Pull documentation fixes from Mauro Carvalho Chehab:
"This solves a series of broken links for files under Documentation,
and improves a script meant to detect such broken links (see
scripts/documentation-file-ref-check).
The changes on this series are:
- can.rst: fix a footnote reference;
- crypto_engine.rst: Fix two parsing warnings;
- Fix a lot of broken references to Documentation/*;
- improve the scripts/documentation-file-ref-check script, in order
to help detecting/fixing broken references, preventing
false-positives.
After this patch series, only 33 broken references to doc files are
detected by scripts/documentation-file-ref-check"

As files got renamed, their references broke.
Manually fix a series of broken refs at the DT bindings.

The specified locations are not right. Fix the wildcard logic
to point to the correct directories.
Without that, get-maintainer won't get things right:
$ ./scripts/get_maintainer.pl --no-git-fallback --no-r --no-n --no-l -f Documentation/devicetree/bindings/arm/cpu-enable-method/nuvoton,npcm750-smp
robh+dt@kernel.org (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)
mark.rutland@arm.com (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)

Those files got a manufacturer's name prepended and were moved around.
Adjust their references accordingly.
Also, due those movements, Documentation/devicetree/bindings/video
doesn't exist anymore.

omapfb is not maintained by me anymore, so drop my name from the
maintainers, and mark omapfb as orphan.
At some point in the future we should mark omapfb as obsolete, but there
are still some features supported by omapfb which are not supported by
omapdrm, so we're not there yet.

Pull RISC-V updates from Palmer Dabbelt:
"This contains some small RISC-V updates I'd like to target for 4.18.
They are all fairly small this time. Here's a short summary, there's
more info in the commits/merges:
- a fix to __clear_user to respect the passed arguments.
- enough support for the perf subsystem to work with RISC-V's ISA
defined performance counters.
- support for sparse and cleanups suggested by it.
- support for R_RISCV_32 (a relocation, not the 32-bit ISA).
- some MAINTAINERS cleanups.
- the addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's
always present.
I've given these a simple build+boot test"

When I was adding a MAINTAINERS entry for SiFive's drivers I realized
that Albert's email is out of date -- he's gone back to Berkeley, so his
SiFive email is technically defunct. This patch updates his entry to a
current email address, hosted at Berkeley.

There aren't actually any files in the tree that match these patterns
right now, but we've just started submitting our drivers so I thought it
would be good to make sure there's at least someone at SiFive who's
listed as maintaining them. I'm leaving the RISC-V lists on here
because:
* As of today, all the RISC-V ASICs that people can actually buy are
from SiFive -- though hopefully there'll be more soon!
* The RTL for many of our devices is open source, so I anticipate these
devices might make they way chips from other vendors.
* We may standardize some of these devices as part of a RISC-V
specification at some point in the future.
I'm a bit swamped right now so I might not be the most active maintainer
of these drivers, but I think it'd be good to make sure someone who has
hardware access gets CC'd on updates to our drivers just as a sanity
check. Hopefully that's an OK way to handle this.

Native PCI drivers for root complex devices were originally all in
drivers/pci/host/. Some of these devices can also be operated in endpoint
mode. Drivers for endpoint mode didn't seem to fit in the "host"
directory, so we put both the root complex and endpoint drivers in
per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc.
These per-device directories contain trivial Kconfig and Makefiles and
clutter drivers/pci/. Make a new drivers/pci/controllers/ directory and
collect all the device-specific drivers there.
No functional change intended.

Pull ARM SoC late updates from Olof Johansson:
"This is a branch with a few merge requests that either came in late,
or took a while longer for us to review and merge than usual and thus
cut it a bit close to the merge window. We stage them in a separate
branch and if things look good, we still send them up -- and that's
the case here.
This is mostly DT additions for Renesas platforms, adding IP block
descriptions for existing and new SoCs.
There are also some driver updates for Qualcomm platforms for SMEM/QMI
and GENI, which is their generalized serial protocol interface"

Pull ARM SoC platform updates from Olof Johansson:
"Here are the main updates for SoC support (besides DT additions) for
ARM 32- and 64-bit platforms. The branch also contains defconfig
updates to turn on drivers and options as needed on the various
platforms.
The largest parts of the delta are from cleanups moving platform data
and board file setup of TI platforms to ti-sysc bus drivers. There are
also some sweeping changes of eeprom and nand setup on Davinci, i.MX
and other platforms.
Samsung is removing support for Exynos5440, which was an oddball SoC
that hasn't been seen much use in designs.
Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D).
Linus Walleij is also removing support for ux500 (Sony Ericsson)
U8540/9540 SoCs that never made it to significant mass production and
products"

For the same reasons we've added dri-devel for all fbdev patches: Most
of the actively developed drivers using this infrastructure are in
drivers/gpu/. It just makes sense to cross-post patches and keep
aligned. And total activity in the backlight subsystem is miniscule
compared to drm overall.

