Is that sane? I thought a.out interpreters for ELF were a transitional
thing to cope with moving from a.out to ELF. Would anyone really do that
unless they had real a.out support in the first place?

I'm more inclined to believe that they just blindly copied <asm/user.h>
from i386 when the arch was created, and then later got
ARCH_SUPPORTS_AOUT defined for that arch because they had a

I suspect we could actually just remove <asm/a.out.h> for all
architectures except Alpha, x86, ARM and m68k. We'd probably have to
remove inclusions of <linux/a.out.h> from a few places in arch code, but
all of them will turn out to be gratuitous anyway.
