Pull writeback error handling updates from Jeff Layton:
"This pile continues the work from last cycle on better tracking
writeback errors. In v4.13 we added some basic errseq_t infrastructure
and converted a few filesystems to use it.
This set continues refining that infrastructure, adds documentation,
and converts most of the other filesystems to use it. The main
exception at this point is the NFS client"

Pull power management updates from Rafael Wysocki:
"This time (again) cpufreq gets the majority of changes which mostly
are driver updates (including a major consolidation of intel_pstate),
some schedutil governor modifications and core cleanups.
There also are some changes in the system suspend area, mostly related
to diagnostics and debug messages plus some renames of things related
to suspend-to-idle. One major change here is that suspend-to-idle is
now going to be preferred over S3 on systems where the ACPI tables
indicate to do so and provide requsite support (the Low Power Idle S0
_DSM in particular). The system sleep documentation and the tools
related to it are updated too.
The rest is a few cpuidle changes (nothing major), devfreq updates,
generic power domains (genpd) framework updates and a few assorted
modifications elsewhere.
Specifics:
- Drop the P-state selection algorithm based on a PID controller from
intel_pstate and make it use the same P-state selection method
(based on the CPU load) for all types of systems in the active mode
(Rafael Wysocki, Srinivas Pandruvada).
- Rework the cpufreq core and governors to make it possible to take
cross-CPU utilization updates into account and modify the schedutil
governor to actually do so (Viresh Kumar).
- Clean up the handling of transition latency information in the
cpufreq core and untangle it from the information on which drivers
cannot do dynamic frequency switching (Viresh Kumar).
- Add support for new SoCs (MT2701/MT7623 and MT7622) to the mediatek
cpufreq driver and update its DT bindings (Sean Wang).
- Modify the cpufreq dt-platdev driver to autimatically create
cpufreq devices for the new (v2) Operating Performance Points (OPP)
DT bindings and update its whitelist of supported systems (Viresh
Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen, Finley
Xiao).
- Add support for Ux500 to the cpufreq-dt driver and drop the
obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann).
- Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem
Nguyen).
- Fix and clean up assorted issues in the cpufreq drivers and core
(Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva,
Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla).
- Update the IO-wait boost handling in the schedutil governor to make
it less aggressive (Joel Fernandes).
- Rework system suspend diagnostics to make it print fewer messages
to the kernel log by default, add a sysfs knob to allow more
suspend-related messages to be printed and add Low Power S0 Idle
constraints checks to the ACPI suspend-to-idle code (Rafael
Wysocki, Srinivas Pandruvada).
- Prefer suspend-to-idle over S3 on ACPI-based systems with the
ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
interface present in the ACPI tables (Rafael Wysocki).
- Update documentation related to system sleep and rename a number of
items in the code to make it cleare that they are related to
suspend-to-idle (Rafael Wysocki).
- Export a variable allowing device drivers to check the target
system sleep state from the core system suspend code (Florian
Fainelli).
- Clean up the cpuidle subsystem to handle the polling state on x86
in a more straightforward way and to use %pOF instead of full_name
(Rafael Wysocki, Rob Herring).
- Update the devfreq framework to fix and clean up a few minor issues
(Chanwoo Choi, Rob Herring).
- Extend diagnostics in the generic power domains (genpd) framework
and clean it up slightly (Thara Gopinath, Rob Herring).
- Fix and clean up a couple of issues in the operating performance
points (OPP) framework (Viresh Kumar, Waldemar Rymarkiewicz).
- Add support for RV1108 to the rockchip-io Adaptive Voltage Scaling
(AVS) driver (David Wu).
- Fix the usage of notifiers in CPU power management on some
platforms (Alex Shi).
- Update the pm-graph system suspend/hibernation and boot profiling
utility (Todd Brandt).
- Make it possible to run the cpupower utility without CPU0 (Prarit
Bhargava)"