Pull restartable sequence support from Thomas Gleixner:
"The restartable sequences syscall (finally):
After a lot of back and forth discussion and massive delays caused by
the speculative distraction of maintainers, the core set of
restartable sequences has finally reached a consensus.
It comes with the basic non disputed core implementation along with
support for arm, powerpc and x86 and a full set of selftests
It was exposed to linux-next earlier this week, so it does not fully
comply with the merge window requirements, but there is really no
point to drag it out for yet another cycle"

Expose a new system call allowing each thread to register one userspace
memory area to be used as an ABI between kernel and user-space for two
purposes: user-space restartable sequences and quick access to read the
current CPU number value from user-space.
* Restartable sequences (per-cpu atomics)
Restartables sequences allow user-space to perform update operations on
per-cpu data without requiring heavy-weight atomic operations.
The restartable critical sections (percpu atomics) work has been started
by Paul Turner and Andrew Hunter. It lets the kernel handle restart of
critical sections. [1] [2] The re-implementation proposed here brings a
few simplifications to the ABI which facilitates porting to other
architectures and speeds up the user-space fast path.
Here are benchmarks of various rseq use-cases.
Test hardware:
arm32: ARMv7 Processor rev 4 (v7l) "Cubietruck", 2-core
x86-64: Intel E5-2630 v3@2.40GHz, 16-core, hyperthreading
The following benchmarks were all performed on a single thread.
* Per-CPU statistic counter increment
getcpu+atomic (ns/op) rseq (ns/op) speedup
arm32: 344.0 31.4 11.0
x86-64: 15.3 2.0 7.7
* LTTng-UST: write event 32-bit header, 32-bit payload into tracer
per-cpu buffer
getcpu+atomic (ns/op) rseq (ns/op) speedup
arm32: 2502.0 2250.0 1.1
x86-64: 117.4 98.0 1.2
* liburcu percpu: lock-unlock pair, dereference, read/compare word
getcpu+atomic (ns/op) rseq (ns/op) speedup
arm32: 751.0 128.5 5.8
x86-64: 53.4 28.6 1.9
* jemalloc memory allocator adapted to use rseq
Using rseq with per-cpu memory pools in jemalloc at Facebook (based on
rseq 2016 implementation):
The production workload response-time has 1-2% gain avg. latency, and
the P99 overall latency drops by 2-3%.
* Reading the current CPU number
Speeding up reading the current CPU number on which the caller thread is
running is done by keeping the current CPU number up do date within the
cpu_id field of the memory area registered by the thread. This is done
by making scheduler preemption set the TIF_NOTIFY_RESUME flag on the
current thread. Upon return to user-space, a notify-resume handler
updates the current CPU value within the registered user-space memory
area. User-space can then read the current CPU number directly from
memory.
Keeping the current cpu id in a memory area shared between kernel and
user-space is an improvement over current mechanisms available to read
the current CPU number, which has the following benefits over
alternative approaches:
- 35x speedup on ARM vs system call through glibc
- 20x speedup on x86 compared to calling glibc, which calls vdso
executing a "lsl" instruction,
- 14x speedup on x86 compared to inlined "lsl" instruction,
- Unlike vdso approaches, this cpu_id value can be read from an inline
assembly, which makes it a useful building block for restartable
sequences.
- The approach of reading the cpu id through memory mapping shared
between kernel and user-space is portable (e.g. ARM), which is not the
case for the lsl-based x86 vdso.
On x86, yet another possible approach would be to use the gs segment
selector to point to user-space per-cpu data. This approach performs
similarly to the cpu id cache, but it has two disadvantages: it is
not portable, and it is incompatible with existing applications already
using the gs segment selector for other purposes.
Benchmarking various approaches for reading the current CPU number:
ARMv7 Processor rev 4 (v7l)
Machine model: Cubietruck
- Baseline (empty loop): 8.4 ns
- Read CPU from rseq cpu_id: 16.7 ns
- Read CPU from rseq cpu_id (lazy register): 19.8 ns
- glibc 2.19-0ubuntu6.6 getcpu: 301.8 ns
- getcpu system call: 234.9 ns
x86-64 Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz:
- Baseline (empty loop): 0.8 ns
- Read CPU from rseq cpu_id: 0.8 ns
- Read CPU from rseq cpu_id (lazy register): 0.8 ns
- Read using gs segment selector: 0.8 ns
- "lsl" inline assembly: 13.0 ns
- glibc 2.19-0ubuntu6 getcpu: 16.6 ns
- getcpu system call: 53.9 ns
- Speed (benchmark taken on v8 of patchset)
Running 10 runs of hackbench -l 100000 seems to indicate, contrary to
expectations, that enabling CONFIG_RSEQ slightly accelerates the
scheduler:
Configuration: 2 sockets * 8-core Intel(R) Xeon(R) CPU E5-2630 v3 @
2.40GHz (directly on hardware, hyperthreading disabled in BIOS, energy
saving disabled in BIOS, turboboost disabled in BIOS, cpuidle.off=1
kernel parameter), with a Linux v4.6 defconfig+localyesconfig,
restartable sequences series applied.
* CONFIG_RSEQ=n
avg.: 41.37 s
std.dev.: 0.36 s
* CONFIG_RSEQ=y
avg.: 40.46 s
std.dev.: 0.33 s
- Size
On x86-64, between CONFIG_RSEQ=n/y, the text size increase of vmlinux is
567 bytes, and the data size increase of vmlinux is 5696 bytes.

