Does the patch below fixes the problem? I tried to cross compile for
m68knommu but it seems like you need a special m68k compiler to get it
compile all the way through. With the patch it did fail with a different
error, so I assume it is fixed. The problem is that the pgtable_t is
simply missing for m68knommu, I must have overlooked a reject for one of
the constant regenerations of the patch to keep up with upstream. Sorry
about that.
