      r8169: enable napi on resume. · cff4c162
      Artem Savkov authored
      NAPI is disabled during suspend and needs to be enabled on resume. Without
      this the driver locks up during resume in rtl_reset_work() trying to disable
      NAPI again.

      bnx2x: correction to firmware interface · f2ed5ee1
      Yuval Mintz authored
      Commit 621b4d66 updated the bnx2x driver to a new FW version, but lacked
      a commit to a header file with changes to the firmware's interface.
      The missing interface change causes iscsi and fcoe to misbehave with the
      updated firmware.

      phy:icplus:fix Auto Power Saving in ip101a_config_init. · b3300146
      Srinivas Kandagatla authored
      This patch fixes Auto Power Saving configuration in ip101a_config_init
      which was broken as there is no phy register write followed after
      setting IP101A_APS_ON flag.
      
      This patch also fixes the return value of ip101a_config_init.
      
      Without this patch ip101a_config_init returns 2 which is not an error
      accroding to IS_ERR and the mac driver will continue accessing 2 as
      valid pointer to phy_dev resulting in memory fault.

      ixgbe: driver fix for link flap · aacc1bea
      Multanen, Eric W authored
      Fix up code so that changes in DCB settings
      are detected only when ixgbe_dcbnl_set_all is called.
      Previously, a series of 'change' commands followed by
      a call to ixgbe_dcbnl_set_all() would always be handled
      as a HW change - even if the net change was zero.
      This patch checks for this case of no actual change and
      skips going through the HW set process.
      
      Without this fix, the link could reset and result in
      a link flap.
      
      The core change in this patch is to check for changes
      in the ixgbe_copy_dcb_cfg() routine - and return
      a bitmask of detected changes.  The other
      places where changes were detected previously can be removed.

      bpf jit: Let the x86 jit handle negative offsets · a998d434
      Jan Seiffert authored
      Now the helper function from filter.c for negative offsets is exported,
      it can be used it in the jit to handle negative offsets.
      
      First modify the asm load helper functions to handle:
      - know positive offsets
      - know negative offsets
      - any offset
      
      then the compiler can be modified to explicitly use these helper
      when appropriate.
      
      This fixes the case of a negative X register and allows to lift
      the restriction that bpf programs with negative offsets can't
      be jited.

      tcp: allow splice() to build full TSO packets · 2f533844
      Eric Dumazet authored
      vmsplice()/splice(pipe, socket) call do_tcp_sendpages() one page at a
      time, adding at most 4096 bytes to an skb. (assuming PAGE_SIZE=4096)
      
      The call to tcp_push() at the end of do_tcp_sendpages() forces an
      immediate xmit when pipe is not already filled, and tso_fragment() try
      to split these skb to MSS multiples.
      
      4096 bytes are usually split in a skb with 2 MSS, and a remaining
      sub-mss skb (assuming MTU=1500)
      
      This makes slow start suboptimal because many small frames are sent to
      qdisc/driver layers instead of big ones (constrained by cwnd and packets
      in flight of course)
      
      In fact, applications using sendmsg() (adding an additional memory copy)
      instead of vmsplice()/splice()/sendfile() are a bit faster because of
      this anomaly, especially if serving small files in environments with
      large initial [c]wnd.
      
      Call tcp_push() only if MSG_MORE is not set in the flags parameter.
      
      This bit is automatically provided by splice() internals but for the
      last page, or on all pages if user specified SPLICE_F_MORE splice()
      flag.
      
      In some workloads, this can reduce number of sent logical packets by an
      order of magnitude, making zero-copy TCP actually faster than
      one-copy :)

      ppp: Don't stop and restart queue on every TX packet · e675f0cc
      David Woodhouse authored
      For every transmitted packet, ppp_start_xmit() will stop the netdev
      queue and then, if appropriate, restart it. This causes the TX softirq
      to run, entirely gratuitously.
      
      This is "only" a waste of CPU time in the normal case, but it's actively
      harmful when the PPP device is a TEQL slave — the wakeup will cause the
      offending device to receive the next TX packet from the TEQL queue, when
      it *should* have gone to the next slave in the list. We end up seeing
      large bursts of packets on just *one* slave device, rather than using
      the full available bandwidth over all slaves.
      
      This patch fixes the problem by *not* unconditionally stopping the queue
      in ppp_start_xmit(). It adds a return value from ppp_xmit_process()
      which indicates whether the queue should be stopped or not.
      
