1dad640b9e wext: reformat struct/union declarations 
Everytime I need to look for these, my usual strategy fails
because it assumes the right formatting. Fix the formatting
here to make it consistent with the rest of the kernel.

019ae3a918 cfg80211: Advertise extended capabilities per interface type to userspace 
The driver extended capabilities may differ for different
interface types which the userspace needs to know (for
example the fine timing measurement initiator and responder
bits might differ for a station and AP). Add a new nl80211
attribute to provide extended capabilities per interface type
to userspace.

bf1ecd2105 cfg80211: Allow cfg80211_connect_result() errors to be distinguished 
Previously, the status parameter to cfg80211_connect_result() was
documented as using WLAN_STATUS_UNSPECIFIED_FAILURE (1) when the real
status code for the failure is not known. This value can be used by an
AP (and often is) and as such, user space cannot distinguish between
explicitly rejected authentication/association and not being able to
even try to associate or not receiving a response from the AP.

Add a new inline function, cfg80211_connect_timeout(), to be used when
the driver knows that the connection attempt failed due to a reason
where connection could not be attempt or no response was received from
the AP. The internal functions now allow a negative status value (-1) to
be used as an indication of this special case. This results in the
NL80211_ATTR_TIMED_OUT to be added to the NL80211_CMD_CONNECT event to
allow user space to determine this case was hit. For backwards
compatibility, NL80211_STATUS_CODE with the value
WLAN_STATUS_UNSPECIFIED_FAILURE is still indicated in the event in such
a case.

100cb9ff40 mac80211_hwsim: Allow managing radios from non-initial namespaces 
While wiphys can be moved into network namespaces over nl80211, the
creation and removal of hwsim radios is currently limited to the initial
namespace. This patch allows management of namespaced radios from the
owning namespace by setting genetlink netnsok.

To prevent two arbitrary namespaces to communicate over the simulated
shared medium, radios are separated by netgroups. Each radio created in
the same namespace lives in the same netgroup and hence can communicate
with other radios in that group. When moving radios to other namespaces,
the netgroup is preserved, so two radios having the same netgroup can
communicate even if not in the same namespace; This allows a controlling
namespace to create radios and move them to other namespaces for
communication.

When a net namespace owning a radio exits, the radio is destroyed unless
it was created in the initial network namespace. This keeps the previous
behavior by returning them to the init namespace, but prevents unprivileged
users from creating radios in the initial namespace.

5617c6cd6f nl80211: Allow privileged operations from user namespaces 
While a wiphy can be transferred to network namespaces, a process having
CAP_NET_ADMIN in a non-initial user namespace can not administrate such
devices due to the genetlink GENL_ADMIN_PERM restrictions.

For openvswitch having the same issue, a new GENL_UNS_ADMIN_PERM flag has
been introduced, commit 4a92602aa1 ("openvswitch: allow management from
inside user namespaces"). This patch changes all privileged operations
operating on a wiphy, dev or wdev to allow their administration using the
same mechanism. All operations use either NEED_WIPHY, NEED_WDEV or
NEED_NETDEV, which implies a namespace aware lookup of the device. The only
exception is NL80211_CMD_SET_WIPHY, which explicitly uses a namespace aware
phy lookup.

        http://www.mellanox.com/related-docs/prod_npu/PB_NPS-400.pdf

  Also present are irqchip and clocksource drivers for NPS as agreed
  with respective maintainers to go via ARC tree due to an soc header
  dependency.  I have the needed ACKs from Jason, Marc, Daniel.  You
  might run into a trivial merge conflict in drivers/irqchip/*

  This EZChip platform support required some deep changes in ARC
  architecture code and also opportunity to cleanup past sins (legacy

2600a46ee0 This includes two new updates for the ftrace infrastructure. 
1) With the changing of the code for filtering events by pid, from
   a list of pids to a bitmask, we can now easily implement following
   forks. With a new tracing option "event-fork" which, when set, will
   have tasks with pids in set_event_pid, when they fork, to have their
   child pids added to set_event_pid and the child will be traced as well.
 
