Linus Torvalds 894909f95a - Do not hold fpregs lock when inheriting FPU permissions because the

fpregs lock disables preemption on RT but fpu_inherit_perms() does
 spin_lock_irq(), which, on RT, uses rtmutexes and they need to be
 preemptible.

   fpregs lock disables preemption on RT but fpu_inherit_perms() does
   spin_lock_irq(), which, on RT, uses rtmutexes and they need to be
