[PATCH v2 3/3] powerpc/powernv: Reboot when requested by firmware

From: Joel Stanley
Date: Wed Apr 01 2015 - 03:05:39 EST


Use orderly_reboot so userspace will to shut itself down via the reboot
path. This is required for graceful reboot initiated by the BMC, such
as when a user uses ipmitool to issue a 'chassis power cycle' command.
