Not module "unplug" (I've never heard it called that before).  A module
with a module_init() but no module_exit() can only be added to a running
kernel, and never removed.  That's intentional behaviour.

However, if you're talking about hot-unplug, presumably you're talking
about _CPU_ hot-unplug, and that's something the code should definitely
handle irrespective of whether it's built-in or a module.

The two issues are entirely separate.
