Merge tag 'x86-fpu-2020-06-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 FPU updates from Ingo Molnar:
"Most of the changes here related to 'XSAVES supervisor state' support,
which is a feature that allows kernel-only data to be automatically
saved/restored by the FPU context switching code.
CPU features that can be supported this way are Intel PT, 'PASID' and
CET features"
