SubjectRe: [PATCH 01/13] perf/core: Add perf_arch_regs and mask to perf_regs structure
Hi Madhavan,

[auto build test WARNING on tip/perf/core]
[also build test WARNING on v4.8-rc4 next-20160825]
[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]
