      Pull Xen update from Konrad Rzeszutek Wilk:
       "Features:
         * Performance improvement to lower the amount of traps the hypervisor
           has to do 32-bit guests.  Mainly for setting PTE entries and
           updating TLS descriptors.
         * MCE polling driver to collect hypervisor MCE buffer and present
           them to /dev/mcelog.
         * Physical CPU online/offline support.  When an privileged guest is
           booted it is present with virtual CPUs, which might have an 1:1 to
           physical CPUs but usually don't.  This provides mechanism to
           offline/online physical CPUs.
        Bug-fixes for:
         * Coverity found fixes in the console and ACPI processor driver.
         * PVonHVM kexec fixes along with some cleanups.
         * Pages that fall within E820 gaps and non-RAM regions (and had been
           released to hypervisor) would be populated back, but potentially in
           non-RAM regions."

      Pull networking changes from David S Miller:
      
       1) Remove the ipv4 routing cache.  Now lookups go directly into the FIB
          trie and use prebuilt routes cached there.
      
          No more garbage collection, no more rDOS attacks on the routing
          cache.  Instead we now get predictable and consistent performance,
          no matter what the pattern of traffic we service.
      
          This has been almost 2 years in the making.  Special thanks to
          Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
          have helped along the way.
      
          I'm sure that with a change of this magnitude there will be some
          kind of fallout, but such things ought the be simple to fix at this
          point.  Luckily I'm not European so I'll be around all of August to
          fix things :-)
      
          The major stages of this work here are each fronted by a forced
          merge commit whose commit message contains a top-level description
          of the motivations and implementation issues.
      
       2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
          input.
      
       3) TCP SYN/ACK performance tweaks from Eric Dumazet.
      
       4) Add namespace support for netfilter L4 conntrack helpers, from Gao
          Feng.
      
       5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
          Yuval Mintz.
      
       6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.
      
       7) Support for connection tracker helpers in userspace, from Pablo
          Neira Ayuso.
      
       8) Allow userspace driven TX load balancing functions in TEAM driver,
          from Jiri Pirko.
      
       9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
          embedded gotos.
      
      10) TCP Small Queues, essentially minimize the amount of TCP data queued
          up in the packet scheduler layer.  Whereas the existing BQL (Byte
          Queue Limits) limits the pkt_sched --> netdevice queuing levels,
          this controls the TCP --> pkt_sched queueing levels.
      
          From Eric Dumazet.
      
      11) Reduce the number of get_page/put_page ops done on SKB fragments,
          from Alexander Duyck.
      
      12) Implement protection against blind resets in TCP (RFC 5961), from
          Eric Dumazet.
      
      13) Support the client side of TCP Fast Open, basically the ability to
          send data in the SYN exchange, from Yuchung Cheng.
      
          Basically, the sender queues up data with a sendmsg() call using
          MSG_FASTOPEN, then they do the connect() which emits the queued up
          fastopen data.
      
      14) Avoid all the problems we get into in TCP when timers or PMTU events
          hit a locked socket.  The TCP Small Queues changes added a
          tcp_release_cb() that allows us to queue work up to the
          release_sock() caller, and that's what we use here too.  From Eric
          Dumazet.
      
      15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.
