- 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.

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.
