One of the reasons I've not done this is that it turns out that we
need to do the smp-on-up fixups on modules when running with certain
configs.  That means we need this function in other circumstances too.

It's probably going to be better to mark it with __maybe_unused than
to surround stuff with complex ifdefs.