Pull GPIO updates from Linus Walleij:
"This is the bulk of the GPIO changes for the v4.14 cycle.
Not so much changes this time, phew. David Daney and Bartosz
Golaszewski did all the really interesting work in infrastructure
improvement across GPIO and IRQ core, hats off for them and to tglx
and Marc Z for general help with these patch sets.
Core changes:
- Allow the GPIO irqchip to allocate IRQs dynamically. This is an
important change on systems where only a restricted number of IRQs,
lesser than the number of GPIO lines, can be utilized. Now we can
allocate these on a first-come-first-served basis instead of
hogging up valuable IRQ lines.
- Serious fix-up of the kerneldoc documentation and inclusion into
the kerneldoc builds.
- Pulled in the IRQ simulator from the IRQ core tree and use this in
the GPIO mockup driver for exhaustive testing of interrupt
abilities.
New drivers:
- New driver for ThunderX and OCTEON-TX. This is especially
interesting as it picks up improvements from the IRQ core that
allow us to handle fasteoi ACKs upwards in a hierarchy when there
are IRQ flag latches on several levels in a hierarchy. Very
interesting work here.
- New subdriver for Renesas R-Car r8a7745 (RZ/G1E).
Misc:
- Several fixes and improvements for Xilinx Zynq GPIO.
- Support an enablement GPIO for the 74x164 GPIO.
- Switch a bunch of chips to use devres to allocate irq descriptors.
- A bunch of constification fixes"

Pull arm64 updates from Catalin Marinas:
- VMAP_STACK support, allowing the kernel stacks to be allocated in the
vmalloc space with a guard page for trapping stack overflows. One of
the patches introduces THREAD_ALIGN and changes the generic
alloc_thread_stack_node() to use this instead of THREAD_SIZE (no
functional change for other architectures)
- Contiguous PTE hugetlb support re-enabled (after being reverted a
couple of times). We now have the semantics agreed in the generic mm
layer together with API improvements so that the architecture code
can detect between contiguous and non-contiguous huge PTEs
- Initial support for persistent memory on ARM: DC CVAP instruction
exposed to user space (HWCAP) and the in-kernel pmem API implemented
- raid6 improvements for arm64: faster algorithm for the delta syndrome
and implementation of the recovery routines using Neon
- FP/SIMD refactoring and removal of support for Neon in interrupt
context. This is in preparation for full SVE support
- PTE accessors converted from inline asm to cmpxchg so that we can use
LSE atomics if available (ARMv8.1)

When migrating guests around we need to know the active priorities to
ensure functional virtual interrupt prioritization by the GIC.
This commit clarifies the API and how active priorities of interrupts in
different groups are represented, and implements the accessor functions
for the uaccess register range.
We live with a slight layering violation in accessing GICv3 data
structures from vgic-mmio-v2.c, because anything else just adds too much
complexity for us to deal with (it's not like there's a benefit
elsewhere in the code of an intermediate representation as is the case
with the VMCR). We accept this, because while doing v3 processing from
a file named something-v2.c can look strange at first, this really is
specific to dealing with the user space interface for something that
looks like a GICv2.

Most tables there don't fit on 80 columns. Some are very big.
While those tables are actually generated via scripts, every
time a new board is added, the entire table could be reformatted.
>From the diffstat PoV, that's bad, as it is hard to see what
happened.
One such example is at changeset 4868f6e1fce6 ("media:
em28xx-cardlist.rst: update to reflect last changes"):
The USB ID for "Plextor ConvertX PX-AV100U" was added to card
number 9, with caused the entire table to be reformatted.
So, instead, use flat-tables. While here, fix PDF output,
by adding tablecolumns to the tables that need it.

Commit 70b074df4ed1 ("media: fix pdf build with Spinx 1.6") caused
a regression at Sphinx 1.4 PDF build: although it produces a full
document in batch mode, it returns errors on interactive mode:
[63]
Runaway argument?
{\relax
! Paragraph ended before \multicolumn was complete.
<to be read again>
\par
l.7703 \hline\end{tabulary}
The error seems to be due to some bug at Sphinx PDF output:
when multicolumns is used, it doesn't accept an empty string.
Just removing the :cpan:`1` and replacing by two empty
columns fix the issue.

In the past, V4L2 versions were 0.x.y, but that changed years
ago. Since Kernel 3.1, however, the numbering schema was changed
to match the Kernel version.
However, the presented example still uses the old numerating
