Series hw/arm/virt: Fix CPU's default NUMA node ID | expand

Commit Message

Gavin Shan April 20, 2022, 10:49 a.m. UTC
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 associate
    CPU with NUMA node when no default association isn't provided.

  * hw/core/machine-hmp-cmds.c::hmp_hotpluggable_cpus() to dump
    cluster-id.

nit: It doesn't really matter too much. But maybe clearer to read a 
sentence like
"machine_numa_finish_cpu_init() to record CPU slots with no NUMA mapping 
set."

Thanks,

I will modify this accordingly in v8. I prefer to hold v8 posting for
several days in case someone still have more comments on v7.
