    Nevermind, I confused it with a different problem that I'm running into
    with randconfig builds:

    arm-linux-gnueabi-nm: 'arch/arm/boot/compressed/../../../../vmlinux':
    No such file

    I applied your patch, and it did not happen for a couple of randconfigs,
    but that is now back. So I did not test the bug you are fixing, and the
    thing that I thought you fixed is still there.
