Merge Linus master into drm-next

The merge is clean, but the arm build fails afterwards,
due to API changes in the regulator tree.

I've included the patch into the merge to fix the build.

+Broadcom BCM3380-style Level 1 / Level 2 interrupt controller
+
+This interrupt controller shows up in various forms on many BCM338x/BCM63xx
+chipsets.  It has the following properties:
+
+- outputs a single interrupt signal to its interrupt controller parent
+
+- contains one or more enable/status word pairs, which often appear at
+  different offsets in different blocks
+
+- no atomic set/clear operations
+
+Required properties:
+
+- compatible: should be "brcm,bcm3380-l2-intc"
+- reg: specifies one or more enable/status pairs, in the following format:
+  <enable_reg 0x4 status_reg 0x4>...
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: specifies the number of cells needed to encode an interrupt
+  source, should be 1.
+- interrupt-parent: specifies the phandle to the parent interrupt controller
+  this one is cascaded from
+- interrupts: specifies the interrupt line in the interrupt-parent controller
+  node, valid values depend on the type of parent interrupt controller
+
+Optional properties:
+
+- brcm,irq-can-wake: if present, this means the L2 controller can be used as a
+  wakeup source for system suspend/resume.
+
+Example:
+
+irq0_intc: interrupt-controller@10000020 {
+	compatible = "brcm,bcm3380-l2-intc";
+	reg = <0x10000024 0x4 0x1000002c 0x4>,
+	      <0x10000020 0x4 0x10000028 0x4>;
+	interrupt-controller;
+	#interrupt-cells = <1>;
+	interrupt-parent = <&cpu_intc>;
+	interrupts = <2>;
+};
