    I think that the best hope is a combination of Roman's module depends
    work (based on Kai's "everything which is a module is trivial", and
    Stephen and my first depends hack) and explicit depends.

    Linkage ordering doesn't work in general, for things like "I want to
    be initialized before the non-boot cpus have come up", but for
    non-core code it's simple.

    Yes, it'll slow the build by a few seconds: but if the linker ever
    decides not to preserve ordering, we'll need it. My original shell
    script is suboptimal but we *don't* want the kernel build relying on
    libbfd.

    Roman and I will come up with something and send it to you later this
    week.

    Thanks!
    Rusty.
