Some drivers call dma_inv_range() on buffers, on arm these buffers must be cache line aligned. This patch introduces a generic dma_alloc, dma_free. Archs can implement in their own functions in "asm/dma.h" and add a: #define dma_alloc dma_alloc #define dma_free dma_free On all other archs the generic versions, which translate into xmalloc and free are used.
