This version is only related with arch/loongarch and based on 6.9-rc3,

patch #4.

Tested with the following configs:
(1) CONFIG_NUMA=n, CONFIG_SMP=n
(2) CONFIG_NUMA=n, CONFIG_SMP=y
(3) CONFIG_NUMA=y, CONFIG_SMP=n (not allowed due to NUMA select SMP)
(4) CONFIG_NUMA=y, CONFIG_SMP=y

LoongArch: Move CONFIG_HAVE_SETUP_PER_CPU_AREA related code to smp.c
LoongArch: Refactor get_acpi_id_for_cpu() related code
LoongArch: Save and restore PERCPU_BASE_KS for ACPI S3 state
LoongArch: Give chance to build under !CONFIG_SMP
