          Johannes and Pravin Shelar are working on fixing things properly.
      
       2) Do not drop ipv6 ICMP messages without a redirected header option,
          they are legal.  From Duan Jiong.
      
       3) Missing error return propagation in probing of via-ircc driver.
          From Alexey Khoroshilov.

      Fix the issue with improper counting number of flying bio requests for
      BIO_EOPNOTSUPP error detection case.
      
      The sb_nbio must be incremented exactly the same number of times as
      complete() function was called (or will be called) because
      nilfs_segbuf_wait() will call wail_for_completion() for the number of
      times set to sb_nbio:
      
        do {
            wait_for_completion(&segbuf->sb_bio_event);
        } while (--segbuf->sb_nbio > 0);
      
      Two functions complete() and wait_for_completion() must be called the
      same number of times for the same sb_bio_event.  Otherwise,
      wait_for_completion() will hang or leak.

      drivers/platform/olpc/olpc-ec.c: initialise earlier · 93dbc1b3
      Daniel Drake authored
      Being a low-level component, various drivers (e.g.  olpc-battery) assume
      that it is ok to communicate with the OLPC Embedded Controller during
      probe.  Therefore the OLPC EC driver must be initialised before other
      drivers try to use it.  This was the case until it was recently moved
      out of arch/x86 and restructured around commits ac250415 ("Platform:
      OLPC: turn EC driver into a platform_driver") and 85f90cf6 ("x86:
      OLPC: switch over to using new EC driver on x86").
      
      Use arch_initcall so that olpc-ec is readied earlier, matching the
      previous behaviour.
      
      Fixes a regression introduced in Linux-3.6 where various drivers such as
      olpc-battery and olpc-xo1-sci failed to load due to an inability to
      communicate with the EC.  The user-visible effect was a lack of battery
      monitoring, missing ebook/lid switch input devices, etc.

      ipv4: expose IPV4_DEVCONF · 4a5a8aa6
      stephen hemminger authored
      IP sends device configuration (see inet_fill_link_af) as an array
      in the netlink information, but the indices in that array are not
      exposed to userspace through any current santized header file.
      
      It was available back in 2.6.32 (in /usr/include/linux/sysctl.h)
      but was broken by:
        commit 02291680
        Author: Eric W. Biederman <ebiederm@xmission.com>
        Date:   Sun Feb 14 03:25:51 2010 +0000
      
          net ipv4: Decouple ipv4 interface parameters from binary sysctl numbers
      
      Eric was solving the sysctl problem but then the indices were re-exposed
      by a later addition of devconf support for IPV4
      
        commit 9f0f7272

      This reverts commit df54d6fa.
      
      The commit isn't necessarily wrong, but because it recalculates the
      random mmap_base every time, it seems to confuse user memory allocators
      that expect contiguous mmap allocations even when the mmap address isn't
      specified.
      
      In particular, the MATLAB Java runtime seems to be unhappy. See
      
        https://bugzilla.kernel.org/show_bug.cgi?id=60774
      
      So we'll want to apply the random offset only once, and Radu has a patch
      for that.  Revert this older commit in order to apply the other one.

      ARM: tegra: always enable USB VBUS regulators · 30ca2226
      Stephen Warren authored
      This fixes a regression exposed during the merge window by commit
      9f310ded "ARM: tegra: fix VBUS regulator GPIO polarity in DT"; namely that
      USB VBUS doesn't get turned on, so USB devices are not detected. This
      affects the internal USB port on TrimSlice (i.e. the USB->SATA bridge, to
      which the SSD is connected) and the external port(s) on Seaboard/
      Springbank and Whistler.
      
      The Tegra DT as written in v3.11 allows two paths to enable USB VBUS:
      
      1) Via the legacy DT binding for the USB controller; it can directly
         acquire a VBUS GPIO and activate it.
      
      2) Via a regulator for VBUS, which is referenced by the new DT binding
         for the USB controller.
      
