Adding this section will make it easier for contributors to know who to

In furtherance of ongoing efforts to ensure people are aware of who
de-facto maintains/has an interest in specific parts of mm, as well trying
to avoid get_maintainers.pl listing only Andrew and the mailing list for
mm files - establish a reclaim memory management section and add relevant
maintainers/reviewers.
This is a key part of memory management so sensibly deserves its own
section.
This encompasses both 'classical' reclaim and MGLRU and thus reflects this
in the reviewers from both, as well as those who have contributed
specifically on the memcg side of things.

Make Vlastimil maintainer of this section (with thanks to Vlastimil for
agreeing to this!) and add page isolation files for which this section
seem most appropriate.
We may wish to, in future, refactor/rename some of these files to more
logically fit what is actually being performed, but for the time being
this seems the most sensible place.
Additionally, fix the alphabetical ordering of files.

====================
ovpn: pull request for net-next: ovpn 2025-05-15
this is a new version of the previous pull request.
These time I have removed the fixes that we are still discussing,
so that we don't hold the entire series back.
There is a new fix though: it's about properly checking the return value
of skb_to_sgvec_nomark(). I spotted the issue while testing pings larger
than the iface's MTU on a TCP VPN connection.
I have added various Closes and Link tags where applicable, so
that we have references to GitHub tickets and other public discussions.
Since I have resent the PR, I have also added Andrew's Reviewed-by to
the first patch.

Current driver uses static LMTST region allocated by firmware.
Firmware allocated memory for LMTST is available in PF/VF BAR2.
Using this memory have performance impact as this is mapped as
device memory. There is another option to allocate contiguous
memory at run time and map this in LMT MAP table with the
help of AF driver. With this patch dynamic allocated memory
is used for LMTST.

Updates for v6.16
CI:
- uprev mesa
GPU:
- ACD (Adaptive Clock Distribution) support for X1-85. This is required
enable the higher frequencies.
- Drop fictional `address_space_size`. For some older devices, the address
space size is limited to 4GB to avoid potential 64b rollover math problems
in the fw. For these, an `ADRENO_QUIRK_4GB_VA` quirk is added. For
everyone else we get the address space size from the SMMU `ias` (input
address sizes), which is usually 48b.
- Improve robustness when GMU HFI responses time out
- Fix crash when throttling GPU immediately during boot
- Fix for rgb565_predicator on Adreno 7c3
- Remove `MODULE_FIRMWARE()`s for GPU, the GPU can load the firmware after
probe and having partial set of fw (ie. sqe+gmu but not zap) causes problems

Introduce Rust support for the `xarray` data structure:
- Add a rust abstraction for the `xarray` data structure. This abstraction
allows rust code to leverage the `xarray` to store types that implement
`ForeignOwnable`. This support is a dependency for memory backing feature of
the rust null block driver, which is waiting to be merged.
- Set up an entry in MAINTAINERS for the xarray rust support. Patches will go
to the new rust xarray tree and then via the rust subsystem tree for now.
`kernel` crate:
- Allow `ForeignOwnable` to carry information about the pointed-to type. This
helps asserting alignment requirements for the pointer passed to the foreign
language.

Precision Time Management (PTM) mechanism defined in PCIe spec r6.0,
sec 6.21 allows precise coordination of timing information across multiple
components in a PCIe hierarchy with independent local time clocks.
PCI core already supports enabling PTM in the root port and endpoint
devices through PTM Extended Capability registers. But the PTM context
supported by the PTM capable components such as Root Complex (RC) and
Endpoint (EP) controllers were not exposed as of now. Part of the reason is
that the spec doesn't define how the context information is exposed to the
software and left it to the vendor implementation. So there is no
standardized way to get access to the context information and each vendor
have defined their own way.
This commit adds debugfs support to expose the PTM context to userspace
from both PCIe RC and EP controllers. Since the context information is
exposed in a vendor specific way, the debugfs interface allows the
controller drivers to implement callbacks for each attribute, to be called
by the generic PTM driver.
The Controller drivers are expected to call pcie_ptm_create_debugfs() to
create the debugfs attributes for the PTM context and call
pcie_ptm_destroy_debugfs() to destroy them. The drivers should also
populate the relevant callbacks in the 'struct pcie_ptm_ops' structure
based on the controller implementation.
Below PTM context are exposed through debugfs:
PCIe RC

