seem to be a
policy decision that is somewhat separate from the exact instruction.
