arch/m68k/include/asm/ is not shipped, (arch/m68k/include/uapi/asm/ is).
However, arch/m68k/include/asm/ is shared with the whole tree, while
only the core code under arch/m68k/ needs these definitions.

There is (are) definitely (an) opportunit{y,ies} for moving more stuff
around (from <asm/...> to "...", more extern declarations in C files, ...).
Not to mention the more substantial rework...
But Linux/m68k^WRome wasn't built in a decade neither... ;-)

And TBH, I also went for the "minimum amount of work" ;-)
(which didn't work out that well, yet another rabbit hole, as usual...).

Gr{oetje,eeting}s,
