Also update some other details.

	/*

	 * A new process must start with interrupts closed in 2.5,

	 * because this is how Mingo's scheduler works (see schedule_tail

	 * and finish_arch_switch). If we do not do it, a timer interrupt hits

	 * before we unlock, attempts to re-take the rq->lock, and then we die.

	 * A new process must start with interrupts disabled, see schedule_tail()

	 * and finish_task_switch(). (If we do not do it and if a timer interrupt

	 * hits before we unlock and attempts to take the rq->lock, we deadlock.)

	 *

	 * Thus, kpsr |= PSR_PIL.
