They would need a bit more work to be usable on m68k. I have a basic
patch to use DISCONTIGMEM for m68k. There I have the problem that I have
to deal with almost random memory configurations. So converting a
virtual/physical address or pfn into a section number can't use a
compile time constant, instead an offset/shift is calculated at boot
time and patched into the kernel.

bye, Roman
