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':
   (.init.text+0x6742): undefined reference to
`acpi_indirectio_scan_init'

I believe the problem is in patch 4/7

config HISILICON_LPC
	bool "Support for ISA I/O space on Hisilicon Hip0X"
	depends on (ARM64 && ARCH_HISI) || COMPILE_TEST
                                         ^^^^^^^^^^^^

the COMPILE_TEST above allowing HISILICON_LPC also for other architectures. 
I think we can remove "|| COMPILE_TEST"...I will fix it in v10

Gab

+	select LOGIC_PIO
+	select INDIRECT_PIO
+	help
