    It can sleep in map_new_virtual().

    The alternative is to use atomic kmaps. For this code, unless you can
    point to something concrete in the existing kernel which would benefit
    from passing an arbitrary number of scatterlists in, just code for the
    case of processing two at once (input & output).
