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.