   Note, if "event-fork" is set and a task with its pid in set_event_pid
   exits, its pid will be removed from set_event_pid
 
 2) The addition of Tom Zanussi's hist triggers. This includes a very
    thorough documentatino on how to use the hist triggers with events.
    This introduces a quick and easy way to get histogram data from
    events and their fields.
 
 Some other cleanups and updates were added as well. Like Masami Hiramatsu
 added test cases for the event trigger and hist triggers. Also I added
 a speed up of filtering by using a temp buffer when filters are set.

4a5219edcd ARM: SoC driver updates for v4.7 
Driver updates for ARM SoCs, these contain various things that touch
 the drivers/ directory but got merged through arm-soc for practical
 reasons. For the most part, this is now related to power management
 controllers, which have not yet been abstracted into a separate
 subsystem, and typically require some code in drivers/soc or arch/arm
 to control the power domains.
 
 Another large chunk here is a rework of the NVIDIA Tegra USB3.0
 support, which was surprisingly tricky and took a long time to
 get done.
 
 Finally, reset controller handling as always gets merged through here
 as well.

2ec3240fd7 ARM: 64-bit DT updates for v4.7 
We continue ramping up platform support for 64-bit ARM machines,
 with 111 individual non-merge changesets touching 21 platforms.
 
 The LG1312 platform is completely new and is the first ARM
 platform by LG that we support in the mainline kernel. Two other
 SoCs got added that are updated versions of existing SoC
 families, so the port mainly consists of new dts files:
 - The Hisilicon Hip06/D03 is the latest server platform
   from Huawei/Hisilicon, and follows the Hip05/D02 platform.
 - Rockchip RK3399 follows the 32-bit RK3288 that is popular
   in low-end Chromebooks and the 64-bit RK3368 that is mainly
   found in chinese Android TV boxes.
 
 The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620)
 gets a long-awaited overhaul with a lot of devices enabled in
 the DT, so it should be much more usable with a mainline kernel
 now. See also
 https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd
 
 A lot of work went into enabling new device drivers on existing
 machines, but we also have a couple of new commercially
 available machines:
 
 - Google Pixel C laptop based on Tegra210
 - Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905)
 - Geekbuying GeekBox based on Rockchip RK3368
 
 And finally, a couple of reference or development platforms
 that are not end-user platforms but are used for trying out
 the respective SoC platforms:
 
 - Amlogic Meson GXBB P200 and P201 development systems
 - NXP Layerscape 1043A QDS development board
 - Hisilicon Hip06 D03 server board, as mentioned above
 - LG1312 Reference Design
 - RK3399 Evaluation Board

Pull ARM 64-bit DT updates from Arnd Bergmann:
 "We continue ramping up platform support for 64-bit ARM machines, with
  111 individual non-merge changesets touching 21 platforms.

  The LG1312 platform is completely new and is the first ARM platform by
  LG that we support in the mainline kernel.  Two other SoCs got added
  that are updated versions of existing SoC families, so the port mainly
  consists of new dts files:

   - The Hisilicon Hip06/D03 is the latest server platform from
     Huawei/Hisilicon, and follows the Hip05/D02 platform.

   - Rockchip RK3399 follows the 32-bit RK3288 that is popular in
     low-end Chromebooks and the 64-bit RK3368 that is mainly found in
     chinese Android TV boxes.

