Hi Matthew, I love your patch! Yet something to improve: [auto build test ERROR on v5.4-rc8] [also build test ERROR on linux/master] [cannot apply to efi/next linus/master next-20191203] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Matthew-Garrett/Allow-disabling-PCI-busmastering-on-bridges-during-boot/20191203-084747 base: af42d3466bdc8f39806b26f593604fdc54140bcb config: arm-multi_v7_defconfig (attached as .config) compiler: arm-linux-gnueabi-gcc (GCC) 7.5.0 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 GCC_VERSION=7.5.0 make.cross ARCH=arm If you fix the issue, kindly add following tag Reported-by: kbuild test robot All errors (new ones prefixed by >>): In file included from drivers/firmware/efi/libstub/pci.c:12:0: drivers/firmware/efi/libstub/pci.c: In function 'efi_pci_disable_bridge_busmaster': >> arch/arm/include/asm/efi.h:53:33: error: 'sys_table_arg' undeclared (first use in this function); did you mean 'sys_table'?