      It *doesn't* remove the call to netif_wake_queue() from
      ppp_xmit_process(), because other code paths (especially from
      ppp_output_wakeup()) need it there and it's messy to push it out to the
      other callers to do it based on the return value. So we leave it in
      place — it's a no-op in the case where the queue wasn't stopped, so it's
      harmless in the TX path.

      net: fix /proc/net/dev regression · 2def16ae
      Eric Dumazet authored
      Commit f04565dd (dev: use name hash for dev_seq_ops) added a second
      regression, as some devices are missing from /proc/net/dev if many
      devices are defined.
      
      When seq_file buffer is filled, the last ->next/show() method is
      canceled (pos value is reverted to value prior ->next() call)
      
      Problem is after above commit, we dont restart the lookup at right
      position in ->start() method.
      
      Fix this by removing the internal 'pos' pointer added in commit, since
      we need to use the 'loff_t *pos' provided by seq_file layer.
      
      This also reverts commit 5cac98dd (net: Fix corruption
      in /proc/*/net/dev_mcast), since its not needed anymore.

       "This pull just contains a forward of the Intel fixes from Daniel.
      
        The only annoyance is the RC6 enable, which really should have made
        -next, but since Ubuntu are shipping it I reckon its getting a good
        testing now by the time 3.4 comes out.
      
        The pull from Daniel contains his pull message to me:
      
          "A few patches for 3.4, major part is 3 regression fixes:
           - ppgtt broke hibernate on snb/ivb.  Somehow our QA claims that it

           - ppgtt flails in combination with dmar.  I kinda expected this one :(

           Wrt regressions I've just got a report that gmbus (newly enabled
           again in 3.4) is a bit noisy.  I'm looking into this atm.

           wanted to include these in the main 3.4 pull but screwed it up.
           Please hit me.  Imo these kind of patches really should go in

      Let's see if the "enable RC6 on sandybridge" finally works and sticks.
      I've been enabling it by hand (i915.i915_enable_rc6=1) for several
      months on my Macbook Air, and it definitely makes a difference (and has
      worked for me).  But every time we enabled it before it showed some odd
      hw buglet for *somebody*.
      
      This time it's all good, I'm sure.

      mplayer -vo fbdev tries to create a screen that is twice as tall as the
      allocated framebuffer for "doublebuffering". By default, and all in-tree
      users, only sufficient memory is allocated and mapped to satisfy the
      smallest framebuffer and the virtual size is no larger than the actual.
      For these users, we should therefore reject any userspace request to
      create a screen that requires a buffer larger than the framebuffer
      originally allocated.

      drm/i915: Add lock on drm_helper_resume_force_mode · 927a2f11
      Sean Paul authored
      i915_drm_thaw was not locking the mode_config lock when calling
      drm_helper_resume_force_mode. When there were multiple wake sources,
      this caused FDI training failure on SNB which in turn corrupted the
      display.

      Pull dma-buf prime support from Dave Airlie:
       "This isn't a majorly urgent thing to have, but we'd like to set the
        stage for working on dma-buf support in the drm drivers for the next
        merge window, so I'd like to push in the initial submission now so
        people have something that we can build on top of.  The code just
        introduces the user interface and internal helper functions for
        drivers to use.
      
        We have driver support under development for i915, nouveau, udl on x86
        and exynos, omapdrm on arm, which we would be aiming for the next
        merge window."
      
      In the -rc1 announcement I asked for people who would use this to
      comment on it, and got severa "Yes please" from people for this and for
      HSI (that I merged earlier).

      There were no build regressions since all consumers were already getting

      Some minor whitespace fixups were done on the block of code that created

      Commit bf4289cb ("ATMEL: fix nand ecc support") indicated that it

      re-include protectors with:
      
          #ifndef __ATMEL_NAND_H__
      
      However, the file that was added was simply called atmel.h
      and this caused avr32 defconfig to fail with:

      It seems the scope of the file contents will expand beyond
      just nand, so ignore the original intention, and fix up the
      users who reference the bad name with the _nand suffix.

      Pull cpumask cleanups from Rusty Russell:
       "(Somehow forgot to send this out; it's been sitting in linux-next, and
        if you don't want it, it can sit there another cycle)"
      
      I'm a sucker for things that actually delete lines of code.
      
      Fix up trivial conflict in arch/arm/kernel/kprobes.c, where Rusty fixed
      a user of &cpu_online_map to be cpu_online_mask, but that code got
      deleted by commit b21d55e9 ("ARM: 7332/1: extract out code patch
      function from kprobes").
