From 4138d65333fa8961714441ed40229ea8cbeaf7e5 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Fri, 6 Aug 2010 03:28:19 +0000 Subject: powerpc: Inline ppc64_runlatch_off I'm sick of seeing ppc64_runlatch_off in our profiles, so inline it into the callers. To avoid a mess of circular includes I didn't add it as an inline function.
