Hi Zubair,

[auto build test WARNING on tip/irq/core]

[cannot apply to linus/master linux/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]
