Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
In some cs42l43 systems a couple of cs35l56 amplifiers are attached
to the cs42l43's SPI and I2S. On Windows the cs42l43 is controlled
by a SDCA class driver and these two amplifiers are controlled by
firmware running on the cs42l43. However, under Linux the decision
was made to interact with the cs42l43 directly, affording the user
greater control over the audio system. However, this has resulted
in an issue where these two bridged cs35l56 amplifiers are not
populated in ACPI and must be added manually. There is at least an
SDCA extension unit DT entry we can key off.
The process of adding this is handled using a software node, firstly the
ability to add native chip selects to software nodes must be added.
Secondly, an additional flag for naming the SPI devices is added this
allows the machine driver to key to the correct amplifier. Then finally,
the cs42l43 SPI driver adds the two amplifiers directly onto its SPI
bus.
An additional series will follow soon to add the audio machine driver
parts (in the sof-sdw driver), however that is fairly orthogonal to
this part of the process, getting the actual amplifiers registered.
My old NEC address has been removed, so update MAINTAINERS and .mailmap to

Add two compatibles for binman entries, as a starting point for the
schema.
Note that, after discussion on v2, we decided to keep the existing
meaning of label so as not to require changes to existing userspace
software when moving to use binman nodes to specify the firmware
layout.
Note also that, after discussion on v6, we decided to use the same
'fixed-partition' schema for the binman features, so this version
adds a new 'binman.yaml' file providing the new compatibles to the
existing partition.yaml binding.

.. so this can start re-using existing lib.sh infra in next patches.
Several of these scripts will not work, e.g. because they assume
rp_filter is disabled, or reliance on a particular version/flavor
of "netcat" tool.
Add config settings for them.
nft_trans_stress.sh script is removed, it also exists in the nftables
userspace selftests. I do not see a reason to keep two versions in
different repositories/projects.
The settings file is removed for now:
It was used to increase the timeout to avoid slow scripts from getting
zapped by the 45s timeout, but some of the slow scripts can be sped up.
Re-add it later for scripts that cannot be sped up easily.
Update MAINTAINERS to reflect that future updates to netfilter
scripts should go through netfilter-devel@.

Add a script which produces a Flat Image Tree (FIT), a single file
containing the built kernel and associated devicetree files.
Compression defaults to gzip which gives a good balance of size and
performance.
The files compress from about 86MB to 24MB using this approach.
The FIT can be used by bootloaders which support it, such as U-Boot
and Linuxboot. It permits automatic selection of the correct
devicetree, matching the compatible string of the running board with
the closest compatible string in the FIT. There is no need for
filenames or other workarounds.
Add a 'make image.fit' build target for arm64, as well.
The FIT can be examined using 'dumpimage -l'.
This uses the 'dtbs-list' file but processes only .dtb files, ignoring
the overlay .dtbo files.
This features requires pylibfdt (use 'pip install libfdt'). It also
requires compression utilities for the algorithm being used. Supported
compression options are the same as the Image.xxx files. Use
FIT_COMPRESSION to select an algorithm other than gzip.
While FIT supports a ramdisk / initrd, no attempt is made to support
this here, since it must be built separately from the Linux build.

Add support for Tegra Security Engine which can accelerate various
crypto algorithms. The Engine has two separate instances within for
AES and HASH algorithms respectively.
The driver registers two crypto engines - one for AES and another for
HASH algorithms and these operate independently and both uses the host1x
bus. Additionally, it provides hardware-assisted key protection for up
to 15 symmetric keys which it can use for the cipher operations.

Notable user impacting bugs
- On multi device filesystems, recovery was looping in
btree_trans_too_many_iters(). This checks if a transaction has touched
too many btree paths (because of iteration over many keys), and isuses
a restart to drop unneeded paths. But it's now possible for some paths
to exceed the previous limit without iteration in the interior btree
update path, since the transaction commit will do alloc updates for
every old and new btree node, and during journal replay we don't use
the btree write buffer for locking reasons and thus those updates use
btree paths when they wouldn't normally.
- Fix a corner case in rebalance when moving extents on a durability=0
device. This wouldn't be hit when a device was formatted with
durability=0 since in that case we'll only use it as a write through
cache (only cached extents will live on it), but durability can now be
changed on an existing device.
- bch2_get_acl() could rarely forget to handle a transaction restart;
this manifested as the occasional missing acl that came back after
dropping caches.
- Fix a major performance regression on high iops multithreaded write
workloads (only since 6.9-rc1); a previous fix for a deadlock in the
interior btree update path to check the journal watermark introduced a
dependency on the state of btree write buffer flushing that we didn't
want.
- Assorted other repair paths and recovery fixes.

Fedora and openSUSE has started deploying "variable font" [1] format
Noto CJK fonts [2, 3]. "CJK" here stands for "Chinese, Japanese,
and Korean".
Unfortunately, XeTeX/XeLaTeX doesn't understand those fonts for
historical reasons and builds of translations.pdf end up in errors
if such fonts are present on the build host.
To help developers work around the issue, add a script to check the
presence of "variable font" Noto CJK fonts and to emit suggestions.
The script is invoked in the error path of "make pdfdocs" so that the
suggestions are made only when a PDF build actually fails.
The first suggestion is to denylist those "variable font" files by
activating a per-user and command-local fontconfig setting.
For further info and backgrounds, please refer to the header comment
of scripts/check-variable-font.sh newly added in this commit.

This drivers supports the ACPI quickstart button device, which
is used to send manufacturer-specific events to userspace.
Since the meaning of those events is not standardized, userspace
has to use for example hwdb to decode them.
The driver itself is based on an earlier proposal, but contains
some improvements and uses the device wakeup API instead of a
custom sysfs file.

