Heiko Carstens 4c2241fd42 [S390] percpu: implement arch specific irqsafe_cpu_ops ... Implement arch specific irqsafe_cpu ops. The arch specific ops do not disable/enable interrupts since that is an expensive operation. Instead we disable preemption and perform a compare and swap loop. Since on server distros (the ones we care about) preemption is disabled the preempt_disable()/preempt_enable() pair is a nop. In the end this code should be faster than the generic one.
