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@xxxxxxxxxx>
    
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.
