      Pull IOMMU updates from Joerg Roedel:
       "The most important part of these updates is the IOMMU groups code
        enhancement written by Alex Williamson.  It abstracts the problem that
        a given hardware IOMMU can't isolate any given device from any other
        device (e.g.  32 bit PCI devices can't usually be isolated).  Devices
        that can't be isolated are grouped together.  This code is required
        for the upcoming VFIO framework.
      
        Another IOMMU-API change written by me is the introduction of domain
        attributes.  This makes it easier to handle GART-like IOMMUs with the
        IOMMU-API because now the start-address and the size of the domain
        address space can be queried.
      
        Besides that there are a few cleanups and fixes for the NVidia Tegra
        IOMMU drivers and the reworked init-code for the AMD IOMMU.  The
        latter is from my patch-set to support interrupt remapping.  The rest
        of this patch-set requires x86 changes which are not mergabe yet.  So
        full support for interrupt remapping with AMD IOMMUs will come in a
        future merge window."

          uhid is for the other (transport) part of the pipeline).
      
          It's needed for (and currently being used by) Bluetooth-LowEnergy,
          as its specification mandates things we don't want in the kernel.
      
          Written by David Herrmann.

          (probably never reported to actually happen in the wild, but still).

           booted it is present with virtual CPUs, which might have an 1:1 to
           physical CPUs but usually don't.  This provides mechanism to

      ARM: tegra: harmony: add regulator supply name and its input supply · 3d55c29f
      Laxman Dewangan authored
      Name the regulator as per board schematics and adds its
      supply name info in regulator data.
      Add the always on fixed regulator to refer the battery supply.
      
      Use this fixed regulator for input supply of some of PMIC
      regulator
      
      This patch was originally part of a 2-patch series. Patch 2 got applied
      to the regulator tree as 7c7fac30
      
       "regulator: tps6586x: add support for
      input supply" without this patch. This broke regulator support on
      Harmony.

      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.

      i2c: Fall back to emulated SMBus if the operation isn't supported natively · 72fc2c7f
      Laurent Pinchart authored
      
      
      Adapter drivers might support only a subset of the SMBus operations
      natively. Those drivers currently have to manually emulate unsupported
      operations using I2C.
      
      Make the i2c_smbus_xfer() function fall back to
      i2c_smbus_xfer_emulated() when the adapter's .smbus_xfer() operation
      returns -EOPNOTSUPP, like it already does when the .smbus_xfer()
      operation isn't available at all.

      i2c: Add SCCB support · d47726c5
      Laurent Pinchart authored
      
      
      SCCB is a serial communication bus developed by Omnivision. Its 2-wire
      mode is very similar to SMBus byte data transactions, but requires the
      controller to ignore the ACK bit and to insert a stop condition after
      each message.
      
      Add a device SCCB flag and a message stop flag to be passed to
      controller drivers.

      i2c-tiny-usb: Add support for the Robofuzz OSIF USB/I2C converter · 68a7602f
      Emmanuel Deloget authored
      
      
      Robofuzz OSIF is a generic USB/iIC interface that embeds an ATMega8A
      AVR-RISC microcontroler.
      
      The device is based upon Till Harbaum's i2c-tiny-usb and although it
      enhances the original design with further functionnalities it still
      maintain compatibility with it with respect to the USB/I2C interface.

      i2c-i801: Enable IRQ for byte_by_byte transactions · d3ff6ce4
      Daniel Kurtz authored
      
      
      Byte-by-byte transactions are used primarily for accessing I2C devices
      with an SMBus controller.  For these transactions, for each byte that is
      read or written, the SMBus controller generates a BYTE_DONE IRQ.  The isr
      reads/writes the next byte, and clears the IRQ flag to start the next byte.
      On the penultimate IRQ, the isr also sets the LAST_BYTE flag.
      
      There is no locking around the cmd/len/count/data variables, since the
      I2C adapter lock ensures there is never multiple simultaneous transactions
      for the same device, and the driver thread never accesses these variables
      while interrupts might be occurring.
      
      The end result is faster I2C block read and write transactions.
      
      Note: This patch has only been tested and verified by doing I2C read and
      write block transfers on Cougar Point 6 Series PCH, as well as I2C read
      block transfers on ICH5.
