Unfortunately, this one doesn't get rid of the need to have the
exports, since the context switch code also needs mmu_psize_defs
and the associated objects. I think I have to come up with
a different change for that, but I don't mind putting the base
stuff into the kernel in the first place.

Mark has some changes to the file layout pending that will
impact this as well. I first need to see how that works out
together.

The patch to make the base non-modular is trivial, so we might
as well apply it now.
