      Pull networking updates from David Miller:
      
       1) New ipset extensions for matching on destination MAC addresses, from
          Stefano Brivio.
      
       2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to
          nfp driver. From Stefano Brivio.
      
       3) Implement GRO for plain UDP sockets, from Paolo Abeni.
      
       4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT
          bit so that we could support the entire vlan_tci value.
      
       5) Rework the IPSEC policy lookups to better optimize more usecases,
          from Florian Westphal.
      
       6) Infrastructure changes eliminating direct manipulation of SKB lists
          wherever possible, and to always use the appropriate SKB list
          helpers. This work is still ongoing...
      
       7) Lots of PHY driver and state machine improvements and
          simplifications, from Heiner Kallweit.
      
       8) Various TSO deferral refinements, from Eric Dumazet.
      
       9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov.
      
      10) Batch dropping of XDP packets in tuntap, from Jason Wang.
      
      11) Lots of cleanups and improvements to the r8169 driver from Heiner
          Kallweit, including support for ->xmit_more. This driver has been
          getting some much needed love since he started working on it.
      
      12) Lots of new forwarding selftests from Petr Machata.
      
      13) Enable VXLAN learning in mlxsw driver, from Ido Schimmel.
      
      14) Packed ring support for virtio, from Tiwei Bie.
      
      15) Add new Aquantia AQtion USB driver, from Dmitry Bezrukov.
      
      16) Add XDP support to dpaa2-eth driver, from Ioana Ciocoi Radulescu.
      
      17) Implement coalescing on TCP backlog queue, from Eric Dumazet.
      
      18) Implement carrier change in tun driver, from Nicolas Dichtel.
      
      19) Support msg_zerocopy in UDP, from Willem de Bruijn.
      
      20) Significantly improve garbage collection of neighbor objects when
          the table has many PERMANENT entries, from David Ahern.
      
      21) Remove egdev usage from nfp and mlx5, and remove the facility
          completely from the tree as it no longer has any users. From Oz
          Shlomo and others.
      
      22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and
          therefore abort the operation before the commit phase (which is the
          NETDEV_CHANGEADDR event). From Petr Machata.
      
      23) Add indirect call wrappers to avoid retpoline overhead, and use them
          in the GRO code paths. From Paolo Abeni.
      
      24) Add support for netlink FDB get operations, from Roopa Prabhu.
      
      25) Support bloom filter in mlxsw driver, from Nir Dotan.
      
      26) Add SKB extension infrastructure. This consolidates the handling of
          the auxiliary SKB data used by IPSEC and bridge netfilter, and is
          designed to support the needs to MPTCP which could be integrated in
          the future.
      
      27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan.

      Pull selinux patches from Paul Moore:
       "I already used my best holiday pull request lines in the audit pull
        request, so this one is going to be a bit more boring, sorry about
        that. To make up for this, we do have a birthday of sorts to
        celebrate: SELinux turns 18 years old this December. Perhaps not the
        most exciting thing in the world for most people, but I think it's
        safe to say that anyone reading this email doesn't exactly fall into
        the "most people" category.
      
        Back to business and the pull request itself:
      
        Ondrej has five patches in this pull request and I lump them into
        three categories: one patch to always allow submounts (using similar
        logic to elsewhere in the kernel), one to fix some issues with the
        SELinux policydb, and the others to cleanup and improve the SELinux
        sidtab.
      
        The other patches from Alexey and Petr and trivial fixes that are
        adequately described in their respective subject lines.
      
        With this last pull request of the year, I want to thank everyone who
        has contributed patches, testing, and reviews to the SELinux project
        this year, and the past 18 years. Like any good open source effort,
        SELinux is only as good as the community which supports it, and I'm
        very happy that we have the community we do - thank you all!"

        selinux: use separate table for initial SID lookup
        selinux: make "selinux_policycap_names[]" const char *

      Pull audit updates from Paul Moore:
       "In the finest of holiday of traditions, I have a number of gifts to
        share today. While most of them are re-gifts from others, unlike the
        typical re-gift, these are things you will want in and around your
        tree; I promise.
      
        This pull request is perhaps a bit larger than our typical PR, but
        most of it comes from Jan's rework of audit's fanotify code; a very
        welcome improvement. We ran this through our normal regression tests,
        as well as some newly created stress tests and everything looks good.
      
        Richard added a few patches, mostly cleaning up a few things and and
        shortening some of the audit records that we send to userspace; a
        change the userspace folks are quite happy about.
      
        Finally YueHaibing and I kick in a few patches to simplify things a
        bit and make the code less prone to errors.
      
        Lastly, I want to say thanks one more time to everyone who has
        contributed patches, testing, and code reviews for the audit subsystem
        over the past year. The project is what it is due to your help and
        contributions - thank you"

       "Notable changes:
      
         - Mitigations for Spectre v2 on some Freescale (NXP) CPUs.
      
         - A large series adding support for pass-through of Nvidia V100 GPUs
           to guests on Power9.
      
         - Another large series to enable hardware assistance for TLB table
           walk on MPC8xx CPUs.
      
         - Some preparatory changes to our DMA code, to make way for further
           cleanups from Christoph.
      
         - Several fixes for our Transactional Memory handling discovered by
           fuzzing the signal return path.
      
         - Support for generating our system call table(s) from a text file
           like other architectures.
      
         - A fix to our page fault handler so that instead of generating a
           WARN_ON_ONCE, user accesses of kernel addresses instead print a
           ratelimited and appropriately scary warning.
      
         - A cosmetic change to make our unhandled page fault messages more
           similar to other arches and also more compact and informative.
      
         - Freescale updates from Scott:
             "Highlights include elimination of legacy clock bindings use from
              dts files, an 83xx watchdog handler, fixes to old dts interrupt
              errors, and some minor cleanup."

      sched/fair: Fix warning on non-SMP build · 6d101ba6
      Olof Johansson authored
      Caused by making the variable static:
      
        kernel/sched/fair.c:119:21: warning: 'capacity_margin' defined but not used [-Wunused-variable]
      
      Seems easiest to just move it up under the existing ifdef CONFIG_SMP
      that's a few lines above.
      
      Fixes: ed8885a1 ('sched/fair: Make some variables static')
