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.

Thanks, it fixes it.

I'm using one from upstream svn head (= tree that will become gcc 4.3).

That's Matt's "break all no-MMU architectures in swapops.h" regression 
for which a patch is already floating around.

This is a problem for all nommu architectures. The patch fixed all four
of them.

[PATCH] Add pgtable_t to nommu architectures.
    
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
    
The pte_fn_t in include/linux/mm.h make it necessary for all
architecture to define a pgtable_t type, even those that do
not have an mmu.
