I can not see why you handle IP22, IP32, Cobalt as so "special". There are many other platforms which supports 64-bit and uses CKSEG0 load address (well, actually all 64-bit platforms except for IP27). So I think Franck's approach, which enables -msym32 and defines KBUILD_64BIT_SYM32 automatically if load-y was CKSEG0, is better. Are there any problem with his patchset? --- Atsushi Nemoto
