         - A conversion to the devm_* API for most of the MFD drivers.
         - The twl4030-power got split from twl-core into its own module.
         - A major ti_am335x_adc cleanup, leading to a proper DT support.
         - Our regular arizona and wm* updates and cleanups from the Wolfson

      Pull networking updates from David Miller:
       "This is a re-do of the net-next pull request for the current merge
        window.  The only difference from the one I made the other day is that
        this has Eliezer's interface renames and the timeout handling changes
        made based upon your feedback, as well as a few bug fixes that have
        trickeled in.
      
        Highlights:
      
         1) Low latency device polling, eliminating the cost of interrupt
            handling and context switches.  Allows direct polling of a network
            device from socket operations, such as recvmsg() and poll().
      
            Currently ixgbe, mlx4, and bnx2x support this feature.
      
            Full high level description, performance numbers, and design in
            commit 0a4db187 ("Merge branch 'll_poll'")
      
            From Eliezer Tamir.
      
         2) With the routing cache removed, ip_check_mc_rcu() gets exercised
            more than ever before in the case where we have lots of multicast
            addresses.  Use a hash table instead of a simple linked list, from
            Eric Dumazet.
      
         3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
            Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
            Marek Puzyniak, Michal Kazior, and Sujith Manoharan.
      
         4) Support reporting the TUN device persist flag to userspace, from
            Pavel Emelyanov.
      
         5) Allow controlling network device VF link state using netlink, from
            Rony Efraim.
      
         6) Support GRE tunneling in openvswitch, from Pravin B Shelar.
      
         7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
            Daniel Borkmann and Eric Dumazet.
      
         8) Allow controlling of TCP quickack behavior on a per-route basis,
            from Cong Wang.
      
         9) Several bug fixes and improvements to vxlan from Stephen
            Hemminger, Pravin B Shelar, and Mike Rapoport.  In particular,
            support receiving on multiple UDP ports.
      
        10) Major cleanups, particular in the area of debugging and cookie
            lifetime handline, to the SCTP protocol code.  From Daniel
            Borkmann.
      
        11) Allow packets to cross network namespaces when traversing tunnel
            devices.  From Nicolas Dichtel.
      
        12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
            manner akin to how we monitor real network traffic via ptype_all.
            From Daniel Borkmann.
      
        13) Several bug fixes and improvements for the new alx device driver,
            from Johannes Berg.
      
        14) Fix scalability issues in the netem packet scheduler's time queue,
            by using an rbtree.  From Eric Dumazet.
      
        15) Several bug fixes in TCP loss recovery handling, from Yuchung
            Cheng.
      
        16) Add support for GSO segmentation of MPLS packets, from Simon
            Horman.
      
        17) Make network notifiers have a real data type for the opaque
            pointer that's passed into them.  Use this to properly handle
            network device flag changes in arp_netdev_event().  From Jiri
            Pirko and Timo Teräs.
      
        18) Convert several drivers over to module_pci_driver(), from Peter

       "Okay this is the big one, I was stalled on the fbdev pull req as I
        stupidly let fbdev guys merge a patch I required to fix a warning with
        some patches I had, they ended up merging the patch from the wrong
        place, but the warning should be fixed.  In future I'll just take the
        patch myself!
      
        Outside drm:
      
        There are some snd changes for the HDMI audio interactions on haswell,
        they've been acked for inclusion via my tree.  This relies on the
        wound/wait tree from Ingo which is already merged.
      
        Major changes:
      
        AMD finally released the dynamic power management code for all their
        GPUs from r600->present day, this is great, off by default for now but
        also a huge amount of code, in fact it is most of this pull request.
      
        Since it landed there has been a lot of community testing and Alex has
        sent a lot of fixes for any bugs found so far.  I suspect radeon might
        now be the biggest kernel driver ever :-P p.s.  radeon.dpm=1 to enable
        dynamic powermanagement for anyone.
      
        New drivers:
      
        Renesas r-car display unit.
      
        Other highlights:
      
         - core: GEM CMA prime support, use new w/w mutexs for TTM
           reservations, cursor hotspot, doc updates
         - dvo chips: chrontel 7010B support
         - i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
           Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
           support (this time for sure)
         - nouveau: async buffer object deletion, context/register init
           updates, kernel vp2 engine support, GF117 support, GK110 accel
           support (with external nvidia ucode), context cleanups.
         - exynos: memory leak fixes, Add S3C64XX SoC series support, device
           tree updates, common clock framework support,
         - qxl: cursor hotspot support, multi-monitor support, suspend/resume
           support
         - mgag200: hw cursor support, g200 mode limiting
         - shmobile: prime support
         - tegra: fixes mostly
      
        I've been banging on this quite a lot due to the size of it, and it
        seems to okay on everything I've tested it on."

      Reason for this crash is a gcc miscompilation in the fault handlers of
      pa_memcpy() which return the fault address instead of the copied bytes.
      Since this seems to be a generic problem with gcc-4.7.x (and below), it's
      better to simplify the fault handlers in pa_memcpy to avoid this problem.
      
