That's presumably a leftover from a.out days ... kill it.

Where did you find it?
I haven't seen in in mainline (noMMU kernel). It is in my MMU patches
which I want to send for review soon.
For noMMU I use CONFIG_BINFMT_FLAT (binfmt_flat.c) where I don't need
USE_ELF_CORE_DUMP
For MMU I use CONFIG_BINFMT_ELF (binfmt_elf.c) where USE_ELF_CORE_DUMP
make sense to me.
Can you give me some clue what you are trying to fix?
Thanks,
Michal

USE_ELF_CORE_DUMP is defined in arch/x86/include/*/elf.h (or sometimes
elf_{32,64}.h) on all architectures but microblaze.

USE_ELF_CORE_DUMP only comes into play if CONFIG_ELF_CORE is set, so in
the mmu example above. These two are in fact always checked together,
so not setting USE_ELF_CORE_DUMP is an obscure way to disable elf core
dumps despite CONFIG_ELF_CORE being set.
Currently all architectures but microblaze unconditionally define
USE_ELF_CORE_DUMP. The microblaze ommision seems like an error to
me, so let's kill this ifdef and make sure we are the same everywhere.

Yes, I came to a similar conclusion when I added get_dump_page():
#ifdef'ed it on CONFIG_ELF_CORE, but couldn't see the point of
USE_ELF_CORE_DUMP. (Though I missed the microblaze omission).

USE_ELF_CORE_DUMP was introduced in 2.6.11. Already back then all
architectures did define it unconditionally in <asm/elf.h> so there may
never have been any real use for it.
