From 477bcae4c289a60f2303fbd4a3a875dcca647cf8 Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Wed, 6 Sep 2006 09:02:53 -0500 Subject: [PATCH] [POWERPC] Make function of pm_power_off consistent with x86 Allow the pm_power_off function variable in PPC to work as an override. This makes the function consistent with the other architectures and it allows generic poweroff operations (like those provided in IPMI systems) to work properly on PPC.