1. PTM Local clock
2. PTM T2 timestamp

Merge tag 'ib-mfd-gpio-nvmem-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd into gpio/for-next
Immutable branch between MFD, GPIO and NVMEM due for the v6.16 merge window
Right now these are performed in kernel/fork.c which is odd and a
violation of separation of concerns, as well as preventing us from
integrating this and related logic into userland VMA testing going
forward.
There is a fly in the ointment - nommu - mmap.c is not compiled if
CONFIG_MMU not set, and neither is vma.c.
To square the circle, let's add a new file - vma_init.c. This will be
compiled for both CONFIG_MMU and nommu builds, and will also form part of
the VMA userland testing.
This allows us to de-duplicate code, while maintaining separation of
concerns and the ability for us to userland test this logic.
Update the VMA userland tests accordingly, additionally adding a
detach_free_vma() helper function to correctly detach VMAs before freeing
them in test code, as this change was triggering the assert for this.

Patch series "move all VMA allocation, freeing and duplication logic to
mm", v3.
Currently VMA allocation, freeing and duplication exist in kernel/fork.c,
which is a violation of separation of concerns, and leaves these functions
exposed to the rest of the kernel when they are in fact internal
implementation details.
Resolve this by moving this logic to mm, and making it internal to vma.c,
vma.h.
This also allows us, in future, to provide userland testing around this
functionality.
We additionally abstract dup_mmap() to mm, being careful to ensure
kernel/fork.c acceses this via the mm internal header so it is not exposed
elsewhere in the kernel.
As part of this change, also abstract initial stack allocation performed
in __bprm_mm_init() out of fs code into mm via the
create_init_stack_vma(), as this code uses vm_area_alloc() and
vm_area_free().
In order to do so sensibly, we introduce a new mm/vma_exec.c file, which
contains the code that is shared by mm and exec. This file is added to
both memory mapping and exec sections in MAINTAINERS so both sets of
maintainers can maintain oversight.
As part of this change, we also move relocate_vma_down() to mm/vma_exec.c
so all shared mm/exec functionality is kept in one place.
We add code shared between nommu and mmu-enabled configurations in order
to share VMA allocation, freeing and duplication code correctly while also
keeping these functions available in userland VMA testing.
This is achieved by adding a mm/vma_init.c file which is also compiled by
the userland tests.
This patch (of 4):
There is functionality that overlaps the exec and memory mapping
subsystems. While it properly belongs in mm, it is important that exec
maintainers maintain oversight of this functionality correctly.
We can establish both goals by adding a new mm/vma_exec.c file which
contains these 'glue' functions, and have fs/exec.c import them.
As a part of this change, to ensure that proper oversight is achieved, add
the file to both the MEMORY MAPPING and EXEC & BINFMT API, ELF sections.
scripts/get_maintainer.pl can correctly handle files in multiple entries
and this neatly handles the cross-over.

We introduced KHO into Linux: A framework that allows Linux to pass
metadata and memory across kexec from Linux to Linux. KHO reuses fdt as
file format and shares a lot of the same properties of firmware-to- Linux
boot formats: It needs a stable, documented ABI that allows for forward
and backward compatibility as well as versioning.
As first user of KHO, we introduced memblock which can now preserve memory
ranges reserved with reserve_mem command line options contents across
kexec, so you can use the post-kexec kernel to read traces from the
pre-kexec kernel.
This patch adds memblock schemas similar to "device" device tree ones to a
new kho bindings directory. This allows us to force contributors to
document the data that moves across KHO kexecs and catch breaking change
during review.

Add the infrastructure to generate Kexec HandOver metadata. Kexec
HandOver is a mechanism that allows Linux to preserve state - arbitrary
properties as well as memory locations - across kexec.
It does so using 2 concepts:
1) KHO FDT - Every KHO kexec carries a KHO specific flattened device tree
blob that describes preserved memory regions. Device drivers can
register to KHO to serialize and preserve their states before kexec.
2) Scratch Regions - CMA regions that we allocate in the first kernel.
CMA gives us the guarantee that no handover pages land in those
regions, because handover pages must be at a static physical memory
location. We use these regions as the place to load future kexec
images so that they won't collide with any handover data.

