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>

+config PNPBIOS
+ bool "Plug and Play BIOS support"
+ depends on ISA && X86
+ default n
+ ---help---
+ Linux uses the PNPBIOS as defined in "Plug and Play BIOS
+ Specification Version 1.0A May 5, 1994" to autodetect built-in
+ mainboard resources (e.g. parallel port resources).
+
+ Some features (e.g. event notification, docking station information,
+ ISAPNP services) are not currently implemented.
+
+ If you would like the kernel to detect and allocate resources to
+ your mainboard devices (on some systems they are disabled by the
+ BIOS) say Y here. Also the PNPBIOS can help prevent resource
+ conflicts between mainboard devices and other bus devices.
+
+ Note: ACPI is expected to supersede PNPBIOS some day, currently it
+ co-exists nicely. If you have a non-ISA system that supports ACPI,
+ you probably don't need PNPBIOS support.
+
+config PNPBIOS_PROC_FS
+ bool "Plug and Play BIOS /proc interface"
+ depends on PNPBIOS && PROC_FS
+ ---help---
+ If you say Y here and to "/proc file system support", you will be
+ able to directly access the PNPBIOS. This includes resource
+ allocation, ESCD, and other PNPBIOS services. Using this
+ interface is potentially dangerous because the PNPBIOS driver will
+ not be notified of any resource changes made by writing directly.
+ Also some buggy systems will fault when accessing certain features
+ in the PNPBIOS /proc interface (e.g. "boot" configs).
+
+ See the latest pcmcia-cs (stand-alone package) for a nice set of
+ PNPBIOS /proc interface tools (lspnp and setpnp).
+
+ Unless you are debugging or have other specific reasons, it is
+ recommended that you say N here.