  The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620) gets a
  long-awaited overhaul with a lot of devices enabled in the DT, so it
  should be much more usable with a mainline kernel now.  See also

     https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd

  A lot of work went into enabling new device drivers on existing
  machines, but we also have a couple of new commercially available
  machines:

   - Google Pixel C laptop based on Tegra210
   - Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905)
   - Geekbuying GeekBox based on Rockchip RK3368

  And finally, a couple of reference or development platforms that are
  not end-user platforms but are used for trying out the respective SoC
  platforms:

   - Amlogic Meson GXBB P200 and P201 development systems
   - NXP Layerscape 1043A QDS development board
   - Hisilicon Hip06 D03 server board, as mentioned above
   - LG1312 Reference Design
   - RK3399 Evaluation Board"

f7df9be067 ARM: DT updates for v4.7 
These are all the updates to device tree files for 32-bit platforms,
 which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
 changesets, 450 files changed, 23340 insertions, 5216 deletions.
 
 The three platforms that are added with the "soc" branch are here as well,
 and we add some related machine files:
 
 - For Aspeed AST2400/AST2500, we get the evaluation platform and
   the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
 - For Oxnas 810SE, the Western Digital "My Book World Edition"
   is added as the only platform at the moment.
 - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7)
   are supported
 
 On the ARM Realview development platform, we now support all machines
 with device tree, previously only the board files were supported, which
 in turn will likely be removed soon.
 
 Qualcomm IPQ4019 is the second generation ARM based "Internet Processor",
 following the IPQ806x that is used in many high-end WiFi routers. This one
 integrates two ath10k wifi radios that were previously on separate chips.
 
 Other boards that got added for existing chips are:
 
 - On Ti OMAP family:
   - Amazon Kindle Fire, first generation, tablet and ebook reader

9896c7b57e ARM: SoC platform updates for v4.7 
We get support for three new 32-bit SoC platforms this time. The amount
 of changes in arch/arm for any of them is miniscule, as all the
 interesting code is in device driver subsystems (irqchip, clk, pinctrl,
 ...) these days. I'm listing them here, as the addition of the Kconfig
 statement is the main relevant milestone for a new platform. In each
 case, some drivers are are shared with existing platforms, while
 other drivers are added for v4.7 as well, or come in a later release.
 
 - The Aspeed platform is probably the most interesting one, this is
   what most whitebox servers use as their baseboard management
   controller. We get support for the very common ast2400 and ast2500
   SoCs. The OpenBMC project focuses on this chip, and the LWN
   article about their ELC 2016 presentation at
   https://lwn.net/Articles/683320/ triggered the submission, but the
   code comes from IBM's OpenPOWER team rather than the team at
   Facebook. There are still a lot more drivers that need to get added
   over time, and I hope both teams can work together on that.
 
 - OXNAS is an old platform for Network Attached Storage devices
   from Oxford Semiconductor. There are models with ARM10 (!) and
   ARM11MPCore cores, but for now, we only support the original ARM9
   based versions.
   The product lineup was subsequently part of PLX, Avago and now the
   new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
   has some more information.
 
 - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
   cores and is related to the existing Realview / Versatile Express
   lineup, but without MMU. We now support various NOMMU platforms,
   so adding a new one is fairly straightforward.
   http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
   has detailed information about the platform.
 
 Other noteworthy updates:
 
 - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux
   are now maintaining the platform. This is an older ARM9 based
   platform from NXP (not Freescale), but it remains in use in embedded
   markets.
 
 - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both
   32-bit and 64-bit ARM, and started contributing some patches.
 
 - As is often the case, work on the OMAP platforms makes up the bulk of
   the actual SoC code changes in arch/arm, but there isn't a lot of
   that either.

f2b1e0f638 ARM: SoC cleanups and fixes for v4.7 
Traditionally we've had two separate branches for cleanups and non-critical
 bug fixes, but both of these got smaller with each release and the differences
 are rather unclear now, so it seems more appropriate to have a combined
 branch.
 
 The most notably change is for OMAP, which gets a small rework to simplify
 handling of the AUXDATA mechanism used on machines that are not completely
 DT based yet, along with other work that is used as preparation for dropping
 the legacy board files.

