has been removed from the -mm tree. Its filename is

This patch was dropped because it was folded into cpu-hotplug-make-register_cpu_notifier-init-time-only.patch
------------------------------------------------------
Subject: cpu-hotplug-make-register_cpu_notifier-init-time-only-fix fix
From: Chandra Seetharaman <sekharan@xxxxxxxxxx>
cpufreq_register_driver() has to made available at all time (not init
only). Hence, we should be using hotplug version of the cpu notifier
register/unregister function instead of the _init time only_ version.
