Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm

Pull ARM updates from Russell King:
 "Here's the updates for ARM for this merge window, which cover quite a
  variety of areas.

  There's a bunch of patch series from Will tackling various bugs like
  the PROT_NONE handling, ASID allocation, cluster boot protocol and
  ASID TLB tagging updates.

  We move to a build-time sorted exception table rather than doing the
  sorting at run-time, add support for the secure computing filter, and
  some updates to the perf code.  We also have sorted out the placement
  of some headers, fixed some build warnings, fixed some hotplug
  problems with the per-cpu TWD code."

+* ARM CPUs binding description
+
+The device tree allows to describe the layout of CPUs in a system through
+the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
+defining properties for every cpu.
+
+Bindings for CPU nodes follow the ePAPR standard, available from:
+
+http://devicetree.org
+
+For the ARM architecture every CPU node must contain the following properties:
+
+- device_type:	must be "cpu"
+- reg:		property matching the CPU MPIDR[23:0] register bits
+		reg[31:24] bits must be set to 0
+- compatible:	should be one of:
+		"arm,arm1020"
+		"arm,arm1020e"
+		"arm,arm1022"
+		"arm,arm1026"
+		"arm,arm720"
+		"arm,arm740"
+		"arm,arm7tdmi"
+		"arm,arm920"
+		"arm,arm922"
+		"arm,arm925"
+		"arm,arm926"
+		"arm,arm940"
+		"arm,arm946"
+		"arm,arm9tdmi"
+		"arm,cortex-a5"
+		"arm,cortex-a7"
+		"arm,cortex-a8"
+		"arm,cortex-a9"
+		"arm,cortex-a15"
+		"arm,arm1136"
+		"arm,arm1156"
+		"arm,arm1176"
+		"arm,arm11mpcore"
+		"faraday,fa526"
+		"intel,sa110"
+		"intel,sa1100"
+		"marvell,feroceon"
+		"marvell,mohawk"
+		"marvell,xsc3"
+		"marvell,xscale"
+
+Example:
+
+	cpus {
+		#size-cells = <0>;
+		#address-cells = <1>;
+
+		CPU0: cpu@0 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a15";
+			reg = <0x0>;
+		};
+
+		CPU1: cpu@1 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a15";
+			reg = <0x1>;
+		};
+
+		CPU2: cpu@100 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a7";
+			reg = <0x100>;
+		};
+
+		CPU3: cpu@101 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a7";
+			reg = <0x101>;
+		};
+	};
