Linus Torvalds cc998ff881 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking changes from David Miller:
 "Noteworthy changes this time around:

   1) Multicast rejoin support for team driver, from Jiri Pirko.

   2) Centralize and simplify TCP RTT measurement handling in order to
      reduce the impact of bad RTO seeding from SYN/ACKs.  Also, when
      both timestamps and local RTT measurements are available prefer
      the later because there are broken middleware devices which
      scramble the timestamp.

      From Yuchung Cheng.

   3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel
      memory consumed to queue up unsend user data.  From Eric Dumazet.

   4) Add a "physical port ID" abstraction for network devices, from
      Jiri Pirko.

   5) Add a "suppress" operation to influence fib_rules lookups, from
      Stefan Tomanek.

   6) Add a networking development FAQ, from Paul Gortmaker.

   7) Extend the information provided by tcp_probe and add ipv6 support,
      from Daniel Borkmann.

   8) Use RCU locking more extensively in openvswitch data paths, from
      Pravin B Shelar.

   9) Add SCTP support to openvswitch, from Joe Stringer.

  10) Add EF10 chip support to SFC driver, from Ben Hutchings.

  11) Add new SYNPROXY netfilter target, from Patrick McHardy.

  12) Compute a rate approximation for sending in TCP sockets, and use
      this to more intelligently coalesce TSO frames.  Furthermore, add
      a new packet scheduler which takes advantage of this estimate when
      available.  From Eric Dumazet.

  13) Allow AF_PACKET fanouts with random selection, from Daniel
      Borkmann.

  14) Add ipv6 support to vxlan driver, from Cong Wang"

     per-process VMA pieces, watermark reworks, convert to generic hdmi
     infoframes, encoder reworking, fastboot support,

   - radeon:

     CIK PM support, remove 3d blit code in favour of DMA engines,
     Berlin GPU support, HDMI audio fixes

   - nouveau:

     secondary GPU power down support for optimus laptops, lots of
     fixes, use MSI, VP3 engine support

Chanho Park 319477f35e drm/exynos: add device tree support for rotator
The exynos4 platform is only dt-based since 3.10, we should convert driver data
and ids to dt-based parsing methods. The rotator driver has a limit table to get
size limit of input picture. Each SoCs has slightly different limit value
compared with any others.
For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have
8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size
for its X/Y axis. Thus, we should keep different tables for each of them.
This patch also includes desciptions of each nodes for the rotator and specifies
a example how to bind it.

Linus Torvalds ae67d9a888 New features for 3.12:
* Added aggressive extent caching using the extent status tree.  This
   can actually decrease memory usage in read-mostly workloads since
   the information is much more compactly stored in the extent status
   tree than if we had to keep the extent tree metadata blocks in the
   buffer cache.  This also improves Asynchronous I/O since it is it
   makes much less likely that we need to do metadata I/O to lookup the
   extent tree information.
 * Improve the recovery after corrupted allocation bitmaps are found
   when running in errors=ignore mode.
 
 Also fixed some writeback vs. truncate races when using a blocksize
 less than the page size.

Linus Torvalds aa7054f5a5 Bulk pin control changes for the v3.12 series:
- Refactorings for generic pin config handling in the core.
 
 - Factor out a set of device tree utilities for use in all
   drivers, to parse and allocate maps from the device tree.
 
 - Some fixes to the core such as more nitpicky locking.
 
 - Pushed down config array iteration into the drivers.
   This patch is necessary for drivers that want to iterate
   over configs and pile up a stack of alterations to the
   same register(s), or if the driver wants to take a local
   spinlock when committing the configuration.
 
 - A new driver for the Texas Instruments Palmas PMIC by
   Laxman Dewangan. This is used on the Tegra systems.
 
 - A major cleanup and modernization of the PFC (Super Hitachi
   and ARM SHmobile) pin controller and subdrivers.
 
 - Support for the A20 and A31 sunxi (AllWinner) SoCs.
 
 - A huge pile of fixes and cleanups: Axel Lin, Jingoo Han
   Dan Carpenter, Julia Lawall and Sachin Kamat did an
   excellent job here.

 "Here is the bulk of pin control changes for the v3.12 series.  Most of
  the relevant information is in the tag.

