[also build test ERROR on v4.9-rc8 next-20161206]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url:    https://github.com/0day-ci/linux/commits/Abel-Vesa/arm-Add-livepatch-support/20161207-074210
config: arm-allmodconfig (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

        make.cross ARCH=arm 

Note: the linux-review/Abel-Vesa/arm-Add-livepatch-support/20161207-074210 HEAD 49113edc744f38a682a4afa9e904384bb00f2988 builds fine.
      It only hurts bisectibility.
