This version is only related with arch/loongarch and based on 6.9-rc4,
drop the patch "LoongArch: Move CONFIG_HAVE_SETUP_PER_CPU_AREA related
code to smp.c" to use the generic setup_per_cpu_areas() if CONFIG_NUMA
is not set.

The first 2 patches with detailed commit message are preparations for
patch #3.

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

Tiezhu Yang (3):
LoongArch: Modify acpi_parse_processor() for non-SMP
LoongArch: Modify ACPI S3 state function for non-SMP
LoongArch: Give chance to build under !CONFIG_SMP
