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>

+.TH "CPUPOWER\-FREQUENCY\-SET" "1" "0.1" "" "cpupower Manual"
+.SH "NAME"
+.LP
+cpupower frequency\-set \- A small tool which allows to modify cpufreq settings.
+.SH "SYNTAX"
+.LP
+cpupower [ \-c cpu ] frequency\-set [\fIoptions\fP]
+.SH "DESCRIPTION"
+.LP
+cpupower frequency\-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed" all the time.
+.SH "OPTIONS"
+.LP
+.TP
+\fB\-d\fR \fB\-\-min\fR <FREQ>
+new minimum CPU frequency the governor may select.
+.TP
+\fB\-u\fR \fB\-\-max\fR <FREQ>
+new maximum CPU frequency the governor may select.
+.TP
+\fB\-g\fR \fB\-\-governor\fR <GOV>
+new cpufreq governor.
+.TP
+\fB\-f\fR \fB\-\-freq\fR <FREQ>
+specific frequency to be set. Requires userspace governor to be available and loaded.
+.TP
+\fB\-r\fR \fB\-\-related\fR
+modify all hardware-related CPUs at the same time
+.TP
+.SH "REMARKS"
+.LP
+By default values are applied on all cores. How to modify single core
+configurations is described in the cpupower(1) manpage in the \-\-cpu option section.
+.LP
+The \-f FREQ, \-\-freq FREQ parameter cannot be combined with any other parameter.
+.LP
+FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (frequency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).
+.LP
+On Linux kernels up to 2.6.29, the \-r or \-\-related parameter is ignored.
