#     Pull CPU hotplug updates from Thomas Gleixner:
#      "Updates for the SMP and CPU hotplug:
#     
#        - Remove DEFINE_SMP_CALL_CACHE_FUNCTION() which is a left over of the
#          original hotplug code and now causing trouble with the ARM64 cache
#          topology setup due to the pointless SMP function call.
#     
#          It's not longer required as the hotplug callbacks are guaranteed to
#          be invoked on the upcoming CPU.
#     
#        - Remove the deprecated and now unused CPU hotplug functions
#     
#        - Rewrite the CPU hotplug API documentation"