Prepare for Intel IPU E2000 (GEN3)
This is the first part in introducing RDMA support for idpf.
----------------------------------------------------------------
Tatyana Nikolova says:
To align with review comments, the patch series introducing RDMA
RoCEv2 support for the Intel Infrastructure Processing Unit (IPU)
E2000 line of products is going to be submitted in three parts:
1. Modify ice to use specific and common IIDC definitions and
pass a core device info to irdma.
2. Add RDMA support to idpf and modify idpf to use specific and
common IIDC definitions and pass a core device info to irdma.
3. Add RDMA RoCEv2 support for the E2000 products, referred to as
GEN3 to irdma.
This first part is a 5 patch series based on the original
"iidc/ice/irdma: Update IDC to support multiple consumers" patch
to allow for multiple CORE PCI drivers, using the auxbus.
Patches:
1) Move header file to new name for clarity and replace ice
specific DSCP define with a kernel equivalent one in irdma
2) Unify naming convention
3) Separate header file into common and driver specific info
4) Replace ice specific DSCP define with a kernel equivalent
one in ice
5) Implement core device info struct and update drivers to use it

Add the initial nova-drm driver skeleton.
nova-drm is connected to nova-core through the auxiliary bus and
implements the DRM parts of the nova driver stack.
For now, it implements the fundamental DRM abstractions, i.e. creates a
DRM device and registers it, exposing a three sample IOCTLs.
DRM_IOCTL_NOVA_GETPARAM
- provides the PCI bar size from the bar that maps the GPUs VRAM
from nova-core
DRM_IOCTL_NOVA_GEM_CREATE
- creates a new dummy DRM GEM object and returns a handle
DRM_IOCTL_NOVA_GEM_INFO
- provides metadata for the DRM GEM object behind a given handle
I implemented a small userspace test suite [1] that utilizes this
interface.

Prior to the recently applied commit that permits this merge,
mprotect()'ing a faulted VMA, adjacent to an unfaulted VMA, such that the
two share characteristics would fail to merge due to what appear to be
unintended consequences of commit 965f55dea0 ("mmap: avoid merging
cloned VMAs").
Now we have fixed this bug, assert that we can indeed merge anonymous VMAs
this way.
Also assert that forked source/target VMAs are equally rejected.
Previously, all empty target anon merges with one VMA faulted and the
other unfaulted would be rejected incorrectly, now we ensure that unforked
merge, but forked do not.
Additionally, add the new test file to the MEMORY MAPPING section in
MAINTAINERS, as these tests are explicitly memory mapping related.

1. Quirk framework to handle buggy firmware
With SCMI gaining broader adoption across arm64 platforms, it's
increasingly important to address how we consistently manage out-of-spec
SCMI firmware already deployed in the field. This change introduces a
lightweight quirk framework built around static_keys, enabling developers to:
- Define quirks and their match criteria, which can include:
o A list of compatibles ({ comp, comp2, NULL })
o Vendor ID / Sub-Vendor ID
o Firmware implementation version ranges ([Min_Vers, Max_Vers])
Matching proceeds from the most specific (longest match) to the least
specific. NULL entries are treated as wildcards (i.e., match any value).
This flexibility allows matching very specific combinations or just a
general compatible string.
The quirk code blocks/snippets implementing the workaround are placed near
their intended usage and guarded by a static_key that's tied to the quirk.
Once the SCMI core stack is initialized and retrieves platform info via the
base protocol, any matching quirks will have their associated static_keys
enabled.
2. Quirk for Qualcomm X1E platforms
On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
yet it crashes when the driver attempts to fall back to standard messaging
which is clearly out-of-spec behavior.
To work around this, the new SCMI quirk framework is used to
unconditionally enable FC initialization for this firmware version.
In the future, once the fixed firmware version is identified, an upper
version bound can be added to the quirk match criteria. Alternatively,
matching can be further restricted using a SoC-specific compatible string
if always enabling FC proves problematic elsewhere.
3. Support for NXP i.MX LMM/CPU vendor protocol extensions
The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
These changes integrate the vendor-specific protocol extensions
implementing the LMM and CPU protocols for the i.MX95, facilitating
standardized communication between the operating system and the platform's
firmware, which will be used by remoteproc drivers. The changes also
include the necessary device tree bindings.
4. Miscellaneous cleanups/changes
These mainly include polling support in SCMI raw mode. The cleanups
centralize error logging for SCMI device creation into a single helper
function, consolidate the device matching logic into a single function, and
ensure that devices must have a name for registration—removing support for
unnamed devices when matching drivers and devices for probing. Transport
devices are now excluded from bus matching, and the correct assignment of
the parent device for the arm-scmi platform device is ensured in the
transport drivers.

