Pull networking update from David Miller:

 1) Checkpoint/restarted TCP sockets now can properly propagate the TCP
    timestamp offset.  From Andrey Vagin.

 2) VMWARE VM VSOCK layer, from Andy King.

 3) Much improved support for virtual functions and SR-IOV in bnx2x,
    from Ariel ELior.

 4) All protocols on ipv4 and ipv6 are now network namespace aware, and
    all the compatability checks for initial-namespace-only protocols is
    removed.  Thanks to Tom Parkin for helping deal with the last major
    holdout, L2TP.

 5) IPV6 support in netpoll and network namespace support in pktgen,
    from Cong Wang.

 6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration
    Protocol (MVRP) support, from David Ward.

    checks to 6to4 and 6rd.  From Hannes Frederic Sowa.

11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern
    times, rearrange inet frag datastructures for better cacheline
    locality, and move more operations outside of locking.  From Jesper
    Dangaard Brouer.

12) Instead of strict master <--> slave relationships, allow arbitrary

When we set the sun4u version of the PTE execute bit, it's:

	or	REG, _PAGE_EXEC_4U, REG

_PAGE_EXEC_4U is 0x1000, unfortunately the immedate field of the
'or' instruction is a signed 13-bit value.  So the above actually
assembles into:

	or	REG, -4096, REG

completely corrupting the final PTE value.

Set it with a:

	sethi	%hi(_PAGE_EXEC_4U), TMP
	or	REG, TMP, REG

sequence instead.

This fixes "git gc" crashes on sun4u machines.

Because we do not have any locks for dst_entry, we cannot change
essential structure in the entry; e.g., we cannot change reference
to other entity.

To fix this issue, split 'from' and 'expires' field in dst_entry
out of union.  Once it is 'from' is assigned in the constructor,
keep the reference until the very last stage of the life time of
the object.

Of course, it is unsafe to change 'from', so make rt6_set_from simple
just for fresh entries.

Fix up fairly straightforward conflicts in the ab8500 driver.  But since
it seems to be ARM-specific, I can't even compile-test the result..

If our first THP installation for an MM is via the set_pmd_at() done
during khugepaged's collapsing we'll end up in tsb_grow() trying to do
a GFP_KERNEL allocation with several locks held.

Simply using GFP_ATOMIC in this situation is not the best option
because we really can't have this fail, so we'd really like to keep
this an order 0 GFP_KERNEL allocation if possible.

Also, doing the TSB allocation from khugepaged is a really bad idea
because we'll allocate it potentially from the wrong NUMA node in that
context.

So what we do is defer the hugepage TSB allocation until the first TLB
miss we take on a hugepage.  This is slightly tricky because we have
to handle two unusual cases:

1) Taking the first hugepage TLB miss in the window trap handler.
   We'll call the winfix_trampoline when that is detected.

2) An initial TSB allocation via TLB miss races with a hugetlb
   fault on another cpu running the same MM.  We handle this by
   unconditionally loading the TSB we see into the current cpu
   even if it's non-NULL at hugetlb_setup time.

Accomodate the possibility that the TSB might be NULL at
the point that update_mmu_cache() is invoked.  This is
necessary because we will sometimes need to defer the TSB
allocation to the first fault that happens in the 'mm'.

Seperate out the hugepage PTE test into a seperate function

Pull pinctrl changes from Linus Walleij:
 "These are the main pinctrl changes for the v3.9 merge window.  The
  most interesting change by far is how the device core grabs pinctrl
  default handles avoiding the need to stick boilerplate into driver
  consumers.

   - Grabbing of default pinctrl handles from the device core.  These
     are the hunks hitting drivers/base.  All is ACKed by Greg, after a
     long discussion about different alternatives.

   - Some stuff also touches the MFD and ARM SoC trees, this has been
     coordinated and ACKed.

   - New drivers for:
     - The Tegra 114 sub-SoC
     - Allwinner sunxi
     - New ABx500 driver and sub-SoC drivers for AB8500, AB8505, AB9540
       and AB8540.

   - Make it possible for hogged pins to enter a sleep mode, and make it
     possible for drivers to control that mode.

