Add support for manipulating the internal heater of sht4x devices.
Enabling the heater removes condensed water from the sensor surface
which disturbs the relative humidity measurements.
The heater can operate at three heating levels (20, 110 or 200
milliwatts). Also, two heating durations may be selected (0.1 or 1s).
Once the heating time elapses the heater is automatically switched off.
Changes since v3:
* struct sht4x_data: add heating_complete timestamp
* struct sht4x_data: add data_pending flag
* heater_enable_store: return -EINVAL if input != 1
* heater_enable_store: check for data->heating_complete and update it
* heater_enable_store: set data_pending flag after heating request
* sht4x_read_values: msleep if heating in progress
* sht4x_read_values: dont send measurement request if data_pending
* heater_enable attr: make it RW
* Documentation: update info about heater_enable attr
Changes since v2:
* heater_enable_store: remove unnecessary if
* Documentation: remove incorrect info about turning off the heater
* be more specific in the patch description
Changes since v1:
* explain the use case of the new attributes set
* heater_enable attr: make it write-only
* heater_enable_store: define cmd as u8 instead of u8*
* heater_enable_store: remove unreachable data path
* heater_enable_store: remove unnecessary lock
* heater_enable_store: call i2c_master_send only if status==true

INA260 is similar to other chips of the series, except it has an internal
shunt resistor. The calibration register is therefore not present. Also,
the current register address was changed, though that does not matter for
the driver since the shunt voltage register (which is now the current
register) value is already used to read the current.

If we add ``thp_anon=32,64K:always`` to the kernel command line, we
will see the following error:
[ 0.000000] huge_memory: thp_anon=32,64K:always: error parsing string, ignoring setting
This happens because the correct format isn't ``thp_anon=<size>,<size>[KMG]:<state>```,
as [KMG] must follow each number to especify its unit. So, the correct
format is ``thp_anon=<size>[KMG],<size>[KMG]:<state>```.
Therefore, adjust the documentation to reflect the correct format of the
parameter ``thp_anon=``.

During the switch to YNL, the command to list all endpoints has been
accidentally restricted to users with admin permissions.
It looks like there are no reasons to have this restriction which makes
it harder for a user to quickly check if the endpoint list has been
correctly populated by an automated tool. Best to go back to the
previous behaviour then.
mptcp_pm_gen.c has been modified using ynl-gen-c.py:

This is a false positive data race between a seqcount latch writer and a reader
accessing stale data. Since its introduction, KCSAN has never understood the
seqcount_latch interface (due to being unannotated).
Unlike the regular seqlock interface, the seqcount_latch interface for latch
writers never has had a well-defined critical section, making it difficult to
teach tooling where the critical section starts and ends.
Introduce an instrumentable (non-raw) seqcount_latch interface, with
which we can clearly denote writer critical sections. This both helps
readability and tooling like KCSAN to understand when the writer is done
updating all latch copies.

Where the last set of fixes was mostly drivers, this time the devicetree
changes all come at once, targeting mostly the Rockchips, Qualcomm and
NXP platforms.
The Qualcomm bugfixes target the Snapdragon X Elite laptops, specifically
problems with PCIe and NVMe support to improve reliability, and a boot
regresion on msm8939. Also for Snapdragon platforms, there are a number
of correctness changes in the several platform specific device drivers,
but none of these are as impactful.
On the NXP i.MX platform, the fixes are all for 64-bit i.MX8 variants,
correcting individual entries in the devicetree that were incorrect and
causing the media, video, mmc and spi drivers to misbehave in minor
ways.
The Arm SCMI firmware driver gets fixes for a use-after-free bug and
for correctly parsing firmware information.
On the RISC-V side, there are three minor devicetree fixes for starfive
and sophgo, again addressing only minor mistakes. One device driver
patch fixes a problem with spurious interrupt handling.

Support direct I/O atomic writes by producing a single bio with REQ_ATOMIC
flag set.
Initially FSes (XFS) should only support writing a single FS block
atomically.
As with any atomic write, we should produce a single bio which covers the
complete write length.

The ptrace documentation for GCS was written prior to the implementation of
clone3() when we still blocked enabling of GCS via ptrace. This restriction
was relaxed as part of implementing clone3() support since we implemented
support for the GCS not being managed by the kernel but the documentation
still mentions the restriction. Update the documentation to reflect what
was merged.
We have not yet merged clone3() itself but all the support other than in
clone() itself is there.

Pedro Falcato's optimization [1] for checking sealed VMAs, which replaces
the can_modify_mm() function with an in-loop check, necessitates an update

Furthermore, the document has received offline comments regarding the code

PCI Express Interface PMU includes various performance counters
to monitor the data that is transmitted over the PCIe link. The
counters track various inbound and outbound transactions which
includes separate counters for posted/non-posted/completion TLPs.
Also, inbound and outbound memory read requests along with their
latencies can also be monitored. Address Translation Services(ATS)events
such as ATS Translation, ATS Page Request, ATS Invalidation along with
their corresponding latencies are also supported.
The performance counters are 64 bits wide.
For instance,
perf stat -e ib_tlp_pr <workload>
tracks the inbound posted TLPs for the workload.

Most of the callers of wbc_account_cgroup_owner() are converting a folio
to page before calling the function. wbc_account_cgroup_owner() is
converting the page back to a folio to call mem_cgroup_css_from_folio().
Convert wbc_account_cgroup_owner() to take a folio instead of a page,
and convert all callers to pass a folio directly except f2fs.
Convert the page to folio for all the callers from f2fs as they were the
only callers calling wbc_account_cgroup_owner() with a page. As f2fs is
already in the process of converting to folios, these call sites might
also soon be calling wbc_account_cgroup_owner() with a folio directly in
the future.
No functional changes. Only compile tested.

