From 02316067852187b8bec781bec07410e91af79627 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 6 Dec 2006 20:38:17 -0800 Subject: [PATCH] hotplug CPU: clean up hotcpu_notifier() use There was lots of #ifdef noise in the kernel due to hotcpu_notifier(fn, prio) not correctly marking 'fn' as used in the !HOTPLUG_CPU case, and thus generating compiler warnings of unused symbols, hence forcing people to add #ifdefs. the compiler can skip truly unused functions just fine: text data bss dec hex filename 1624412 728710 3674856 6027978 5bfaca vmlinux.before 1624412 728710 3674856 6027978 5bfaca vmlinux.after [akpm@osdl.org: topology.c fix] Signed-off-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/base/topology.c | 2 -- drivers/cpufreq/cpufreq.c | 2 -- 2 files changed, 4 deletions(-) (limited to 'drivers') diff --git a/drivers/base/topology.c b/drivers/base/topology.c index 3d12b85b0962..067a9e8bc377 100644 --- a/drivers/base/topology.c +++ b/drivers/base/topology.c @@ -108,7 +108,6 @@ static int __cpuinit topology_add_dev(unsigned int cpu) return rc; } -#ifdef CONFIG_HOTPLUG_CPU static void __cpuinit topology_remove_dev(unsigned int cpu) { struct sys_device *sys_dev = get_cpu_sysdev(cpu); @@ -136,7 +135,6 @@ static int __cpuinit topology_cpu_callback(struct notifier_block *nfb, } return rc ?