Pull clk updates from Stephen Boyd:
"This time we have a good set of changes to the core framework that do
some general cleanups, but nothing too major. The majority of the diff
goes to two SoCs, Actions Semi and Qualcomm. A brand new driver is
introduced for Actions Semi so it takes up some lines to add all the
different types, and the Qualcomm diff is there because we add support
for two SoCs and it's quite a bit of data.
Otherwise the big driver updates are on TI Davinci and Amlogic
platforms. And then the long tail of driver updates for various fixes
and stuff follows after that.

The use of of_clk_get_parent_{count,name}() and of_clk_init() is not
limited to clock providers.
Hence move these helpers into their own header file, so callers that are
not clock providers no longer have to include <linux/clk-provider.h>.

Pull staging/IIO updates from Greg KH:
"Here is the big staging and IIO driver update for 4.18-rc1.
It was delayed as I wanted to make sure the final driver deletions did
not cause any major merge issues, and all now looks good.
There are a lot of patches here, just over 1000. The diffstat summary
shows the major changes here:
1007 files changed, 16828 insertions(+), 227770 deletions(-)
Because of this, we might be close to shrinking the overall kernel
source code size for two releases in a row.
There was loads of work in this release cycle, primarily:
- tons of ks7010 driver cleanups
- lots of mt7621 driver fixes and cleanups
- most driver cleanups
- wilc1000 fixes and cleanups
- lots and lots of IIO driver cleanups and new additions
- debugfs cleanups for all staging drivers
- lots of other staging driver cleanups and fixes, the shortlog has
the full details.
but the big user-visable things here are the removal of 3 chunks of
code:
- ncpfs and ipx were removed on schedule, no one has cared about this
code since it moved to staging last year, and if it needs to come
back, it can be reverted.
- lustre file system is removed.
I've ranted at the lustre developers about once a year for the past
5 years, with no real forward progress at all to clean things up
and get the code into the "real" part of the kernel.
Given that the lustre developers continue to work on an external
tree and try to port those changes to the in-kernel tree every once
in a while, this whole thing really really is not working out at
all. So I'm deleting it so that the developers can spend the time
working in their out-of-tree location and get things cleaned up
properly to get merged into the tree correctly at a later date.
Because of these file removals, you will have merge issues on some of
these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
atomisp driver). Just delete those files, it's a simple merge :)
All of this has been in linux-next for a while with no reported
problems"

The Lustre filesystem has been in the kernel tree for over 5 years now.
While it has been an endless source of enjoyment for new kernel
developers learning how to do basic codingstyle cleanups, as well as an
semi-entertaining source of bewilderment from the vfs developers any
time they have looked into the codebase to try to figure out how to port
their latest api changes to this filesystem, it has not really moved
forward into the "this is in shape to get out of staging" despite many
half-completed attempts.
And getting code out of staging is the main goal of that portion of the
kernel tree. Code should not stagnate and it feels like having this
code in staging is only causing the development cycle of the filesystem
to take longer than it should. There is a whole separate out-of-tree
copy of this codebase where the developers work on it, and then random
changes are thrown over the wall at staging at some later point in time.
This dual-tree development model has never worked, and the state of this
codebase is proof of that.
So, let's just delete the whole mess. Now the lustre developers can go
off and work in their out-of-tree codebase and not have to worry about
providing valid changelog entries and breaking their patches up into
logical pieces. They can take the time they have spend doing those
types of housekeeping chores and get the codebase into a much better
shape, and it can be submitted for inclusion into the real part of the
kernel tree when ready.

