Pull MIPS updates from Ralf Baechle:
 "This is an unusually large pull request for MIPS - in parts because
  lots of patches missed the 3.18 deadline but primarily because some
  folks opened the flood gates.

   - Improvments for the backtrace code used by oprofile.
   - Better backtraces on SMP systems.
   - Cleanups for the Octeon platform code.
   - Cleanups and fixes for the Loongson platform code.

   - Support for new style FPU register model in O32
   - VDSO randomization.
   - BCM47xx cleanups
   - BCM47xx reimplement the way the kernel accesses NVRAM information.

MIPS Global Interrupt Controller (GIC)
The MIPS GIC routes external interrupts to individual VPEs and IRQ pins.
It also supports local (per-processor) interrupts and software-generated
interrupts which can be used as IPIs. The GIC also includes a free-running
global timer, per-CPU count/compare timers, and a watchdog.
Required properties:
- compatible : Should be "mti,gic".
- interrupt-controller : Identifies the node as an interrupt controller
- #interrupt-cells : Specifies the number of cells needed to encode an
interrupt specifier. Should be 3.
- The first cell is the type of interrupt, local or shared.
See <include/dt-bindings/interrupt-controller/mips-gic.h>.
- The second cell is the GIC interrupt number.
- The third cell encodes the interrupt flags.
See <include/dt-bindings/interrupt-controller/irq.h> for a list of valid
flags.
Optional properties:
- reg : Base address and length of the GIC registers. If not present,
the base address reported by the hardware GCR_GIC_BASE will be used.
- mti,reserved-cpu-vectors : Specifies the list of CPU interrupt vectors
to which the GIC may not route interrupts. Valid values are 2 - 7.
This property is ignored if the CPU is started in EIC mode.
Required properties for timer sub-node:
- compatible : Should be "mti,gic-timer".
- interrupts : Interrupt for the GIC local timer.
- clock-frequency : Clock frequency at which the GIC timers operate.
Example:
gic: interrupt-controller@1bdc0000 {
compatible = "mti,gic";
reg = <0x1bdc0000 0x20000>;
interrupt-controller;
#interrupt-cells = <3>;
mti,reserved-cpu-vectors = <7>;
timer {
compatible = "mti,gic-timer";
interrupts = <GIC_LOCAL 1 IRQ_TYPE_NONE>;
clock-frequency = <50000000>;
};
};
uart@18101400 {
...
interrupt-parent = <&gic>;
interrupts = <GIC_SHARED 24 IRQ_TYPE_LEVEL_HIGH>;
...
};

* Interrupt Controller
Properties:
- compatible: "brcm,bcm3384-intc"
Compatibility with BCM3384 and possibly other BCM33xx/BCM63xx SoCs.
- reg: Address/length pairs for each mask/status register set. Length must
be 8. If multiple register sets are specified, the first set will
handle IRQ offsets 0..31, the second set 32..63, and so on.
- interrupt-controller: This is an interrupt controller.
- #interrupt-cells: Must be <1>. Just a simple IRQ offset; no level/edge
or polarity configuration is possible with this controller.
- interrupt-parent: This controller is cascaded from a MIPS CPU HW IRQ, or
from another INTC.
- interrupts: The IRQ on the parent controller.
Example:
periph_intc: periph_intc@14e00038 {
compatible = "brcm,bcm3384-intc";
/*
* IRQs 0..31: mask reg 0x14e00038, status reg 0x14e0003c
* IRQs 32..63: mask reg 0x14e00340, status reg 0x14e00344

* Broadcom USB controllers
Required properties:
- compatible: "brcm,bcm3384-ohci", "brcm,bcm3384-ehci"
These currently use the generic-ohci and generic-ehci drivers. On some

- Restoring state after systemwide power save modes
- Sharing PHYs with the USBD (UDC) hardware
- Figuring out which controllers are disabled on ASIC bondout variants
