Hi Ma,

[auto build test ERROR on tip/irq/core]
[also build test ERROR on v4.5-rc3 next-20160212]
[if your patch is applied to the wrong git tree, please drop us a note to help improving the system]

url:    https://github.com/0day-ci/linux/commits/MaJun/irqchip-Add-support-for-Hisilicon-mbigen-v1-chip/20160214-101957
config: arm64-defconfig (attached as .config)
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=arm64 

Note: the linux-review/MaJun/irqchip-Add-support-for-Hisilicon-mbigen-v1-chip/20160214-101957 HEAD 9acb433456cd9671c97c0eeb1ccca8cc3b986081 builds fine.
      It only hurts bisectibility.
