Pull new ARC architecture from Vineet Gupta:
 "Initial ARC Linux port with some fixes on top for 3.9-rc1:

  I would like to introduce the Linux port to ARC Processors (from
  Synopsys) for 3.9-rc1.  The patch-set has been discussed on the public
  lists since Nov and has received a fair bit of review, specially from
  Arnd, tglx, Al and other subsystem maintainers for DeviceTree, kgdb...

  The arch bits are in arch/arc, some asm-generic changes (acked by
  Arnd), a minor change to PARISC (acked by Helge).

  The series is a touch bigger for a new port for 2 main reasons:

   1. It enables a basic kernel in first sub-series and adds
      ptrace/kgdb/.. later

   2. Some of the fallout of review (DeviceTree support, multi-platform-
      image support) were added on top of orig series, primarily to
      record the revision history.

  This updated pull request additionally contains

   - fixes due to our GNU tools catching up with the new syscall/ptrace
     ABI

   - some (minor) cross-arch Kconfig updates."

* ARC700 incore Interrupt Controller

The core interrupt controller provides 32 prioritised interrupts (2 levels)
to ARC700 core.

Properties:

- compatible: "snps,arc700-intc"
- interrupt-controller: This is an interrupt controller.
- #interrupt-cells: Must be <1>.

Single Cell "interrupts" property of a device specifies the IRQ number
between 0 to 31

intc accessed via the special ARC AUX register interface, hence "reg" property
is not specified.

Example:

intc: interrupt-controller {
compatible = "snps,arc700-intc";
interrupt-controller;
#interrupt-cells = <1>;
};
