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>

+ ---help---
+ The 2.4 kernel changed the kernel start address from 0x310000
+ to 0x810000 to make room for the Wildfire's larger SRM console.
+ Recent consoles on Titan and Marvel machines also require the
+ extra room.
+
+ If you're using aboot 0.7 or later, the bootloader will examine the
+ ELF headers to determine where to transfer control. Unfortunately,
+ most older bootloaders -- APB or MILO -- hardcoded the kernel start
+ address rather than examining the ELF headers, and the result is a
+ hard lockup.
+
+ Say Y if you have a broken bootloader. Say N if you do not, or if
+ you wish to run on Wildfire, Titan, or Marvel.
