Hmm. Can you check if making it be #define PHYSMEM_END ((phys_addr_t)-1) fixes things for you? That said, it would probably be even better if we got rid of these games entirely, and m68k just defined MAX_PHYSMEM_BITS instead. Maybe as a config option, since I assume it's going to be either 24 or 32 depending on CPU (or are there other choices? I used to know the old m68k, but...) Linus
