    ... which is not to say of course we can't do both, dev_archdata could
    have a list of struct dma_mapping_ops instead of (or in addition to) a
    struct dma_mapping_ops pointer. If space was at a premium we could
    even multiplex both on the same pointer by using one of the low bits
    to select between them.

    Cheers,
    Muli
