MIPS: Loongson64: Select SMP in Kconfig to avoid build error
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.