  I merged in v3.11-rc7 last week to get rid of a largeish conflict
  within the sunxi (AllWinner) driver in linux-next and fix up the
  non-trivial merge the right way.  That driver had a rather large fix
  adding locking late in the release cycle.

  Overall the bulk changes this time is cleanups and refactorings and
  not much new features, which is nice.

   - Refactorings for generic pin config handling in the core.

   - Factor out a set of device tree utilities for use in all drivers,
     to parse and allocate maps from the device tree.

   - Some fixes to the core such as more nitpicky locking.

   - Pushed down config array iteration into the drivers.

     This patch is necessary for drivers that want to iterate over
     configs and pile up a stack of alterations to the same register(s),
     or if the driver wants to take a local spinlock when committing the
     configuration.

   - A new driver for the Texas Instruments Palmas PMIC by Laxman
     Dewangan.  This is used on the Tegra systems.

   - A major cleanup and modernization of the PFC (Super Hitachi and ARM
     SHmobile) pin controller and subdrivers.

   - Support for the A20 and A31 sunxi (AllWinner) SoCs.

   - A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan
     Carpenter, Julia Lawall and Sachin Kamat did an excellent job here"

David S. Miller e7abfe4092 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:

====================
Please accept this batch of updates intended for the 3.12 stream.

For the mac80211 bits, Johannes says this:

"This time I have various improvements all over the place: IBSS, mesh,
testmode, AP client powersave handling, one of the rare rfkill patches
and some code cleanup."

Also for mac80211:

"And I also have some more changes for -next, just a few small fixes and
improvements, nothing really stands out."

And for iwlwifi:

"This time I have some powersave work (notably uAPSD support), CQM
offloads, support for a new firmware API and various code cleanups."

Regarding the Bluetooth bits, Gustavo says:

"Patches to 3.12, here we have:

* implementation of a proper tty_port for RFCOMM devices, this fixes some
issues people were seeing lately in the kernel.
* Add voice_setting option for SCO, it is used for SCO Codec selection
* bugfixes, small improvements and clean ups"

For the NFC bits, Samuel says:

"With this one we have:

- A few pn533 improvements and minor fixes. Testing our pn533 driver
  against Google's NCI stack triggered a few issues that we fixed now.
  We also added Tx fragmentation support to this driver.

- More NFC secure element handling. We added a GET_SE netlink command
  for getting all the discovered secure elements, and we defined 2
  additional secure element netlink event (transaction and connectivity).
  We also fixed a couple of typos and copy-paste bugs from the secure
  element handling code.

- Firmware download support for the pn544 driver. This chipset can enter a
  special mode where it's waiting for firmware blobs to replace the
  already flashed one. We now support that mode."

With repect to the ath tree, Kalle says:

"New features in ath10k are rx/tx checsumming in hw and survey scan
implemented by Michal. Also he made fixes to different areas of the
driver, most notable being fixing the case when using two streams and
reducing the number of interface combinations to avoid firmware crashes.
Bartosz did a clean related to how we handle SoC power save in PCI
layer.

For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent
crashes."

I also pulled the wireless tree into wireless-next to support a
request from Johannes.  On top of all that, there are the usual
sort of driver updates.  The mwifiex, brcmfmac, brcmsmac, ath9k,
and rt2x00 drivers all get some attention, as does the bcma bus and
a few other random bits here and there.

Linus Torvalds ec1882a939 regulator: Updates for v3.12
Not much exciting going on with the regulator API this time around, lots
 of driver fixes and enhancements - the main thing is the addition of a
 new API to help make the stubbing code do the right thing for missing
 regulator mappings.
 
 Highlights:
 
  - A new regulator_get_optional() API call for regulators that can be
    absent in normal operation.  This currently does nothing but will be
    used to improve the stubbing code for unspecified regulators, helping
    avoid some of the issues we've seen with adding new regulator support.
  - Helpers for devices with multiple linear ranges of voltages in the
    same regulator.
  - Moved the helpers into a separate file since core.c is getting rather
    large.
  - New drivers for Dialog DA9210 and DA9063, Freescale pfuze100 and
    Marvell 88pm800.
