After applying above patch we can see "cpu_hotplug_done" and "cpu_hotplug_begin" functions in below file
root@android:/ #cat /sys/kernel/debug/tracing/available_filter_functions | grep cpu_hot
cpu_hotplug_done
cpu_hotplug_begin
cpu_hotplug_disable_before_freeze
cpu_hotplug_enable_after_thaw
cpu_hotplug_pm_callback

but when i executed the script to start cpu_hotplug_latency test . board produce below output and hugs. I did not see any kernel crash dump.
root@android:/data/hotplug # sh cpu_hotplug_latency.sh
