Create __fou_build_header and __gue_build_header. These implement the
protocol generic parts of building the fou and gue header.
fou_build_header and gue_build_header implement the IPv4 specific
functions and call the __*_build_header functions.

Consolidate all the ip_tunnel_encap definitions in one spot in the
header file. Also, move ip_encap_hlen and ip_tunnel_encap from
ip_tunnel.c to ip_tunnels.h so they call be called without a dependency
on ip_tunnel module. Similarly, move iptun_encaps to ip_tunnel_core.c.

This patch defines two new GSO definitions SKB_GSO_IPXIP4 and
SKB_GSO_IPXIP6 along with corresponding NETIF_F_GSO_IPXIP4 and
NETIF_F_GSO_IPXIP6. These are used to described IP in IP
tunnel and what the outer protocol is. The inner protocol
can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and
SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT
are removed (these are both instances of SKB_GSO_IPXIP4).
SKB_GSO_IPXIP6 will be used when support for GSO with IP
encapsulation over IPv6 is added.

When CONFIG_NET_CLS_ACT is disabled, we get a new warning in the mlx5
ethernet driver because the tc_for_each_action() loop never references
the iterator:
mellanox/mlx5/core/en_tc.c: In function 'mlx5e_stats_flower':
mellanox/mlx5/core/en_tc.c:431:20: error: unused variable 'a' [-Werror=unused-variable]
struct tc_action *a;
This changes the dummy tc_for_each_action() macro by adding a
cast to void, letting the compiler know that the variable is
intentionally declared but not used here. I could not come up
with a nicer workaround, but this seems to do the trick.

Pull ARC updates from Vineet Gupta:
"We have a relatively big changeset for ARC for 4.7.
The highlight is support for EZChip (now Mellanox) NPS-400 network
processor, a 400-Gb throughput C-programmable packet processor based
on ARC700 cores from Synopsys. See
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
irq domains, missing irq domain lookup, hard coded timer irqs...)
Summary:
- Support for EZChip (now Mellanox) NPS-400 Network processor based
on ARC700
- NPS interrupt controller and clocksource drivers
- ARC timers probed off DT
- ARC iqrchips switching to linear domain (upgrade from legacy
domains)"

Pull security subsystem updates from James Morris:
"Highlights:
- A new LSM, "LoadPin", from Kees Cook is added, which allows forcing
of modules and firmware to be loaded from a specific device (this
is from ChromeOS, where the device as a whole is verified
cryptographically via dm-verity).
This is disabled by default but can be configured to be enabled by
default (don't do this if you don't know what you're doing).

Pull tracing updates from Steven Rostedt:
"This includes two new updates for the ftrace infrastructure.
- 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
- 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"

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

Pull ARM DT updates from Arnd Bergmann:
"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

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"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"

