Hi Jonathan, Today's linux-next merge of the jc_docs tree got a conflict in: Documentation/features/io/dma-api-debug/arch-support.txt between commit: 6e88628d03dd ("dma-debug: remove CONFIG_HAVE_DMA_API_DEBUG") from the dma-mapping tree and commit: 7156fc292850 ("Documentation/features: Refresh the arch support status files in place") from the jc_docs tree. I fixed it up (I just remobved the file like the former commit did) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell
