The booter doesn't know the size. You see, right now the user first loads the
kernel using whatever means s/he wants, then runs my booter. The booter doesn't
currently know the kernel size. You want to give my users an extra hassle of
stuffing the kernel size in a register before starting my booter so the latter
can know it. Why? What's wrong with the other alternative (my yesterday's
patch) which would keep me happy, keep my users happy, and keep the rest of the
Linux/PPC community happy because it doesn't break anything and is completely

So how about applying that patch then?

I've heard a different plan, namely having one (1) register, no "magic", point
to bi_recs. That's what I want.

Where is that someplace? I don't see how you can come up with anything other
than something tied to aspects of the vmlinux ELF image, which I have already
shown to be not good.
