Hi zhichang.yuan,
[auto build test ERROR on linus/master]
[also build test ERROR on v4.12-rc2 next-20170525]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
url: https://github.com/0day-ci/linux/commits/Gabriele-Paoloni/LPC-legacy-ISA-I-O-support/20170526-033719
config: ia64-allmodconfig (attached as .config)
compiler: ia64-linux-gcc (GCC) 6.2.0
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=ia64
All errors (new ones prefixed by >>):
drivers/built-in.o: In function `lpc_host_io_setup':
>> hisi_lpc.c:(.text+0x252): undefined reference to `acpi_set_logic_pio_resource'
drivers/built-in.o: In function `acpi_scan_init':

I think we can remove "|| COMPILE_TEST"...I will fix it in v10 Gab + select LOGIC_PIO + select INDIRECT_PIO + help + Driver needed for some legacy ISA devices attached to Low-Pin-Count + on Hisilicon Hip0X SoC. > > --- > 0-DAY kernel test infrastructure Open Source Technology > Center > https://lists.01.org/pipermail/kbuild-all Intel > Corporation
