Bjoern A. Zeeb c39eefe715 LinuxKPI: implement dma_set_coherent_mask() ... Coherent is lower 32bit only by default in Linux and our only default dma mask is 64bit currently which violates expectations unless dma_set_coherent_mask() was called explicitly with a different mask. Implement coherent by creating a second tag, and storing the tags in the objects and use the tag from the object wherever possible. This currently does not update the scatterlist or pool (both could be converted but S/G cannot be MFCed as easily). There is a 2nd change embedded in the updated logic of linux_dma_alloc_coherent() to always zero the allocation as otherwise some drivers get cranky on uninialised garbage.
