      Pull NFS client bugfixes from Trond Myklebust:
      
       - Fix an Oops in the pNFS layoutget code
      
       - Fix a number of NFSv4 and v4.1 state recovery deadlocks and hangs due
         to the interaction of the session drain lock and state management
         locks.
      
       - Remove task->tk_xprt, which was hiding a lot of RCU dereferencing
         bugs
      
       - Fix a long standing NFSv3 posix lock recovery bug.
      
       - Revert commit 324d003b ("NFS: add nfs_sb_deactive_async to avoid
         deadlock").  It turned out that the root cause of the deadlock was
         due to interactions with the workqueues that have now been resolved.

      Pull GFS2 updates from Steven Whitehouse:
       "This is one of the smallest collections of patches for the merge
        window for some time.  There are some clean ups relating to the
        transaction code and the shrinker, which are mostly in preparation for
        further development, but also make the code much easier to follow in
        these areas.
      
        There is a patch which allows the use of ->writepages even in the
        default ordered write mode for all writebacks.  This results in
        sending larger i/os to the block layer, and a subsequent increase in
        performance.  It also reduces the number of different i/o paths by
        one.
      
        There is also a bug fix reinstating the withdraw ack system which
        somehow got lost when the lock modules were merged into GFS2."

      KEYS: Revert one application of "Fix unreachable code" patch · fe9453a1
      David Howells authored
      A patch to fix some unreachable code in search_my_process_keyrings() got
      applied twice by two different routes upstream as commits e67eab39
      and b010520a (both "fix unreachable code").
      
      Unfortunately, the second application removed something it shouldn't
      have and this wasn't detected by GIT.  This is due to the patch not
      having sufficient lines of context to distinguish the two places of
      application.
      
      The effect of this is relatively minor: inside the kernel, the keyring
      search routines may search multiple keyrings and then prioritise the
      errors if no keys or negative keys are found in any of them.  With the
      extra deletion, the presence of a negative key in the thread keyring
      (causing ENOKEY) is incorrectly overridden by an error searching the
      process keyring.
      
      So revert the second application of the patch.

      Pull networking update from David Miller:
      
       1) Checkpoint/restarted TCP sockets now can properly propagate the TCP
          timestamp offset.  From Andrey Vagin.
      
       2) VMWARE VM VSOCK layer, from Andy King.
      
       3) Much improved support for virtual functions and SR-IOV in bnx2x,
          from Ariel ELior.
      
       4) All protocols on ipv4 and ipv6 are now network namespace aware, and
          all the compatability checks for initial-namespace-only protocols is
          removed.  Thanks to Tom Parkin for helping deal with the last major
          holdout, L2TP.
      
       5) IPV6 support in netpoll and network namespace support in pktgen,
          from Cong Wang.
      
       6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration
          Protocol (MVRP) support, from David Ward.
      
       7) Compute packet lengths more accurately in the packet scheduler, from
          Eric Dumazet.
      
       8) Use per-task page fragment allocator in skb_append_datato_frags(),
          also from Eric Dumazet.
      
       9) Add support for connection tracking labels in netfilter, from
          Florian Westphal.
      
      10) Fix default multicast group joining on ipv6, and add anti-spoofing
          checks to 6to4 and 6rd.  From Hannes Frederic Sowa.
      
      11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern
          times, rearrange inet frag datastructures for better cacheline
          locality, and move more operations outside of locking.  From Jesper
          Dangaard Brouer.
      
      12) Instead of strict master <--> slave relationships, allow arbitrary
          scenerios with "upper device lists".  From Jiri Pirko.
      
      13) Improve rate limiting accuracy in TBF and act_police, also from Jiri
          Pirko.
      
      14) Add a BPF filter netfilter match target, from Willem de Bruijn.
      
      15) Orphan and delete a bunch of pre-historic networking drivers from
          Paul Gortmaker.
      
      16) Add TSO support for GRE tunnels, from Pravin B SHelar.  Although
          this still needs some minor bug fixing before it's %100 correct in
          all cases.
      
      17) Handle unresolved IPSEC states like ARP, with a resolution packet
          queue.  From Steffen Klassert.
      
      18) Remove TCP Appropriate Byte Count support (ABC), from Stephen
          Hemminger.  This was long overdue.
      
      19) Support SO_REUSEPORT, from Tom Herbert.
      
      20) Allow locking a socket BPF filter, so that it cannot change after a
          process drops capabilities.
      
      21) Add VLAN filtering to bridge, from Vlad Yasevich.
      
