From 045f9d22029e94d6609d46f8ee07c63f4693dfb3 Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Mon, 3 Mar 2008 14:13:05 -0300 Subject: [PATCH] x86: use remove_from_maps in cpu_disable it is already used in x86_64. In i386, it only removes from cpu_online_map Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar --- arch/x86/kernel/smpboot_32.c | 7 ++++++- arch/x86/kernel/smpboot_64.c | 8 +++----- 2 files changed, 9 insertions(+), 6 deletions(-) diff --git a/arch/x86/kernel/smpboot_32.c b/arch/x86/kernel/smpboot_32.c index a58ca7f..4939b3a 100644 --- a/arch/x86/kernel/smpboot_32.c +++ b/arch/x86/kernel/smpboot_32.c @@ -1041,6 +1041,11 @@ void __init native_smp_prepare_boot_cpu(void) } #ifdef CONFIG_HOTPLUG_CPU +static void __ref remove_cpu_from_maps(int cpu) +{ + cpu_clear(cpu, cpu_online_map); +} + int __cpu_disable(void) { cpumask_t map = cpu_online_map; @@ -1066,7 +1071,7 @@ int __cpu_disable(void) remove_siblinginfo(cpu); - cpu_clear(cpu, map); + remove_cpu_from_maps(cpu); fixup_irqs(map); /* It's now safe to remove this processor from the online map */ cpu_clear(cpu, cpu_online_map); diff --git a/arch/x86/kernel/smpboot_64.c b/arch/x86/kernel/smpboot_64.c index ca3a3c5..6509d3c 100644 --- a/arch/x86/kernel/smpboot_64.c +++ b/arch/x86/kernel/smpboot_64.c @@ -838,10 +838,9 @@ void __init native_smp_cpus_done(unsigned int max_cpus) } #ifdef CONFIG_HOTPLUG_CPU -static void __ref remove_cpu_from_maps(void) +static void __ref remove_cpu_from_maps(int cpu) { - int cpu = smp_processor_id(); - + cpu_clear(cpu, cpu_online_map); cpu_clear(cpu, cpu_callout_map); cpu_clear(cpu, cpu_callin_map); clear_bit(cpu, (unsigned long *)&cpu_initialized); /* was set by cpu_init() */ @@ -880,8 +879,7 @@ int __cpu_disable(void) remove_siblinginfo(cpu); /* It's now safe to remove this processor from the online map */ - cpu_clear(cpu, cpu_online_map); - remove_cpu_from_maps(); + remove_cpu_from_maps(cpu); fixup_irqs(cpu_online_map); return 0; } -- 2.7.4
