Pull ACPI video support fixes from Rafael Wysocki:
 "I'm sending a separate pull request for this as it may be somewhat
  controversial.  The breakage addressed here is not really new and the
  fixes may not satisfy all users of the affected systems, but we've had
  so much back and forth dance in this area over the last several weeks
  that I think it's time to actually make some progress.

  The source of the problem is that about a year ago we started to tell
  BIOSes that we're compatible with Windows 8, which we really need to
  do, because some systems shipping with Windows 8 are tested with it
  and nothing else, so if we tell their BIOSes that we aren't compatible
  with Windows 8, we expose our users to untested BIOS/AML code paths.

  However, as it turns out, some Windows 8-specific AML code paths are
  not tested either, because Windows 8 actually doesn't use the ACPI
  methods containing them, so if we declare Windows 8 compatibility and
  attempt to use those ACPI methods, things break.  That occurs mostly
  in the backlight support area where in particular the _BCM and _BQC
  methods are plain unusable on some systems if the OS declares Windows
  8 compatibility.

  [ The additional twist is that they actually become usable if the OS
    says it is not compatible with Windows 8, but that may cause
    problems to show up elsewhere ]

  Investigation carried out by Matthew Garrett indicates that what
  Windows 8 does about backlight is to leave backlight control up to
  individual graphics drivers.  At least there's evidence that it does
  that if the Intel graphics driver is used, so we've decided to follow
  Windows 8 in that respect and allow i915 to control backlight (Daniel
  likes that part).

  The first commit from Aaron Lu makes ACPICA export the variable from
  which we can infer whether or not the BIOS believes that we are
  compatible with Windows 8.

  The second commit from Matthew Garrett prepares the ACPI video driver
  by making it initialize the ACPI backlight even if it is not going to
  be used afterward (that is needed for backlight control to work on
  Thinkpads).

  The third commit implements the actual workaround making i915 take
  over backlight control if the firmware thinks it's dealing with
  Windows 8 and is based on the work of multiple developers, including
  Matthew Garrett, Chun-Yi Lee, Seth Forshee, and Aaron Lu.

  The final commit from Aaron Lu makes us follow Windows 8 by informing
  the firmware through the _DOS method that it should not carry out
  automatic brightness changes, so that brightness can be controlled by
  GUI.

  Hopefully, this approach will allow us to avoid using blacklists of
  systems that should not declare Windows 8 compatibility just to avoid
  backlight control problems in the future.

   - Change from Aaron Lu makes ACPICA export a variable which can be
     used by driver code to determine whether or not the BIOS believes
     that we are compatible with Windows 8.

   - Change from Matthew Garrett makes the ACPI video driver initialize
     the ACPI backlight even if it is not going to be used afterward
     (that is needed for backlight control to work on Thinkpads).

   - Fix from Rafael J Wysocki implements Windows 8 backlight support
     workaround making i915 take over bakclight control if the firmware
     thinks it's dealing with Windows 8.  Based on the work of multiple
     developers including Matthew Garrett, Chun-Yi Lee, Seth Forshee,
     and Aaron Lu.

   - Fix from Aaron Lu makes the kernel follow Windows 8 by informing
     the firmware through the _DOS method that it should not carry out
     automatic brightness changes, so that brightness can be controlled
     by GUI"

Pull staging tree fixes from Greg KH:
 "Here are a few iio driver fixes for 3.11-rc2.  They are still spread
  across drivers/iio and drivers/staging/iio so they are coming in
  through this tree.

  I've also removed the drivers/staging/csr/ driver as the developers
  who originally sent it to me have moved on to other companies, and CSR
  still will not send us the specs for the device, making the driver
  pretty much obsolete and impossible to fix up.  Deleting it now
  prevents people from sending in lots of tiny codingsyle fixes that
  will never go anywhere.

  It also helps to offset the large lustre filesystem merge that
  happened in 3.11-rc1 in the overall 3.11.0 diffstat.  :)"

Pull power management and ACPI fixes from Rafael Wysocki:
 "These are fixes collected over the last week, most importnatly two
  cpufreq reverts fixing regressions introduced in 3.10, an autoseelp
  fix preventing systems using it from crashing during shutdown and two
  ACPI scan fixes related to hotplug.

  Specifics:

   - Two cpufreq commits from the 3.10 cycle introduced regressions.
     The first of them was buggy (it did way much more than it needed to
     do) and the second one attempted to fix an issue introduced by the
     first one.  Fixes from Srivatsa S Bhat revert both.

   - If autosleep triggers during system shutdown and the shutdown
     callbacks of some device drivers have been called already, it may
     crash the system.  Fix from Liu Shuo prevents that from happening
     by making try_to_suspend() check system_state.

   - The ACPI memory hotplug driver doesn't clear its driver_data on
     errors which may cause a NULL poiter dereference to happen later.
     Fix from Toshi Kani.

   - The ACPI namespace scanning code should not try to attach scan
     handlers to device objects that have them already, which may
     confuse things quite a bit, and it should rescan the whole
     namespace branch starting at the given node after receiving a bus
     check notify event even if the device at that particular node has
     been discovered already.  Fixes from Rafael J Wysocki.

   - New ACPI video blacklist entry for a system whose initial backlight
     setting from the BIOS doesn't make sense.  From Lan Tianyu.

