Hi Guenter,

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>
