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 --- arch/i386/kernel/cpu/mcheck/therm_throt.c | 2 -- arch/i386/kernel/cpuid.c | 2 -- arch/i386/kernel/microcode.c | 2 -- arch/i386/kernel/msr.c | 2 -- 4 files changed, 8 deletions(-) (limited to 'arch/i386') diff --git a/arch/i386/kernel/cpu/mcheck/therm_throt.c b/arch/i386/kernel/cpu/mcheck/therm_throt.c index bad8b442070..065005c3f16 100644 --- a/arch/i386/kernel/cpu/mcheck/therm_throt.c +++ b/arch/i386/kernel/cpu/mcheck/therm_throt.c @@ -116,7 +116,6 @@ static __cpuinit int thermal_throttle_add_dev(struct sys_device *sys_dev) return sysfs_create_group(&sys_dev->kobj, &thermal_throttle_attr_group); } -#ifdef CONFIG_HOTPLUG_CPU static __cpuinit void thermal_throttle_remove_dev(struct sys_device *sys_dev) { return sysfs_remove_group(&sys_dev->kobj, &thermal_throttle_attr_group); @@ -153,7 +152,6 @@ static struct notifier_block thermal_throttle_cpu_notifier = { .notifier_call = thermal_throttle_cpu_callback, }; -#endif /* CONFIG_HOTPLUG_CPU */ static __init int thermal_throttle_init_device(void) { diff --git a/arch/i386/kernel/cpuid.c b/arch/i386/kernel/cpuid.c index ab0c327e79d..23b2cc748d4 100644 --- a/arch/i386/kernel/cpuid.c +++ b/arch/i386/kernel/cpuid.c @@ -167,7 +167,6 @@ static int cpuid_device_create(int i) return err; } -#ifdef CONFIG_HOTPLUG_CPU static int cpuid_class_cpu_callback(struct notifier_block *nfb, unsigned long action, void *hcpu) { unsigned int cpu = (unsigned long)hcpu; @@ -187,7 +186,6 @@ static struct notifier_block __cpuinitdata cpuid_class_cpu_notifier = { .notifier_call = cpuid_class_cpu_callback, }; -#endif /* !CONFIG_HOTPLUG_CPU */ static int __init cpuid_init(void) { diff --git a/arch/i386/kernel/microcode.c b/arch/i386/kernel/microcode.c index 23f5984d065..972346604f9 100644 --- a/arch/i386/kernel/microcode.c +++ b/arch/i386/kernel/microcode.c @@ -703,7 +703,6 @@ static struct sysdev_driver mc_sysdev_driver = { .resume = mc_sysdev_resume, }; -#ifdef CONFIG_HOTPLUG_CPU static __cpuinit int mc_cpu_callback(struct notifier_block *nb, unsigned long action, void *hcpu) { @@ -726,7 +725,6 @@ mc_cpu_callback(struct notifier_block *nb, unsigned long action, void *hcpu) static struct notifier_block mc_cpu_notifier = { .notifier_call = mc_cpu_callback, }; -#endif static int __init microcode_init (void) { diff --git a/arch/i386/kernel/msr.c b/arch/i386/kernel/msr.c index a773f776c9e..7763c67ca28 100644 --- a/arch/i386/kernel/msr.c +++ b/arch/i386/kernel/msr.c @@ -250,7 +250,6 @@ static int msr_device_create(int i) return err; } -#ifdef CONFIG_HOTPLUG_CPU static int msr_class_cpu_callback(struct notifier_block *nfb, unsigned long action, void *hcpu) { @@ -271,7 +270,6 @@ static struct notifier_block __cpuinitdata msr_class_cpu_notifier = { .notifier_call = msr_class_cpu_callback, }; -#endif static int __init msr_init(void) { -- cgit v1.2.3
