Please describe how this changes modpost behaviour.
Something like: "we're currently not checking for references into
meminit and meminitdata when CONFIG_HOTPLUG=y, which may cause us to
fail to notice incorrect references.". But I don't think that's
correct. So what *is* wrong with the current code?
