This will potentially break a bunch of things that assume the only valid values of direction are NONE, TO_DEVICE, FROM_DEVICE, or BOTH (e.g., include/linux/dma-mapping.h:valid_dma_direction()). > or > > - Add new functions dma_map_single_flushing(), > dma_map_sg_flushing() and dma_map_page_flushing() that are > defined to be the same as the non-flushing variants except on > Altix.

Looks like we need to harness the collective power of lkml. Better hope everyone isn't distracted by the flamewar-du-jour.
