commit: 35391f5df33ee69e0d2ba0b794bac62712fe2020 [4/30] mips: Do not include linux/irqdomain.h from asm/irq.h
config: mips-xway_defconfig (attached as .config)
compiler: mips-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 35391f5df33ee69e0d2ba0b794bac62712fe2020
        # save the attached .config to linux build tree