1st round of IIO new device support, features and cleanup for the 4.18 cycle
A nice mix this time of excellent cleanups (many to send drivers
speeding toward staging graduations) and new drivers / device support.
A good part of this is Brian Masney's never ending task on the tsl2x7x
driver. The end is in sight so hopefully we'll get that one out of
staging very soon!
New device support
* AD5686
- Support AD5685R (was wrongly present as AD5685)
- Support AD5672R, AD5676, AD5676, AD5684R and AD5686R 4 and 8 channel
SPI DACs with various precisions.
- Support AD5671R, AD5675R, AD5694, AD5694R, AD5695R, AD5696 and AD5696R
I2C DACs with various percisions and numbers of channels.
* Analog front end rescale driver - New driver.
- Support current sensing usings a shunt resistor.
- Support simple voltage dividers.
- support simple current sense amplifiers.
* TI dac5571
- New driver and device bindings supporting:
dac5571, dac6571, dac7571, dac5574, dac6574, dac7574,
dac5573, dac6573 and dac7573
* Meson-adc
- Support for Meson AXG with DT bindings.
* mpu6050
- Support the mpu9255 which only requires additional WHOAMI entry and
compatible string.
* st_lsm6dsx
- Support for lsm330dlc combinded accelerometer and gyro sensors with
DT bindings.
* stm32_adc
- Add support for STM32MP1 with bindings.
Staging graduations
* adis16201 after some excelent cleanup by Himanshu Jha.
* adis16029 after some excelent cleanup by Shreeya Patel.
New features:
* ABI docs
- Add core ABI docs for angle channels.
* inv_mpu6050
- Provide support for the full range of interrupts the device
supports.
* st_accel
- Add SMO8840 ACPI ID seen in the wild on some Lenovo machines.
* stx104
- Provide a multiple gpio get function.
Cleanups / Minor fixes
* core
- Use new nested structure support to improve kernel-doc.
* ad2s1200
- Use be16_to_cpup instead of opencoding.
* ad5686
- Indentation tidy up.
- Switch to SPDX
- Refactor to allow various numbers of channels.
- Refactor to separate core and SPI specific support, prior to
addition of i2c equivalent devices.
* ad7606
- Use drvdata directly from device rather than boucing via the
platform_device structure.
* ad7746
- Replace opencoded byte swapped i2c calls with _swapped variants.
- White space and line break readability improvements.
- Reorder includes and variable declarations where appropriate.
* ad7791
- Changes to the AD ADC library used by this driver took in the
sampling frequency. This lead to be the wrong path being the one
tied to the resulting attribute, so it didn't work, and a warning
to be printed.
* ad7780
- Remove apparent support for sampling frequency control on devices
that don't support changing the sampling attributes.
* ade7854
- Fix a read of the wrong number of bits.
- Improve error handling on i2c read/write errors.
- Rework i2c and spi code to reduce duplication.
* adis16201 (staging)
- Improve meaning inherent in some macro names by adding units etc
where relevant.
- Adjust comments to improve detail and drop the irrelevant.
- Rename register address definitions definitions to add a _REG
postfix, clearly separating them from field definitions. Reorganize
the definitions to group register address and fields.
- Use sign_extend32 rather than open coding.
- Reverse Xmas tree ordering where appropriate and align function args.
- Remove unused headers.
- Use GENMASK where appropriate instead of open coding.
* adis16209 (staging)
- Indent field definitions to visually separate them from
register address definitions.
- Use reverse xmas tree ordering where appropriate.
- Add some whitespace where it will help readability.
- Drop some unused headers.
- Use GENMASK where appropriate.
* ad2s1200
- Drop unnecessary includes and reorder alphabetically.
- Reverse xmas tree and blank line cleanups.
* atlas-ph-sensor
- Use msleep instead of usleep_range where the precise value doesn't
matter and the delays are long.
* bcm150
- Drop transaction splitting as core now handles it.
* cros_ec
- Move the shared header to the include/iio/common directory.
This brings it inline with the other multiple type devices.
- Use drvdata directly from device rather than boucing via the
platform_device structure.
* hid-sensors
- Use drvdata directly from device rather than boucing via the
platform_device structure.
* inv_mpu6050
- Clear out a second function definition for the same function.
