Subject: [PATCH v3 0/4] Give chance to build under !CONFIG_SMP for LoongArch

The changes of irqchip have been merged into the irq/core branch of tip.

https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=42a7d887664b
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=a64003da0ef8

This version is only related with arch/loongarch and based on 6.9-rc3,
the first 3 patches with detailed commit message are preparations for
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

Tiezhu Yang (4):
  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
