Pull thermal control updates from Rafael Wysocki:
"As far as new functionality is concerned, there is a new thermal
driver for the Intel Hardware Feedback Interface (HFI) along with some
intel-speed-select utility changes to support it. There are also new
DT compatible strings for a couple of platforms, and thermal zones on
some platforms will be registered as HWmon sensors now.
Apart from the above, some drivers are updated (fixes mostly) and
there is a new piece of documentation for the Intel DPTF (Dynamic
Power and Thermal Framework) sysfs interface.
Specifics:
- Add a new thermal driver for the Intel Hardware Feedback Interface
(HFI) including the HFI initialization, HFI notification interrupt
handling and sending CPU capabilities change messages to user space
via the thermal netlink interface (Ricardo Neri, Srinivas
Pandruvada, Nathan Chancellor, Randy Dunlap).
- Extend the intel-speed-select utility to handle out-of-band CPU
configuration changes and add support for the CPU capabilities
change messages sent over the thermal netlink interface by the new
HFI thermal driver to it (Srinivas Pandruvada).
- Convert the DT bindings to yaml format for the Exynos platform and
fix and update the MAINTAINERS file for this driver (Krzysztof
Kozlowski).
- Register the thermal zones as HWmon sensors for the QCom's Tsens
driver and TI thermal platforms (Dmitry Baryshkov, Romain Naour).
- Add the msm8953 compatible documentation in the bindings (Luca
Weiss).
- Add the sm8150 platform support to the QCom LMh driver's DT binding
(Thara Gopinath).
- Check the command result from the IPC command to the BPMP in the
Tegra driver (Mikko Perttunen).
- Silence the error for normal configuration where the interrupt is
optionnal in the Broadcom thermal driver (Florian Fainelli).
- Remove remaining dead code from the TI thermal driver (Yue
Haibing).
- Don't use bitmap_weight() in end_power_clamp() in the powerclamp
driver (Yury Norov).
- Update the OS policy capabilities handshake in the int340x thermal
driver (Srinivas Pandruvada).
- Increase the policies bitmap size in int340x (Srinivas Pandruvada).
- Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
int340x thermal driver (Rafael Wysocki).
- Check for NULL after calling kmemdup() in int340x (Jiasheng Jiang).
- Add Intel Dynamic Power and Thermal Framework (DPTF) kernel
interface documentation (Srinivas Pandruvada).

"These are mostly fixes and cleanups all over the code and a new piece
of documentation for Intel uncore frequency scaling.
Functionality-wise, the intel_idle driver will support Sapphire Rapids
Xeons natively now (with some extra facilities for controlling
C-states more precisely on those systems), virtual guests will take
the ACPI S4 hardware signature into account by default, the
intel_pstate driver will take the defualt EPP value from the firmware,
cpupower utility will support the AMD P-state driver added in the
previous cycle, and there is a new tracer utility for that driver.

obtain CPU capacity.
There are also a few new quirks, a bunch of fixes, including the
platform-level _OSC handling change to make it actually take the
platform firmware response into account, some code and documentation
cleanups, and a notable update of the ACPI device enumeration
documentation.

Pull RCU updates from Paul McKenney:
- Fix idle detection (Neeraj Upadhyay) and missing access marking
detected by KCSAN.
- Reduce coupling between rcu_barrier() and CPU-hotplug operations, so
that rcu_barrier() no longer needs to do cpus_read_lock(). This may
also someday allow system boot to bring CPUs online concurrently.

excessive lock contention due to workloads placing heavy update-side
stress on RCU tasks.
- Improvements to RCU priority boosting, including changes from Neeraj
Upadhyay, Zqiang, and Alison Chaiken.

Move compound_pincount from the third page to the second page, which
means it's available for all compound pages. That lets us delete
hpage_pincount_available().
On 32-bit systems, there isn't enough space for both compound_pincount
and compound_nr in the second page (it would collide with page->private,
which is in use for pages in the swap cache), so revert the optimisation
of storing both compound_order and compound_nr on 32-bit systems.

ASoC: Updates for v5.18
Quite a quiet release for ASoC, lots of work on drivers and platforms
but nothing too groundbreaking but not much on the core itself:
- Start of moving SoF to support multiple IPC mechanisms.
- Use of NHLT ACPI table to reduce the amount of quirking required for
Intel systems.
- Some building blocks for use in forthcoming Intel AVS driver for
legacy Intel DSP firmwares.
- Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with
TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek
MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas

KVM_CAP_DISABLE_QUIRKS is irrevocably broken. The capability does not
advertise the set of quirks which may be disabled to userspace, so it is
impossible to predict the behavior of KVM. Worse yet,
KVM_CAP_DISABLE_QUIRKS will tolerate any value for cap->args[0], meaning
it fails to reject attempts to set invalid quirk bits.
The only valid workaround for the quirky quirks API is to add a new CAP.
Actually advertise the set of quirks that can be disabled to userspace
so it can predict KVM's behavior. Reject values for cap->args[0] that
contain invalid bits.
Finally, add documentation for the new capability and describe the
existing quirks.

