commit: 8af4c6c076d0f4c8469f3aab34aa93d638306d2b [12/13] irqchip/gic-v3-its: Register LPI tables with EFI config table
config: arm64-defconfig (attached as .config)
compiler: aarch64-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 8af4c6c076d0f4c8469f3aab34aa93d638306d2b
        # save the attached .config to linux build tree
        GCC_VERSION=7.2.0 make.cross ARCH=arm64 

Note: the arm-platforms/irq/gicv3-kdump HEAD 8bc67dad68a8d35bd9186eb4782df953da664a66 builds fine.
      It only hurts bisectibility.
