int ttm_mem_global_alloc	(	struct ttm_mem_global *	glob,
		uint64_t	memory,
		bool	no_wait,
		bool	interruptible
	)

Normal allocations of kernel memory are registered in all zones.

int ttm_mem_global_alloc_page	(	struct ttm_mem_global *	glob,
		struct page *	page,
		bool	no_wait,
		bool	interruptible
	)

Page allocations may be registed in a single zone only if highmem or !dma32.