Link topologies containing multiple network PHYs attached to the same
net_device can be found when using a PHY as a media converter for use
with an SFP connector, on which an SFP transceiver containing a PHY can
be used.
With the current model, the transceiver's PHY can't be used for
operations such as cable testing, timestamping, macsec offload, etc.
The reason being that most of the logic for these configuration, coming
from either ethtool netlink or ioctls tend to use netdev->phydev, which
in multi-phy systems will reference the PHY closest to the MAC.
Introduce a numbering scheme allowing to enumerate PHY devices that
belong to any netdev, which can in turn allow userspace to take more
precise decisions with regard to each PHY's configuration.
The numbering is maintained per-netdev, in a phy_device_list.
The numbering works similarly to a netdevice's ifindex, with
identifiers that are only recycled once INT_MAX has been reached.
This prevents races that could occur between PHY listing and SFP
transceiver removal/insertion.
The identifiers are assigned at phy_attach time, as the numbering
depends on the netdevice the phy is attached to. The PHY index can be
re-used for PHYs that are persistent.

have forgotten to fixup when providing support for these initially.
The next two address copier module initialization, most importantly,
silence the gcc 'field-spanning write' false-positive.
The following four:
6/13 ASoC: Intel: avs: Replace risky functions with safer variants

8/13 ASoC: Intel: avs: Test result of avs_get_module_entry()
9/13 ASoC: Intel: avs: Remove dead code
address problems found out by Coverity static analysis tool.
The last two worth mentioning are: recommendation from the firmware team
to wake subsystem from D0ix when starting any pipeline -and- shielding
against invalid period/buffer sizes. Audio format shall be taken into
consideration when calculating either of these.

There are various types of firewalls:
-Peripheral firewalls that filter accesses to peripherals
-Memory firewalls that filter accesses to memories or memory regions
-No type for undefined type of firewall

Since commit 25559c22ce ("tee: add kernel internal client interface"),
it has been a common include/linux/tee_drv.h header file which is shared
to hold TEE subsystem internal bits along with the APIs exposed to the
TEE client drivers. However, this practice is prone to TEE subsystem
internal APIs abuse and especially so with the new TEE implementation
drivers being added to reuse existing functionality.
In order to address this split TEE subsystem internal bits as a separate
header file: include/linux/tee_core.h which should be the one used by
TEE implementation drivers. With that include/linux/tee_drv.h lists only
APIs exposed by TEE subsystem to the TEE client drivers.

The Qualcomm Support entry in MAINTAINERS has served the purpose of both
defining the scope of the Qualcomm support, and to make Qualcomm-related
patches show up on the linux-arm-msm mailing list.
While this continues to serve our needs, it occasionally do create
confusion about the ownership.
Split the entry to clarify which components are maintained under the
qcom-soc tree.

Since the Renesas Ethernet Switch driver was added by Yoshihiro Shimoda,
I started receiving the patches to review for it -- which I was unable to
do, as I don't know this hardware and don't even have the manuals for it.
Fortunately, Shimoda-san has volunteered to be a reviewer for this new
driver, thus let's now split the single entry into 3 per-driver entries,
each with its own reviewer...

Unfortunately, while all this functionality is implemented in ACPI, it's
currently not possible to use ACPI to boot Linux on such Qualcomm
devices. To allow Linux to still support the features provided by EC,
this driver reimplments the relevant ACPI parts. This allows us to boot
the laptop with Device Tree and retain all the features.

Some ARM64 based laptops and computers require vendor/board specific
drivers for their embedded controllers. Even though usually the most
important functionality of those devices is implemented inside ACPI,
unfortunately Linux doesn't currently have great support for ACPI on
platforms like Qualcomm Snapdragon that are used in most ARM64 laptops
today. Instead Linux relies on Device Tree for Qualcomm based devices
and it's significantly easier to reimplement the EC functionality in
a dedicated driver than to make use of ACPI code.
This commit introduces a new platform/arm64 subdirectory to give a
place to such drivers for EC-like devices.
A new MAINTAINERS entry is added for this directory. Patches to files in
this directory will be taken up by the platform-drivers-x86 team (i.e.
Hans de Goede and Ilpo Järvinen) with additional review from Bryan
O'Donoghue to represent ARM64 maintainers.

These are changes that for some reason ended up not making it into the
first four branches but that should still make it into 6.9:
- A rework of the omap clock support that touches both drivers and
device tree files
- The reset controller branch changes that had a dependency on late
bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the
drivers branch
- The RISC-V/starfive, RISC-V/microchip and ARM/Broadcom devicetree
changes that got delayed and needed some extra time in linux-next

"These are changes that for some reason ended up not making it into the
first four branches but that should still make it into 6.9:
- A rework of the omap clock support that touches both drivers and
device tree files
- The reset controller branch changes that had a dependency on late
bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the
drivers branch
- The RISC-V/starfive, RISC-V/microchip and ARM/Broadcom devicetree

I'm sending you the sysctl pull request after following Luis' suggestion to
become a maintainer. If you see that something is missing, get back to me with
how to improve and I'll include your feedback in the following PRs.
Here is a summary of the changes included in this PR:
* New shared repo for sysctl maintenance
* check-sysctl-docs adjustment for API changes by Thomas Weißschuh
This is a non-functional PR. Additional testing is required for the rest of the
pending changes. Future kernel pull requests will include the removal of the
empty elements (sentinels) from sysctl arrays in the kernel/, net/, mm/ and
security/ dirs. After that, the superfluous check for procname == NULL will be
removed. And the push to avoid bloating the kernel as these arrays move out of
kernel/sysctl.c will be completed.
Even though Thomas' changes went into sysctl-next after v6.8-rc5 (3 weeks in
linux-next), I include them as they contained no functional changes and
therefore have little chance of resulting in an error/regression. Finally the
new shared repo is now picked up by linux-next and is the source for upcoming
sysctl changes.

Merge tag 'cxl-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"CXL has mechanisms to enumerate the performance characteristics of
memory devices. Those mechanisms allow Linux to build the equivalent
of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That
capability is necessary because static ACPI can not represent dynamic
CXL configurations (and reconfigurations).
So, building on the v6.8 work to add "Quality of Service" enumeration,
this update plumbs CXL "access coordinates" (read/write access latency
and bandwidth) in all the same places that ACPI HMAT feeds similar
data. Follow-on patches from the -mm side can then use that data to
feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to
drivers/base/.
The other feature update this cycle is support for CXL error injection
via the ACPI EINJ module. That facility enables injection of bus
protocol errors provided the user knows the magic address values to
insert in the interface. To hide that magic, and make this easier to
use, new error injection attributes were added to CXL debugfs. That
interface injects the errors relative to a CXL object rather than
require user tooling to know how to lookup and inject RCRB (Root
Complex Register Block) addresses into the raw EINJ debugfs interface.
It received some helpful review comments from Tony, but no explicit
acks from the ACPI side. The primary user visible change for existing
EINJ users is that they may find that einj.ko was already loaded by
cxl_core.ko. Previously, einj.ko was only loaded on demand.
The usual collection of miscellaneous cleanups are also present this
cycle.
Summary:
- Supplement ACPI HMAT reported memory performance with native CXL
memory performance enumeration
- Add support for CXL error injection via the ACPI EINJ mechanism
- Cleanup CXL DOE and CDAT integration
- Miscellaneous cleanups and fixes"

