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 = arch/ia64/Kconfig | 1 + arch/ia64/include/asm/dma-mapping.h | 110 ++---------------- arch/x86/Kconfig | 1 + arch/x86/include/asm/dma-mapping.h | 174 +--------------------------- include/asm-generic/dma-mapping-common.h | 190 ++++++++++++++++++++++++++++++ lib/dma-debug.c | 82 ++++++++------ 6 files changed, 252 insertions(+), 306 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
