Subject: include/linux/smp.h: define __smp_call_function_single for !CONFIG_SMP
This function was not needed until (watchdog: update watchdog_tresh
properly) which cannot use on_each_cpu unfortunately as
watchdog_nmi_enable relies on perf_event_alloc which is might sleep.
Export it as an alias to on_each_cpu for !CONFIG_SMP.
