These changes are the raw update to linux-4.4.6-rt14. Kernel sources

are taken from kernel.org, and rt patch from the rt wiki download page.

During the rebasing, the following patch collided:

Force tick interrupt and get rid of softirq magic(I70131fb85).

Collisions have been removed because its logic was found on the
source already.

+Required properties:
+
+- compatible:	Should be "brcm,bcm2835-mbox"
+- reg:		Specifies base physical address and size of the registers
+- interrupts:	The interrupt number
+		  See bindings/interrupt-controller/brcm,bcm2835-armctrl-ic.txt
+- #mbox-cells:	Specifies the number of cells needed to encode a mailbox
+		  channel. The value shall be 0, since there is only one
+		  mailbox channel implemented by the device.

+Example:
+
+mailbox: mailbox@7e00b800 {
+	compatible = "brcm,bcm2835-mbox";
+	reg = <0x7e00b880 0x40>;
+	interrupts = <0 1>;
