That is why I am trying it get this through linux-next and/or dma-debug tree. I am open to suggestions on what is the best route. linux-next commit-id is: commit 6c9c6d6301287e369a754d628230fa6e50cdb74b I have another one that I sent to linux-next that fixes the dependency on get_dma_ops(): https://lkml.org/lkml/2012/11/3/219 Thanks, -- Shuah -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
