Following is a pseudo patch (a script + a patch) that merges
the include files for m68k and m68knommu in one place at:

The script was written by Arnd and I added a few modifications.
Thanks! I'll take a closer look when I'll find some spare time...
I have used the following include guard:
#ifdef __uClinux__
#include "atomic_no.h"
#else
#include "atomic_mm.h"
#endif
gcc -E -dM for the two compilers revealed that this was the
only symbol that differed.
I think you can share a toolchain for m68k and m68knommu, at least for the
kernel (I used my plain m68k toolchain when experimenting with m68knommu for
Amiga).
With the above construct we do the "right thing" also for
headers exported to userspace.
But actually none of the headers using the above are
subject for export at the moment so we could use a
CONFIG_ symbol for the same.
So I prefer to just check CONFIG_MMU.
