Pull power management updates from Rafael Wysocki:
"Once again, the changes are dominated by cpufreq updates, but this
time the majority of them are cpufreq core changes, mostly related to
the introduction of policy locking guards and __free() usage, and
fixes related to boost handling.
Still, there is also a significant update of the intel_pstate driver
making it register an energy model when running on a hybrid platform
which is used for enabling energy-aware scheduling (EAS) if the driver
operates in the passive mode (and schedutil is used as the cpufreq
governor for all CPUs which is the passive mode default).
There are some amd-pstate driver updates too, for a good measure,
including the "Requested CPU Min frequency" BIOS option support and
new online/offline callbacks.
In the cpuidle space, the most significant change is the addition of a
C1 demotion on/off sysfs knob to intel_idle which should help some
users to configure their systems more precisely. There is also the
conversion of the PSCI cpuidle driver to a faux device one and there
are two small updates of cpuidle governors.
Device power management is also modified quite a bit, especially the
handling of devices with asynchronous suspend and resume enabled
during system transitions. They are now going to be handled more
asynchronously during suspend transitions and somewhat less
aggressively during resume transitions.
Apart from the above, the operating performance points (OPP) library
is now going to use mutex locking guards and scope-based cleanup
helpers and there is the usual bunch of assorted fixes and code
cleanups.

Pull ACPI updates from Rafael Wysocki:
"The most significant part of these changes is an ACPICA update
covering two upstream ACPICA releases, 20241212 and 20250404, that
have not been included into the kernel code base yet.
Among other things, it adds definitions needed to address GCC 15's
-Wunterminated-string-initialization warnings, adds support for three
new tables (MRRM, ERDT, RIMT), extends support for two tables (RAS2,
DMAR), and fixes some issues.
On top of the above, there is a new parser for the MRRM table, more
changes related to GCC 15's -Wunterminated-string-initialization
warnings, a CPPC library update including functions related to
autonomous CPU performance state selection, a couple of new quirks,
some assorted fixes and some code cleanups.

spi: Updates for v6.16
This bulk of the changes in this release are driver work, as well as
new device support we have some important work on performance over
several drivers, and big overhauls for maintainability on a couple too.
Highlights include:
- Big cleanups of the sh-msiof driver from Geert Uytterhoeven, and of
the NXP FSPI driver from Haibo Chen.
- Performance improvements for the AXI SPI engine.
- Support for writes to memory mapped flashes on Renesas devices.
- Integrated DMA support for Tegra210 QSPI, used by the Tegra234.
- DMA support for Amlogic SPI controllers.
- Support for AMD HID2, Qualcomm IPQ5018, Renesas RZ/G3E, Rockchip
RK3528 and Samsung Exynos Autov920.
An update to fix some issues with the Atmel QSPI driver runtime PM
pulled in a new API from the PM core, and the Renesas memory mapped
write changes pull in some code that's shared in drivers/memory.

gpio updates for v6.16-rc1
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where applicable
which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which will
take off the burden from GPIO drivers of checking this down the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter callbacks
- convert more drivers to making the irq_chip immutable as is recommended
by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built with
COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that makes
the setup easier for user-space than the existing driver-level sysfs
attributes and also adds more advanced configuration features (such as
referring to aggregated lines by their original names or modifying
their names as exposed by the aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the global
GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600 (new
drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents
Misc:
- TODO list updates

Merge tag 'gpio-updates-for-v6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We have three new drivers, some refactoring in the GPIO core, lots of
various changes across many drivers, new configfs interface for the
virtual gpio-aggregator module and DT-bindings updates.
The treewide conversion of GPIO drivers to using the new value setter
callbacks is ongoing with another round of GPIO drivers updated. You
will also see these commits coming in from other subsystems as with
the relevant changes merged into mainline last cycle, I've started
converting GPIO providers located elsewhere than drivers/gpio/.
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where
applicable which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which
will take off the burden from GPIO drivers of checking this down
the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter
callbacks
- convert more drivers to making the irq_chip immutable as is
recommended by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built
with COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that
makes the setup easier for user-space than the existing
driver-level sysfs attributes and also adds more advanced
configuration features (such as referring to aggregated lines by
their original names or modifying their names as exposed by the
aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the
global GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600
(new drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents
Misc:
- TODO list updates"

