m68k has two or three levels of page tables and can use appropriate
pgtable-nopXd and folding of the upper layers.

Replace usage of include/asm-generic/4level-fixup.h and explicit
definitions of __PAGETABLE_PxD_FOLDED in m68k with
include/asm-generic/pgtable-nopmd.h for two-level configurations and with
include/asm-generic/pgtable-nopud.h for three-lelve configurations and
adjust page table manipulation macros and functions accordingly.

This one was messed up by linux-next changes in arch/m68k/mm/kmap.c.
Can you please take a look?

Can you please elaborate what was the problem?

The patch applies cleanly to v5.4-rc6-mmots-2019-11-08-16-23 (from
github.com/hnaz/linux-mm) and all the page table traversals in
arch/m68k/mm/kmap.c look Ok.

I've build atari_defconfig and it boots fine on aranym.
 

You mean due to the rename and move of __iounmap() to __free_io_area()
in commit aa3a1664285d0bec ("m68k: rename __iounmap and mark it static")?

Commit 42d6c83d6180f800 ("m68k: mm: use pgtable-nopXd instead of
4level-fixup") in next-20191108 looks good to me.

Gr{oetje,eeting}s,