'virtio,mmio' devices are always coherent within a guest. As Arm DTs
are default non-coherent, the 'dma-coherent' property needs to be set on
the virtio device to mark them as such. This aligns with the QEMU 'virt'
machine DTB.

The CSR GSD4t is a CSR product using the SiRFstarIV core, and
the CSR CSRG05TA03-ICJE-R is a CSR product using the SiRFstarV
core.
These chips have a SRESETN line that can be pulled low to hard
reset the chip and in some designs this is connected to a GPIO,
so add this as an optional property.
Update the example with a reset line so users see that it need
to be tagged as active low.

Most NVMEM providers have cells at hardcoded addresses however there are
some exceptions. Some devices store cells layout in internal structs
using custom formats.
It's important to allow NVMEM consumers to still reference such NVMEM
cells. Making "reg" optional allows defining NVMEM cells by their names
only and using them with phandles.

First set of new device support, fixes, cleanups and features for IIO in 5.18
This cycle we had quite a few series that applied similar changes
to lots of drivers. To keep this description manageable I have
called those out in their own section rather than per driver.
Particularly pleased to see the long running AFE precision series
going in this cycle.
Series includes some late breaking fixes.
New device support
* adi,ada4250 amplifier
- New driver and dt bindings for this programmable gain amplifier.
* adi,admv1014 microwave down-converter
- New driver, dt bindings and some device specific ABI that
may be generalized as more drivers for devices similar to this
are added.
* adi,admv4420 K Band down-converter.
- New driver and dt bindings.
* adi,adxl367 accelerometer driver.
- New driver, dt-bindings + some new IIO ABI definitions to support
reference magnitude events where an estimate of the acceleration
due to gravity has been removed.
- A few fixes as follow up patches.
* adi,ltc2688 DAC with toggle and dither modes.
- New driver and bindings. Includes some new driver specific (for now)
ABI for handling toggle mode and the addition of a dither waveform to
the DAC output.
* AFE (analog front end) add support for additional types of analog device
in front of an ADC.
- RTD temperature sensors with dt bindings.
- Temperature transducers wit dt bindings.
- Related cleanup and features listed in other sections below.
* maxim,ds3502 potentiometer.
- Add support to ds1803 driver which required significant rework.
* mediatek,mt2701-auxadc driver
- Add mediatek,mt8186-auxadc - id table and chip specific info only.
* semtech,sx9324, semtech,ax9360
- Substantial refactoring of sx9310 to extract core logic for reuse
into a separate module
- New driver using this supporting sx9324 proximity sensors.
- New driver using this supporting sx9360 proximity sensors.
* silan,sc7a20
- Compatible with the st,lis2dh (or nearly anyway) so add ID and
chip specific info to enable support. Also silan vendor ID added
for dt-bindings.
Staging graduation
* adi,ad7280a monitoring ADC for stacked lithium-ion batteries in
electric cars and similar.
- Substantial rework of driver required to bring inline with current
IIO best practice. An unusual device in IIO so some interesting features
we may see more of in future.
Multiple driver/core cleanup
- Use sysfs_emit() in simple locations where there is no path to change
to various core created attributes.
- Trivial white space fixes around inconsistency between space after { and
before } in id tables.
- Introduce new handling for fractional types to avoid repeated similar
implementations. Use this in 3 drivers. Note this is also targeted
at future use in the AFE driver and was motivated by discussions
around the precision related work on that driver.
- of related header cleanups - drop of*.h and add mod_devicetable.h as
appropriate.
- Move a number of symbol exports into IIO_* namespaces. Two categories,
1) Library used by multiple drivers e.g. st_sensors
2) Core driver module exporting functions used by bus specific modules.
A few related cleanups in this set.
- Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and
similar to simplify drivers and take advantage of these new macros
allowing the compiler to do the job or removing unused code without
the need for __maybe_unused markings. Conversion of other drivers to
these new macros ongoing.
Features
* adi,adf4350
- Switch from of specific to generic device properties enabling use with
other firmware types.
* adi,adx345
- Switch from of specific to generic device properties.
- Add ACPI ID ADS0345
- Related driver cleanup.
* adi,hmc425a
- Switch from of specific to generic device properties.
* afe analog rescaler driver
- Wider range of types supported for scale.
- Support offset.
- Kunit tests.
* atlas,ezo-sensor
- Convert from of to device properties.
* fsl,mma8452
- Support mount matrix.
* infineon,dps310:
- Add ACPI ID IFX3100.
* invensense,mpu6050
- Convert to generic device properties.
* maxim,ds1803
- Add out_raw_available before supporting more devices.
- Convert from of specific to device properties.
* samsung,ssp_sensors
- Convert from of specific to device properties.
* st,stm32-timer trigger
- Convert from of specific to device properties.
* ti,hdc101x
- Add ACPI ID TXNW1010.
* ti,tsc2046:
- Add read_raw support to enable use of iio_hwmon and similar.
Fixes / cleanup.
* mailmap
- Update for Cai Huoqing
* MAINTAINERS
- Fix Analog Devices related links.
- Add entry for ADRF6780
- Add entry for ADMV1013
- Add entry for AD7293
- Add entry for ADMV8818
- Update files listed for adis-lib
* iio core:
- Fix wrong comment about current_mode being something a driver should
ever access.
- Use struct_size() rather than open coding in industrialio-hw-consumer
* adi,axl355
- Use units.h definitions instead of local versions.
* adi,adis-lib
- Simplify *updated_bits() macro
- Whitespace cleanup.
* afe - Note many of these fixes only apply to particular configurations
so the problems have probably not been seen in the wild, but will be
visible with new usecases enabled this cycle.
- Fix application of consumer scale for IIO_VAL_INT.
- Apply a scale of 1 when no scale is provided.
- Make best effort to establish a valid offset value for fractional
cases.
- Use s64 for scale calculations where parameters may be signed.
- Tidy up include order.
- Improve accuracy for small fractional sales
- Reduce risk of integer overflow.
* ams,as3935
- Use devm_delayed_work_autocancel() to replace open coded equivalent.
* aspeed,adc
- Fix wrong use of divider flag.
* atmel,sama5d2-adc
- Relax atmel,trigger-edge-type to optional.
- Drop Ludovic Desroches from listed maintainers of the dt-binding
inline with previous MAINTAINERS entry update.
* fsl,mma8452
- Fix probing when i2c_device_id used.
- dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev.
Use dev_to_iio_dev() instead. Note the original path in here
worked more by luck than design.
* invensense,mpu6050
- Drop ACPI_PTR() protection to avoid an unused warning.
- Use fact ACPI_COMPANION() returns null when ACPI_HANDLE() does to
simplify handling.
* motorola,cpcap-adc
- Drop unused assignment.
* qcom,spmi-adc
- Fix wrong example of 'reg' in binding document.
* renesas,rzg2l-adc
- Trivial typo fix.
* semtech,sx9360
- Fix wrong register handling for event generation.
* st_sensors
- Allow manual disabling of I2C or SPI module if not needed for a particular
board. Default is still to enable the bus specific module if
appropriate bus is supported.
* st,lsm6dsx
- dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev.
Use dev_to_iio_dev() instead.
* ti,palmas-gpadc
- Split the interrupt fields in the dt-binding example
* ti,tsc2046
- Rework state machine to improve readability after recent debugging of
an issue fixed elsewhere.
- Add a sanity check to avoid very large memory allocations if a crazy
delay is specified.
* ti,twl6030
- Add error handling if devm_request_threaded_irq() fails.
* xilinx,ams
- Use devm_delayed_work_autocancel() instead of open coding equivalent.
- Fix missing required clock entry in dt-binding.
- Fix miss counting of channels resulting in ps channels not
being enabled.
- Fix incorrect values written to sequencer registers.
- Fix sequence for single channel reading.

