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>

+Do the ax25_list_lock, ax25_dev_lock, linkfail_lockreally, ax25_frag_lock and
+listen_lock have to be bh-safe?
+
+Do the netrom and rose locks have to be bh-safe?
+
+A device might be deleted after lookup in the SIOCADDRT ioctl but before it's
+being used.
+
+Routes to a device being taken down might be deleted by ax25_rt_device_down
+but added by somebody else before the device has been deleted fully.
+
+The ax25_rt_find_route synopsys is pervert but I somehow had to deal with
+the race caused by the static variable in it's previous implementation.
+
+Implement proper socket locking in netrom and rose.
+
+Check socket locking when ax25_rcv is sending to raw sockets. In particular
+ax25_send_to_raw() seems fishy. Heck - ax25_rcv is fishy.
+
+Handle XID and TEST frames properly.
