Since the enabling and disabling of IRQs within preempt_schedule_irq() is contained in a need_resched() loop, we don't need the outer arch code loop. We seem to be looping back somewhere much higher than the usual preempt/need_resched checks, but AFAICT we would just branch to 'rtrap_no_irq_enable' and then back to 'to_kernel', which is a need_resched() loop with a few extra steps.