Certificate based authentication is available as an alternative to
password based authentication.
The WMI commands are cryptographically signed using a separate
signing server and will be verified by the BIOS before being
accepted.
This commit details the fields that are needed to support that
implementation. At present the changes are intended for Lenovo
platforms, but have been designed to keep them as flexible as possible
for future implementations from other vendors.

Add a netfs_i_context struct that should be included in the network
filesystem's own inode struct wrapper, directly after the VFS's inode
struct, e.g.:
struct my_inode {
struct {
/* These must be contiguous */
struct inode vfs_inode;
struct netfs_i_context netfs_ctx;
};
};
The netfs_i_context struct so far contains a single field for the network
filesystem to use - the cache cookie:
struct netfs_i_context {
...
struct fscache_cookie *cache;
};
Three functions are provided to help with this:
(1) void netfs_i_context_init(struct inode *inode,
const struct netfs_request_ops *ops);
Initialise the netfs context and set the operations.
(2) struct netfs_i_context *netfs_i_context(struct inode *inode);
Find the netfs context from the VFS inode.
(3) struct inode *netfs_inode(struct netfs_i_context *ctx);
Find the VFS inode from the netfs context.
Changes
=======
ver #4)
- Fix netfs_is_cache_enabled() to check cookie->cache_priv to see if a
cache is present[3].
- Fix netfs_skip_folio_read() to zero out all of the page, not just some
of it[3].
ver #3)
- Split out the bit to move ceph cap-getting on readahead into
ceph_init_request()[1].
- Stick in a comment to the netfs inode structs indicating the contiguity
requirements[2].
ver #2)
- Adjust documentation to match.
- Use "#if IS_ENABLED()" in netfs_i_cookie(), not "#ifdef".
- Move the cap check from ceph_readahead() to ceph_init_request() to be
called from netfslib.
- Remove ceph_readahead() and use netfs_readahead() directly instead.

Rename netfs_read_*request to netfs_io_*request so that the same structures
can be used for the write helpers too.

Two labels used _ instead of - so were never found and one new PIX_FMT was
missing the label altogether. This led to these warnings:
