-/* To avoid some locking problems, we hard allocate certain PILs
- * for SMP cross call messages that must do a etrap/rtrap.
- *
- * A local_irq_disable() does not block the cross call delivery, so
- * when SMP locking is an issue we reschedule the event into a PIL
- * interrupt which is blocked by local_irq_disable().
- *
- * In fact any XCALL which has to etrap/rtrap has a problem because
- * it is difficult to prevent rtrap from running BH's, and that would
- * need to be done if the XCALL arrived while %pil==15.
