  sparc: add sync_single_for_device and sync_sg_for_device to struct dma_ops
  sparc: move the duplication in dma-mapping_{32|64}.h to dma-mapping.h
  p9100: use standard fields for framebuffer physical address and length
  leo: use standard fields for framebuffer physical address and length
  cg6: use standard fields for framebuffer physical address and length
  cg3: use standard fields for framebuffer physical address and length
