I agree that it's probably negligible compared to the save/restore
code. If the x86 maintainers agree as well, I'll replace it with
cpu_has_xsave.

I asked Suresh to comment on this, since he wrote the original code. He
did confirm that the intent was to avoid a global memory reference.


Ok, so you're happy with the patch as is?
