Christoph Hellwig a20bb05837 dma-direct: add an explicit dma_direct_get_required_mask ... This is somewhat modelled after the powerpc version, and differs from the legacy fallback in use fls64 instead of pointlessly splitting up the address into low and high dwords and in that it takes (__)phys_to_dma into account.
