However, since the default dma code for 32-bit (the dma_direct case) sets dma_length and length to the same thing, we should be able to use dma_length there as well. This gets rid of some 32-vs-64-bit ifdefs, and is needed by the swiotlb code which actually distinguishes between dma_length and length.
