       "This pull request is later than I'd have liked because I was waiting
        for some performance data to help finally justify sending the

        Unfortunately we came up short, so those dm-crypt changes will
        continue to wait, but it seems we're not far off.
      
         . Add dm_accept_partial_bio interface to DM core to allow DM targets
           to only process a portion of a bio, the remainder being sent in the
           next bio.  This enables the old dm snapshot-origin target to only
           split write bios on chunk boundaries, read bios are now sent to the
           origin device unchanged.
      
         . Add DM core support for disabling WRITE SAME if the underlying SCSI
           layer disables it due to command failure.
      
         . Reduce lock contention in DM's bio-prison.

      Pull more ACPI and power management updates from Rafael Wysocki:
       "These are fixups on top of the previous PM+ACPI pull request,
        regression fixes (ACPI hotplug, cpufreq ppc-corenet), other bug fixes
        (ACPI reset, cpufreq), new PM trace points for system suspend
        profiling and a copyright notice update.
      
        Specifics:
      
         - I didn't remember correctly that the Hans de Goede's ACPI video
           patches actually didn't flip the video.use_native_backlight
           default, although we had discussed that and decided to do that.
           Since I said we would do that in the previous PM+ACPI pull request,
           make that change for real now.
      
         - ACPI bus check notifications for PCI host bridges don't cause the
           bus below the host bridge to be checked for changes as they should
           because of a mistake in the ACPI-based PCI hotplug (ACPIPHP)
           subsystem that forgets to add hotplug contexts to PCI host bridge
           ACPI device objects.  Create hotplug contexts for PCI host bridges
           too as appropriate.

      rtnetlink: fix userspace API breakage for iproute2 < v3.9.0 · e5eca6d4
      Michal Schmidt authored
      When running RHEL6 userspace on a current upstream kernel, "ip link"
      fails to show VF information.
      
      The reason is a kernel<->userspace API change introduced by commit
      88c5b5ce ("rtnetlink: Call nlmsg_parse() with correct header length"),
      after which the kernel does not see iproute2's IFLA_EXT_MASK attribute
      in the netlink request.
      
      iproute2 adjusted for the API change in its commit 63338dca4513
      ("libnetlink: Use ifinfomsg instead of rtgenmsg in rtnl_wilddump_req_filter").
      
      The problem has been noticed before:
      http://marc.info/?l=linux-netdev&m=136692296022182&w=2
      (Subject: Re: getting VF link info seems to be broken in 3.9-rc8)
      
      We can do better than tell those with old userspace to upgrade. We can
      recognize the old iproute2 in the kernel by checking the netlink message
      length. Even when including the IFLA_EXT_MASK attribute, its netlink
      message is shorter than struct ifinfomsg.
      
      With this patch "ip link" shows VF information in both old and new
      iproute2 versions.

      FEC HW support IP header and TCP/UDP hw checksum, support multi buffer descriptor transfer
      one frame, but don't support HW TSO. And imx6q/dl SOC FEC Gbps speed has HW bus Bandwidth
      limitation (400Mbps ~ 700Mbps), imx6sx SOC FEC Gbps speed has no HW bandwidth limitation.
      
      The patch set just enable TSO feature, which is done following the mv643xx_eth driver.
      
      Test result analyze:
      imx6dl sabresd board: there have 82% improvement, since imx6dl FEC HW has bandwidth limitation,
                            the performance with SW TSO is a milestone.
      
      Addition test:
      imx6sx sdb board:
      upstream still don't support imx6sx due to some patches being upstream... they use same FEC IP.
      Use the SW TSO patches test imx6sx sdb board in internal kernel tree:
      No SW TSO patch: tx bandwidth 840Mbps, cpu loading is 100%.
      SW TSO patch:    tx bandwidth 942Mbps, cpu loading is 65%.
      It means the patch set have great improvement for imx6sx FEC performance.
      
