Masahiro Yamada 9d86b89c59 dma-mapping: move dma_map_(un)single() to <linux/dma-mapping.h> ... The implementation of dma_map_single() and dma_unmap_single() is exactly the same for all the architectures that support them. Factor them out to <linux/dma-mapping.h>, and make all drivers to include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>. If we need to differentiate them for some architectures, we can move the generic definitions to <asm-generic/dma-mapping.h>. Add some comments to the helpers. The concept is quite similar to the DMA-API of Linux kernel. Drivers are agnostic about what is going on behind the scene. Just call dma_map_single() before the DMA, and dma_unmap_single() after it.
