What I meant by "both" was that part of asm/adb_iop.h could be absorbed by 
drivers/macintosh.adb-iop.c and the rest by asm/mac_iop.h. (And some of it 
could be tossed out.) I suspect that much of arch/m68k/include/asm could 
get the same treatment. But I doubt that there is any pay off, because the 
headers rarely change where they relate to hardware characteristics.
