Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> We lose all the git history this way and it's not good. We should apply another opnfv project repo in future. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+ bool "DEVFREQ-Event device Support"
+ help
+ The devfreq-event device provide the raw data and events which
+ indicate the current state of devfreq-event device. The provided
+ data from devfreq-event device is used to monitor the state of
+ device and determine the suitable size of resource to reduce the
+ wasted resource.
+
+ The devfreq-event device can support the various type of events
+ (e.g., raw data, utilization, latency, bandwidth). The events
+ may be used by devfreq governor and other subsystem.
