Subject: [PATCH v2 1/4 RESEND] MIPS: Loongson64: Select SMP in Kconfig to avoid build error
Date: Sun, 11 Oct 2020 07:47:51 +0800 [thread overview]
Message-ID: <1602373674-4579-2-git-send-email-yangtiezhu@loongson.cn> (raw)
In-Reply-To: <1602373674-4579-1-git-send-email-yangtiezhu@loongson.cn>
In the current code, CONFIG_SMP can be set as N by user on the Loongson
platform, then there exists the following build error under !CONFIG_SMP:
CC arch/mips/kernel/asm-offsets.s
In file included from ./include/linux/gfp.h:9:0,
from ./include/linux/xarray.h:14,
from ./include/linux/radix-tree.h:18,
from ./include/linux/fs.h:15,
from ./include/linux/compat.h:17,
from arch/mips/kernel/asm-offsets.c:12:
./include/linux/topology.h: In function 'numa_node_id':
./include/linux/topology.h:119:2: error: implicit declaration of function 'cpu_logical_map' [-Werror=implicit-function-declaration]
return cpu_to_node(raw_smp_processor_id());
^
cc1: some warnings being treated as errors
scripts/Makefile.build:117: recipe for target 'arch/mips/kernel/asm-offsets.s' failed
make[1]: *** [arch/mips/kernel/asm-offsets.s] Error 1
Select SMP in Kconfig to avoid the above build error and then remove
CONFIG_SMP=y in loongson3_defconfig.