sound updates for 6.16-rc1
We've received a lot of activities in this cycle, mostly about leaf
driver codes rather than the core part, but with a good mixture of
code cleanups and new driver additions. Below are some highlights:
* ASoC:
- Support for automatically enumerating DAIs from standards conforming
SoundWire SDCA devices; not much used as of this writing, rather for
future implementations
- Conversion of quite a few drivers to newer GPIO APIs
- Continued cleanups and helper usages in allover places
- Support for a wider range of Intel AVS platforms
- Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32
Everest Semiconductor ES8375 and ES8389, Longsoon-1 AC'97
controllers, nVidia Tegra264, Richtek ALC203 and RT9123 and Rockchip
SAI controllers
* HD-audio:
- Lots of cleanups of TAS2781 codec drivers
- A new HD-audio control bound via ACPI for Nvidia
- Support for Tegra264, Intel WCL, usual new codec quirks
* USB-audio:
- Fix a race at removal of MIDI device
- Pioneer DJM-V10 support, Scarlett2 driver cleanups
* Misc:
- Cleanups of deprecated PCI functions
- Removal of unused / dead function codes

Remove legacy 'cc-disable-warning' use from the generic build scripts
This just converts the 'cc-disable-warning' uses in the generic makefile extrawarn script to use the plain 'cc-option' form instead. Partly to clean things up, and partly just to have the new form get some proper test coverage. I'll leave the various random other uses of 'cc-disable-warning' alone and let subsystem maintainers decide if they want to convert to the new unified model.

selftests/bpf: Add tests with stack ptr register in conditional jmp
Add two tests:
- one test has 'rX <op> r10' where rX is not r10, and
- another test has 'rX <op> rY' where rX and rY are not r10
but there is an early insn 'rX = r10'.
Without previous verifier change, both tests will fail.

BUG regs 400
The main failure reason is due to r10 in precision backtracking bookkeeping.
Actually r10 is always precise and there is no need to add it for the precision
backtracking bookkeeping.
One way to fix the issue is to prevent bt_set_reg() if any src/dst reg is
r10. Andrii suggested to go with push_insn_history() approach to avoid
explicitly checking r10 in backtrack_insn().
This patch added push_insn_history() support for cond_jmp like 'rX <op> rY'
operations. In check_cond_jmp_op(), if any of rX or rY is a stack pointer,
push_insn_history() will record such information, and later backtrack_insn()
will do bt_set_reg() properly for those register(s).

drm/connector: only call HDMI audio helper plugged cb if non-null
On driver remove, sound/soc/codecs/hdmi-codec.c calls the plugged_cb
with NULL as the callback function and codec_dev, as seen in its
hdmi_remove function.
The HDMI audio helper then happily tries calling said null function
pointer, and produces an Oops as a result.
Fix this by only executing the callback if fn is non-null. This means
the .plugged_cb and .plugged_cb_dev members still get appropriately
cleared.

The issue is that cpus_read_lock() is taken within buffer->mutex. The
memory mapped pages are taken with the mmap_lock held. The buffer->mutex
is taken within the cpu_buffer->mapping_lock. There's quite a chain with
all these locks, where the deadlock can be fixed by moving the
cpus_read_lock() outside the taking of the buffer->mutex.

wifi: iwlwifi: mld: Work around Clang loop unrolling bug
The nested loop in iwl_mld_send_proto_offload() confuses Clang into
thinking there could be a final loop iteration past the end of the
"nsc" array (which is only 4 entries). The FORTIFY checking in memcmp()
(via ipv6_addr_cmp()) notices this (due to the available bytes in the
out-of-bounds position of &nsc[4] being 0), and errors out, failing
the build. For some reason (likely due to architectural loop unrolling
configurations), this is only exposed on ARM builds currently. Due to
Clang's lack of inline tracking[1], the warning is not very helpful:
include/linux/fortify-string.h:719:4: error: call to '__read_overflow' declared with 'error' attribute: detected read beyond size of object (1st parameter)
719 | __read_overflow();
| ^
1 error generated.
But this was tracked down to iwl_mld_send_proto_offload()'s
ipv6_addr_cmp() call.
An upstream Clang bug has been filed[2] to track this. For now fix the
build by explicitly bounding the inner loop by "n_nsc", which is what
"c" is already limited to.