- Add warning in unlikely case that device is not captured with
driver_override. (Kunwu Chan)
- Error handling improvements in mlx5-vfio-pci to detect firmware
tracking object error states, logging of firmware error syndrom,
and releasing of firmware resources in aborted migration sequence.
(Yishai Hadas)
- Correct an un-alphabetized VFIO MAINTAINERS entry.
(Alex Williamson)
- Make the mdev_bus_type const and also make the class struct const
for a couple of the vfio-mdev sample drivers. (Ricardo B. Marliere)
- Addition of a new vfio-pci variant driver for the GPU of NVIDIA's
Grace-Hopper superchip. During initialization of the chip-to-chip
interconnect in this hardware module, the PCI BARs of the device
become unused in favor of a faster, coherent mechanism for exposing
device memory. This driver primarily changes the VFIO
representation of the device to masquerade this coherent aperture
to replace the physical PCI BARs for userspace drivers. This also
incorporates use of a new vma flag allowing KVM to use write
combining attributes for uncached device memory. (Ankit Agrawal)
- Reset fixes and cleanups for the pds-vfio-pci driver. Save and
restore files were previously leaked if the device didn't pass
through an error state, this is resolved and later re-fixed to
prevent access to the now freed files. Reset handling is also
refactored to remove the complicated deferred reset mechanism.
(Brett Creeley)
- Remove some references to pl330 in the vfio-platform amba
driver. (Geert Uytterhoeven)
- Remove twice redundant and ugly code to unpin incidental pins
of the zero-page. (Alex Williamson)
- Deferred reset logic is also removed from the hisi-acc-vfio-pci
driver as a simplification. (Shameer Kolothum)
- Enforce that mlx5-vfio-pci devices must support PRE_COPY and
remove resulting unnecessary code. There is no device firmware
that has been available publicly without this support.
(Yishai Hadas)
- Switch over to using the .remove_new callback for vfio-platform
in support of the broader transition for a void remove function.
(Uwe Kleine-König)
- Resolve multiple issues in interrupt code for VFIO bus drivers
that allow calling eventfd_signal() on a NULL context. This
also remove a potential race in INTx setup on certain hardware
for vfio-pci, races with various mechanisms to mask INTx, and
leaked virqfds in vfio-platform. (Alex Williamson)

some more devm helpers and we seem to be going in the direction of "just turn
this stuff on already and leave me alone!" with the addition of a
devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that into a
genpd that drivers attach instead, but this API should help drivers simplify in
the meantime.
Outside of the devm wrappers, we've got the usual clk driver updates that are
dominated by the major phone SoC vendors (Samsung and Qualcomm) and the
non-critical driver fixes for things like incorrect topology descriptions and
wrong registers or bit fields. More details are below, but I'd say that it
looks pretty ordinary. The only thing that really jumps out at me is the
Renesas clk driver that's ignoring clks that are assigned to remote processors
in DeviceTree. That's a new feature that they're using to avoid marking clks as
CLK_IGNORE_UNUSED based on the configuration of the system.
Core:
- Increase dev_id len for clkdev lookups
- Add a devm_clk_bulk_get_all_enable() API to get and enable all clks
for a device
- Add a devm variant of clk_rate_exclusive_get()
New Drivers:
- Display, TCSR, GPU, and Camera clock controllers for Qualcomm's X1 Elite SoC
- Google GS101 PERIC0 and PERIC1 clock controllers
- Exynos850 PDMA clocks
- Exynos850 CPU cluster 0 and 1 (CMU_CPUCLK0/CMU_CPUCLK1) clock controllers
Removed Drivers:
- Remove the unused Qualcomm sc7180 modem clk driver
Updates:
- Fix some static checker errors in the Hisilicon clk driver
- Polarfire MSSPLL hardware has 4 output clocks (the driver supported
previously only one output); each of these 4 outputs feed dividers and the
output of each divider feed individual hardware blocks (e.g. CAN, Crypto,
eMMC); individual hardware block drivers need to control their clocks thus
clock driver support was added for all MSSPLL output clocks
- Typo fixes in the Qualcomm IPQ5018 GCC driver
- Add "qdss_at" clk on Qualcomm IPQ6018, needed for WiFi
- Properly terminate frequency tables in different Qualcomm clk drivers
- Add MDSS, crypto, and SDCC resets on Qualcomm MSM8953
- Add missing UFS CLKREF clks on Qualcomm SC8180X
- Avoid significant delays during boot by adding a softdep on rpmhpd to
Qualcomm SDM845 gcc driver
- Add QUPv3 RCGS w/ DFS and video resets to Qualcomm SM8150 GCC driver
- Fix the custom GPU GX "do-nothing" method in the Qualcomm GDSC driver
- Add an external regulator to GX GDSC on Qualcomm SC8280XP GPU clk driver
- Switch display, GPU, video, and camera Qualcomm clk drivers to
module_platform_driver()
- Set a longer delay for Venus resets on many Qualcomm SoCs
- Correct the GDSC wait times in the Qualcomm SDM845 display clk driver
- Fix clock listing Oops on Amlogic axg
- New pll-rate for Rockchip rk3568
- i2s rate improvements for Rockchip rk3399
- Rockchip rk3588 syscon clock fixes and removal of overall clock-number from
the rk3588 binding header
- A prerequisite for later improvements to the Rockchip rk3588 linked clocks
- Minor clean-ups and error handling improvements in both composite-8m and SCU
i.MX clock drivers
- Fix for SAI_MCLK_SEL definition for i.MX8MP
- Register the Samsung CMU MISC clock controller earlier, so the Multi Core
Timer clocksource can use it on Google GS101
- Propagate Exynos850 SPI IPCLK rate change to parents, so the SPI will get
proper clock rates
- Refactor the generic Samsung CPU clock controllers code, preparing it for
supporting Exynos850 CPU clocks
- Fix some clk kerneldoc warnings
- Add Ethernet, SDHI, DMA, and HyperFLASH/QSPI (RPC-IF) clocks on Renesas
R-Car V4M
- Ignore all clocks which are assigned to a non-Linux system in the Renesas
clk driver
- Add watchdog clock on Renesas RZ/G3S
- Add camera (CRU) clock and reset on Renesas RZ/G2UL
- Add support for the Renesas R-Car V4M (R8A779H0) SoC
- Convert some clk bindings to YAML so they can be validated

