Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus 

Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for 4.3 for MIPS.  Here's the summary:

  Three fixes that didn't make 4.2-stable:

   - a -Os build might compile the kernel using the MIPS16 instruction
     set but the R2 optimized inline functions in <uapi/asm/swab.h> are
     implemented using 32-bit wide instructions which is invalid.

   - a build error in pgtable-bits.h for a particular kernel
     configuration.

   - accessing registers of the CM GCR might have been compiled to use
     64 bit accesses but these registers are onl 32 bit wide.

  And also a few new bits:

   - move the ATH79 GPIO driver to drivers/gpio

   - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
     change ATH79 accordingly.

   - fix definition of pgprot_writecombine

   - add an implementation of dma_map_ops.mmap

   - fix alignment of quiet build output for vmlinuz link

   - BCM47xx: Use kmemdup rather than duplicating its implementation

   - Netlogic: Fix 0x0x prefixes of constants.

   - merge Bjorn Helgaas' series to remove most of the weak keywords
     from function declarations.

   - CP0 and CP1 registers are best considered treated as unsigned
     values to avoid large values from becoming negative values.

   - improve support for the MIPS GIC timer.

   - enable common clock framework for Malta and SEAD3.

   - a number of improvments and fixes to dump_tlb().

   - document the MIPS TLB dump functionality in Magic SysRq.

   - Cavium Octeon CN68XX improvments.

   - NetLogic improvments.

   - irq: Use access helper irq_data_get_affinity_mask.

   - handle MSA unaligned accesses.

   - a number of R6-related math-emu fixes.

   - support for I6400.

   - improvments to MSA support.

   - add uprobes support.

   - move from deprecated __initcall to arch_initcall.

   - remove finish_arch_switch().

   - IRQ cleanups by Thomas Gleixner.

   - migrate to new 'set-state' interface.

   - random small cleanups"

* Pistachio general-purpose timer based clocksource
Required properties:
- compatible: "img,pistachio-gptimer".
- reg: Address range of the timer registers.
- interrupts: An interrupt for each of the four timers
- clocks: Should contain a clock specifier for each entry in clock-names
- clock-names: Should contain the following entries:
"sys", interface clock
"slow", slow counter clock
"fast", fast counter clock
- img,cr-periph: Must contain a phandle to the peripheral control
syscon node.
Example:
timer: timer@18102000 {
compatible = "img,pistachio-gptimer";
reg = <0x18102000 0x100>;
interrupts = <GIC_SHARED 60 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SHARED 61 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SHARED 62 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SHARED 63 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk_periph PERIPH_CLK_COUNTER_FAST>,
<&clk_periph PERIPH_CLK_COUNTER_SLOW>,
<&cr_periph SYS_CLK_TIMER>;
clock-names = "fast", "slow", "sys";
img,cr-periph = <&cr_periph>;
};

* sigcontext. They are placed sequentially in memory at the end of struct
* ucontext and struct sigframe, with each extended context structure beginning
* with a header defined by this struct. The type of context represented is
* indicated by the magic field. Userland may check each extended context
* structure against magic values that it recognises. The size field allows any
* unrecognised context to be skipped, allowing for future expansion. The end
* of the extended context data is indicated by the magic value
* END_EXTCONTEXT_MAGIC.
