Hi Scott,

[auto build test ERROR on linus/master]
[also build test ERROR on v4.11-rc6]
[cannot apply to arm64/for-next/core]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

config: arm64-defconfig (attached as .config)
compiler: aarch64-linux-gnu-gcc (Debian 6.1.1-9) 6.1.1 20160705
reproduce:
        wget https://raw.githubusercontent.com/01org/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/Andrea-Reale/Memory-hotplug-support-for-arm64-complete-patchset/20170412-022242 HEAD bffdda51b562ca7bb9baf7642e14c8d03d44602d builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