from hotplugged memory rather than only from main memory. Series
"implement "memmap on memory" feature on s390".
- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"
"mm: convert mm counter to take a folio"
- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series "mm:
zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to
control the memmap_on_memory setting when the dax device is hotplugged
as system memory.
- Johannes Weiner has added the large series "mm: zswap: cleanups",
which does that.
- More DAMON work from SeongJae Park in the series
"mm/damon: make DAMON debugfs interface deprecation unignorable"
"selftests/damon: add more tests for core functionalities and corner cases"
"Docs/mm/damon: misc readability improvements"
"mm/damon: let DAMOS feeds and tame/auto-tune itself"
- In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension" Rakie Kim has developed a new mempolicy interleaving policy
wherein we allocate memory across nodes in a weighted fashion rather
than uniformly. This is beneficial in heterogeneous memory environments
appearing with CXL.
- Christophe Leroy has contributed some cleanup and consolidation work
against the ARM pagetable dumping code in the series "mm: ptdump:
Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute".
- Luis Chamberlain has added some additional xarray selftesting in the
series "test_xarray: advanced API multi-index tests".
- Muhammad Usama Anjum has reworked the selftest code to make its
human-readable output conform to the TAP ("Test Anything Protocol")
format. Amongst other things, this opens up the use of third-party
tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the process
has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown situations.
The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings" Ryan
Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's series
"Address some contpte nits" provides some followup work.
- In the series "mm/hugetlb: Restore the reservation" Breno Leitao has
fixed an obscure hugetlb race which was causing unnecessary page faults.
He has also added a reproducer under the selftest code.
- In the series "selftests/mm: Output cleanups for the compaction test",
Mark Brown did what the title claims.
- Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring".
- Even more zswap material from Nhat Pham. The series "fix and extend
zswap kselftests" does as claimed.
- In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in
our handling of DAX on archiecctures which have virtually aliasing data
caches. The arm architecture is the main beneficiary.
- Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic
improvements in worst-case mmap_lock hold times during certain
userfaultfd operations.
- Some page_owner enhancements and maintenance work from Oscar Salvador
in his series
"page_owner: print stacks and their outstanding allocations"
"page_owner: Fixup and cleanup"
- Uladzislau Rezki has contributed some vmalloc scalability improvements
in his series "Mitigate a vmap lock contention". It realizes a 12x
improvement for a certain microbenchmark.
- Some kexec/crash cleanup work from Baoquan He in the series "Split
crash out from kexec and clean up related config items".
- Some zsmalloc maintenance work from Chengming Zhou in the series
"mm/zsmalloc: fix and optimize objects/page migration"
"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"
- Zi Yan has taught the MM to perform compaction on folios larger than
order=0. This a step along the path to implementaton of the merging of
large anonymous folios. The series is named "Enable >0 order folio
memory compaction".
- Christoph Hellwig has done quite a lot of cleanup work in the
pagecache writeback code in his series "convert write_cache_pages() to
an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".
- Zi Yan has changed the page splitting code so we can split huge pages
into sizes other than order-0 to better utilize large folios. The
series is named "Split a folio to any lower order folios".
- David Hildenbrand has contributed the series "mm: remove
total_mapcount()", a cleanup.
- Matthew Wilcox has sought to improve the performance of bulk memory
freeing in his series "Rearrange batched folio freeing".
- Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
provides large improvements in bootup times on large machines which are
configured to use large numbers of hugetlb pages.
- Matthew Wilcox's series "PageFlags cleanups" does that.
- Qi Zheng's series "minor fixes and supplement for ptdesc" does that
also. S390 is affected.
- Cleanups to our pagemap utility functions from Peter Xu in his series
"mm/treewide: Replace pXd_large() with pXd_leaf()".
- Nico Pache has fixed a few things with our hugepage selftests in his
series "selftests/mm: Improve Hugepage Test Handling in MM Selftests".
- Also, of course, many singleton patches to many things. Please see
the individual changelogs for details.

This was a relatively calm development cycle. Most of changes are
rather small device-specific fixes and enhancements. The only
significant changes in ALSA core are code refactoring with the recent
cleanup infrastructure, which should bring no functionality changes.
Some highlights below:
Core:
- Lots of cleanups in ALSA core code with automatic kfree cleanup
and locking guard macros
- New ALSA core kunit test
ASoC:
- SoundWire support for AMD ACP 6.3 systems
- Support for reporting version information for AVS firmware
- Support DSPless mode for Intel Soundwire systems
- Support for configuring CS35L56 amplifiers using EFI calibration
data
- Log which component is being operated on as part of power management
trace events.
- Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x
HD- and USB-audio:
- More Cirrus HD-audio codec support
- TAS2781 HD-audio codec fixes
- Scarlett2 mixer fixes
Others:
- Enhancement of virtio driver for audio control supports
- Cleanups of legacy PM code with new macros
- Firewire sound updates

