[Jörn Engel]

Derived from a patch Arjan sent around.

The cheapest, fastest and most reliable components of a computer
system are those that aren't there.
-- Gordon Bell, DEC labratories

Next step for inter_module removal.  This patch makes the code
conditional on its last users and shrinks the kernel binary for the
huge majority of people.
