From ddafddcfc78aab994cf95922befc54d98aaf371b Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sun, 2 Apr 2006 19:54:09 +1000 Subject: [PATCH] [PATCH] powerpc: Ensure runlatch is off in the idle loop Since external and decrementer interrupts set the runlatch on, we need to ensure its set off again in the idle loop. At the moment we dont turn it off in the inner loop.