      V2:
      * From Frank Li's suggestion:
      	Change the API "fec_enet_txdesc_entry_free" name to "fec_enet_get_free_txdesc_num".
      * Summary David Laight and Eric Dumazet's thoughts:
      	RX BD entry number change to 256.
      * From ezequiel's suggestion:
      	Follow the latest TSO fixes from his solution to rework the queue stop/wake-up.
      	Avoid unmapping the TSO header buffers.
      * From Eric Dumazet's suggestion:
      	Avoid more bytes copy, just copying the unaligned part of the payload into first
      	descriptor. The suggestion will bring more complex for the driver, and imx6dl FEC
      	DMA need 16 bytes alignment, but cpu loading is not problem that cpu loading is
      	30%, the current performance is so better. Later chip like imx6sx Gigbit FEC DMA
      	support byte alignment, so there don't exist memory copy. So, the V2 version drop
      	the suggestion.
      	Anyway, thanks for Eric's response and suggestion.
      
      V3:
      * From David Laight's feedback:
      	Decide to drop RX BD entry number change for the SW TSO patch set.
      	I will generate one separate patch to increase RX BDs entry for interrupt coalescing feature which
      	will be supported in my later patch set.
      
      V4:
      * From David Laight's feedback:
      	Remove the conditional in .fec_enet_get_bd_index().
      
      V5:
      * Patch #4 update:
        From David Laight's feedback:
      	"expect fec_enet_get_free_txdesc_num() to return one less than it does currently."
      	Change the function:
      	Return space available, 0..size-1.  it always leave one free entry. Which is same as linux circ_buf.
      
      Thanks for Eric and ezequiel's help and idea.

      net: fec: Enable IP header hardware checksum · 96c50caa
      Nimrod Andy authored
      IP header checksum is calcalated by network layer in default.
      To support software TSO, it is better to use HW calculate the
      IP header checksum.
      
      FEC hw checksum feature request the checksum field in frame
      is zero, otherwise the calculative CRC is not correct.
      
      For segmentated TCP packet, HW calculate the IP header checksum again,
      it doesn't bring any impact. For SW TSO, HW calculated checksum bring
      better performance.

      Make the code more readable and easy to support other features like
      SG, TSO, moving the common transmit function to one api.
      
      And the patch also factorize the getting BD index to it own function.

      Some fields in "struct net_bridge" aren't available when compiling the
      kernel without IPv6 support. Therefore adding a check/macro to skip the
      complaining code sections in that case.

      bridge: fix smatch warning / potential null pointer dereference · 6c03ee8b
      Linus Lüssing authored
      "New smatch warnings:
        net/bridge/br_multicast.c:1368 br_ip6_multicast_query() error:
          we previously assumed 'group' could be null (see line 1349)"
      
      In the rare (sort of broken) case of a query having a Maximum
      Response Delay of zero, we could create a potential null pointer
      dereference.
      
      Fixing this by skipping the multicast specific MLD Query parsing again
      if no multicast group address is available.

      when forcing 100 full-duplex with autoneg disable.

      bnx2x: Enlarge the dorq threshold for VFs · f2cfa997
      Ariel Elior authored
      A malicious VF might try to starve the other VFs & PF by creating
      contineous doorbell floods. In order to negate this, HW has a threshold of
      doorbells per client, which will stop the client doorbells from arriving
      if crossed.
      
      The threshold currently configured for VFs is too low - under extreme traffic
      scenarios, it's possible for a VF to reach the threshold and thus for its
      fastpath to stop working.

      sctp: Fix sk_ack_backlog wrap-around problem · d3217b15
      Xufeng Zhang authored
      Consider the scenario:
      For a TCP-style socket, while processing the COOKIE_ECHO chunk in
      sctp_sf_do_5_1D_ce(), after it has passed a series of sanity check,
      a new association would be created in sctp_unpack_cookie(), but afterwards,
      some processing maybe failed, and sctp_association_free() will be called to
      free the previously allocated association, in sctp_association_free(),
      sk_ack_backlog value is decremented for this socket, since the initial
      value for sk_ack_backlog is 0, after the decrement, it will be 65535,
      a wrap-around problem happens, and if we want to establish new associations
      afterward in the same socket, ABORT would be triggered since sctp deem the
      accept queue as full.
      Fix this issue by only decrementing sk_ack_backlog for associations in
      the endpoint's list.