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Consolidate interrupt related code in irq.c (Ilpo Järvinen)
- Reduce kernel size by replacing sysfs resource macros with
functions (Ilpo Järvinen)
- Reduce kernel size by compiling sysfs support only when
CONFIG_SYSFS=y (Lukas Wunner)
- Avoid using Extended Tags on 3ware-9650SE Root Port to work around
an apparent hardware defect (Jörg Wedekind)
Resource management:
- Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)
- Move pci_iomap.c and other PCI-specific devres code to drivers/pci
(Philipp Stanner)
- Consolidate PCI devres code in devres.c (Philipp Stanner)
Power management:
- Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't
know how to return correctly to D0, and remove previous quirk that
wasn't as specific (Daniel Drake)
- Allow runtime PM when the driver enables it but doesn't need any
runtime PM callbacks (Raag Jadav)
- Drain runtime-idle callbacks before driver removal to avoid races
between .remove() and .runtime_idle(), which caused intermittent
page faults when the rtsx .runtime_idle() accessed registers that
its .remove() had already unmapped (Rafael J. Wysocki)
Virtualization:
- Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
with VFIO, e.g., for professional audio software on many Apple
machines, at the cost of leaking state between VMs (Edmund Raile)
Error handling:
- Print all logged TLP Prefixes, not just the first, after AER or DPC
errors (Ilpo Järvinen)
- Quirk the DPC PIO log size for Intel Raptor Lake Root Ports, which
still don't advertise a legal size (Paul Menzel)
- Ignore expected DPC Surprise Down errors on hot removal (Smita
Koralahalli)
- Block runtime suspend while handling AER errors to avoid races that
prevent the device form being resumed from D3hot (Stanislaw
Gruszka)
Peer-to-peer DMA:
- Use atomic XA allocation in RCU read section (Christophe JAILLET)
ASPM:
- Collect bits of ASPM-related code that we need even without
CONFIG_PCIEASPM into aspm.c (David E. Box)
- Save/restore L1 PM Substates config for suspend/resume (David E.
Box)
- Update save_save when ASPM config is changed, so a .slot_reset()
during error recovery restores the changed config, not the
.probe()-time config (Vidya Sagar)
Endpoint framework:
- Refactor and improve pci_epf_alloc_space() API (Niklas Cassel)
- Clean up endpoint BAR descriptions (Niklas Cassel)
- Fix ntb_register_device() name leak in error path (Yang Yingliang)
- Return actual error code for pci_vntb_probe() failure (Yang
Yingliang)
Broadcom STB PCIe controller driver:
- Fix MDIO write polling, which previously never waited for
completion (Jonathan Bell)
Cadence PCIe endpoint driver:
- Clear the ARI "Next Function Number" of last function (Jasko-EXT
Wojciech)
Freescale i.MX6 PCIe controller driver:
- Simplify by replacing switch statements with function pointers for
different hardware variants (Frank Li)
- Simplify by using clk_bulk*() API (Frank Li)
- Remove redundant DT clock and reg/reg-name details (Frank Li)
- Add i.MX95 DT and driver support for both Root Complex and Endpoint
mode (Frank Li)
Microsoft Hyper-V host bridge driver:
- Reduce memory usage by limiting ring buffer size to 16KB instead of
4 pages (Michael Kelley)
Qualcomm PCIe controller driver:
- Add X1E80100 DT and driver support (Abel Vesa)
- Add DT 'required-opps' for SoCs that require a minimum performance
level (Johan Hovold)
- Make DT 'msi-map-mask' optional, depending on how MSI interrupts
are mapped (Johan Hovold)
- Disable ASPM L0s for sc8280xp, sa8540p and sa8295p because the PHY
configuration isn't tuned correctly for L0s (Johan Hovold)
- Split dt-binding qcom,pcie.yaml into qcom,pcie-common.yaml and
separate files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150,
SM8250, SM8350, SM8450, SM8550 for easier reviewing (Krzysztof
Kozlowski)
- Enable BDF to SID translation by disabling bypass mode (Manivannan
Sadhasivam)
- Add endpoint MHI support for Snapdragon SA8775P SoC (Mrinmay
Sarkar)
Synopsys DesignWare PCIe controller driver:
- Allocate 64-bit MSI address if no 32-bit address is available (Ajay
Agarwal)
- Fix endpoint Resizable BAR to actually advertise the required 1MB
size (Niklas Cassel)
MicroSemi Switchtec management driver:
- Release resources if the .probe() fails (Christophe JAILLET)
Miscellaneous:
- Make pcie_port_bus_type const (Ricardo B. Marliere)"

No core changes this time around.
New drivers:
- New driver for Renesas R8A779H0 also known as R-Car V4M.
- New driver for the Awinic AW9523/B I2C GPIO expander.
I found this living out-of-tree in OpenWrt as an upstream
attempt had stalled on the finishing line, so I picked it
up and finished the job.
Improvements:
- The Nomadik pin control driver was for years re-used out of
tree for the ST STA chips, and now the IP was re-used in a
MIPS automotive SoC called MobilEyeq5, so it has been split
in pin control and GPIO drivers so the latter can be reused
by MobilEyeq5. (Along with a long list of cleanups.)
- A lot of overall cleanup and tidying up.

Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to GPIO device
structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being unbound while
the API calls are in progress

can be obtained from the GPIO device structure
- move some of the information contained in struct gpio_chip to struct
gpio_device to further reduce the need to dereference the former
- pass the GPIO device struct instead of the GPIO chip to sysfs callback to,
again, reduce the need for accessing the latter
- get GPIO descriptors from the GPIO device, not from the chip for the same
reason
- allow for mostly lockless operation of the GPIO driver API: assure
consistency with SRCU and atomic operations

requested
- remove leftover typedefs
- pass the consumer device to GPIO core in devm_fwnode_gpiod_get_index() for
improved logging

- don't warn about removing GPIO chips with descriptors still held by users as
we can now handle this situation gracefully
- remove unused logging helpers

menuconfig (before it was always built for i.MX cofigs)

Pull gpio updates from Bartosz Golaszewski:
"The biggest feature is the locking overhaul. Up until now the
synchronization in the GPIO subsystem was broken. There was a single
spinlock "protecting" multiple data structures but doing it wrong (as
evidenced by several places where it would be released when a sleeping
function was called and then reacquired without checking the protected
state).
We tried to use an RW semaphore before but the main issue with GPIO is
that we have drivers implementing the interfaces in both sleeping and
non-sleeping ways as well as user-facing interfaces that can be called
both from process as well as atomic contexts. Both ends converge in
the same code paths that can use neither spinlocks nor mutexes. The
only reasonable way out is to use SRCU and go mostly lockless. To that
end: we add several SRCU structs in relevant places and use them to
assure consistency between API calls together with atomic reads and
writes of GPIO descriptor flags where it makes sense.
This code has spent several weeks in next and has received several
fixes in the first week or two after which it stabilized nicely. The
GPIO subsystem is now resilient to providers being suddenly unbound.
We managed to also remove the existing character device RW semaphore
and the obsolete global spinlock.
Other than the locking rework we have one new driver (for Chromebook
EC), much appreciated documentation improvements from Kent and the
regular driver improvements, DT-bindings updates and GPIOLIB core
tweaks.
Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to
GPIO device structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being

Move CXL protocol error types from einj.c (now einj-core.c) to einj-cxl.c.
einj-cxl.c implements the necessary handling for CXL protocol error
injection and exposes an API for the CXL core to use said functionality,
while also allowing the EINJ module to be built without CXL support.
Because CXL error types targeting CXL 1.0/1.1 ports require special
handling, only allow them to be injected through the new cxl debugfs
interface (next commit) and return an error when attempting to inject
through the legacy interface.

