We unified x86 and IA64's handling of multiple dma mapping operations (struct dma_map_ops in linux/dma-mapping.h) so we can remove duplication in their arch/include/asm/dma-mapping.h.
This patchset adds include/asm-generic/dma-mapping-common.h that provides some generic dma mapping function definitions for the users of struct dma_map_ops. This enables us to remove about 100 lines. This also enables us to easily add CONFIG_DMA_API_DEBUG support, which only x86 supports for now. The 4th patch adds CONFIG_DMA_API_DEBUG support to IA64 by adding only 8 lines.
This is against tip/master since tip has some changes to arch/x86/include/asm/dma-mapping.h.
The changes since the first version are
- fixed a bug that dma_attrs is not passed properly (thanks to Arnd Bergmann).
- used a new name, dma-mapping-common.h, instead of dma-mapping.h (suggested by Arnd Bergmann).
- added Joerg's Acked-by
