[Yu-cheng Yu]

** Based on tip/master **

This is Part 1 of previous 13 XSAVES patches. Break it down to
smaller series. There are no code changes; only minor fixes in
the titles.

Fenghua Yu (3):
  x86/fpu/xstate: Define and use fpu_user_xstate_size
  x86/fpu/xstate: Rename xstate_size to fpu_kernel_xstate_size to
    distinguish from fpu_user_xstate_size
  x86/fpu/xstate: Keep init_fpstate.xsave.header.xfeatures as zero for
    init optimization

Yu-cheng Yu (1):
  x86/fpu/xstate: Copy xstate registers directly to signal frame when
    compacted format is in use