0e034f5c4b iwlwifi: fix mis-merge that breaks the driver 
My laptop that uses the intel 7680 iwlwifi module would no longer
connects to the network.  It would fail with a "Microcode SW error
detected." and spew out register state over and over again without ever
connecting to the network.

The cause is mis-merge in commit 909b27f706, where David seems to have
lost some of the changes to iwl_mvm_set_tx_cmd() from commit
5c08b0f502 ("iwlwifi: mvm: don't override the rate with the AMSDU
len").

The reason seems to be a conflict with commit d8fe484470 ("iwlwifi:
mvm: add support for new TX CMD API"), which touched a line adjacent to
the changes in 909b27f706.

David missed the fact that "info->driver_data[0]" had become
"skb_info->driver_data[0]".  Then he removed the skb_info because it was
unused.

This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.

9f54180109 xfs: concurrent readdir hangs on data buffer locks 
There's a three-process deadlock involving shared/exclusive barriers
and inverted lock orders in the directory readdir implementation.
It's a pre-existing problem with lock ordering, exposed by the
VFS parallelisation code.

process 1               process 2               process 3
---------               ---------               ---------
readdir
iolock(shared)
  get_leaf_dents
    iterate entries
       ilock(shared)
       map, lock and read buffer
       iunlock(shared)
       process entries in buffer
       .....
                                                readdir
                                                iolock(shared)
                                                  get_leaf_dents
                                                    iterate entries
                                                      ilock(shared)
                                                      map, lock buffer
                                                      <blocks>
                        finish ->iterate_shared
                        file_accessed()
                          ->update_time
                            start transaction
                            ilock(excl)
                            <blocks>
        .....
        finishes processing buffer
        get next buffer
          ilock(shared)
          <blocks>

And that's the deadlock.

Fix this by dropping the current buffer lock in process 1 before
trying to map the next buffer. This means we keep the lock order of
ilock -> buffer lock intact and hence will allow process 3 to make
progress and drop it's ilock(shared) once it is done.

776d7f1694 arc: axs103_smp: Fix CPU frequency to 100MHz for dual-core 
The most recent release of AXS103 [v1.1] is proven to work
at 100 MHz in dual-core mode so this change uses mentioned feature.
For that we:
 * Update axc003_idu.dtsi with mention of really-used CPU clock freq
 * Remove clock override in AXS platform code for dual-core HW

Note we're still leaving a hack for clock "downgrade" on early boot
for quad-core hardware.

Also note this change will break functionality of AXS103 v1.0 hardware.
That means all users of AXS103 __must__ upgrade their boards with the
most recent firmware.

1eccc6e152 This is the bulk of GPIO changes for kernel cycle v4.7: 
Core infrastructural changes:
 
 - Support for natively single-ended GPIO driver stages. This
   means that if the hardware has registers to configure open
   drain or open source configuration, we use that rather than
   (as we did before) try to emulate it by switching the line
   to an input to get high impedance. This is also documented
   throughly in Documentation/gpio/driver.txt for those of you
   who did not understand one word of what I just wrote.
 
 - Start to do away with the unnecessarily complex and
   unitelligible ARCH_REQUIRE_GPIOLIB and
   ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
   the time when the GPIO subsystem was unmaintained. Archs can
   now just select GPIOLIB and be done with it, cleanups to
   arches will trickle in for the next kernel. Some minor archs
   ACKed the changes immediately so these are included in this
   pull request.
 
 - Advancing the use of the data pointer inside the GPIO device
   for storing driver data by switching the PowerPC, Super-H
   Unicore and a few other subarches or subsystem drivers in
   ALSA SoC, Input, serial, SSB, staging etc to use it.
 
 - The initialization now reads the input/output state of the
   GPIO lines, so that each GPIO descriptor knows - if this
   callback is implemented - whether the line is input or
   output. This also reflects nicely in userspace "lsgpio".
 