Pull parallel filesystem directory handling update from Al Viro.
This is the main parallel directory work by Al that makes the vfs layer
able to do lookup and readdir in parallel within a single directory.
That's a big change, since this used to be all protected by the
directory inode mutex.
The inode mutex is replaced by an rwsem, and serialization of lookups of
a single name is done by a "in-progress" dentry marker.
The series begins with xattr cleanups, and then ends with switching
filesystems over to actually doing the readdir in parallel (switching to
the "iterate_shared()" that only takes the read lock).
A more detailed explanation of the process from Al Viro:
"The xattr work starts with some acl fixes, then switches ->getxattr to
passing inode and dentry separately. This is the point where the
things start to get tricky - that got merged into the very beginning
of the -rc3-based #work.lookups, to allow untangling the
security_d_instantiate() mess. The xattr work itself proceeds to
switch a lot of filesystems to generic_...xattr(); no complications
there.
After that initial xattr work, the series then does the following:
- untangle security_d_instantiate()
- convert a bunch of open-coded lookup_one_len_unlocked() to calls of
that thing; one such place (in overlayfs) actually yields a trivial
conflict with overlayfs fixes later in the cycle - overlayfs ended
up switching to a variant of lookup_one_len_unlocked() sans the
permission checks. I would've dropped that commit (it gets
overridden on merge from #ovl-fixes in #for-next; proper resolution
is to use the variant in mainline fs/overlayfs/super.c), but I
didn't want to rebase the damn thing - it was fairly late in the
cycle...
- some filesystems had managed to depend on lookup/lookup exclusion
for *fs-internal* data structures in a way that would break if we
relaxed the VFS exclusion. Fixing hadn't been hard, fortunately.
- core of that series - parallel lookup machinery, replacing
->i_mutex with rwsem, making lookup_slow() take it only shared. At
that point lookups happen in parallel; lookups on the same name
wait for the in-progress one to be done with that dentry.
Surprisingly little code, at that - almost all of it is in
fs/dcache.c, with fs/namei.c changes limited to lookup_slow() -
making it use the new primitive and actually switching to locking
shared.
- parallel readdir stuff - first of all, we provide the exclusion on
per-struct file basis, same as we do for read() vs lseek() for
regular files. That takes care of most of the needed exclusion in
readdir/readdir; however, these guys are trickier than lookups, so
I went for switching them one-by-one. To do that, a new method
'->iterate_shared()' is added and filesystems are switched to it
as they are either confirmed to be OK with shared lock on directory
or fixed to be OK with that. I hope to kill the original method
come next cycle (almost all in-tree filesystems are switched
already), but it's still not quite finished.
- several filesystems get switched to parallel readdir. The
interesting part here is dealing with dcache preseeding by readdir;
that needs minor adjustment to be safe with directory locked only
shared.
Most of the filesystems doing that got switched to in those
commits. Important exception: NFS. Turns out that NFS folks, with
their, er, insistence on VFS getting the fuck out of the way of the
Smart Filesystem Code That Knows How And What To Lock(tm) have
grown the locking of their own. They had their own homegrown
rwsem, with lookup/readdir/atomic_open being *writers* (sillyunlink
is the reader there). Of course, with VFS getting the fuck out of
the way, as requested, the actual smarts of the smart filesystem
code etc. had become exposed...
- do_last/lookup_open/atomic_open cleanups. As the result, open()
without O_CREAT locks the directory only shared. Including the
->atomic_open() case. Backmerge from #for-linus in the middle of
that - atomic_open() fix got brought in.
- then comes NFS switch to saner (VFS-based ;-) locking, killing the
homegrown "lookup and readdir are writers" kinda-sorta rwsem. All
exclusion for sillyunlink/lookup is done by the parallel lookups
mechanism. Exclusion between sillyunlink and rmdir is a real rwsem
now - rmdir being the writer.
Result: NFS lookups/readdirs/O_CREAT-less opens happen in parallel
now.
- the rest of the series consists of switching a lot of filesystems
to parallel readdir; in a lot of cases ->llseek() gets simplified
as well. One backmerge in there (again, #for-linus - rockridge
fix)"

The problem is that fib_info->nh is [0] so the struct fib_info
allocation size depends on number of nexthops. If we just copy fib_info,
we do not copy the nexthops info and driver accesses memory which is not
ours.
Given the fact that fib4 does not defer operations and therefore it does
not need copy, just pass the pointer down to drivers as it was done
before.

Cut down on noise for mainstream users of the API and people doing build
testing by dropping the deprecated flag from regulator_can_change_voltage()
as it triggers even on the EXPORT_SYMBOL_GPL() which affects all builds
rather than just the remaining drivers with calls to it (for which fixes
are currently pending).
The function remains deprecated and is expected to be removed entirely
in v4.8.

This patch adds the necessary driver support for Management Firmware to
configure the device/firmware with the dcbx results. Management Firmware
is responsible for communicating the DCBX and driving the negotiation,
but the driver has responsibility of receiving async notification and
configuring the results in hw/fw. This patch also adds the dcbx support for
future protocols (e.g., FCoE) as preparation to their imminent submission.

