       "Another mixture of changes this time around:
      
         - Split XIP linker file from main linker file to make it more
           maintainable, and various XIP fixes, and clean up a resulting
           macro.
      
         - Decompressor cleanups from Masahiro Yamada
      
         - Avoid printing an error for a missing L2 cache
      
         - Remove some duplicated symbols in System.map, and move
           vectors/stubs back into kernel VMA
      
         - Various low priority fixes from Arnd
      
         - Updates to allow bus match functions to return negative errno
           values, touching some drivers and the driver core.  Greg has acked
           these changes.
      
         - Virtualisation platform udpates form Jean-Philippe Brucker.
      
         - Security enhancements from Kees Cook
      
         - Rework some Kconfig dependencies and move PSCI idle management code
           out of arch/arm into drivers/firmware/psci.c
      
         - ARM DMA mapping updates, touching media, acked by Mauro.
      
         - Fix places in ARM code which should be using virt_to_idmap() so
           that Keystone2 can work.
      
         - Fix Marvell Tauros2 to work again with non-DT boots.
      
         - Provide a delay timer for ARM Orion platforms"

       "Highlights:
      
         1) Support more Realtek wireless chips, from Jes Sorenson.
      
         2) New BPF types for per-cpu hash and arrap maps, from Alexei
            Starovoitov.
      
         3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
      
         4) Allow the use of SO_REUSEPORT in order to do per-thread processing
         of incoming TCP/UDP connections.  The muxing can be done using a
         BPF program which hashes the incoming packet.  From Craig Gallek.
      
         5) Add a multiplexer for TCP streams, to provide a messaged based
            interface.  BPF programs can be used to determine the message
            boundaries.  From Tom Herbert.
      
         6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
      
         7) Avoid factorial complexity when taking down an inetdev interface
            with lots of configured addresses.  We were doing things like
            traversing the entire address less for each address removed, and
            flushing the entire netfilter conntrack table for every address as
            well.
      
         8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
      
         9) Allow offloading u32 classifiers to hardware, and implement for
            ixgbe, from John Fastabend.
      
        10) Allow configuring IRQ coalescing parameters on a per-queue basis,
            from Kan Liang.
      
        11) Extend ethtool so that larger link mode masks can be supported.
            From David Decotigny.
      
        12) Introduce devlink, which can be used to configure port link types
            (ethernet vs Infiniband, etc.), port splitting, and switch device
            level attributes as a whole.  From Jiri Pirko.
      
        13) Hardware offload support for flower classifiers, from Amir Vadai.
      
        14) Add "Local Checksum Offload".  Basically, for a tunneled packet
            the checksum of the outer header is 'constant' (because with the
            checksum field filled into the inner protocol header, the payload
            of the outer frame checksums to 'zero'), and we can take advantage
            of that in various ways.  From Edward Cree"

      Pull cgroup updates from Tejun Heo:
       "cgroup changes for v4.6-rc1.  No userland visible behavior changes in
        this pull request.  I'll send out a separate pull request for the
        addition of cgroup namespace support.
      
         - The biggest change is the revamping of cgroup core task migration
           and controller handling logic.  There are quite a few places where
           controllers and tasks are manipulated.  Previously, many of those
           places implemented custom operations for each specific use case
           assuming specific starting conditions.  While this worked, it makes
           the code fragile and difficult to follow.
      
           The bulk of this pull request restructures these operations so that
           most related operations are performed through common helpers which
           implement recursive (subtrees are always processed consistently)
           and idempotent (they make cgroup hierarchy converge to the target
           state rather than performing operations assuming specific starting
           conditions).  This makes the code a lot easier to understand,
           verify and extend.
      
         - Implicit controller support is added.  This is primarily for using
           perf_event on the v2 hierarchy so that perf can match cgroup v2
           path without requiring the user to do anything special.  The kernel
           portion of perf_event changes is acked but userland changes are
           still pending review.
      
