Pull networking fixes from David Miller:

 1) Always increment IPV4 ID field in encapsulated GSO packets, even
    when DF is set.  Regression fix from Pravin B Shelar.

 2) Fix per-net subsystem initialization in netfilter conntrack,
    otherwise we may access dynamically allocated memory before it is
    actually allocated.  From Gao Feng.

 3) Fix DMA buffer lengths in iwl3945 driver, from Stanislaw Gruszka.

 4) Fix race between submission of sync vs async commands in mwifiex
    driver, from Amitkumar Karwar.

 5) Add missing cancel of command timer in mwifiex driver, from Bing
    Zhao.

 6) Missing SKB free in rtlwifi USB driver, from Jussi Kivilinna.

 7) Thermal layer tries to use a genetlink multicast string that is
    longer than the 16 character limit.  Fix it and add a BUG check to
    prevent this kind of thing from happening in the future.

 From Masatake YAMATO.

 8) Fix many bugs in the handling of the teardown of L2TP connections,
    UDP encapsulation instances, and sockets.  From Tom Parkin.

13) Some FOO_DIAG_MAX constants were defined off by one, fix from Andrey
    Vagin.

14) TCP segmentation deferral is unintentionally done too strongly,
    breaking ACK clocking.  Fix from Eric Dumazet.

15) net_enable_timestamp() can legitimately be invoked from software
    interrupts, and in a way that is safe, so remove the WARN_ON().
    Also from Eric Dumazet.

16) Fix use after free in VLANs, from Cong Wang.

17) Fix TCP slow start retransmit storms after SACK reneging, from
    Yuchung Cheng.

18) Unix socket release should mark a socket dead before NULL'ing out
    sock->sk, otherwise we can race.  Fix from Paul Moore.

19) IPV6 addrconf code can try to free static memory, from Hong Zhiguo.

20) Fix register mis-programming, NULL pointer derefs, and wrong PHC
    clock frequency in IGB driver.  From Lior LevyAlex Williamson, Jiri
    Benc, and Jeff Kirsher.

21) skb->ip_summed logic in pch_gbe driver is reversed, breaking packet
    forwarding.  Fix from Veaceslav Falico.

Pablo Neira Ayuso says:

====================
The following patchset contains 7 Netfilter/IPVS fixes for 3.9-rc, they are:

* Restrict IPv6 stateless NPT targets to the mangle table. Many users are
  complaining that this target does not work in the nat table, which is the
  wrong table for it, from Florian Westphal.

* Fix possible use before initialization in the netns init path of several
  conntrack protocol trackers (introduced recently while improving conntrack
  netns support), from Gao Feng.

* Fix incorrect initialization of copy_range in nfnetlink_queue, spotted
  by Eric Dumazet during the NFWS2013, patch from myself.

* Fix wrong calculation of next SCTP chunk in IPVS, from Julian Anastasov.

* Remove rcu_read_lock section in IPVS while calling ipv4_update_pmtu
  not required anymore after change introduced in 3.7, again from Julian.

* Fix SYN looping in IPVS state sync if the backup is used a real server
  in DR/TUN modes, this required a new /proc entry to disable the director
  function when acting as backup, also from Julian.

* Remove leftover IP_NF_QUEUE Kconfig after ip_queue removal, noted by
  Paul Bolle.

0c12582fbc ipvs: add backup_only flag to avoid loops
Dmitry Akindinov is reporting for a problem where SYNs are looping
between the master and backup server when the backup server is used as
real server in DR mode and has IPVS rules to function as director.

Even when the backup function is enabled we continue to forward
traffic and schedule new connections when the current master is using
the backup server as real server. While this is not a problem for NAT,
for DR and TUN method the backup server can not determine if a request
comes from client or from director.

To avoid such loops add new sysctl flag backup_only. It can be needed
for DR/TUN setups that do not need backup and director function at the
same time. When the backup function is enabled we stop any forwarding
and pass the traffic to the local stack (real server mode). The flag
disables the director function when the backup function is enabled.

For setups that enable backup function for some virtual services and
director function for other virtual services there should be another
more complex solution to support DR/TUN mode, may be to assign
per-virtual service syncid value, so that we can differentiate the
requests.

The ab8500 device is a child of the prcmu device, which is a memory mapped
bus device, whose children are addressable using physical memory addresses,
not using mailboxes, so a mailbox number in the ab8500 node cannot be
parsed by DT. Nothing uses this number, since it was only introduced
as part of the failed attempt to clean up prcmu mailbox handling, and
we can simply remove it.

