Sometimes, there's a need to modify a lot of static keys or modify the same key multiple times in a loop. In that case, it seems more optimal to lock cpu_read_lock once and then call _cpuslocked() variants. The enable/disable functions are already exported, the refcounted counterparts however are not. Fix that to allow modules to save some cycles.
