int io_reserve_memtype	(	resource_size_t	start,
		resource_size_t	end,
		unsigned long *	type
	)

io_reserve_memtype - Request a memory type mapping for a region of memory : start (physical address) of the region : end (physical address) of the region : A pointer to memtype, with requested type. On success, requested or any other compatible type that was available for the region is returned

On success, returns 0 On failure, returns non-zero