Fuel Gauge and TCPC have separate and independent I2C addresses,

The GPIO and NVMEM interfaces are accessed via specific commands to the
built-in microprocessor. This driver implements an API that client

Some NETC functionality is controlled using control messages sent to the
hardware using BD ring interface with 32B descriptor similar to transmit
BD ring used on ENETC. This BD ring interface is referred to as command
BD ring. It is used to configure functionality where the underlying
resources may be shared between different entities or being too large to
configure using direct registers. Therefore, a messaging protocol called
NETC Table Management Protocol (NTMP) is provided for exchanging
configuration and management information between the software and the
hardware using the command BD ring interface.
For the management protocol of LS1028A has been retroactively named NTMP
1.0, and its implementation is in enetc_cbdr.c and enetc_qos.c. However,
NTMP of i.MX95 has been upgraded to version 2.0, which is incompatible
with LS1028A, because the message formats have been changed. Therefore,
add the netc-lib driver to support NTMP 2.0 to operate various tables.
Note that, only MAC address filter table and RSS table are supported at
the moment. More tables will be supported in subsequent patches.
It is worth mentioning that the purpose of the netc-lib driver is to
provide some NTMP-based generic interfaces for ENETC and NETC Switch
drivers. Currently, it only supports the configurations of some tables.
Interfaces such as tc flower and debugfs will be added in the future.

Expose the most commonly used TDX MRs (Measurement Registers) as sysfs
attributes. Use the ioctl() interface of /dev/tdx_guest to request a full
TDREPORT for access to other TD measurements.
Directory structure of TDX MRs inside a TDVM is as follows:
/sys/class/misc/tdx_guest
└── measurements
├── mrconfigid
├── mrowner
├── mrownerconfig
├── mrtd:sha384
├── rtmr0:sha384

This sample kernel module demonstrates how to make MRs accessible to user
mode through the tsm-mr library.
Once loaded, this module registers a `miscdevice` that host a set of
emulated measurement registers as shown in the directory tree below.
/sys/class/misc/tsm_mr_sample
└── measurements
├── config_mr
├── report_digest:sha512
├── rtmr0:sha256
├── rtmr1:sha384
├── rtmr_crypto_agile:sha256
├── rtmr_crypto_agile:sha384
└── static_mr:sha384
Among the MRs in this example:
- `config_mr` demonstrates a hashless MR, like MRCONFIGID in Intel TDX or
HOSTDATA in AMD SEV.
- `static_mr` demonstrates a static MR. The suffix `:sha384` indicates its
value is a sha384 digest.
- `rtmr0` is an RTMR with `TSM_MR_F_WRITABLE` **cleared**, preventing
direct extensions; as a result, the attribute `rtmr0:sha256` is
read-only.
- `rtmr1` is an RTMR with `TSM_MR_F_WRITABLE` **set**, permitting direct
extensions; thus, the attribute `rtmr1:sha384` is writable.
- `rtmr_crypto_agile` demonstrates a "single" MR that supports multiple
hash algorithms. Each supported algorithm has a corresponding digest,
usually referred to as a "bank" in TCG terminology. In this specific
sample, the 2 banks are aliased to `rtmr0` and `rtmr1`, respectively.
- `report_digest` contains the digest of the internal report structure
living in this sample module's memory. It is to demonstrate the use of
the `TSM_MR_F_LIVE` flag. Its value changes each time an RTMR is
extended.

