Just supporting 64bit DMA on 32bit hosts would probably only minor changes (like pushing the dma_mask flag a bit more out so that it is visible by scsi or ll_rw_blk), but 2.5 will probably also see more extensive changes for block drivers, like moving them to kiovecs. Your input would be probably welcome. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