External SoC interrupts (from HWSTATEXT and friends) are vectored onto
the TR2 core trigger for the current thread. This is demultiplexed in
irq-metag-ext.c to individual Linux IRQs for each external SoC interrupt.
The external irqchip has devicetree bindings for configuring the number
of irq banks and the type of masking available.

20e6926dcb x86, ACPI, mm: Revert movablemem_map support

Don Morris reproduced on a HP z620 workstation, and bisected it to
commit e8d1955258 ("acpi, memory-hotplug: parse SRAT before memblock
is ready")

It turns out movable_map has some problems, and it breaks several things

1. numa_init is called several times, NOT just for srat. so those
	nodes_clear(numa_nodes_parsed)
	memset(&numa_meminfo, 0, sizeof(numa_meminfo))
   can not be just removed.  Need to consider sequence is: numaq, srat, amd, dummy.
   and make fall back path working.

2. simply split acpi_numa_init to early_parse_srat.
   a. that early_parse_srat is NOT called for ia64, so you break ia64.
   b.  for (i = 0; i < MAX_LOCAL_APIC; i++)
	     set_apicid_to_node(i, NUMA_NO_NODE)
     still left in numa_init. So it will just clear result from early_parse_srat.
     it should be moved before that....
   c.  it breaks ACPI_TABLE_OVERIDE...as the acpi table scan is moved
       early before override from INITRD is settled.

3. that patch TITLE is total misleading, there is NO x86 in the title,
   but it changes critical x86 code. It caused x86 guys did not
   pay attention to find the problem early. Those patches really should
   be routed via tip/x86/mm.

4. after that commit, following range can not use movable ram:
  a. real_mode code.... well..funny, legacy Node0 [0,1M) could be hot-removed?
  b. initrd... it will be freed after booting, so it could be on movable...
  c. crashkernel for kdump...: looks like we can not put kdump kernel above 4G
	anymore.
  d. init_mem_mapping: can not put page table high anymore.
  e. initmem_init: vmemmap can not be high local node anymore. That is
     not good.

If node is hotplugable, the mem related range like page table and
vmemmap could be on the that node without problem and should be on that
node.

We have workaround patch that could fix some problems, but some can not
be fixed.

So just remove that offending commit and related ones including:

 f7210e6c4a ("mm/memblock.c: use CONFIG_HAVE_MEMBLOCK_NODE_MAP to
    protect movablecore_map in memblock_overlaps_region().")

 01a178a94e ("acpi, memory-hotplug: support getting hotplug info from
    SRAT")

 27168d38fa ("acpi, memory-hotplug: extend movablemem_map ranges to
    the end of node")

 e8d1955258 ("acpi, memory-hotplug: parse SRAT before memblock is
    ready")

 fb06bc8e5f ("page_alloc: bootmem limit with movablecore_map")

 42f47e27e7 ("page_alloc: make movablemem_map have higher priority")

 6981ec3114 ("page_alloc: introduce zone_movable_limit[] to keep
    movable limit for nodes")

 34b71f1e04 ("page_alloc: add movable_memmap kernel parameter")

 4d59a75125 ("x86: get pg_data_t's memory from other node")

Later we should have patches that will make sure kernel put page table
and vmemmap on local node ram instead of push them down to node0.  Also
need to find way to put other kernel used ram to local node ram.

Merge tag 'arc-v3.9-rc1-late' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc

Pull new ARC architecture from Vineet Gupta:
 "Initial ARC Linux port with some fixes on top for 3.9-rc1:

  I would like to introduce the Linux port to ARC Processors (from
  Synopsys) for 3.9-rc1.  The patch-set has been discussed on the public
  lists since Nov and has received a fair bit of review, specially from
  Arnd, tglx, Al and other subsystem maintainers for DeviceTree, kgdb...

  The arch bits are in arch/arc, some asm-generic changes (acked by
  Arnd), a minor change to PARISC (acked by Helge).

  The series is a touch bigger for a new port for 2 main reasons:

   1. It enables a basic kernel in first sub-series and adds
      ptrace/kgdb/.. later

   2. Some of the fallout of review (DeviceTree support, multi-platform-
      image support) were added on top of orig series, primarily to
      record the revision history.

