      Pull irq updates from Thomas Gleixner:
       "The irq departement delivers:
      
         - a cleanup series to get rid of mindlessly copied code.
      
         - another bunch of new pointlessly different interrupt chip drivers.
      
           Adding homebrewn irq chips (and timers) to SoCs must provide a
           value add which is beyond the imagination of mere mortals.
      
         - the usual SoC irq controller updates, IOW my second cat herding
           project"

         - a few fixlets in the NOHZ code

      Pull networking updates from David Miller:
       "Most notable changes in here:
      
         1) By far the biggest accomplishment, thanks to a large range of
            contributors, is the addition of multi-send for transmit.  This is
            the result of discussions back in Chicago, and the hard work of
            several individuals.
      
            Now, when the ->ndo_start_xmit() method of a driver sees
            skb->xmit_more as true, it can choose to defer the doorbell
            telling the driver to start processing the new TX queue entires.
      
            skb->xmit_more means that the generic networking is guaranteed to
            call the driver immediately with another SKB to send.
      
            There is logic added to the qdisc layer to dequeue multiple
            packets at a time, and the handling mis-predicted offloads in
            software is now done with no locks held.
      
            Finally, pktgen is extended to have a "burst" parameter that can
            be used to test a multi-send implementation.
      
            Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
            virtio_net
      
            Adding support is almost trivial, so export more drivers to
            support this optimization soon.
      
            I want to thank, in no particular or implied order, Jesper
            Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
            Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
            David Tat, Hannes Frederic Sowa, and Rusty Russell.
      
         2) PTP and timestamping support in bnx2x, from Michal Kalderon.
      
         3) Allow adjusting the rx_copybreak threshold for a driver via
            ethtool, and add rx_copybreak support to enic driver.  From
            Govindarajulu Varadarajan.
      
         4) Significant enhancements to the generic PHY layer and the bcm7xxx
            driver in particular (EEE support, auto power down, etc.) from
            Florian Fainelli.
      
         5) Allow raw buffers to be used for flow dissection, allowing drivers
            to determine the optimal "linear pull" size for devices that DMA
            into pools of pages.  The objective is to get exactly the
            necessary amount of headers into the linear SKB area pre-pulled,
            but no more.  The new interface drivers use is eth_get_headlen().
            From WANG Cong, with driver conversions (several had their own
            by-hand duplicated implementations) by Alexander Duyck and Eric
            Dumazet.
      
         6) Support checksumming more smoothly and efficiently for
            encapsulations, and add "foo over UDP" facility.  From Tom
            Herbert.
      
         7) Add Broadcom SF2 switch driver to DSA layer, from Florian
            Fainelli.
      
         8) eBPF now can load programs via a system call and has an extensive
            testsuite.  Alexei Starovoitov and Daniel Borkmann.
      
         9) Major overhaul of the packet scheduler to use RCU in several major
            areas such as the classifiers and rate estimators.  From John
            Fastabend.
      
        10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
            Duyck.
      
        11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
            Dumazet.
      
        12) Add Datacenter TCP congestion control algorithm support, From
            Florian Westphal.
      
        13) Reorganize sk_buff so that __copy_skb_header() is significantly
            faster.  From Eric Dumazet"

      Pull ARM64 SoC changes from Arnd Bergmann:
       "Starting with 3.18, we are merging SoC-specific changes for arm64
        through the arm-soc tree, like we have been doing for arm32.
      
        This time, there is only one set of changes, adding support for the
        Cavium "Thunder" Soc family.  Since the changes are relatively small,
        this includes Kconfig, defconfig and DT changes.
      
        If all goes well, we will never require adding actual C source code
        for platform support in arm64, given that the architecture is more
        clearly defined and we have moved out a lot of the platform specifics
        into device drivers for arm32 already"
