dma-mapping: add asm-generic/dma-mapping-common.h
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 patch:
This header file provides some mapping function definitions that the users
of struct dma_map_ops can use.