Merge patch series "dropbehind fixes and cleanups"
Jens Axboe <axboe@kernel.dk> says: As per the thread here: https://lore.kernel.org/linux-fsdevel/20250525083209.GS2023217@ZenIV/ there was an issue with the dropbehind support, and hence it got reverted (effectively) for the 6.15 kernel release. The problem stems from the fact that the folio can get redirtied and/or scheduled for writeback after the initial dropbehind test, and before we have it locked again for invalidation. Patches 1+2 add a generic helper that both the read and write side can use, and which checks for !dirty && !writeback before going ahead with the invalidation. Patch 3 reverts the FOP_DONTCACHE disable, and patches 4 and 5 do a bit of cleanup work to further unify how the read and write side handling works. This can reasonably be considered a 2 part series, as 1-3 fix the issue and could go to stable, while 4-5 just cleanup the code. * patches from https://lore.kernel.org/20250527133255.452431-1-axboe@kernel.dk: mm/filemap: unify dropbehind flag testing and clearing mm/filemap: unify read/write dropbehind naming Revert "Disable FOP_DONTCACHE for now due to bugs" mm/filemap: use filemap_end_dropbehind() for read invalidation mm/filemap: gate dropbehind invalidate on folio !dirty && !writeback Link: https://lore.kernel.org/20250527133255.452431-1-axboe@kernel.dk Signed-off-by: Christian Brauner <brauner@kernel.org> |

mm/filemap: unify dropbehind flag testing and clearing
The read and write side does this a bit differently, unify it such that
the _{read,write} helpers check the bit before locking, and the generic
handler is in charge of clearing the bit and invalidating, once under
the folio lock.

A moderately busy cycle for documentation this time around:
- The most significant change is the replacement of the old kernel-doc
script (a monstrous collection of Perl regexes that predates the Git era)
with a Python reimplementation. That, too, is a horrifying collection of
regexes, but in a much cleaner and more maintainable structure that
integrates far better with the Sphinx build system.
This change has been in linux-next for the full 6.15 cycle; the small
number of problems that turned up have been addressed, seemingly to
everybody's satisfaction. The Perl kernel-doc script remains in tree (as
scripts/kernel-doc.pl) and can be used with a command-line option if need
be. Unless some reason to keep it around materializes, it will probably
go away in 6.17.
Credit goes to Mauro Carvalho Chehab for doing all this work.
- Some RTLA documentation updates
- A handful of Chinese translations
- The usual collection of typo fixes, general updates, etc.

rust: str: take advantage of the -> Result support in KUnit #[test]'s
Since now we have support for returning `-> Result`s, we can convert some of these tests to use the feature, and serve as a first user for it too. Thus convert them, which allows us to remove some `unwrap()`s. We keep the actual assertions we want to make as explicit ones with `assert*!`s.

Simplify the `format!` macro used in the tests by using `CString::try_from_fmt` and directly `unwrap()`ing.

rust: add kunit_tests to the prelude
It is convenient to have certain things in the `kernel` prelude, and means kernel developers will find it even easier to start writing tests.

rust: kunit: support checked -> Results in KUnit #[test]s
Currently, return values of KUnit `#[test]` functions are ignored.
Thus introduce support for `-> Result` functions by checking their
returned values.
At the same time, require that test functions return `()` or `Result<T,
E>`, which should avoid mistakes, especially with non-`#[must_use]`
types. Other types can be supported in the future if needed.
With this, a failing test like:
#[test]
fn my_test() -> Result {
f()?;
Ok(())
}
will output:
[ 3.744214] KTAP version 1
[ 3.744287] # Subtest: my_test_suite
[ 3.744378] # speed: normal
[ 3.744399] 1..1

rust: kunit: support KUnit-mapped assert! macros in #[test]s
The KUnit `#[test]` support that landed recently is very basic and does
not map the `assert*!` macros into KUnit like the doctests do, so they
panic at the moment.
Thus implement the custom mapping in a similar way to doctests, reusing
the infrastructure there.
In Rust 1.88.0, the `file()` method in `Span` may be stable [1]. However,
it was changed recently (from `SourceFile`), so we need to do something
different in previous versions. Thus create a helper for it and use it
to get the path.
With this, a failing test suite like:
#[kunit_tests(my_test_suite)]
mod tests {
use super::*;
#[test]
fn my_first_test() {
assert_eq!(42, 43);
}
#[test]
fn my_second_test() {
assert!(42 >= 43);
}
}
will properly map back to KUnit, printing something like:
[ 1.924325] KTAP version 1
[ 1.924421] # Subtest: my_test_suite
[ 1.924506] # speed: normal
[ 1.924525] 1..2
[ 1.926385] # my_first_test: ASSERTION FAILED at rust/kernel/lib.rs:251
[ 1.926385] Expected 42 == 43 to be true, but is false
[ 1.928026] # my_first_test.speed: normal
[ 1.928075] not ok 1 my_first_test
[ 1.928723] # my_second_test: ASSERTION FAILED at rust/kernel/lib.rs:256
[ 1.928723] Expected 42 >= 43 to be true, but is false
[ 1.929834] # my_second_test.speed: normal
[ 1.929868] not ok 2 my_second_test
