3  * Contiguous Memory Allocator for DMA mapping framework
9  * Contiguous Memory Allocator
11  *   The Contiguous Memory Allocator (CMA) makes it possible to
12  *   allocate big contiguous chunks of memory after the system has
18  *   IO map support and require contiguous blocks of memory to
161  * dma_contiguous_reserve() - reserve area(s) for contiguous memory handling
213  * dma_contiguous_reserve_area() - reserve custom contiguous area
226  * If @fixed is true, reserve contiguous area at exactly @base.  If false,
240 	/* Architecture specific contiguous memory fixup. */  in dma_contiguous_reserve_area()
248  * dma_alloc_from_contiguous() - allocate pages from contiguous area
255  * device specific contiguous memory area if available or the default
276  * It returns false when provided pages do not belong to contiguous area and
294  * dma_alloc_contiguous() - allocate contiguous pages
299  * tries to use device specific contiguous memory area if available, or it
304  * global area as the addresses within one page are always contiguous, so
352  * cma_release returns false when provided pages do not belong to contiguous