      22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in
          the ipv6 routes, from YOSHIFUJI Hideaki.

      sparc64: Fix huge PMD to PTE translation for sun4u in TLB miss handler. · 76968ad2
      David S. Miller authored
      When we set the sun4u version of the PTE execute bit, it's:
      
      	or	REG, _PAGE_EXEC_4U, REG
      
      _PAGE_EXEC_4U is 0x1000, unfortunately the immedate field of the
      'or' instruction is a signed 13-bit value.  So the above actually
      assembles into:
      
      	or	REG, -4096, REG
      
      completely corrupting the final PTE value.
      
      Set it with a:
      
      	sethi	%hi(_PAGE_EXEC_4U), TMP
      	or	REG, TMP, REG
      
      sequence instead.
      
      This fixes "git gc" crashes on sun4u machines.

      | stuff added in commit 1716a961
      | (ipv6: fix problem with expired dst cache)
      | are racy : same dst could be manipulated at the same time

      |
      | At some point, our stack believes rt->dst.from contains a dst pointer,

      |
      | rt6_update_expires() should be fixed, or am I missing something ?
      |
      | CC Neil because of https://bugzilla.redhat.com/show_bug.cgi?id=892060
      
      Because we do not have any locks for dst_entry, we cannot change
      essential structure in the entry; e.g., we cannot change reference
      to other entity.
      
      To fix this issue, split 'from' and 'expires' field in dst_entry
      out of union.  Once it is 'from' is assigned in the constructor,
      keep the reference until the very last stage of the life time of
      the object.
      
      Of course, it is unsafe to change 'from', so make rt6_set_from simple
      just for fresh entries.

      commit c9af6db4 (net: Fix possible wrong checksum generation)
      has a suspicous piece:
      
      	-       skb_shinfo(skb1)->gso_type = skb_shinfo(skb)->gso_type;
      	-
      	+       skb_shinfo(skb)->tx_flags = skb_shinfo(skb1)->tx_flags & SKBTX_SHARED_FRAG;
      
      skb1 is the new skb, therefore should be on the left side of the assignment.
      This patch fixes it.

           This is Android Emulator battery driver.  Originally from Google,

         - pm2301_charger:
      
           A new driver for ST-Ericsson 2301 Power Management chip, uses
           AB8500 battery management core
      
         - qnap-poweroff:
      
           The driver adds poweroff functionality for QNAP NAS boxes
      
         - restart-poweroff:
      
           A generic driver that implements 'power off by restarting'.  The
           actual poweroff functionality is implemented through a bootloader,
           so Linux' task is just to restart the box.  The driver is useful on
           Buffalo Linkstation LS-XHL and LS-CHLv2 boards.  Andrew Lunn worked
           on submitting the driver (as well as qnap-poweroff above).
      
        Additionally:
      
         - A lot of fixes for ab8500 drivers.  This is a part of efforts of
           syncing internal ST-Ericsson development tree with the mainline.
           Lee Jones @ Linaro worked on compilation and reshaping these
           series.
      
         - New health properties for the power supplies: "Watchdog timer
           expire" and "Safety timer expire"

      sparc64: Fix tsb_grow() in atomic context. · 0fbebed6
      David S. Miller authored
      If our first THP installation for an MM is via the set_pmd_at() done
      during khugepaged's collapsing we'll end up in tsb_grow() trying to do
      a GFP_KERNEL allocation with several locks held.
      
      Simply using GFP_ATOMIC in this situation is not the best option
      because we really can't have this fail, so we'd really like to keep
      this an order 0 GFP_KERNEL allocation if possible.
      
      Also, doing the TSB allocation from khugepaged is a really bad idea
      because we'll allocate it potentially from the wrong NUMA node in that
      context.
      
      So what we do is defer the hugepage TSB allocation until the first TLB
      miss we take on a hugepage.  This is slightly tricky because we have
      to handle two unusual cases:
      
      1) Taking the first hugepage TLB miss in the window trap handler.
         We'll call the winfix_trampoline when that is detected.
      
      2) An initial TSB allocation via TLB miss races with a hugetlb
         fault on another cpu running the same MM.  We handle this by
         unconditionally loading the TSB we see into the current cpu
         even if it's non-NULL at hugetlb_setup time.

      David S. Miller authored
      Accomodate the possibility that the TSB might be NULL at
      the point that update_mmu_cache() is invoked.  This is
      necessary because we will sometimes need to defer the TSB
      allocation to the first fault that happens in the 'mm'.
      
      Seperate out the hugepage PTE test into a seperate function
      so that the logic is clearer.