Core & protocols
----------------
- Large effort by Eric to lower rtnl_lock pressure and remove locks:
- Make commonly used parts of rtnetlink (address, route dumps etc.)
lockless, protected by RCU instead of rtnl_lock.
- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core
instead of once for each driver / callback.
- Remove locks / serialization in the socket diag interface.
- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
- Remove the dev_base_lock, depend on RCU where necessary.
- Support busy polling on a per-epoll context basis. Poll length
and budget parameters can be set independently of system defaults.
- Introduce struct net_hotdata, to make sure read-mostly global config
variables fit in as few cache lines as possible.
- Add optional per-nexthop statistics to ease monitoring / debug
of ECMP imbalance problems.
- Support TCP_NOTSENT_LOWAT in MPTCP.
- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.
- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.
- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.
- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.
- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for
use on fastpaths).
- Speed up scanning for expired routes by keeping a dedicated list.
- Speed up "generic" XDP by trying harder to avoid large allocations.
- Support attaching arbitrary metadata to netconsole messages.
Things we sprinkled into general kernel code
--------------------------------------------
- Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce
VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena).
- Rework selftest harness to enable the use of the full range of
ksft exit code (pass, fail, skip, xfail, xpass).
Netfilter
---------
- Allow userspace to define a table that is exclusively owned by a daemon
(via netlink socket aliveness) without auto-removing this table when
the userspace program exits. Such table gets marked as orphaned and
a restarting management daemon can re-attach/regain ownership.
- Speed up element insertions to nftables' concatenated-ranges set type.
Compact a few related data structures.
BPF
---
- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.
- Introduce bpf_arena which is sparse shared memory region between BPF
program and user space where structures inside the arena can have
pointers to other areas of the arena, and pointers work seamlessly
for both user-space programs and BPF programs.
- Introduce may_goto instruction that is a contract between the verifier
and the program. The verifier allows the program to loop assuming it's
behaving well, but reserves the right to terminate it.
- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.
- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops type.
- Add support for retrieval of cookies for perf/kprobe multi links.
- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF firewalls.
- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF objects.
Wireless
--------
- Add SPP (signaling and payload protected) AMSDU support.
- Support wider bandwidth OFDMA, as required for EHT operation.
Driver API
----------
- Major overhaul of the Energy Efficient Ethernet internals to support
new link modes (2.5GE, 5GE), share more code between drivers
(especially those using phylib), and encourage more uniform behavior.
Convert and clean up drivers.
- Define an API for querying per netdev queue statistics from drivers.
- IPSec: account in global stats for fully offloaded sessions.
- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.
- Enable Rx hashing (RSS) on GTP protocol fields.
Misc
----
- Improvements and refactoring all over networking selftests.
- Create uniform module aliases for TC classifiers, actions,
and packet schedulers to simplify creating modprobe policies.
- Address all missing MODULE_DESCRIPTION() warnings in networking.
- Extend the Netlink descriptions in YAML to cover message encapsulation
or "Netlink polymorphism", where interpretation of nested attributes
depends on link type, classifier type or some other "class type".

Pull hardening updates from Kees Cook:
"As is pretty normal for this tree, there are changes all over the
place, especially for small fixes, selftest improvements, and improved
macro usability.
Some header changes ended up landing via this tree as they depended on
the string header cleanups. Also, a notable set of changes is the work
for the reintroduction of the UBSAN signed integer overflow sanitizer
so that we can continue to make improvements on the compiler side to
make this sanitizer a more viable future security hardening option.
Summary:
- string.h and related header cleanups (Tanzir Hasan, Andy
Shevchenko)
- VMCI memcpy() usage and struct_size() cleanups (Vasiliy Kovalev,
Harshit Mogalapalli)
- selftests/powerpc: Fix load_unaligned_zeropad build failure
(Michael Ellerman)
- hardened Kconfig fragment updates (Marco Elver, Lukas Bulwahn)
- Handle tail call optimization better in LKDTM (Douglas Anderson)
- Use long form types in overflow.h (Andy Shevchenko)
- Add flags param to string_get_size() (Andy Shevchenko)
- Add Coccinelle script for potential struct_size() use (Jacob
Keller)
- Fix objtool corner case under KCFI (Josh Poimboeuf)
- Drop 13 year old backward compat CAP_SYS_ADMIN check (Jingzi Meng)
- Add str_plural() helper (Michal Wajdeczko, Kees Cook)
- Ignore relocations in .notes section
- Add comments to explain how __is_constexpr() works
- Fix m68k stack alignment expectations in stackinit Kunit test
- Convert string selftests to KUnit
- Add KUnit tests for fortified string functions
- Improve reporting during fortified string warnings
- Allow non-type arg to type_max() and type_min()
- Allow strscpy() to be called with only 2 arguments
- Add binary mode to leaking_addresses scanner
- Various small cleanups to leaking_addresses scanner
- Adding wrapping_*() arithmetic helper
- Annotate initial signed integer wrap-around in refcount_t
- Add explicit UBSAN section to MAINTAINERS
- Fix UBSAN self-test warnings
- Simplify UBSAN build via removal of CONFIG_UBSAN_SANITIZE_ALL
- Reintroduce UBSAN's signed overflow sanitizer"

There is very little going on with new SoC support this time, all the
new chips are variations of others that we already support, and they
are all based on ARMv8 cores:
- Mediatek MT7981B (Filogic 820) and MT7988A (Filogic 880) are
networking SoCs designed to be used in wireless routers, similar
to the already supported MT7986A (Filogic 830).
- NXP i.MX8DXP is a variant of i.MX8QXP, with two CPU cores less.
These are used in many embedded and industrial applications.
- Renesas R8A779G2 (R-Car V4H ES2.0) and R8A779H0 (R-Car V4M)
are automotive SoCs.
- TI J722S is another automotive variant of its K3 family,
related to the AM62 series.
There are a total of 7 new arm32 machines and 45 arm64 ones, including
- Two Android phones based on the old Tegra30 chip
- Two machines using Cortex-A53 SoCs from Allwinner, a mini PC and
a SoM development board
- A set-top box using Amlogic Meson G12A S905X2
- Eight embedded board using NXP i.MX6/8/9
- Three machines using Mediatek network router chips
- Ten Chromebooks, all based on Mediatek MT8186
- One development board based on Mediatek MT8395 (Genio 1200)
- Seven tablets and phones based on Qualcomm SoCs, most of them
from Samsung.
- A third development board for Qualcomm SM8550 (Snapdragon 8 Gen 2)
- Three variants of the "White Hawk" board for Renesas
automotive SoCs
- Ten Rockchips RK35xx based machines, including NAS, Tablet,
Game console and industrial form factors.
- Three evaluation boards for TI K3 based SoCs
The other changes are mainly the usual feature additions for existing hardware,
cleanups, and dtc compile time fixes. One notable change is the inclusion
of PowerVR SGX GPU nodes on TI SoCs.

