commit: 1136731f544e664ab2990fe615c049ead0479b6d [17/39] irqchip/gic-v3-its: Generalize LPI configuration
config: arm64-defconfig (attached as .config)
compiler: aarch64-linux-gnu-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
        git checkout 1136731f544e664ab2990fe615c049ead0479b6d
        # save the attached .config to linux build tree
        make.cross ARCH=arm64 

Note: the arm-platforms/kvm-arm64/gicv4-wip HEAD 1bca4673c546185e9812e8479900eca8a3ca9c33 builds fine.
      It only hurts bisectibility.
