    This causes some unpleasantness in the ia64 build with CONFIG_IA32_SUPPORT=y

    and lots more like this. Suddenly having elf.h included in a lot of
    the ia32 compat
    files is the root problem.

    What does syscalls.h really need to pull in at this point ... is there
    a way for it to get it without pulling in so much extra stuff?
