      Pull networking fixes from David S. Miller:
      
       1) Since we do RCU lookups on ipv4 FIB entries, we have to test if the
          entry is dead before returning it to our caller.
      
       2) openvswitch locking and packet validation fixes from Ansis Atteka,
          Jesse Gross, and Pravin B Shelar.
      
       3) Fix PM resume locking in IGB driver, from Benjamin Poirier.
      
       4) Fix VLAN header handling in vhost-net and macvtap, from Basil Gor.
      
       5) Revert a bogus network namespace isolation change that was causing
          regressions on S390 networking devices.
      
       6) If bonding decides to process and handle a LACPDU frame, we
          shouldn't bump the rx_dropped counter.  From Jiri Bohac.
      
       7) Fix mis-calculation of available TX space in r8169 driver when doing
          TSO, which can lead to crashes and/or hung device.  From Julien
          Ducourthial.
      
       8) SCTP does not validate cached routes properly in all cases, from
          Nicolas Dichtel.
      
       9) Link status interrupt needs to be handled in ks8851 driver, from
          Stephen Boyd.
      
      10) Use capable(), not cap_raised(), in connector/userns netlink code.
          From Eric W. Biederman via Andrew Morton.
      
      11) Fix pktgen OOPS on module unload, from Eric Dumazet.
      
      12) iwlwifi under-estimates SKB truesizes, also from Eric Dumazet.
      
      13) Cure division by zero in SFC driver, from Ben Hutchings.

      dm thin: fix unprotected use of prepared_discards list · c3a0ce2e
      Mike Snitzer authored
      Fix two places in commit 104655fd ("dm thin: support discards") that
      didn't use pool->lock to protect against concurrent changes to the
      prepared_discards list.
      
      Without this fix, thin_endio() can race with process_discard(), leading
      to concurrent list_add()s that result in the processes locking up with
      an error like the following:

      simplification of cell_release_singleton() in commit
      6f94a4c4 ("dm thin: fix stacked bi_next
      usage").
      
      A cell's hlist_del() must be accompanied by a mempool_free().
      Use __cell_release() to do this, like before.

      parisc: move definition of PAGE0 to asm/page.h · 4a8a0788
      Rolf Eike Beer authored
      This was defined in asm/pdc.h which needs to include asm/page.h for
      __PAGE_OFFSET. This leads to an include loop so that page.h eventually will
      include pdc.h again. While this is no problem because of header guards, it is
      a problem because some symbols may be undefined. Such an error is this:
