| |
The present do {} while stub's return cannot be checked, but the real HOTPLUG_CPU=y implementation of register_hotcpu_notifier() is int- returning. So let us make this stub consistent with the full version. Redefining this as such will also help us remove some #ifdef-ery elsewhere in kernel code, as shown in forthcoming patch.
