[PATCH] x86_64: Fix fast check in safe_smp_processor_id The APIC ID returned by hard_smp_processor_id can be beyond NR_CPUS and then overflow the x86_cpu_to_apic[] array. Add a check for overflow. If it happens then the slow loop below will catch. Bug pointed out by Doug Thompson Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
