Both smp_call_function() and __smp_call_function_map() access cpu_online_map. Both functions run with preemption disabled which protects for cpus going offline. However new cpus can be added and therefore the cpu_online_map can change unexpectedly. So use the call_lock to protect against changes to the cpu_online_map in start_secondary() and all smp_call_* functions.