      Those two methods both use the same GPIO, and hence whichever of the
      USB controller and regulator gets probed first ends up owning the GPIO.
      In practice, the USB driver only supports path (1) above, since the
      patches to support the new USB binding are not present until v3.12:-(
      
      In practice, the regulator ends up being probed first and owning the
      GPIO. Since nothing enables the regulator (the USB driver code is not
      yet present), the regulator ends up being turned off. This originally
      caused no problem, because the polarity in the regulator definition was
      incorrect, so attempting to turn off the regulator actually turned it
      on, and everything worked:-(
      
      However, when testing the new USB driver code in v3.12, I noticed the
      incorrect polarity and fixed it in commit 9f310ded "ARM: tegra: fix VBUS
      regulator GPIO polarity in DT". In the context of v3.11, this patch then
      caused the USB VBUS to actually turn off, which broke USB ports with VBUS
      control. I got this patch included in v3.11-rc1 since it fixed a bug in
      device tree (incorrect polarity specification), and hence was suitable to
      be included early in the rc series. I evidently did not test the patch at
      all, or correctly, in the context of v3.11, and hence did not notice the
      issue that I have explained above:-(
      
      Fix this by making the USB VBUS regulators always enabled. This way, if
      the regulator owns the GPIO, it will always be turned on, even if there
      is no USB driver code to request the regulator be turned on. Even
      ignoring this bug, this is a reasonable way to configure the HW anyway.
      
      If this patch is applied to v3.11, it will cause a couple pretty trivial
      conflicts in tegra20-{trimslice,seaboard}.dts when creating v3.12, since
      the context right above the added lines changed in patches destined for
      v3.12.

      hso: Fix stack corruption on some architectures · e75dc677
      Daniel Gimpelevich authored
      As Sergei Shtylyov explained in the #mipslinux IRC channel:
      [Mon 2013-08-19 12:28:21 PM PDT] <headless> guys, are you sure it's not "DMA off stack" case?
      [Mon 2013-08-19 12:28:35 PM PDT] <headless> it's a known stack corruptor on non-coherent arches
      [Mon 2013-08-19 12:31:48 PM PDT] <DonkeyHotei> headless: for usb/ehci?
      [Mon 2013-08-19 12:34:11 PM PDT] <DonkeyHotei> headless: explain
      [Mon 2013-08-19 12:35:38 PM PDT] <headless> usb_control_msg() (or other such func) should not use buffer on stack. DMA from/to stack is prohibited
      [Mon 2013-08-19 12:35:58 PM PDT] <headless> and EHCI uses DMA on control xfers (as well as all the others)

      There is no need to get an interface specification if we know it's the
      wrong one.

      Already existing property flags are filled wrong for properties created from
      initial FDT. This could cause problems if this DYNAMIC device-tree functions
      are used later, i.e. properties are attached/detached/replaced. Simply dumping
      flags from the running system show, that some initial static (not allocated via
      kzmalloc()) nodes are marked as dynamic.
      
      I putted some debug extensions to property_proc_show(..) :
      ..
      +       if (OF_IS_DYNAMIC(pp))
      +               pr_err("DEBUG: xxx : OF_IS_DYNAMIC\n");
      +       if (OF_IS_DETACHED(pp))
      +               pr_err("DEBUG: xxx : OF_IS_DETACHED\n");
      
      when you operate on the nodes (e.g.: ~$ cat /proc/device-tree/*some_node*) you
      will see that those flags are filled wrong, basically in most cases it will dump
      a DYNAMIC or DETACHED status, which is in not true.
      (BTW. this OF_IS_DETACHED is a own define for debug purposes which which just
      make a test_bit(OF_DETACHED, &x->_flags)
      
      If nodes are dynamic kernel is allowed to kfree() them. But it will crash
      attempting to do so on the nodes from FDT -- they are not allocated via
      kzmalloc().
