Pull CPU hotplug updates from Thomas Gleixner:

 - Initialize the per-CPU structures during early boot so that the state
   is consistent from the very beginning.

 - Make the virtualization hotplug state handling more robust and let
   the core bringup CPUs which timed out in an earlier attempt again.

 - Make the x86/xen CPU state tracking consistent on a failed online
   attempt, so a consecutive bringup does not fall over the inconsistent
   state.

* tag 'smp-core-2022-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  cpu/hotplug: Initialise all cpuhp_cpu_state structs earlier
  cpu/hotplug: Allow the CPU in CPU_UP_PREPARE state to be brought up again.
  x86/xen: Allow to retry if cpu_initialize_context() failed.
