iio: add modifiers for linear acceleration
Add IIO_MOD_LINEAR_X, IIO_MOD_LINEAR_Y and IIO_MOD_LINEAR_Z modifiers to te
IIO core, which is preparatory for adding the Bosch BNO055 IMU driver.
Bosch BNO055 IMU can report raw accelerations (among x, y and z axis) as
well as the so called "linear accelerations" (again, among x, y and z axis)
which is basically the acceleration after subtracting gravity and for which
those new modifiers are for.

1st set of IIO new device support, features and cleanup for 6.1
This includes Nuno Sa's work to move the IIO core over to generic firmware
properties rather than having DT specific code paths. Combined with Andy
Shevchenko's long term work on drivers, this leaves IIO in a good state for
handling other firmware types.
New device support
- liteon,ltrf216a
* New driver and dt bindings to support this Light sensor.
- maxim,max11205
* New driver for this 16bit single channel ADC.
- memsensing,msa311
* New driver for this accelerometer. Includes a string helper for read/write.
- richtek,rtq6056
* New driver and dt binding to support this current monitor used to measure
power usage.
- yamaha,yas530
* Support the YAS537 variant (series includes several fixes for other parts
and new driver features).
Staging graduation
- adi,ad7746 CDC. Cleanup conducted against set of roadtest tests using
the posted RFC of that framework.
Features
- core
* Large rework to make all the core IIO code use generic firmware properties.
Includes switching some drivers over as well using newly provided
generic interfaces and allowing removal of DT specific ones.
* Support for gesture event types for single and double tap. Used in
bosch,bma400.
- atmel,at91-sama5d2
* Add support for temperature sensor which uses two muxed inputs to estimate
the temperature.
* Handle trackx bits of EMR register to improve temp sampling accuracy.
* Runtime PM support.
- liteon,ltrf216a
* Add a _raw channel output to allow working around an issue with
differing conversions equations that breaks some user space controls.
- mexelis,mlx90632
* Support regulator control.
- ti,tsc2046
* External reference voltage support.
Clean up and minor fixes
- Tree-wide
* devm_clk_get_enabled() replacements of opencoded equivalent.
* Remaining IIO_DMA_MINALIGN conversions (the staging/iio drivers).
* Various minor warning and similar cleanup such as missing static
markings.
* strlcpy() to strscpy() for cases where return value not checked.
* provide units.h entries for more HZ units and use them in drivers.
- dt-bindings cleanup
* Drop maintainers listss where the email address is bouncing.
* Switch spi devices over to using spi-peripheral.yaml
* Add some missing unevaluatedProperties / additionalProperties: false
entries.
- ABI docs
* Add some missing channel type specific sampling frequency entries.
* Add parameter names for callback parameters.
- MAINTAINERS
* Fix wrong ADI forum links.
- core
* lockdep class per device, to avoid an issue with nest when one IIO
device is the consumer of another.
* White space tweaks.
- asc,dlhl60d
* Use get_unaligned_be24 to avoid some unusual data manipulation and masking.
- atmel,at91-sama5d2
* Fix wrong max value.
* Improve error handling when measuring pressure and touch.
* Add locks to remove races on updating oversampling / sampling freq.
* Add missing calls in suspend and resume path to ensure state is correctly
brought up if buffered capture was in use when suspend happened.
* Error out of write_raw() callback if buffered capture enabled to avoid
unpredictable behavior.
* Handle different versions having different oversampling ratio support and
drop excess error checking.
* Cleanup magic value defines where the name is just the value and hence
hurts readability.
* Use read_avail() callback to provide info on possible oversampling ratios.
* Correctly handle variable bit depth when doing oversampling on different
supported parts. Also handle higher oversampling ratios.
- fsl,imx8qxp
* Don't ignore errors from regulator_get_voltage() so as to avoid some
very surprising scaling.
- invensense,icp10100
* Switch from UNIVERSAL to DEFINE_RUNTIME_DEV_PM_OPS. UNIVERSAL rarely made
sense and is now deprecated. In this driver we just avoid double disabling
in some paths.
- maxim,max1363
* Drop consumer channel map provision by platform data. There have been
better ways of doing this for years and there are no in tree users.
- microchip,mcp3911
* Update status to maintained.
- qcom,spmi-adc5
* Support measurement of LDO output voltage.
- qcom,spmi-adc
* Add missing channel available on SM6125 SoC.
- st,stmpe
* Drop requirement on node name in binding now that driver correctly
doesn't enforce it.
- stx104
* Move to more appropriate addac directory
- ti,am335x
* Document ti,am654-adc compatible already in use in tree.
- ti,hmc5843
* Move dev_pm_ops out of header and use new pm macros to handle export.
- yamaha,yas530
* Minor cleanups.

This harmless print provides a very easy way of knowing
if the modem is detected properly during probing.
Promote it to an informational print so no hassle is required
enabling kernel debugging info to obtain it.
The rationale here is that:
On a lot of low-storage embedded devices, extensive kernel
debugging info is not always present as this would
increase it's size to much causing partition size issues.

misc/xilinx_sdfec: Replace kmap() with kmap_local_page()
kmap() is being deprecated in favor of kmap_local_page().
There are two main problems with kmap(): (1) It comes with an overhead as
the mapping space is restricted and protected by a global lock for
synchronization and (2) it also requires global TLB invalidation when the
kmap’s pool wraps and it might block when the mapping space is fully
utilized until a slot becomes available.
With kmap_local_page() the mappings are per thread, CPU local, can take
page faults, and can be called from any context (including interrupts).
It is faster than kmap() in kernels with HIGHMEM enabled. Furthermore,
the tasks can be preempted and, when they are scheduled to run again, the
kernel virtual addresses are restored and still valid.
Since its use in xilinx_sdfec.c is safe, replace kmap()i / kunmap() with

Makefile.extrawarn: re-enable -Wformat for clang; take 2
-Wformat was recently re-enabled for builds with clang, then quickly
re-disabled, due to concerns stemming from the frequency of default
argument promotion related warning instances.
commit
258fafcd0683 ("Makefile.extrawarn: re-enable -Wformat for clang")
commit
21f9c8a13bb2 ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"")
ISO WG14 has ratified N2562 to address default argument promotion
explicitly for printf, as part of the upcoming ISO C2X standard.
The behavior of clang was changed in clang-16 to not warn for the cited
cases in all language modes.
Add a version check, so that users of clang-16 now get the full effect
of -Wformat. For older clang versions, re-enable flags under the
-Wformat group that way users still get some useful checks related to
format strings, without noisy default argument promotion warnings. I
intentionally omitted -Wformat-y2k and -Wformat-security from being
re-enabled, which are also part of -Wformat in clang-16.

mm: pagewalk: Fix race between unmap and page walker
The mmap lock protects the page walker from changes to the page tables
during the walk. However a read lock is insufficient to protect those
areas which don't have a VMA as munmap() detaches the VMAs before
downgrading to a read lock and actually tearing down PTEs/page tables.
For users of walk_page_range() the solution is to simply call pte_hole()
immediately without checking the actual page tables when a VMA is not
present. We now never call __walk_page_range() without a valid vma.
For walk_page_range_novma() the locking requirements are tightened to
require the mmap write lock to be taken, and then walking the pgd
directly with 'no_vma' set.
This in turn means that all page walkers either have a valid vma, or
it's that special 'novma' case for page table debugging. As a result,
all the odd '(!walk->vma && !walk->no_vma)' tests can be removed.
