parent[PATCH] i386: avoid checking for cpu gone when CONFIG_HOTPLUG_CPU not defined (diff)
[PATCH] i386: replace spin_lock_irqsave with spin_lock
IRQ is already disabled through local_irq_disable(). So spin_lock_irqsave() can be replaced with spin_lock(). Signed-off-by: Hisashi Hifumi <hifumi.hisashi@oss.ntt.co.jp> Signed-off-by: Andi Kleen <ak@suse.de> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
