[PATCH] ppc64: call idle_task_exit with irqs disabled
This patch is from Nathan Lynch <ntl@pobox.com>.
Seeing this very occasionally during cpu hotplug testing:
Badness in slb_flush_and_rebolt at arch/ppc64/mm/slb.c:52
Call Trace:

idle_task_exit can result in a call to slb_flush_and_rebolt, which
must not be called with interrupts enabled. Make the call with
interrupts disabled.
