smp-core-2022-12-10: A small set of updates for CPU hotplug:
tagged this 10 Dec 16:34 
  - Prevent stale CPU hotplug state in the cpu_down() path which
    was detected by stress testing the sysfs interface

  - Ensure that the target CPU hotplug state for the boot CPU is
    CPUHP_ONLINE instead of the compile time init value CPUHP_OFFLINE.

  - Switch back to the original behaviour of warning when a CPU hotplug
    callback in the DYING/STARTING section returns an error code. Otherwise
    a buggy callback can leave the CPUs in an non recoverable state.