  This updated pull request additionally contains

   - fixes due to our GNU tools catching up with the new syscall/ptrace
     ABI

   - some (minor) cross-arch Kconfig updates."

 o The Qualcomm Atheros platform is extended by support for the new

   ready for OF support.

 o Lantiq and BCM47XX platform have a few improvements and bug fixes.

 o MIPS has sent a few patches that get the kernel ready for the
   upcoming microMIPS support.

 o The rest of the series is made up of small bug fixes and cleanups
   that relate to various parts of the MIPS code.  The biggy in there is
   a whitespace cleanup.  After I was sent another set of whitespace
   cleanup patches I decided it was the time to clean the whitespace
   "issues" for once and and that touches many files below arch/mips/.

1a32c58bb9 arm-soc: mvebu platform changes
This series contains changes for the Marvell EBU platforms (mvebu,
 orion, kirkwood, dove) that were not part of the first set of pull
 requests because of dependencies on the MMC tree, and being submitted
 a little late.
 
 Notable changes are:
 
 * More devices get moved out of board files into device tree
   descriptions. The remaining devices listed in there have patches
   that will get sent for 3.10, after which we can remove a lot of the
   board files entirely. We are doing the pinctrl and mmc drivers here,
   ethernet and PCI still remain.
 
 * SMP support for mvebu is improved with support for the
   local interrupt controller.
 
 * The Guruplug board file gets replaced with a DT description.
 
 Unfortunately, the dependency on the MMC tree turned out to be a much
 larger problem than expected, when the MMC maintainer rebased the patches
 in his tree that all of the patches in this branch are based on, which
 caused merge conflicts between the new and old versions of those patches.
 
 To work around the merge conflicts, this branch rebases all patches
 on top of the respective MMC patches that did get merged into 3.9.
 The patches are all identical to the versions that were part of
 linux-next, but have a new commit date.
 
 Merge conflicts:
 
 * in board-nsa310.c, the gpio.h inclusion was removed prematurely and
   put back as a bug fix earlier. With this series it is really not needed
   any more.
 
 * The patch to add rtc support was already applied by Andrew Morton,
   and conflicts with a second copy that was in this series, which adds

Merge tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC mvebu platform changes from Olof Johansson:
 "This series contains changes for the Marvell EBU platforms (mvebu,
  orion, kirkwood, dove) that were not part of the first set of pull
  requests because of dependencies on the MMC tree, and being submitted
  a little late.

  Notable changes are:

   - More devices get moved out of board files into device tree
     descriptions.  The remaining devices listed in there have patches
     that will get sent for 3.10, after which we can remove a lot of the
     board files entirely.  We are doing the pinctrl and mmc drivers
     here, ethernet and PCI still remain.

   - SMP support for mvebu is improved with support for the local
     interrupt controller.

   - The Guruplug board file gets replaced with a DT description.

  Unfortunately, the dependency on the MMC tree turned out to be a much
  larger problem than expected, when the MMC maintainer rebased the
  patches in his tree that all of the patches in this branch are based
  on, which caused merge conflicts between the new and old versions of
  those patches.

  To work around the merge conflicts, this branch rebases all patches on
  top of the respective MMC patches that did get merged into 3.9.  The
  patches are all identical to the versions that were part of
  linux-next, but have a new commit date."

f8f466c817 arm-soc: i.MX DT changes
This branch contains of devicetree changes for the Freescale i.MX platform.
 
 The base patch of the branch changes the format of the dts files to a
 slightly different format that makes it easier to do derivative board
 definitions, but it also introduces a lot of churn in the process since
 every line of the file is touched.
 
 On top of that are a handful of the regular changes; enabling more boards
 as DT-based instead of legacy board files (mx25pdk), enabling another
 driver for devicetree and thus adding bindings (onewire), etc.
 
 I'm not happy about the churn, and will likely not take it for other platforms
 in the future.

Pull block IO core bits from Jens Axboe:
 "Below are the core block IO bits for 3.9.  It was delayed a few days
  since my workstation kept crashing every 2-8h after pulling it into
  current -git, but turns out it is a bug in the new pstate code (divide
  by zero, will report separately).  In any case, it contains:

   - The big cfq/blkcg update from Tejun and and Vivek.

   - Additional block and writeback tracepoints from Tejun.

   - Improvement of the should sort (based on queues) logic in the plug
     flushing.

   - _io() variants of the wait_for_completion() interface, using
     io_schedule() instead of schedule() to contribute to io wait
     properly.

   - Various little fixes.

  You'll get two trivial merge conflicts, which should be easy enough to
  fix up"

b67bfe0d42: "hlist: drop the node parameter from iterators").