collects and manages previously encountered hw errors in order to
save them to persistent storage across reboots. Previously recorded
errors are "replayed" upon reboot in order to poison memory which has
caused said errors in the past.
The main use case is stacked, on-chip memory which cannot simply be
replaced so poisoning faulty areas of it and thus making them
inaccessible is the only strategy to prolong its lifetime.
- Add an AMD address translation library glue which converts the
reported addresses of hw errors into system physical addresses in
order to be used by other subsystems like memory failure, for
example. Add support for MI300 accelerators to that library.
- igen6: Add support for Alder Lake-N SoC
- i10nm: Add Grand Ridge support

Pull EDAC updates from Borislav Petkov:
- Add a FRU (Field Replaceable Unit) memory poison manager which
collects and manages previously encountered hw errors in order to
save them to persistent storage across reboots. Previously recorded
errors are "replayed" upon reboot in order to poison memory which has
caused said errors in the past.
The main use case is stacked, on-chip memory which cannot simply be
replaced so poisoning faulty areas of it and thus making them
inaccessible is the only strategy to prolong its lifetime.
- Add an AMD address translation library glue which converts the
reported addresses of hw errors into system physical addresses in
order to be used by other subsystems like memory failure, for
example. Add support for MI300 accelerators to that library.
- igen6: Add support for Alder Lake-N SoC
- i10nm: Add Grand Ridge support
- The usual fixlets and cleanups

FRED is a replacement for IDT event delivery on x86 and addresses most of
the technical nightmares which IDT exposes:
1) Exception cause registers like CR2 need to be manually preserved in
nested exception scenarios.
2) Hardware interrupt stack switching is suboptimal for nested exceptions
as the interrupt stack mechanism rewinds the stack on each entry which
requires a massive effort in the low level entry of #NMI code to handle
this.
3) No hardware distinction between entry from kernel or from user which
makes establishing kernel context more complex than it needs to be
especially for unconditionally nestable exceptions like NMI.
4) NMI nesting caused by IRET unconditionally reenabling NMIs, which is a
problem when the perf NMI takes a fault when collecting a stack trace.
5) Partial restore of ESP when returning to a 16-bit segment
6) Limitation of the vector space which can cause vector exhaustion on
large systems.
7) Inability to differentiate NMI sources
FRED addresses these shortcomings by:
1) An extended exception stack frame which the CPU uses to save exception
cause registers. This ensures that the meta information for each
exception is preserved on stack and avoids the extra complexity of
preserving it in software.
2) Hardware interrupt stack switching is non-rewinding if a nested
exception uses the currently interrupt stack.
3) The entry points for kernel and user context are separate and GS BASE
handling which is required to establish kernel context for per CPU
variable access is done in hardware.
4) NMIs are now nesting protected. They are only reenabled on the return
from NMI.
5) FRED guarantees full restore of ESP
6) FRED does not put a limitation on the vector space by design because it
uses a central entry points for kernel and user space and the CPUstores
the entry type (exception, trap, interrupt, syscall) on the entry stack
along with the vector number. The entry code has to demultiplex this
information, but this removes the vector space restriction.
The first hardware implementations will still have the current
restricted vector space because lifting this limitation requires
further changes to the local APIC.
7) FRED stores the vector number and meta information on stack which
allows having more than one NMI vector in future hardware when the
required local APIC changes are in place.
The series implements the initial FRED support by:
- Reworking the existing entry and IDT handling infrastructure to
accomodate for the alternative entry mechanism.
- Expanding the stack frame to accomodate for the extra 16 bytes FRED
requires to store context and meta information
- Providing FRED specific C entry points for events which have information
pushed to the extended stack frame, e.g. #PF and #DB.
- Providing FRED specific C entry points for #NMI and #MCE
- Implementing the FRED specific ASM entry points and the C code to
demultiplex the events
- Providing detection and initialization mechanisms and the necessary
tweaks in context switching, GS BASE handling etc.
The FRED integration aims for maximum code reuse vs. the existing IDT
implementation to the extent possible and the deviation in hot paths like
context switching are handled with alternatives to minimalize the
impact. The low level entry and exit paths are seperate due to the extended
stack frame and the hardware based GS BASE swichting and therefore have no
impact on IDT based systems.
It has been extensively tested on existing systems and on the FRED
simulation and as of now there are know outstanding problems.

