Hi Guenter, > The problem seems to have been introduced with changes made by Christoph > Hellwig, coming in through Andrew's tree. Copying them here for comments.
xtensa doesn't use the generic dma map implementation, so it shouldn't include dma-mapping-common.h anywhere, and in my tree it doesn't. Can you do a git-grep for dma-mapping-common.h on the tree that you see this error on? Nothing but arch/*/include/asm/dma-mapping.h should include it. In my tree it's all fine: Documentation/DMA-API-HOWTO.txt: can use include/linux/asm-generic/dma-mapping-common.h. It's a arch/alpha/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/arm/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/arm64/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/h8300/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/hexagon/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/ia64/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/microblaze/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/mips/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/openrisc/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/powerpc/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/s390/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/sh/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/sparc/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/tile/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/unicore32/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> arch/x86/include/asm/dma-mapping.h:#include <asm-generic/dma-mapping-common.h> -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