- Don't flush fifo when the iio buffer is full but just drop excess
data.
- Tidy up set_power_itg and ensure it is used in the right places.
- Use set_power_itg rather than opencoding it again in the i2c mux
control.
- Make sure error paths disable the power if undoing power on.
- Used managed devm_ functions during probe. Delete remove function.
- Refactor to pull raw data read out of read_raw function.
- Simplify data reading error paths.
- Only enable the i2c mux for chips with the i2c aux bus (not icm20608)
- Fix a potential deadlock due to varying lock ordering.
- Fix an issue where first sample from gyro after enabling is unstable
by dropping the first sample.
- Fix an issue where the user_ctrl register is incorrectly overwritten.
- Tidy up some grammar and spelling minor issus.
* mcp320x
- Use vendor compatible strings.
* mcp4018
- Switch to using i2c .probe_new.
* mcp4351
- switch to using i2c .probe_new.
* meson-adc
- rework handing on common ADC platform data so it can be shared
across multiple families of SoCs.
* sca3000
- Fix an error handling path if the ring configure fails.
* st_lsm6dsx
- Fix a wrong fifo threshold mask (no actual effect)
* stm32-dfsdm
- Style fixes and cleanups.
- Check filter ID is in range and check spi-max-frequency.
* tsl2x7x (staging)
- Drop some unnecessary function calls, unused variables and
unnecessary local variables.
- Fix wrong interrupt type.
- Avoid unnecessary double clear of interrupt.
- Simplify proximity calibration call which did various things
unrelated to actually calibrating.
- Separate control of the proximity and ALS interrupts.
- Improve consistency of logging.
- Separate ALS and proximity persistence settings as they have
separate hardware controls.
- Tidy up variable ordering.
- Add Brian to copyright notice given consider work on this driver.
- Take advantage of hardware support for I2C address auto increment.
- Combine individuaal enable and period attributes for the two
directions on the threshold events into a single value as the
hardware doesn't separate them.
- Move integration_time* attributes from light channel to
intensity value as they effect the intensity readings directly
and the light reading only indirectly. Hence this better
reflects reality. Also move the calibscale_available.
- Avoid returning an error in the IRQ handler.
- Hard code the reg value in _clear_interrupts as it only takes
one value in the code. Result is the function has little
purpose so opencode the two remaining i2c_smbus_write_byte
calls.
- Drop some unnecessary checking of the chip status register.
- Tidy up return path in _write_interrupt_config.
- Tidy up the ID verification code.
- Move the power and diode settings defines into the header as these
are needed for platform data configuration.
- Various renames and comment cleanups for consistency and clarity.
- Use actual device defaults for default startup settings.
- SPDX
- Add some range sanity checking to sysfs attribute writes.
- Don't provide event interfaces if the interrupt line isn't available.
- Use IIO_CONST_ATTR macro for calibscale_available as it's a constant
string.
- Fix the integration time and lux equations.
- Make device IDs explicit index values in the device_channel_config array.

If an ADC channel measures the midpoint of a voltage divider, the
interesting voltage is often the voltage over the full resistance.
E.g. if the full voltage is too big for the ADC to handle.
Likewise, if an ADC channel measures the voltage across a shunt
resistor, with or without amplification, the interesting value is
often the current through the resistor.
This driver solves these problems by allowing to linearly scale a channel
and/or by allowing changes to the type of the channel.

Similar to current sense shunts, but an amplifier enables the use
of a smaller sense resistance.

An ADC is often used to measure other quantities indirectly. This
binding describe one cases, a "big" voltage measured with the help
of a voltage divider.

The AD5694/AD5694R/AD5695R/AD5696/AD5696R are a family of 4 channel DACs
with 12-bit, 14-bit and 16-bit precision respectively. The devices have
either no built-in reference, or built-in 2.5V reference.
The AD5671R/AD5675R are similar, except that they have 8 instead of 4
channels.
These devices are similar to AD5672R/AD5676/AD5676R and
AD5684/AD5684R/AD5684/AD5685R/AD5686/AD5686R, except that they use i2c
instead of spi.
