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.

+	  the memory between 0xC0000000 and 0xD0000000 directly... everything

+	  sufficiently less than 0xE0000000 that the SDRAM does not intersect
+	  the I/O region.
+
+	  The base address must also be aligned such that the SDRAM controller

+choice
+	prompt "CPU Caching mode"
+	default FRV_DEFL_CACHE_WBACK
+	help
+	  This option determines the default caching mode for the kernel.
+
+	  Write-Back caching mode involves the all reads and writes causing
+	  the affected cacheline to be read into the cache first before being
+	  operated upon. Memory is not then updated by a write until the cache
+	  is filled and a cacheline needs to be displaced from the cache to
+	  make room. Only at that point is it written back.
+
+	  Write-Behind caching is similar to Write-Back caching, except that a
+	  write won't fetch a cacheline into the cache if there isn't already
+	  one there; it will write directly to memory instead.
+
+	  Write-Through caching only fetches cachelines from memory on a
+	  read. Writes always get written directly to memory. If the affected
+	  cacheline is also in cache, it will be updated too.
+
+	  The final option is to turn of caching entirely.
+
+	  Note that not all CPUs support Write-Behind caching. If the CPU on
+	  which the kernel is running doesn't, it'll fall back to Write-Back
+	  caching.

+	default GPREL_DATA_8
+	help
+	  This option controls what data, if any, should be placed in the GP
+	  relative data sections. Using this means that the compiler can
+	  generate accesses to the data using GR16-relative addressing which
+	  is faster than absolute instructions and saves space (2 instructions
+	  per access).
+
+	  However, the GPREL region is limited in size because the immediate
+	  value used in the load and store instructions is limited to a 12-bit
+	  signed number.
+
+	  So if the linker starts complaining that accesses to GPREL data are
+	  out of range, try changing this option from the default.
+
+	  Note that modules will always be compiled with this feature disabled
+	  as the module data will not be in range of the GP base address.

+	  Many PCI drivers require access to uncached memory for DMA device

+	  a fully featured MMU is available, this can be done through page
+	  table settings, but if not, a region has to be set aside and marked
+	  with a special DAMPR register.
+
+	  Setting this option causes uClinux to set aside a portion of the
+	  available memory for use in this manner. The memory will then be
+	  unavailable for normal kernel use.
