Hi WingMan,

[auto build test ERROR on net/master]

config: arm-omap2plus_defconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 6.1.1-9) 6.1.1 20160705
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=arm 

Note: the linux-review/Grygorii-Strashko/net-ethernet-ti-cpts-switch-to-readl-writel_relaxed/20161204-010355 HEAD f938805dce662197c057c75ac67849f60da87c9f builds fine.
      It only hurts bisectibility.
