The function names for xsave[s]/xrstor[s] operations are horribly named and a permanent source of confusion. Rename: copy_xregs_to_kernel() to os_xsave() copy_kernel_to_xregs() to os_xrstor() These are truly low level wrappers around the actual instructions XSAVE[OPT]/XRSTOR and XSAVES/XRSTORS with the twist that the selection based on the available CPU features happens with an alternative to avoid conditionals all over the place and to provide the best performance for hot paths. The os_ prefix tells that this is the OS selected mechanism. No functional change.
