 /* To avoid some locking problems, we hard allocate certain PILs
  * for SMP cross call messages that must do a etrap/rtrap.
  *
- * A cli() 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 cli().
+ * 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

  *
  * 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
