    Subject[PULL REQUEST] DMA-mapping framework redesign preparation patches
    Hi Stephen,

    Our patches with DMA-mapping framework redesign proposal have been
    hanging for over a month with just a few comments. We would like to go
    further in the development, but first I would like to ask You to give
    them a try in the linux-next kernel.

    For everyone interested in this patch series, here is the relevant
    thread: https://lkml.org/lkml/2011/12/23/97

    If there are any problems with our git tree, please contact Marek
    Szyprowski <m.szyprowski@samsung.com> or alternatively Kyungmin Park
    <kyungmin.park@samsung.com>.
