OK. I did wonder about that, which is why I did it in a separate patch.

Actually, I think we can drop the preceding patch too -- it's not
necessary to fix the regression in 2.6.26, and dhowells suggests that we
might still want to use ARCH_SUPPORTS_AOUT, by making BINFMT_AOUT depend
on it instead of that hard-coded list of architectures.

If we do that, then ARCH_SUPPORTS_AOUT would need to be defined on a
different set of architectures to the ones it's currently defined on --
so I don't really want to go there before 2.6.26. I'll push just the
parts which were included in the mail I just sent.

Why _are_ there architectures which define ARCH_SUPPORTS_AOUT and have
<asm/a.out.h> but don't support binfmt_aout, anyway? How does that make
sense?
