    So basically this is a copy of arch/m68knommu/lib/checksum.c, with some
    checkpatch.pl fixes but without the sparse fixes?
    Furthermore, it's just plain C, so maybe we need a common one that can
    be shared by multiple archs?

    when I'm talking to journalists I just say "programmer" or something like that.
