Subject: Re: [PATCH v3 6/6] sparc64: Enable 64-bit DMA
Hi Tushar,
[auto build test ERROR on sparc/master]
[also build test ERROR on v4.9-rc3 next-20161028]
[cannot apply to sparc-next/master]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
[Suggest to use git(>=2.9.0) format-patch --base=<commit> (or --base=auto for convenience) to record what (public, well-known) commit your patch series was built on]
[Check https://git-scm.com/docs/git-format-patch for more information]
