Subject: [PATCH 01/16] qapi/machine.json: Add cluster-id
RH-Author: Gavin Shan <gshan@redhat.com>
RH-MergeRequest: 86: hw/arm/virt: Fix the default CPU topology
RH-Commit: [1/6] 44d7d83008c6d28485ae44f7cced792f4987b919 (gwshan/qemu-rhel-9)
RH-Bugzilla: 2041823

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2041823
This adds cluster-id in CPU instance properties, which will be used
by arm/virt machine. Besides, the cluster-id is also verified or
dumped in various spots:
* hw/core/machine.c::machine_set_cpu_numa_node() to associate
CPU with its NUMA node.
* hw/core/machine.c::machine_numa_finish_cpu_init() to record
CPU slots with no NUMA mapping set.
* hw/core/machine-hmp-cmds.c::hmp_hotpluggable_cpus() to dump
cluster-id.