         - cgroup_no_v1= boot parameter added to ease testing cgroup v2 in
           certain environments.
      
         - There is a regression introduced during v4.4 devel cycle where
           attempts to migrate zombie tasks can mess up internal object
           management.  This was fixed earlier this week and included in this
           pull request w/ stable cc'd.
      
         - Misc non-critical fixes and improvements"

      bonding: fix bond_get_stats() · fe30937b
      Eric Dumazet authored
      bond_get_stats() can be called from rtnetlink (with RTNL held)
      or from /proc/net/dev seq handler (with RCU held)
      
      The logic added in commit 5f0c5f73 ("bonding: make global bonding
      stats more reliable") kind of assumed only one cpu could run there.
      
      If multiple threads are reading /proc/net/dev, stats can be really
      messed up after a while.
      
      A second problem is that some fields are 32bit, so we need to properly
      handle the wrap around problem.
      
      Given that RTNL is not always held, we need to use
      bond_for_each_slave_rcu().

      net/mlx4_core: Fix backward compatibility on VFs · 76e39ccf
      Eli Cohen authored
      Commit 85743f1e ("net/mlx4_core: Set UAR page size to 4KB regardless
      of system page size") introduced dependency where old VF drivers without
      this fix fail to load if the PF driver runs with this commit.
      
      To resolve this add a module parameter which disables that functionality
      by default.  If both the PF and VFs are running with a driver with that
      commit the administrator may set the module param to true.
      
      The module parameter is called enable_4k_uar.

      RDS: TCP: Add sysctl tunables for sndbuf/rcvbuf on rds-tcp socket · c6a58ffe
      Sowmini Varadhan authored
      Add per-net sysctl tunables to set the size of sndbuf and
      rcvbuf on the kernel tcp socket.
      
      The tunables are added at /proc/sys/net/rds/tcp/rds_tcp_sndbuf
      and /proc/sys/net/rds/tcp/rds_tcp_rcvbuf.
      
      These values must be set before accept() or connect(),
      and there may be an arbitrary number of existing rds-tcp
      sockets when the tunable is modified. To make sure that all
      connections in the netns pick up the same value for the tunable,
      we reset existing rds-tcp connections in the netns, so that
      they can reconnect with the new parameters.

      net: smc911x: convert pxa dma to dmaengine · 79d3b59a
      Robert Jarzmik authored
      Convert the dma transfers to be dmaengine based, now pxa has a dmaengine
      slave driver. This makes this driver a bit more PXA agnostic.
      
      The driver was only compile tested. The risk is quite small as no
      current PXA platform I'm aware of is using smc911x driver.

      Pull block driver updates from Jens Axboe:
       "This is the block driver pull request for this merge window.  It sits
        on top of for-4.6/core, that was just sent out.
      
        This contains:
      
         - A set of fixes for lightnvm.  One from Alan, fixing an overflow,
           and the rest from the usual suspects, Javier and Matias.
      
         - A set of fixes for nbd from Markus and Dan, and a fixup from Arnd
           for correct usage of the signed 64-bit divider.
      
         - A set of bug fixes for the Micron mtip32xx, from Asai.
      
         - A fix for the brd discard handling from Bart.
      
         - Update the maintainers entry for cciss, since that hardware has
           transferred ownership.
      
         - Three bug fixes for bcache from Eric Wheeler.
      
         - Set of fixes for xen-blk{back,front} from Jan and Konrad.
      
         - Removal of the cpqarray driver.  It has been disabled in Kconfig
           since 2013, and we were initially scheduled to remove it in 3.15.
      
         - Various updates and fixes for NVMe, with the most important being:
      
              - Removal of the per-device NVMe thread, replacing that with a
                watchdog timer instead. From Christoph.
      
              - Exposing the namespace WWID through sysfs, from Keith.
      
              - Set of cleanups from Ming Lin.
      
              - Logging the controller device name instead of the underlying
                PCI device name, from Sagi.
      
              - And a bunch of fixes and optimizations from the usual suspects