 - It is now possible to name GPIO producer names, line names,
   from the device tree. (Platform data has been supported for
   a while.) I bet we will get a similar mechanism for ACPI
   one of those days. This makes is possible to get sensible
   producer names for e.g. GPIO rails in "lsgpio" in userspace.
 
 New drivers:
 
 - New driver for the Loongson1.
 
 - The XLP driver now supports Broadcom Vulcan ARM64.
 
 - The IT87 driver now supports IT8620 and IT8628.
 
 - The PCA953X driver now supports Galileo Gen2.
 
 Driver improvements:
 
 - MCP23S08 was switched to use the gpiolib irqchip helpers and
   now also suppors level-triggered interrupts.
 
 - 74x164 and RCAR now supports the .set_multiple() callback
 
 - AMDPT was converted to use generic GPIO.
 
 - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
   support the new single ended callback for open drain
   and in some cases open source.
 
 - Implement the .get_direction() callback for a few more drivers
   like PL061, Xgene.
 
 Cleanups:
 
 - Paul Gortmaker combed through the drivers and de-modularized
   those who are not really modules.
 
 - Move the GPIO poweroff DT bindings to the power subdir where
   they belong.
 
 - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
   point. That's what it is handling, nothing more, nothing less.

     unmaintained.

     Archs can now just select GPIOLIB and be done with it, cleanups to
     arches will trickle in for the next kernel.  Some minor archs ACKed
     the changes immediately so these are included in this pull request.

   - Advancing the use of the data pointer inside the GPIO device for
     storing driver data by switching the PowerPC, Super-H Unicore and
     a few other subarches or subsystem drivers in ALSA SoC, Input,
     serial, SSB, staging etc to use it.

   - The initialization now reads the input/output state of the GPIO
     lines, so that each GPIO descriptor knows - if this callback is
     implemented - whether the line is input or output.  This also
     reflects nicely in userspace "lsgpio".

   - It is now possible to name GPIO producer names, line names, from
     the device tree.  (Platform data has been supported for a while).
     I bet we will get a similar mechanism for ACPI one of those days.
     This makes is possible to get sensible producer names for e.g.
     GPIO rails in "lsgpio" in userspace.

  New drivers:

   - New driver for the Loongson1.

   - The XLP driver now supports Broadcom Vulcan ARM64.

   - The IT87 driver now supports IT8620 and IT8628.

   - The PCA953X driver now supports Galileo Gen2.

  Driver improvements:

   - MCP23S08 was switched to use the gpiolib irqchip helpers and now
     also suppors level-triggered interrupts.

   - 74x164 and RCAR now supports the .set_multiple() callback

   - AMDPT was converted to use generic GPIO.

   - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
     support the new single ended callback for open drain and in some
     cases open source.

   - Implement the .get_direction() callback for a few more drivers like
     PL061, Xgene.

  Cleanups:

   - Paul Gortmaker combed through the drivers and de-modularized those
     who are not really modules.

   - Move the GPIO poweroff DT bindings to the power subdir where they
     belong.

   - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
     point.  That's what it is handling, nothing more, nothing less"

e0d46f5c6e btrfs: Switch to generic xattr handlers 
The btrfs_{set,remove}xattr inode operations check for a read-only root
(btrfs_root_readonly) before calling into generic_{set,remove}xattr.  If
this check is moved into __btrfs_setxattr, we can get rid of
btrfs_{set,remove}xattr.

This patch applies to mainline, I would like to keep it together with
the other xattr cleanups if possible, though.  Could you please review?

Thanks,
Andreas

2b88fc21ca ubifs: Switch to generic xattr handlers 
Ubifs internally uses special inodes for storing xattrs. Those inodes
had NULL {get,set,remove}xattr inode operations before this change, so
xattr operations on them would fail. The super block's s_xattr field
would also apply to those special inodes. However, the inodes are not
visible outside of ubifs, and so no xattr operations will ever be
carried out on them anyway.
