Since kernel commit ff58fa7f556c ("Documentation: Update CPU hotplug and move it to core-api"),
cpu_hotplug.txt has been removed. We should update it in here.

Is there a reason why you took out the reference to cpu-hotplug.txt
entirely rather than switching it to the rst file?

Because rst file doesn't have HOTPLUGGED off information and
ABI/testing/sysfs-devices-system-cpu file for offline  also doesn't have
cpu-hotplug.txt or rst file.

So I think removing it is better.