- The hierarchical timer pull model
When timer wheel timers are armed they are placed into the timer wheel
of a CPU which is likely to be busy at the time of expiry. This is done
to avoid wakeups on potentially idle CPUs.
This is wrong in several aspects:
1) The heuristics to select the target CPU are wrong by
definition as the chance to get the prediction right is close
to zero.
2) Due to #1 it is possible that timers are accumulated on a
single target CPU
3) The required computation in the enqueue path is just overhead for
dubious value especially under the consideration that the vast
majority of timer wheel timers are either canceled or rearmed
before they expire.
The timer pull model avoids the above by removing the target
computation on enqueue and queueing timers always on the CPU on which
they get armed.
This is achieved by having separate wheels for CPU pinned timers and
global timers which do not care about where they expire.
As long as a CPU is busy it handles both the pinned and the global
timers which are queued on the CPU local timer wheels.
When a CPU goes idle it evaluates its own timer wheels:
- If the first expiring timer is a pinned timer, then the global
timers can be ignored as the CPU will wake up before they expire.
- If the first expiring timer is a global timer, then the expiry time
is propagated into the timer pull hierarchy and the CPU makes sure
to wake up for the first pinned timer.
The timer pull hierarchy organizes CPUs in groups of eight at the
lowest level and at the next levels groups of eight groups up to the
point where no further aggregation of groups is required, i.e. the
number of levels is log8(NR_CPUS). The magic number of eight has been
established by experimention, but can be adjusted if needed.
In each group one busy CPU acts as the migrator. It's only one CPU to
avoid lock contention on remote timer wheels.
The migrator CPU checks in its own timer wheel handling whether there
are other CPUs in the group which have gone idle and have global timers
to expire. If there are global timers to expire, the migrator locks the
remote CPU timer wheel and handles the expiry.
Depending on the group level in the hierarchy this handling can require
to walk the hierarchy downwards to the CPU level.
Special care is taken when the last CPU goes idle. At this point the
CPU is the systemwide migrator at the top of the hierarchy and it
therefore cannot delegate to the hierarchy. It needs to arm its own
timer device to expire either at the first expiring timer in the
hierarchy or at the first CPU local timer, which ever expires first.
This completely removes the overhead from the enqueue path, which is
e.g. for networking a true hotpath and trades it for a slightly more
complex idle path.
This has been in development for a couple of years and the final series
has been extensively tested by various teams from silicon vendors and
ran through extensive CI.
There have been slight performance improvements observed on network
centric workloads and an Intel team confirmed that this allows them to
power down a die completely on a mult-die socket for the first time in
a mostly idle scenario.
There is only one outstanding ~1.5% regression on a specific overloaded
netperf test which is currently investigated, but the rest is either
positive or neutral performance wise and positive on the power
management side.
- Fixes for the timekeeping interpolation code for cross-timestamps:
cross-timestamps are used for PTP to get snapshots from hardware timers
and interpolated them back to clock MONOTONIC. The changes address a
few corner cases in the interpolation code which got the math and logic
wrong.
- Simplifcation of the clocksource watchdog retry logic to automatically
adjust to handle larger systems correctly instead of having more

Pull ntfs update from Christian Brauner:
"This removes the old ntfs driver. The new ntfs3 driver is a full
replacement that was merged over two years ago. We've went through
various userspace and either they use ntfs3 or they use the fuse
version of ntfs and thus build neither ntfs nor ntfs3. I think that's
a clear sign that we should risk removing the legacy ntfs driver.
Quoting from Arch Linux and Debian:
- Debian does neither build the legacy ntfs nor the new ntfs3:
"Not currently built with Debian's kernel packages, 'ntfs' has been
symlinked to 'ntfs-3g' as it relates to fstab and mount commands.
Debian kernels are built without support of the ntfs3 driver
developed by Paragon Software." (cf. [2])
- Archlinux provides ntfs3 as their default since 5.15:
"All officially supported kernels with versions 5.15 or newer are
built with CONFIG_NTFS3_FS=m and thus support it. Before 5.15,
NTFS read and write support is provided by the NTFS-3G FUSE file

It's unmaintained apart from various odd fixes as well. Worst case we
have to reintroduce it if someone really has a valid dependency on it.
But it's worth trying to see whether we can remove it"

fs: Remove NTFS classic
This kselftest next update for Linux 6.9-rc1 consists of:
-- livepatch restructuring to move the module out of lib to be
built as a out-of-tree modules during kselftest build. This
change makes it easier change, debug and rebuild the tests by
running make on the selftests/livepatch directory, which is not
currently possible since the modules on lib/livepatch are build
and installed using the main makefile modules target.
-- livepatch restructuring fixes for problems found by kernel test
robot. The change skips the test if kernel-devel isn't installed
(default value of KDIR), or if KDIR variable passed doesn't exists.
-- resctrl test restructuring and new non-contiguous CBMs CAT test
-- new ktap_helpers to print diagnostic messages, pass/fail tests
based on exit code, abort test, and finish the test.
-- a new test verify power supply properties.
-- a new ftrace to exercise function tracer across cpu hotplug.
-- timeout increase for mqueue test to allow the test to run on
i3.metal AWS instances.
-- minor spelling corrections in several tests.
-- missing gitignore files and changes to existing gitignore files.

This has been quite a small release, there's a lot of driver specific
cleanups and minor enhancements but hardly anything on the core and only
one new driver. Highlights include:
- SoundWire support for AMD ACP 6.3 systems.
- Support for reporting version information for AVS firmware.
- Support DSPless mode for Intel Soundwire systems.
- Support for configuring CS35L56 amplifiers using EFI calibration
data.
- Log which component is being operated on as part of power management
trace events.
- Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x

The ExpressWire protocol is shared between at least KTD2692 and KTD2801
with slight differences such as timings and the former not having a
defined set of pulses for enabling the protocol (possibly because it
does not support PWM unlike KTD2801). Despite these differences the
ExpressWire handling code can be shared between the two, so in
preparation for adding KTD2801 support introduce a library implementing
this protocol.

As discussed on the mailing list, Chester is stepping down from being
the primary maintainer for the s32c platform, and Ghennadi becomes an
additional reviewer.
For the moment, there is no full maintainer for s32c, but Shawn is already
listed as the overall maintainer for 32-bit freescale/nxp platforms
(except layerscape and qoriq) and agreed to merge s32c patches as they
come in and are reviewed by the remaining reviewers.
Adapt the entries in the maintainers file based on the discussion.

Convert test-string_helpers.c to KUnit so it can be easily run with

Failure reporting doesn't need to be open-coded in most places, for
example, forcing a failure in the expected output for upper/lower
testing looks like this:

[12:18:43] Expected dst == strings_upper[i].out, but

Convert test_string.c to KUnit so it can be easily run with everything
else.
Additional text context is retained for failure reporting. For example,
when forcing a bad match, we can see the loop counters reported for the
memset() tests:
[09:21:52] # test_memset64: ASSERTION FAILED at lib/string_kunit.c:93
[09:21:52] Expected v == 0xa2a1a1a1a1a1a1a1ULL, but
[09:21:52] v == -6799976246779207263 (0xa1a1a1a1a1a1a1a1)
[09:21:52] 0xa2a1a1a1a1a1a1a1ULL == -6727918652741279327 (0xa2a1a1a1a1a1a1a1)
[09:21:52] i:0 j:0 k:0

I will lose access to my @.*intel.com e-mail addresses soon so let me
adjust the maintainers entry and update the mailmap too.
While at it consolidate a few other of my old emails to point to the
main one.
