History
Linus Torvalds 0a319ef75d 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.
