The patch below fixes all compile-issues on m68k, except when compiling for
Sun-3.

include/asm-generic/tlb.h now includes <asm/pgalloc.h>, which includes
<asm/sun3_pgalloc.h>. But the last file needs tlb_remove_page(), which is
defined in include/asm-generic/tlb.h

Do you really need <asm/pgalloc.h> in include/asm-generic/tlb.h? If yes, can it
be moved down, after the definition of tlb_remove_page()?
