    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 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"

  • 832f5dacf   MIPS: Remove all the uses of custom gpio.h ... Browse Code »

    Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS
    machines, and each machine type provides its own gpio.h. However
    only a handful really implement the GPIO API, most just forward
    everythings to gpiolib.

    The Alchemy machine is notable as it provides a system to allow
    implementing the GPIO API at the board level. But it is not used by
    any board currently supported, so it can also be removed.

    For most machine types we can just remove the custom gpio.h, as well
    as the custom wrappers if some exists. Some of the code found in
    the wrappers must be moved to the respective GPIO driver.

    A few more fixes are need in some drivers as they rely on linux/gpio.h
    to provides some machine specific definitions, or used asm/gpio.h
    instead of linux/gpio.h for the gpio API.

    Commit 0046be10e0c502705fc74d91408eba13a73bc201 ("mips: delete
    non-required instances of include ") inadvertently
    removed an include that was actually correct. Restore it.

    Note that it gets init.h implicitly anyway, so this is largely a
    cosmetic fixup; no build regressions were caused by this.

    Pull MIPS updates from Ralf Baechle:
    "The most notable new addition inside this pull request is the support
    for MIPS's latest and greatest core called "inter/proAptiv". The
    patch series describes this core as follows.

    "The interAptiv is a power-efficient multi-core microprocessor
    for use in system-on-chip (SoC) applications. The interAptiv combines
    a multi-threading pipeline with a coherence manager to deliver improved
    computational throughput and power efficiency. The interAptiv can
    contain one to four MIPS32R3 interAptiv cores, system level
    coherence manager with L2 cache, optional coherent I/O port,
    and optional floating point unit."

    The platform specific patches touch all 3 Broadcom families. It adds
    support for the new Broadcom/Netlogix XLP9xx Soc, building a common
    BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count
    and full gpio button/led descriptions for BCM47xx.

    The rest of the series are cleanups and bug fixes that are MIPS
    generic and consist largely of changes that Imgtec/MIPS had published
    in their linux-mti-3.10.git stable tree. Random other cleanups and
    patches preparing code to be merged in 3.15"

    Shamelessly stealing wisdom from pasemi_mac.c, I found char2hex() could

    least. The result is 100 bytes trimmed off the size of a compiled
    cpmac_get_mac() and as an extra bonus it grumbles and gracefully fails
    over to using random_ether_addr() when an attempt to parse an invalid
    MAC address is made.
