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>

+Kernel driver emc6w201
+======================
+
+Supported chips:
+ * SMSC EMC6W201
+ Prefix: 'emc6w201'
+ Addresses scanned: I2C 0x2c, 0x2d, 0x2e
+ Datasheet: Not public
+
+Author: Jean Delvare <jdelvare@suse.de>
+
+
+Description
+-----------
+
+From the datasheet:
+
+"The EMC6W201 is an environmental monitoring device with automatic fan
+control capability and enhanced system acoustics for noise suppression.
+This ACPI compliant device provides hardware monitoring for up to six
+voltages (including its own VCC) and five external thermal sensors,
+measures the speed of up to five fans, and controls the speed of
+multiple DC fans using three Pulse Width Modulator (PWM) outputs. Note
+that it is possible to control more than three fans by connecting two
+fans to one PWM output. The EMC6W201 will be available in a 36-pin
+QFN package."
+
+The device is functionally close to the EMC6D100 series, but is
+register-incompatible.
+
+The driver currently only supports the monitoring of the voltages,
+temperatures and fan speeds. Limits can be changed. Alarms are not
+supported, and neither is fan speed control.
+
+
+Known Systems With EMC6W201
+---------------------------
+
+The EMC6W201 is a rare device, only found on a few systems, made in
+2005 and 2006. Known systems with this device:
+* Dell Precision 670 workstation
+* Gigabyte 2CEWH mainboard
