This has _nothing_ to do with the boot ABI. The boot ABI for 2.4 hasn't
changed, as far as I can remember anyhow. The plan for 2.5 is to come
up with and agree upon once and for all (and it seems that it's been
mostly done too). The question I asked is why do you want to make a
vmlinux that runs on large groups of totally unrelated, save for a CPU
family, mostly, group of computers.
If someone really wanted, they could put 8xx and 4xx into this mess too,
with some complex asm, and have 1 kernel that boots on 4xx/6xx/7xx/74xx/8xx.
I doubt it'd be useful, but it could be done.
