Oleg Nesterov df24fb859a x86, fpu: __restore_xstate_sig()->math_state_restore() needs preempt_disable() 
Add preempt_disable() + preempt_enable() around math_state_restore() in
__restore_xstate_sig(). Otherwise __switch_to() after __thread_fpu_begin()
can overwrite fpu->state we are going to restore.
