Happy to do so, except that as far as I can tell it doesn't seem
appropriate for any existing header, and creating a new header for the
sole purpose of that one prototype seems excessive, particularly since
the function only has the one call from init/main.c.  Nonetheless, if
you'd like a new header created for that prototype, or you have a
suggestion for an existing header I missed that seems appropriate, let
me know and I'll respin the patch.
