From 087a4eb55971dfcc8df18312faf9393d0a479f3a Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Thu, 14 Oct 2010 12:10:30 +0900 Subject: [PATCH] stopmachine: Define __stop_machine when CONFIG_STOP_MACHINE=n Define dummy __stop_machine() function even when CONFIG_STOP_MACHINE=n. This getcpu-required version of stop_machine() will be used from poke_text_smp().