During the discussion before supporting rust on riscv, it was decided
not to support gcc yet, due to differences in extension handling
compared to llvm (only the version of libclang matching the c compiler
is supported). Recently Jason Montleon reported [1] that building with
gcc caused build issues, due to unsupported arguments being passed to
libclang. After some discussion between myself and Miguel, it is better
to disable gcc + rust builds to match the original intent, and
subsequently support it when an appropriate set of extensions can be
deduced from the version of libclang.

The MediaTek DPI module is typically associated with one of the
following multimedia power domains:
- POWER_DOMAIN_DISPLAY
- POWER_DOMAIN_VDOSYS
- POWER_DOMAIN_MM
The specific power domain used varies depending on the SoC design.
These power domains are shared by multiple devices within the SoC.
In most cases, these power domains are enabled by other devices.
As a result, the DPI module of legacy SoCs often functions correctly
even without explicit configuration.
It is recommended to explicitly add the appropriate power domain
property to the DPI node in the device tree. Hence drop the
compatible checking for specific SoCs.

Applications using the passthrough interfaces for IO want to continue
seeing the disk stats. These requests had been fenced off from this
block layer feature. While the block layer doesn't necessarily know what
a passthrough command does, we do know the data size and direction,
which is enough to account for the command's stats.
Since tracking these has the potential to produce unexpected results,
the passthrough stats are locked behind a new queue flag that needs to
be enabled with the /sys/block/<dev>/queue/iostats_passthrough
attribute.

Document support for defining a partition table in the mmc-card node.
This is needed if the eMMC doesn't have a partition table written and
the bootloader of the device load data by using absolute offset of the
block device. This is common on embedded device that have eMMC installed
to save space and have non removable block devices.
If an OF partition table is detected, any partition table written in the
eMMC will be ignored and won't be parsed.
eMMC provide a generic disk for user data and if supported (JEDEC 4.4+)
also provide two additional disk ("boot1" and "boot2") for special usage
of boot operation where normally is stored the bootloader or boot info.
New JEDEC version also supports up to 4 GP partition for other usage
called "gp1", "gp2", "gp3", "gp4".

Commit 681ce86235 ("vfs: Delete the associated dentry when deleting a
file") introduced an unconditional deletion of the associated dentry when a
file is removed. However, this led to performance regressions in specific
benchmarks, such as ilebench.sum_operations/s [0], prompting a revert in
commit 4a4be1ad3a ("Revert "vfs: Delete the associated dentry when
deleting a file"").
This patch seeks to reintroduce the concept conditionally, where the
associated dentry is deleted only when the user explicitly opts for it
during file removal. A new sysctl fs.automated_deletion_of_dentry is
added for this purpose. Its default value is set to 0.
There are practical use cases for this proactive dentry reclamation.
Besides the Elasticsearch use case mentioned in commit 681ce86235,
additional examples have surfaced in our production environment. For
instance, in video rendering services that continuously generate temporary
files, upload them to persistent storage servers, and then delete them, a
large number of negative dentries—serving no useful purpose—accumulate.
Users in such cases would benefit from proactively reclaiming these
negative dentries.

Massage the documentation for KVM_X86_QUIRK_SLOT_ZAP_ALL to call out that
it applies to moved memslots as well as deleted memslots, to avoid KVM's
"fast zap" terminology (which has no meaning for userspace), and to reword
the documented targeted zap behavior to specifically say that KVM _may_
zap a subset of all SPTEs. As evidenced by the fix to zap non-leafs SPTEs
with gPTEs, formally documenting KVM's exact internal behavior is risky
and unnecessary.

The current policy management makes it impossible to use IPE
in a general purpose distribution. In such cases the users are not
building the kernel, the distribution is, and access to the private
key included in the trusted keyring is, for obvious reason, not
available.
This means that users have no way to enable IPE, since there will
be no built-in generic policy, and no access to the key to sign
updates validated by the trusted keyring.
Just as we do for dm-verity, kernel modules and more, allow the
secondary and platform keyrings to also validate policies. This
allows users enrolling their own keys in UEFI db or MOK to also
sign policies, and enroll them. This makes it sensible to enable
IPE in general purpose distributions, as it becomes usable by
any user wishing to do so. Keys in these keyrings can already
load kernels and kernel modules, so there is no security
downgrade.
Add a kconfig each, like dm-verity does, but default to enabled if
the dependencies are available.

Currently IPE accepts an update that has the same version as the policy
being updated, but it doesn't make it a no-op nor it checks that the
old and new policyes are the same. So it is possible to change the
content of a policy, without changing its version. This is very
confusing from userspace when managing policies.
Instead change the update logic to reject updates that have the same
version with ESTALE, as that is much clearer and intuitive behaviour.

Document that hypervisors must set HCR_EL2.MCE2 and handle MOPS
exceptions when they migrate a vCPU to another type of CPU, as Linux may
not be able to handle the exception at all times.
As one example, when running under nested virtualization, KVM does not
handle MOPS exceptions from the nVHE/hVHE EL2 hyp as the hyp is never
migrated, so the host hypervisor needs to handle them. There may be
other situations (now or in the future) where the kernel can't handle an
unexpected MOPS exception, so require that the hypervisor handles them.
