    Merge branch 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · ec0d7f18
    Linus Torvalds authored
    Pull fpu state cleanups from Ingo Molnar:
     "This tree streamlines further aspects of FPU handling by eliminating
      the prepare_to_copy() complication and moving that logic to
      arch_dup_task_struct().
    
      It also fixes the FPU dumps in threaded core dumps, removes and old
      (and now invalid) assumption plus micro-optimizes the exit path by
      avoiding an FPU save for dead tasks."
    
    Fixed up trivial add-add conflict in arch/sh/kernel/process.c that came
    in because we now do the FPU handling in arch_dup_task_struct() rather
    than the legacy (and now gone) prepare_to_copy().
    
    * 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
      x86, fpu: drop the fpu state during thread exit
      x86, xsave: remove thread_has_fpu() bug check in __sanitize_i387_state()
      coredump: ensure the fpu state is flushed for proper multi-threaded core dump
      fork: move the real prepare_to_copy() users to arch_dup_task_struct()
