Hi AKASHI,

[also build test ERROR on v4.13 next-20170908]
[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/AKASHI-Takahiro/kexec-add-kexec_file_load-support/20170910-143930
base:   https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git for-next/core
config: arm64-allmodconfig (attached as .config)
compiler: aarch64-linux-gnu-gcc (Debian 6.1.1-9) 6.1.1 20160705
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/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/AKASHI-Takahiro/kexec-add-kexec_file_load-support/20170910-143930 HEAD caf976acefa5a78ad88489581c66b98cbc8f91fa builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
