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.

++Mediatek 65xx/67xx/81xx sysirq
+
+Mediatek SOCs sysirq support controllable irq inverter for each GIC SPI
+interrupt.
+
+Required properties:
+- compatible: should be one of:
+	"mediatek,mt8173-sysirq"
+	"mediatek,mt8135-sysirq"
+	"mediatek,mt8127-sysirq"
+	"mediatek,mt6795-sysirq"
+	"mediatek,mt6592-sysirq"
+	"mediatek,mt6589-sysirq"
+	"mediatek,mt6582-sysirq"
+	"mediatek,mt6580-sysirq"
+	"mediatek,mt6577-sysirq"
+- interrupt-controller : Identifies the node as an interrupt controller
+- #interrupt-cells : Use the same format as specified by GIC in
+  Documentation/devicetree/bindings/arm/gic.txt
+- interrupt-parent: phandle of irq parent for sysirq. The parent must
+  use the same interrupt-cells format as GIC.
+- reg: Physical base address of the intpol registers and length of memory
+  mapped region.
+
+Example:
+	sysirq: interrupt-controller@10200100 {
+		compatible = "mediatek,mt6589-sysirq", "mediatek,mt6577-sysirq";
+		interrupt-controller;
+		#interrupt-cells = <3>;
+		interrupt-parent = <&gic>;
+		reg = <0 0x10200100 0 0x1c>;
+	};
