Pull powerpc updates from Ben Herrenschmidt:
 "Here is the bulk of the powerpc changes for this merge window.  It got
  a bit delayed in part because I wasn't paying attention, and in part
  because I discovered I had a core PCI change without a PCI maintainer
  ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
  probably improve it later and I didn't want to rebase to add his ack.

  There is going to be a bit more next week, essentially fixes that I
  still want to sort through and test.

  The biggest item this time is the support to build the ppc64 LE kernel
  with our new v2 ABI.  We previously supported v2 userspace but the
  kernel itself was a tougher nut to crack.  This is now sorted mostly
  thanks to Anton and Rusty.

  We also have a fairly big series from Cedric that add support for
  64-bit LE zImage boot wrapper.  This was made harder by the fact that
  traditionally our zImage wrapper was always 32-bit, but our new LE
  toolchains don't really support 32-bit anymore (it's somewhat there
  but not really "supported") so we didn't want to rely on it.  This
  meant more churn that just endian fixes.

  This brings some more LE bits as well, such as the ability to run in
  LE mode without a hypervisor (ie. under OPAL firmware) by doing the
  right OPAL call to reinitialize the CPU to take HV interrupts in the
  right mode and the usual pile of endian fixes.

  There's another series from Gavin adding EEH improvements (one day we
  *will* have a release with less than 20 EEH patches, I promise!).

  Another highlight is the support for the "Split core" functionality on
  P8 by Michael.  This allows a P8 core to be split into "sub cores" of
  4 threads which allows the subcores to run different guests under KVM
  (the HW still doesn't support a partition per thread).

  And then the usual misc bits and fixes ..."

[ Further delayed by gmail deciding that BenH is a dirty spammer.
  Google knows.  ]

+Description:	Default value for the Data Stream Control Register (DSCR) on
+		a CPU.
+		This default value is used when the kernel is executing and
+		for any process that has not set the DSCR itself.
+		If a process ever sets the DSCR (via direct access to the
+		SPR) that value will be persisted for that process and used
+		on any CPU where it executes (overriding the value described
+		here).
+		If set by a process it will be inherited by child processes.
+Values:		64 bit unsigned integer (bit field)

+them to a single controller.
+
+Required properties:
+- compatible: "keymile,bfticu"
+- interrupt-controller: the bfticu FPGA is an interrupt controller
+- interrupts: the main IRQ line to signal the collected IRQs
+- #interrupt-cells : is 2 and their usage is compliant to the 2 cells variant
+  of Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+- interrupt-parent: the parent IRQ ctrl the main IRQ is connected to
+- reg: access on the parent local bus (chip select, offset in chip select, size)
+
+Example:
+
+	chassis-mgmt@3,0 {
+		compatible = "keymile,bfticu";
+		interrupt-controller;
+		#interrupt-cells = <2>;
+		reg = <3 0 0x100>;
+		interrupt-parent = <&mpic>;
+		interrupts = <6 1 0 0>;

+==============================================
+
+The 476gtr SoC contains a high speed serial assist module attached
+between the plb4 and plb6 system buses to provide high speed data
+transfer between memory and system peripherals as well as support for
+PCI message signalled interrupts.
+
+Currently only the MSI support is used by Linux using the following

+
+Require properties:
+- compatible		: "ibm,476gtr-hsta-msi", "ibm,hsta-msi"
+- reg			: register mapping for the HSTA MSI space
+- interrupt-parent	: parent controller for mapping interrupts
+- interrupts		: ordered interrupt mapping for each MSI in the register
+			  space. The first interrupt should be associated with a
+			  register offset of 0x00, the second to 0x10, etc.

+Freescale CoreNet Coherency Fabric(CCF) Device Tree Binding
+
+DESCRIPTION
+
+The CoreNet coherency fabric is a fabric-oriented, connectivity infrastructure
+that enables the implementation of coherent, multicore systems.
+
+Required properties:
+
+- compatible: <string list>
+		fsl,corenet1-cf - CoreNet coherency fabric version 1.
+		Example chips: T4240, B4860
+
+		fsl,corenet2-cf - CoreNet coherency fabric version 2.
+		Example chips: P5040, P5020, P4080, P3041, P2041
+
+		fsl,corenet-cf - Used to represent the common registers
+		between CCF version 1 and CCF version 2.  This compatible
+		is retained for compatibility reasons, as it was already
+		used for both CCF version 1 chips and CCF version 2
+		chips.  It should be specified after either
+		"fsl,corenet1-cf" or "fsl,corenet2-cf".
+
+- reg: <prop-encoded-array>
+		A standard property. Represents the CCF registers.
+
+- interrupts: <prop-encoded-array>
+		Interrupt mapping for CCF error interrupt.
+
+- fsl,ccf-num-csdids: <u32>
+		Specifies the number of Coherency Subdomain ID Port Mapping
+		Registers that are supported by the CCF.
+
+- fsl,ccf-num-snoopids: <u32>
+		Specifies the number of Snoop ID Port Mapping Registers that
+		are supported by CCF.
+
+Example:
+
+	corenet-cf@18000 {
+		compatible = "fsl,corenet2-cf", "fsl,corenet-cf";
+		reg = <0x18000 0x1000>;
