       - Correct ARMs dma-mapping to use the correct printk format strings.
      
       - Avoid defining OBJCOPYFLAGS globally which upsets lkdtm rodata
         testing.
      
       - Cleanups to ARMs asm/memory.h include.
      
       - L2 cache cleanups.
      
       - Allow flat nommu binaries to be executed on ARM MMU systems.
      
       - Kernel hardening - add more read-only after init annotations,
         including making some kernel vdso variables const.
      
       - Ensure AMBA primecell clocks are appropriately defaulted.
      
       - ARM breakpoint cleanup.
      
       - Various StrongARM 11x0 and companion chip (SA1111) updates to bring
         this legacy platform to use more modern APIs for (eg) GPIOs and
         interrupts, which will allow us in the future to reduce some of the
         board-level driver clutter and elimate function callbacks into board
         code via platform data. There still appears to be interest in these
         platforms!
      
       - Remove the now redundant secure_flush_area() API.
      
       - Module PLT relocation optimisations. Ard says: This series of 4
         patches optimizes the ARM PLT generation code that is invoked at
         module load time, to get rid of the O(n^2) algorithm that results in
         pathological load times of 10 seconds or more for large modules on
         certain STB platforms.
      
       - ARMv7M cache maintanence support.
      
       - L2 cache PMU support

      ARM: fix delays · fb833b1f
      Russell King authored
      Commit 215e362d ("ARM: 8306/1: loop_udelay: remove bogomips value
      limitation") tried to increase the bogomips limitation, but in doing
      so messed up udelay such that it always gives about a 5% error in the
      delay, even if we use a timer.
      
      The calculation is:
      
      	loops = UDELAY_MULT * us_delay * ticks_per_jiffy >> UDELAY_SHIFT
      
      Originally, UDELAY_MULT was ((UL(2199023) * HZ) >> 11) and UDELAY_SHIFT
      30.  Assuming HZ=100, us_delay of 1000 and ticks_per_jiffy of 1660000
      (eg, 166MHz timer, 1ms delay) this would calculate:
      
      	((UL(2199023) * HZ) >> 11) * 1000 * 1660000 >> 30
      		=> 165999
      
      With the new values of 2047 * HZ + 483648 * HZ / 1000000 and 31, we get:
      
      	(2047 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31
      		=> 158269
      
      which is incorrect.  This is due to a typo - correcting it gives:
      
      	(2147 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31
      		=> 165999
      
      i.o.w, the original value.

      Linus Torvalds authored
      Pull staging and IIO updates from Greg KH:
       "Here is the big staging and IIO driver pull request for 4.9-rc1.
      
        There are a lot of patches in here, the majority due to the
        drivers/staging/greybus/ subsystem being merged in with full
        development history that went back a few years, in order to preserve
        the work that those developers did over time.
      
        Lots and lots of tiny cleanups happened in the tree as well, due to
        the Outreachy application process and lots of other developers showing
        up for the first time to clean code up.  Along with those changes, we
        deleted a wireless driver, and added a raspberrypi driver (currently
        marked broken), and lots of new iio drivers.
      
        Overall the tree still shrunk with more lines removed than added,
        about 10 thousand lines removed in total. Full details are in the very
        long shortlog below.
      
        All of this has been in the linux-next tree with no issues. There will
        be some merge problems with other subsystem trees, but those are all
        minor problems and shouldn't be hard to work out when they happen
        (MAINTAINERS and some lustre build problems with the IB tree)"
      
      And furter from me asking for clarification about greybus:
       "Right now there is a phone from Motorola shipping with this code (a
        slightly older version, but the same tree), so even though Ara is not
        alive in the same form, the functionality is happening. We are working
        with the developers of that phone to merge the newer stuff in with
        their fork so they can use the upstream version in future versions of
        their phone product line.
      
        Toshiba has at least one chip shipping in their catalog that
        needs/uses this protocol over a Unipro link, and rumor has it that
        there might be more in the future.
      
        There are also other users of the greybus protocols, there is a talk
        next week at ELC that shows how it is being used across a network
        connection to control a device, and previous ELC talks have showed the
        protocol stack being used over USB to drive embedded Linux boards.
        I've also talked to some people who are starting to work to add a host
        controller driver to control arduinos as the greybus PHY protocols are
        very useful to control a serial/i2c/spio/whatever device across a
        random physical link, as it is a way to have a self-describing device
        be attached to a host without needing manual configuration.
      
        So yes, people are using it, and there is still the chance that it
        will show up in a phone/laptop/tablet/whatever from Google in the
        future as well, the tech isn't dead, even if the original large phone
        project happens to be"

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.9 series:
      
        Subsystem improvements:
      
         - do away with the last users of the obsolete Kconfig options
           ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
           always sounded like an item on a wishlist to Santa Claus to me). We
           can now select GPIOLIB and be done with it, for all archs. After
           some struggle it even work on UM. Not that it has GPIO, but if it
           wants to, it can select the library.
      
         - continued efforts to make drivers properly either tristate or bool.
      
         - introduce a warning for drivers assigning default triggers to their
           irqchip lines when probed from device tree, so we find and fix
           these ambigous drivers. It is agreed that in the OF config path,
           the device tree defines trigger characteristics.
      
         - the same warning, mutatis mutandis, for ACPI-probed GPIO irqchips.
      
         - we introduce the ability to mark certain IRQ lines as "unusable" as
           they can be taken by BIOS/firmware, unrouted in silicon and
           generally nasty if you use them, and such things. This is put to
           good use in the STMPE driver and also in the Cherryview pin control
           driver.
      
         - a new "mockup" virtual GPIO device that can be used for testing.
           The plan is to add unit tests under tools/* for exercising this
           device and verify that the kernel code paths are working as they
           should.
      
         - make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
           implicit all the time, but when people started building UM with
           allyesconfig or allmodconfig it exploded in their face.
      
         - move some stray bits of device tree and ACPI HW description
           callbacks down into their respective implementation silo. These
           were causing issues when compiling on !HAS_IOMEM as well, so now
           eventually UM compiles the GPIOLIB library if it wants to.
      
        New drivers:
      
         - new driver for the Aspeed GPIO front-end companion to the pin
           controller merged through the pin control tree.
      
         - new driver for the LP873x PMIC GPIO portions.
      
         - new driver for Technologic Systems' I2C FPGA GPIO such as TS4900,
           TS-7970, TS-7990 and TS-4100.
      
         - new driver for the Broadcom BCM63xx series including BCM6338 and
           BCM6345.
      
         - new driver for the Intel WhiskeyCove PMIC GPIO.
      
         - new driver for the Allwinner AXP209 PMIC GPIO portions.
      
         - new driver for Diamond Systems 48 line GPIO-MM, another of these
           port-mapped I/O expansion cards.
      
         - support the STMicroelectronics STMPE1600 variant in the STMPE
           driver.
      
        Driver improvements:
      
         - the STMPE driver now supports rising/falling edge detection
           properly for IRQs.
      
         - the PCA954x will now fetch and enable its VCC regulator properly.
      
         - major rework of the PCA953x driver with the goal of eventually
           switching it over to use regmap and thus modernize it even more.
      
         - switch the IOP driver to use the generic MMIO GPIO library.
      
         - move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
           over to this subsystem from MFD, achieveing some separation of
           concerns"

      mm: filemap: fix mapping->nrpages double accounting in fuse · 3ddf40e8
      Johannes Weiner authored
      Commit 22f2ac51 ("mm: workingset: fix crash in shadow node shrinker
      caused by replace_page_cache_page()") switched replace_page_cache() from
      raw radix tree operations to page_cache_tree_insert() but didn't take
      into account that the latter function, unlike the raw radix tree op,
      handles mapping->nrpages.  As a result, that counter is bumped for each
      page replacement rather than balanced out even.
      
      The mapping->nrpages counter is used to skip needless radix tree walks
      when invalidating, truncating, syncing inodes without pages, as well as
      statistics for userspace.  Since the error is positive, we'll do more
      page cache tree walks than necessary; we won't miss a necessary one.
      And we'll report more buffer pages to userspace than there are.  The
      error is limited to fuse inodes.

      This is a long-standing bug in the way shadow entries are accounted in
      the radix tree nodes. The shrinker needs to know when radix tree nodes
      contain only shadow entries, no pages, so node->count is split in half
      to count shadows in the upper bits and pages in the lower bits.
      
      Unfortunately, the radix tree implementation doesn't know of this and
      assumes all entries are in node->count. When there is a shadow entry
      directly in root->rnode and the tree is later extended, the radix tree
      implementation will copy that entry into the new node and and bump its
      node->count, i.e. increases the page count bits. Once the shadow gets
      removed and we subtract from the upper counter, node->count underflows
      and triggers the warning. Afterwards, without node->count reaching 0
      again, the radix tree node is leaked.
      
      Limit shadow entries to when we have actual radix tree nodes and can
      count them properly. That means we lose the ability to detect refaults
      from files that had only the first page faulted in at eviction time.

        The Sphinx transition is still creating a fair amount of work. Here we

        thanks to Jani Nikula, Mauro Carvalho Chehab and Markus Heiser.
      
        I've started a couple of new books: a driver API book (based on the
        old device-drivers.tmpl) and a development tools book. Both are meant
        to show how we can integrate together our existing documentation into
        a more coherent and accessible whole. It involves moving some stuff
        around and formatting changes, but, I think, the results are worth it.
        The good news is that most of our existing Documentation/*.txt files
        are *almost* in RST format already; the amount of messing around
        required is minimal.

      Pull clk framework updates from Stephen Boyd:
       "The core clk framework changes are small again. They're mostly minor
        fixes that weren't causing enough problems (or any problems when we're
        just clarifying things) to warrant sending outside the merge window.
        The majority of changes are in drivers for various SoCs. Full details
        are in the logs, but here's the summary.
      
        Core:
      
         - Better support for DeviceTree overlays with the addition of the
           CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver for a
           device node that matched during of_clk_init(), unless the driver
           uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE. This allows
           overlays to work cleanly for drivers that must probe before the
           device model is ready, and also after it's ready when an overlay is
           loaded.
      
         - Clarification in the code around how clk_hw pointers are returned
           from of clk providers
      
         - Proper migration of prepare/enable counts to parents when the clk
           tree is constructed
      
        New Drivers:
      
         - Socionext's UniPhier SoCs
         - Loongson1C
         - ZTE ZX296718
         - Qualcomm MDM9615
         - Amlogic GXBB AO clocks and resets
         - Broadcom BCM53573 ILP
         - Maxim MAX77620
      
       Updates:
      
         - Four Allwinner SoCs are migrated to the new style clk driver (A31,
           A31s, A23 and A33)
         - Exynos 5xxx audio and DRAM clks
         - Loongson1B AC97, DMA and NAND clks
         - Rockchip DDR clks and rk3399 driver tweaks
         - Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer
           clks
         - Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W
         - Amlogic GXBB MMC gate clks
         - at91 sama5d4 sckc
         - Removal of STiH415 and STiH416 clk support as the SoC is being
           removed
         - Rework of STiH4xx clk support for new style bindings
         - Continuation of driver migration to clk_hw based registration APIs
         - xgene PMD support
         - bcm2835 critical clk markings
         - ARM versatile ICST"
