This converts X86 and IA64 to use include/linux/dma-mapping.h. It's a bit large but pretty boring. The major change for X86 is converting 'int dir' to 'enum dma_data_direction dir' in DMA mapping operations. The major changes for IA64 is using map_page and unmap_page instead of map_single and unmap_single.
