    Linus Torvalds authored
    Pull x86/xsave changes from Peter Anvin:
     "This is a patchset to support the XSAVES instruction required to
      support context switch of supervisor-only features in upcoming
      silicon.
    
      This patchset missed the 3.16 merge window, which is why it is based
      on 3.15-rc7"
