  x86, fpu: Also check fpu_lazy_restore when use_eager_fpu (2015-02-17 18:58:34 +0100)

----------------------------------------------------------------
A round of updates to the FPU maze from Oleg and Rik. It should make the
code a bit more understandable/readable/streamlined and a preparation
for more cleanups and improvements in that area.

Oleg Nesterov (3):
      x86, fpu, unlazy_fpu: Don't reset thread.fpu_counter
      x86, fpu: unlazy_fpu: don't do __thread_fpu_end() if use_eager_fpu()
      x86, fpu: Kill save_init_fpu(), change math_error() to use unlazy_fpu()

Rik van Riel (5):
      x86, fpu: Move lazy restore functions up a few lines
      x86, fpu: Introduce task_disable_lazy_fpu_restore helper
      x86, fpu: Use an explicit if/else in switch_fpu_prepare
      x86, fpu: Use task_disable_lazy_fpu_restore() helper
      x86, fpu: Also check fpu_lazy_restore when use_eager_fpu
