• 9bbafce2e   sh: Fix occasional FPU register corruption under preempt. ... Browse Code »

  Presently with preempt enabled there's the possibility to be preempted
  after the TIF_USEDFPU test and the register save, leading to bogus
  state post-__switch_to(). Use an explicit preempt_disable()/enable()
  pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86
  change.
