Pull CPU hotplug updates from Thomas Gleixner:
 "A small set of updates for CPU hotplug:

   - 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"