      Here is a simple reproducer for the problem:
      
      int main(int argc, char **argv)
      {
      	int fd, nbytes;
      	struct iovec wr_iovec[] = {
      		{ "TEST STRING                     ",32},
      		{ (char*)0x40005000,32} }; // random memory.
      	fd = open(DATA_FILE, O_RDWR | O_CREAT, 0666);
      	nbytes = writev(fd, wr_iovec, 2);
      	printf("return value = %d, errno %d (%s)\n",
      		nbytes, errno, strerror(errno));
      	return 0;
      }
      
      In addition, John David Anglin wrote:
      There is no gcc PR as pa_memcpy is not legitimate C code. There is an
      implicit assumption that certain variables will contain correct values
      when an exception occurs and the code randomly jumps to one of the
      exception blocks.  There is no guarantee of this.  If a PR was filed, it
      would likely be marked as invalid.

      parisc: Ensure volatile space register %sr1 is not clobbered · e8d8fc21
      John David Anglin authored
      I still see the occasional random segv on rp3440.  Looking at one of
      these (a code 15), it appeared the problem must be with the cache
      handling of anonymous pages.  Reviewing this, I noticed that the space
      register %sr1 might be being clobbered when we flush an anonymous page.
      
      Register %sr1 is used for TLB purges in a couple of places.  These
      purges are needed on PA8800 and PA8900 processors to ensure cache
      consistency of flushed cache lines.
      
      The solution here is simply to move the %sr1 load into the TLB lock
      region needed to ensure that one purge executes at a time on SMP
      systems.  This was already the case for one use.  After a few days of
      operation, I haven't had a random segv on my rp3440.

      The LMMIO length reported by PAT and the length given by the LBA MASK

      rtnl_is_locked() doesn't check who holds this lock, it just tells that it's

      then it should release net device in other context because there is no way
      to grab rtnl_lock without deadlock.

      Michael S. Tsirkin authored
      vhost_net_ubuf_put_and_wait has a confusing name:
      it will actually also free it's argument.
      Thus since commit 1280c27f
          "vhost-net: flush outstanding DMAs on memory change"
      vhost_net_flush tries to use the argument after passing it
      to vhost_net_ubuf_put_and_wait, this results
      in use after free.
      To fix, don't free the argument in vhost_net_ubuf_put_and_wait,
      add an new API for callers that want to free ubufs.

      net: mv643xx_eth: do not use port number as platform device id · 785bf6f7
      Jonas Gorski authored
      The port number is only local to the ethernet block, not global, so
      there can be two ethernet blocks both using the same port, like
      kirkwood with both using port 0.
      
      Fix this by using the array index offset for the allocated platform
      devices as the id.

      net: sctp: confirm route during forward progress · 8c2f414a
      Daniel Borkmann authored
      This fix has been proposed originally by Vlad Yasevich. He says:
      
        When SCTP makes forward progress (receives a SACK that acks new chunks,
        renegs, or answeres 0-window probes) or when HB-ACK arrives, mark
        the route as confirmed so we don't unnecessarily send NUD probes.
      
      Having a simple SCTP client/server that exchange data chunks every 1sec,
      without this patch ARP requests are sent periodically every 40-60sec.
      With this fix applied, an ARP request is only done once right at the
      "session" beginning. Also, when clearing the related ARP cache entry
      manually during the session, a new request is correctly done. I have
      only "backported" this to net-next and tested that it works, so full
      credit goes to Vlad.

      virtio_net: fix race in RX VQ processing · e1d6fbc3
      David S. Miller authored
      Michael S. Tsirkin says:
      
      ====================
      Jason Wang reported a race in RX VQ processing:
      virtqueue_enable_cb is called outside napi lock,
      violating virtio serialization rules.
      The race has been there from day 1, but it got especially nasty in 3.0
      when commit a5c262c5
      "virtio_ring: support event idx feature"
      added more dependency on vq state.
      
      Please review, and consider for 3.11 and stable.
      
      Changes from v1:
      	- Added Jason's Tested-by tag
      	- minor coding style fix

      virtio_net: fix race in RX VQ processing · cbdadbbf
      Michael S. Tsirkin authored
      virtio net called virtqueue_enable_cq on RX path after napi_complete, so
      with NAPI_STATE_SCHED clear - outside the implicit napi lock.
      This violates the requirement to synchronize virtqueue_enable_cq wrt
      virtqueue_add_buf.  In particular, used event can move backwards,
      causing us to lose interrupts.
      In a debug build, this can trigger panic within START_USE.
      
      Jason Wang reports that he can trigger the races artificially,
      by adding udelay() in virtqueue_enable_cb() after virtio_mb().
      
      However, we must call napi_complete to clear NAPI_STATE_SCHED before
      polling the virtqueue for used buffers, otherwise napi_schedule_prep in
      a callback will fail, causing us to lose RX events.
      
      To fix, call virtqueue_enable_cb_prepare with NAPI_STATE_SCHED
      set (under napi lock), later call virtqueue_poll with
      NAPI_STATE_SCHED clear (outside the lock).

      virtio: support unlocked queue poll · cc229884
      Michael S. Tsirkin authored
      This adds a way to check ring empty state after enable_cb outside any
      locks. Will be used by virtio_net.
      
      Note: there's room for more optimization: caller is likely to have a
      memory barrier already, which means we might be able to get rid of a
      barrier here.  Deferring this optimization until we do some
      benchmarking.
