      Pull HID updates from Jiri Kosina:
       - Integrated Sensor Hub support (Cherrytrail+) from Srinivas Pandruvada
       - Big cleanup of Wacom driver; namely it's now using devres, and the

         access any more, with substantial amount of other cleanups
         piggy-backing on top. All this from Benjamin Tissoires
       - Report descriptor parsing would now ignore and out-of-range System
         controls in case of the application actually being System Control.
         This fixes quite some issues with several devices, and allows us to
         remove a few ->report_fixup callbacks. From Benjamin Tissoires

       "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.
         - set inline_dentry by default
         - improve discard issue flow
         - add more fault injection cases in f2fs
         - allow block preallocation for encrypted files

         - missing error handling cases detected by fault injection

      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
        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"

       "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....

      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])

      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.

      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
      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.
