[PATCH 2/4] register_ and unregister_memory_notifier should be global

[Andy Whitcroft <apw@shadowen.org>]

Both register_memory_notifer and unregister_memory_notifier are global
and declared so in linux.h.  Update the HOTPLUG specific definitions
to match.  This fixes a compile warning when HOTPLUG is enabled.