Pull power management updates from Rafael Wysocki:
"The majority of changes go into the cpufreq subsystem this time.
To me, quite obviously, the biggest ticket item is the new "schedutil"
governor. Interestingly enough, it's the first new cpufreq governor
since the beginning of the git era (except for some out-of-the-tree
ones).
There are two main differences between it and the existing governors.
First, it uses the information provided by the scheduler directly for
making its decisions, so it doesn't have to track anything by itself.
Second, it can invoke drivers (supporting that feature) to adjust CPU
performance right away without having to spawn work items to be
executed in process context or similar. Currently, the acpi-cpufreq
driver is the only one supporting that mode of operation, but then it
is used on a large number of systems.
The "schedutil" governor as included here is very simple and mostly
regarded as a foundation for future work on the integration of the
scheduler with CPU power management (in fact, there is work in
progress on top of it already). Nevertheless it works and the
preliminary results obtained with it are encouraging.
There also is some consolidation of CPU frequency management for ARM
platforms that can add their machine IDs the the new stub dt-platdev
driver now and that will take care of creating the requisite platform
device for cpufreq-dt, so it is not necessary to do that in platform
code any more. Several ARM platforms are switched over to using this
generic mechanism.
In addition to that, the intel_pstate driver is now going to respect
CPU frequency limits set by the platform firmware (or a BMC) and
provided via the ACPI _PPC object.
The devfreq subsystem is getting a new "passive" governor for SoCs
subsystems that will depend on somebody else to manage their voltage
rails and its support for Samsung Exynos SoCs is consolidated.
The rest is support for new hardware (Intel Broxton support in
intel_idle for one example), bug fixes, optimizations and cleanups in
a number of places.
Specifics:
- New cpufreq "schedutil" governor (making decisions based on CPU
utilization information provided by the scheduler and capable of
switching CPU frequencies right away if the underlying driver
supports that) and support for fast frequency switching in the
acpi-cpufreq driver (Rafael Wysocki)
- Consolidation of CPU frequency management on ARM platforms allowing
them to get rid of some platform-specific boilerplate code if they
are going to use the cpufreq-dt driver (Viresh Kumar, Finley Xiao,
Marc Gonzalez)
- Support for ACPI _PPC and CPU frequency limits in the intel_pstate
driver (Srinivas Pandruvada)
- Fixes and cleanups in the cpufreq core and generic governor code
(Rafael Wysocki, Sai Gurrappadi)
- intel_pstate driver optimizations and cleanups (Rafael Wysocki,
Philippe Longepe, Chen Yu, Joe Perches)
- cpufreq powernv driver fixes and cleanups (Akshay Adiga, Shilpasri
Bhat)

- ACPI cpufreq driver cleanups (Viresh Kumar)
- Assorted cpufreq driver updates (Ashwin Chaugule, Geliang Tang,
Javier Martinez Canillas, Paul Gortmaker, Sudeep Holla)
- Assorted cpufreq fixes and cleanups (Joe Perches, Arnd Bergmann)
- Fixes and cleanups in the OPP (Operating Performance Points)
framework, mostly related to OPP sharing, and reorganization of
OF-dependent code in it (Viresh Kumar, Arnd Bergmann, Sudeep Holla)
- New "passive" governor for devfreq (for SoC subsystems that will
rely on someone else for the management of their power resources)
and consolidation of devfreq support for Exynos platforms, coding
style and typo fixes for devfreq (Chanwoo Choi, MyungJoo Ham)
- PM core fixes and cleanups, mostly to make it work better with the
generic power domains (genpd) framework, and updates for that
framework (Ulf Hansson, Thierry Reding, Colin Ian King)
- Intel Broxton support for the intel_idle driver (Len Brown)
