[PATCH -tip 0/5] add generic dma-mappig.h

From: FUJITA Tomonori
Date: Thu May 07 2009 - 00:36:51 EST


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.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.
