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>

+ * To put things into perspective, consider sparc64 with a few PCI controllers.
+ * Each type would have an own structure, with instances related one to one.
+ * We have only pcic on sparc, but we want to be compatible with sparc64 pbm.h.
+ * All three represent different abstractions.

+ * pbm - Arch-specific view of a PCI bus (sparc or sparc64)
+ * pcic - Chip-specific information for PCIC.