Pull cpuset changes from Tejun Heo:

 - Synchornization has seen a lot of changes with focus on decoupling
   cpuset synchronization from cgroup internal locking.

   After this change, there only remain a couple of mostly trivial
   dependencies on cgroup_lock outside cgroup core proper.  cgroup_lock
   is scheduled to be unexported in this devel cycle.

   This will finally remove the fragile locking order around cgroup
   (cgroup locking wants to / should be one of the outermost but yet has
   been acquired from deep inside individual controllers).

 - At this point, Li is most knowlegeable with cpuset and taking over
   the maintainership of cpuset.

Prepare first set of updates for 3.9 merge window.

Pull workqueue changes from Tejun Heo:
 "A lot of reorganization is going on mostly to prepare for worker pools
  with custom attributes so that workqueue can replace custom pool
  implementations in places including writeback and btrfs and make CPU
  assignment in crypto more flexible.

  workqueue evolved from purely per-cpu design and implementation, so
  there are a lot of assumptions regarding being bound to CPUs and even
  unbound workqueues are implemented as an extension of the model -
  workqueues running on the special unbound CPU.  Bulk of changes this
  round are about promoting worker_pools as the top level abstraction
  replacing global_cwq (global cpu workqueue).  At this point, I'm
  fairly confident about getting custom worker pools working pretty soon
  and ready for the next merge window.

  Lai's patches are replacing the convoluted mb() dancing workqueue has
  been doing with much simpler mechanism which only depends on
  assignment atomicity of long.  For details, please read the commit
  message of 0b3dae68 ("workqueue: simplify is-work-item-queued-here
  test").  While the change ends up adding one pointer to struct
  delayed_work, the inflation in percentage is less than five percent
  and it decouples delayed_work logic a lot more cleaner from usual work
  handling, removes the unusual memory barrier dancing, and allows for
  further simplification, so I think the trade-off is acceptable.

  There will be two more workqueue related pull requests and there are
  some shared commits among them.  I'll write further pull requests
  assuming this pull request is pulled first."

Pull workqueue [delayed_]work_pending() cleanups from Tejun Heo:
 "This is part of on-going cleanups to remove / minimize usages of
  workqueue interfaces which are deprecated and/or misleading.

  This round drops a number of usages of [delayed_]work_pending(), which
  are dangerous as they lack any form of synchronization and thus often
  lead to buggy / unnecessary code.  There are a couple legitimate use
  cases in kernel.  Hopefully, they can be converted and
  [delayed_]work_pending() can be removed completely.  Even if not,
  removing most of misuses should make it more difficult to find
  examples of misuses and thus slow down growth of them.

  These changes are independent from other workqueue changes."

John W. Linville says:

====================
One last batch of stragglers intended for 3.9...

For the iwlwifi pull, Johannes says:

"I hadn't expected to ask you to pull iwlwifi-next again, but I have a
number of fixes most of which I'd also send in after rc1, so here it is.

The first commit is a merge error between mac80211-next and
iwlwifi-next; in addition I have fixes for P2P scanning and MVM driver
MAC (virtual interface) management from Ilan, a CT-kill (critical
temperature) fix from Eytan, and myself fixed three different little but
annoying bugs in the MVM driver.

The only ones I might not send for -rc1 are Emmanuel's debug patch, but
OTOH it should help greatly if there are any issues, and my own time
event debugging patch that I used to find the race condition but we
decided to keep it for the future."

For the mac80211 pull, Johannes says:

"Like iwlwifi-next, this would almost be suitable for rc1.

I have a fix for station management on non-TDLS drivers, a CAB queue
crash fix for mesh, a fix for an annoying (but harmless) warning, a
tracing fix and a documentation fix. Other than that, only a few mesh
cleanups."

Along with that is a fix for memory corruption in rtlwifi, an
orinoco_usb fix to avoid allocating a DMA buffer on the stack, an a
hostap fix to return -ENOMEM instead of -1 after a memory allocation
failure.  The remaining bits implement 802.11ac support for the mwifiex
driver -- I think that is still worth getting into 3.9.

Please let me know if there are problems!
