[PATCH 0/8] Adds CPU hot-plug support to Loongarch

[xianglai li <lixianglai@loongson.cn>]

Hello everyone, We refer to the implementation of ARM CPU
Hot-Plug to add GED-based CPU Hot-Plug support to Loongarch.

The first 4 patches are changes to the QEMU common code,
including adding GED support for CPU Hot-Plug, updating
the ACPI table creation process, and adding qdev_disconnect_gpio_out_named
and cpu_address_space_destroy interfaces to release resources
when CPU un-plug.

The last four patches are Loongarch architecture-related,
and the modifications include the definition of the hook
function related to the CPU Hot-(UN)Plug, the allocation
and release of CPU resources when CPU Hot-(UN)Plug,
the creation process of updating the ACPI table,
and finally the custom switch for the CPU Hot-Plug.

xianglai li (8):
  Update ACPI GED framework to support vcpu hot-(un)plug
  Update CPUs AML with cpu-(ctrl)dev change
  Introduced a new function to disconnect GPIO connections
  Introduce the CPU address space destruction function
  Adds basic CPU hot-(un)plug support for Loongarch
  Add support of *unrealize* for loongarch cpu
  Update the ACPI table for the Loongarch CPU
  Turn on CPU hot-(un)plug customization for loongarch
