Commit e9fb7631 ("cpu-hotplug: introduce cpu_notify(), __cpu_notify(), cpu_notify_nofail()") also introduced this annoying warning: kernel/cpu.c:157: warning: 'cpu_notify_nofail' defined but not used when CONFIG_HOTPLUG_CPU wasn't set. So move that helper inside the #ifdef CONFIG_HOTPLUG_CPU region, and simplify it while at it. Signed-off-by:
