      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've investigated how f2fs deals with errors given by
        our fault injection facility. With this, we could fix several corner
        cases. And, in order to improve the performance, we set inline_dentry
        by default and enhance the exisiting discard issue flow. In addition,
        we added f2fs_migrate_page for better memory management.
      
        Enhancements:
         - set inline_dentry by default
         - improve discard issue flow
         - add more fault injection cases in f2fs
         - allow block preallocation for encrypted files
         - introduce migrate_page callback function
         - avoid truncating the next direct node block at every checkpoint
      
        Bug fixes:
         - set page flag correctly between write_begin and write_end
         - missing error handling cases detected by fault injection
         - preallocate blocks regarding to 4KB alignement correctly
         - dentry and filename handling of encryption
         - lost xattrs of directories"

      Pull namespace updates from Eric Biederman:
       "This set of changes is a number of smaller things that have been
        overlooked in other development cycles focused on more fundamental
        change. The devpts changes are small things that were a distraction
        until we managed to kill off DEVPTS_MULTPLE_INSTANCES. There is an
        trivial regression fix to autofs for the unprivileged mount changes
        that went in last cycle. A pair of ioctls has been added by Andrey
        Vagin making it is possible to discover the relationships between
        namespaces when referring to them through file descriptors.
      
        The big user visible change is starting to add simple resource limits
        to catch programs that misbehave. With namespaces in general and user
        namespaces in particular allowing users to use more kinds of
        resources, it has become important to have something to limit errant
        programs. Because the purpose of these limits is to catch errant
        programs the code needs to be inexpensive to use as it always on, and
        the default limits need to be high enough that well behaved programs
        on well behaved systems don't encounter them.
      
        To this end, after some review I have implemented per user per user
        namespace limits, and use them to limit the number of namespaces. The
        limits being per user mean that one user can not exhause the limits of
        another user. The limits being per user namespace allow contexts where
        the limit is 0 and security conscious folks can remove from their
        threat anlysis the code used to manage namespaces (as they have
        historically done as it root only). At the same time the limits being
        per user namespace allow other parts of the system to use namespaces.
      
        Namespaces are increasingly being used in application sand boxing
        scenarios so an all or nothing disable for the entire system for the
        security conscious folks makes increasing use of these sandboxes
        impossible.
      
        There is also added a limit on the maximum number of mounts present in
        a single mount namespace. It is nontrivial to guess what a reasonable
        system wide limit on the number of mount structure in the kernel would
        be, especially as it various based on how a system is using
        containers. A limit on the number of mounts in a mount namespace
        however is much easier to understand and set. In most cases in
        practice only about 1000 mounts are used. Given that some autofs
        scenarious have the potential to be 30,000 to 50,000 mounts I have set
        the default limit for the number of mounts at 100,000 which is well
        above every known set of users but low enough that the mount hash
        tables don't degrade unreaonsably.
      
        These limits are a start. I expect this estabilishes a pattern that
        other limits for resources that namespaces use will follow. There has
        been interest in making inotify event limits per user per user
        namespace as well as interest expressed in making details about what
        is going on in the kernel more visible"

      Pull xfs and iomap updates from Dave Chinner:
       "The main things in this update are the iomap-based DAX infrastructure,
        an XFS delalloc rework, and a chunk of fixes to how log recovery
        schedules writeback to prevent spurious corruption detections when
        recovery of certain items was not required.
      
        The other main chunk of code is some preparation for the upcoming
        reflink functionality. Most of it is generic and cleanups that stand
        alone, but they were ready and reviewed so are in this pull request.
      
        Speaking of reflink, I'm currently planning to send you another pull
        request next week containing all the new reflink functionality. I'm
        working through a similar process to the last cycle, where I sent the
        reverse mapping code in a separate request because of how large it
        was. The reflink code merge is even bigger than reverse mapping, so
        I'll be doing the same thing again....
      
        Summary for this update:
      
         - change of XFS mailing list to linux-xfs@vger.kernel.org
      
         - iomap-based DAX infrastructure w/ XFS and ext2 support
      
         - small iomap fixes and additions
      
         - more efficient XFS delayed allocation infrastructure based on iomap
      
         - a rework of log recovery writeback scheduling to ensure we don't
           fail recovery when trying to replay items that are already on disk
      
         - some preparation patches for upcoming reflink support
      
         - configurable error handling fixes and documentation

         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

      xen/x86: Update topology map for PV VCPUs · a6a198bc
      Boris Ostrovsky authored
      Early during boot topology_update_package_map() computes
      logical_pkg_ids for all present processors.
      
      Later, when processors are brought up, identify_cpu() updates
      these values based on phys_pkg_id which is a function of
      initial_apicid. On PV guests the latter may point to a
      non-existing node, causing logical_pkg_ids to be set to -1.
      
      Intel's RAPL uses logical_pkg_id (as topology_logical_package_id())
      to index its arrays and therefore in this case will point to index
      65535 (since logical_pkg_id is a u16). This could lead to either a
      crash or may actually access random memory location.
      
      As a workaround, we recompute topology during CPU bringup to reset
      logical_pkg_id to a valid value.
      
      (The reason for initial_apicid being bogus is because it is
      initial_apicid of the processor from which the guest is launched.
      This value is CPUID(1).EBX[31:24])

      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.

      sparc64: PCIe performance enhancements
      
      Ver 2 is redone for 4.8 where commit 00085f1e
      changed DMA attributes from struct pointer to unsigned long.
      
      This set of patches initiates a series of PCIe performance enhancement patch
      submittals.
      
      Patch 1/2 enables version 2 of the SPARC sun4v IOMMU I/O address translation
      services need for subsequent enhancements.
      
      Patch 2/2 allows drivers to specify DMA_ATTR_WEAK_ORDERING via DMA attributes
      to the SPARC DMA mapping routines enabling "relaxed ordering" for the buffer
      being mapped.

      sparc64: Enable setting "relaxed ordering" in IOMMU mappings · aa7bde1a
      chris hyser authored
      Enable relaxed ordering for memory writes in IOMMU TSB entry from
      dma_4v_alloc_coherent(), dma_4v_map_page() and dma_4v_map_sg() when
      dma_attrs DMA_ATTR_WEAK_ORDERING is set. This requires PCI IOMMU I/O
      Translation Services version 2.0 API.
      
      Many PCIe devices allow enabling relaxed-ordering (memory writes bypassing
      other memory writes) for various DMA buffers. A notable exception is the
      Mellanox mlx4 IB adapter. Due to the nature of x86 HW this appears to have
      little performance impact there. On SPARC HW however, this results in major
      performance degradation getting only about 3Gbps. Enabling RO in the IOMMU
      entries corresponding to mlx4 data buffers increases the throughput to
      about 13 Gbps.

      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"

       "Again the diffstat shows a widely distributed pattern at this cycle,
        as there've been many code cleanups and refactoring allover the
        places. Other than that, the development was relatively calm, and no
        big surprise shouldn't be expected. Here are some highlights:
      
        Core:
         - Sequencer code refactoring / documentation updates
         - TLV code moved to uapi, following some relevant cleanups
      
        USB-Audio:
         - Lots of LINE6 driver fixes / updates
         - DragonFly and TEAC device quirk updates
      
        HD-audio:
         - Usual fixupes for Dell, Lenovo and HP machines

      Linus Torvalds authored
      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"

       "This is the bulk of pin control changes for the v4.9 cycle.

        Driver improvements:
      
         - drop default IRQ trigger types assigned during IRQ mapping on AT91
