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.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
