void ioremap_add_map	(	phys_addr_t	phys,
		phys_addr_t	dma,
		phys_addr_t	size
	)

ioremap_add_map - add to the physical and DMA address conversion arrays : Process's view of the address of the start of the memory chunk : DMA address of the start of the memory chunk : Size, in bytes, of the chunk of memory

NOTE: It might be obvious, but the assumption is that all bytes have the same offset between the physical address and the DMA address.