   - Garbage string output avoindance for ACPI PNP from Liu Shuo.

   - Two Kconfig fixes for issues introduced recently in the s3c24xx
     cpufreq driver (when moving the driver to drivers/cpufreq) from
     Paul Bolle.

Pull networking fixes from David Miller:
 "A couple interesting SKB fragment handling fixes, plus the usual small
  bits here and there:

   1) Fix 64-bit divide build failure on 32-bit platforms in mlx5, from
      Tim Gardner.

   2) Get rid of a stupid reimplementation on "%*phC" in our sysfs MAC
      address printing helper.

   3) Fix NETIF_F_SG capability advertisement in hyperv driver, if the
      device can't do checksumming offloads then it shouldn't say it can
      do SG either.  From Haiyang Zhang.

   4) bgmac needs to depend on PHYLIB, from Hauke Mehrtens.

   5) Don't leak DMA mappings on mapping failures, from Neil Horman.

   6) We need to reset the transport header of SKBs in ipv4 before we
      attempt to perform early socket demux, just like ipv6 does.  From
      Eric Dumazet.

   7) Add missing locking on vxlan device removal, from Stephen
      Hemminger.

   8) xen-netfront has to make two passes over an SKB to prepare it for
      transfer.  One pass calculates the number of slots needed, the
      second massages the SKB and fills the slots.  Unfortunately, the
      first pass doesn't calculate the number of slots properly so we
      can end up trying to build a MAX_SKB_FRAGS + 1 SKB which doesn't
      work out so well.  Fix from Jan Beulich with help and discussion
      with several others.

   9) Fix a similar problem in tun and macvtap, which have to split up
      scatter-gather elements at PAGE_SIZE boundaries.  Don't do
      zerocopy if it would result in a > MAX_SKB_FRAGS skb.  Fixes from
      Jason Wang.

  10) On receive, once we've decoded the VLAN state completely, clear
      skb->vlan_tci.  Otherwise demuxed tunnels underneath can trigger
      the VLAN code again, corrupting the packet.  Fix from Eric
      Dumazet"

In commit 48cc32d38a52d0b68f91a171a8d00531edc6a46e
("vlan: don't deliver frames for unknown vlans to protocols")
Florian made sure we set pkt_type to PACKET_OTHERHOST
if the vlan id is set and we could find a vlan device for this
particular id.

But we also have a problem if prio bits are set.

Steinar reported an issue on a router receiving IPv6 frames with a
vlan tag of 4000 (id 0, prio 2), and tunneled into a sit device,
because skb->vlan_tci is set.

Forwarded frame is completely corrupted : We can see (8100:4000)
being inserted in the middle of IPv6 source address :

16:48:00.780413 IP6 2001:16d8:8100:4000:ee1c:0:9d9:bc87 >
9f94:4d95:2001:67c:29f4::: ICMP6, unknown icmp6 type (0), length 64

       0x0030:  2425 2627 2829 2a2b 2c2d 2e2f 3031 3233

It seems we are not really ready to properly cope with this right now.

We can probably do better in future kernels :
vlan_get_ingress_priority() should be a netdev property instead of
a per vlan_dev one.

For stable kernels, lets clear vlan_tci to fix the bugs.

Pull driver core patches from Greg KH:
 "Here are some driver core patches for 3.11-rc2.  They aren't really
  bugfixes, but a bunch of new helper macros for drivers to properly
  create attribute groups, which drivers and subsystems need to fix up a
  ton of race issues with incorrectly creating sysfs files (binary and
  normal) after userspace has been told that the device is present.

  Also here is the ability to create binary files as attribute groups,
  to solve that race condition, which was impossible to do before this,
  so that's my fault the drivers were broken.

  The majority of the .c changes is indenting and moving code around a
  bit.  It affects no existing code, but allows the large backlog of 70+
  patches that I already have created to start flowing into the
  different subtrees, instead of having to live in my driver-core tree,
  causing merge nightmares in linux-next for the next few months.

  These were finalized too late for the -rc1 merge window, which is why
  they were didn't make that pull request, testing and review from
  others didn't happen until a few weeks ago, and then there's the whole
  distraction of the past few days, which prevented these from getting
  to you sooner, sorry about that.

  Oh, and there's a bugfix for the documentation build warning in here
  as well.  All of these have been in linux-next this week, with no
  reported problems"

Pull phase two of __cpuinit removal from Paul Gortmaker:
 "With the __cpuinit infrastructure removed earlier, this group of
  commits only removes the function/data tagging that was done with the
  various (now no-op) __cpuinit related prefixes.

  Now that the dust has settled with yesterday's v3.11-rc1, there
  hopefully shouldn't be any new users leaking back in tree, but I think
  we can leave the harmless no-op stubs there for a release as a
  courtesy to those who still have out of tree stuff and weren't paying
  attention.

  Although the commits are against the recent tag to allow for minor
  context refreshes for things like yesterday's v3.11-rc1~ slab content,
  the patches have been largely unchanged for weeks, aside from such
  trivial updates.

  For detail junkies, the largely boring and mostly irrelevant history
  of the patches can be viewed at:

    http://git.kernel.org/cgit/linux/kernel/git/paulg/cpuinit-delete.git

  If nothing else, I guess it does at least demonstrate the level of
  involvement required to shepherd such a treewide change to completion.

  end of the daily linux-next branches for the past several weeks"
