2022-06-08	LoongArch: Fix the !CONFIG_SMP build	Huacai Chen	1	-1/+1
	1, We assume arch/loongarch/include/asm/smp.h be included in include/ linux/smp.h is valid and the reverse inclusion isn't. So remove the <linux/smp.h> in arch/loongarch/include/asm/smp.h. 2, arch/loongarch/include/asm/smp.h is only needed when CONFIG_SMP, and setup.c include it only because it need plat_smp_setup(). So, reorganize setup.c & smp.h, and then remove <asm/smp.h> in setup.c. 3, Fix cacheinfo.c and percpu.h build error by adding the missing header files when !CONFIG_SMP. 4, Fix acpi.c build error by adding CONFIG_SMP guards. 5, Move irq_stat definition from smp.c to irq.c and fix its declaration. 6, Select CONFIG_SMP for CONFIG_NUMA, similar as other architectures do.