Introduce new TSM Measurement helper library (tsm-mr) for TVM guest drivers
to expose MRs (Measurement Registers) as sysfs attributes, with Crypto
Agility support.
Add the following new APIs (see include/linux/tsm-mr.h for details):
- tsm_mr_create_attribute_group(): Take on input a `struct
tsm_measurements` instance, which includes one `struct
tsm_measurement_register` per MR with properties like `TSM_MR_F_READABLE`
and `TSM_MR_F_WRITABLE`, to determine the supported operations and create
the sysfs attributes accordingly. On success, return a `struct
attribute_group` instance that will typically be included by the guest
driver into `miscdevice.groups` before calling misc_register().
- tsm_mr_free_attribute_group(): Free the memory allocated to the attrubute
group returned by tsm_mr_create_attribute_group().
tsm_mr_create_attribute_group() creates one attribute for each MR, with
names following this pattern:
MRNAME[:HASH]
- MRNAME - Placeholder for the MR name, as specified by
`tsm_measurement_register.mr_name`.
- :HASH - Optional suffix indicating the hash algorithm associated with
this MR, as specified by `tsm_measurement_register.mr_hash`.
Support Crypto Agility by allowing multiple definitions of the same MR
(i.e., with the same `mr_name`) with distinct HASH algorithms.
NOTE: Crypto Agility, introduced in TPM 2.0, allows new hash algorithms to
be introduced without breaking compatibility with applications using older
algorithms. CC architectures may face the same challenge in the future,
needing new hashes for security while retaining compatibility with older
hashes, hence the need for Crypto Agility.

It integrates with the Linux GPIO and watchdog subsystems to provide:
- Control/monitoring of up to 8 EC GPIO pins.
- Hardware watchdog timer with 1-255 second timeouts.
The driver communicates with the EC via I/O port 0xe300 and identifies
the hardware by the "PWG" firmware signature. This enables enhanced

To make the backlight userspace configurable this driver emulates a

corresponding WMI calls. This is a new approach as the leds subsystem lacks
a suitable UAPI for per-key keyboard backlights, and like this no new UAPI
needs to be established.

Merge tag 'soc-fixes-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC fixes from Arnd Bergmann:
"The main changes are once more for the NXP i.MX platform, addressing
multiple regressions in recent devicetree updates for the i.MX8MM and
i.MX6ULL SoCs, a PCIe fix for i.MX9 and a MAINTAINERS file update to
disambiguate NXP i.MX SoCs from Sony IMX image sensors.
The stm32 platform devicetree files get some compatibility fixes for
the interrupt controller node.
Another compatibility fix is done for the Arm Morello platform's cache
controller node.
The code changes are all for firmware drivers, fixing kernel-side bugs
on the Arm FF-A and SCMI drivers"

Triggered by noticing that the pwm-rcar driver isn't covered by the
Renesas maintainer entry, add this driver to it. Instead of adding it
explicitly, just add a file regex for "rcar" (and drop the one entry
that gets redundant by that).
Looking at the output of
$ git ls-files | grep rcar
only shows files related to that architecture, so no X: line is
currently needed.

The zoned loop block device driver allows a user to create emulated
zoned block devices using one regular file per zone as backing storage.
Compared to null_blk or scsi_debug, it has the advantage of allowing
emulating large zoned devices without requiring the same amount of
memory as the capacity of the emulated device. Furthermore, zoned
devices emulated with this driver can be re-started after a host reboot
without any loss of the state of the device zones, which is something
that null_blk and scsi_debug do not support.
This initial implementation is simple and does not support zone resource
limits. That is, a zoned loop block device limits for the maximum number
of open zones and maximum number of active zones is always 0.
This driver can be either compiled in-kernel or as a module, named
"zloop". Compilation of this driver depends on the block layer support
for zoned block device (CONFIG_BLK_DEV_ZONED must be set).
Using the zloop driver to create and delete zoned block devices is
done by writing commands to the zoned loop control character device file
(/dev/zloop-control). Creating a device is done with:
$ echo "add [options]" > /dev/zloop-control
The options available for the "add" operation cat be listed by reading
the zloop-control device file:
$ cat /dev/zloop-control
add id=%d,capacity_mb=%u,zone_size_mb=%u,zone_capacity_mb=%u,conv_zones=%u,base_dir=%s,nr_queues=%u,queue_depth=%u
remove id=%d
The options available allow controlling the zoned device total
capacity, zone size, zone capactity of sequential zones, total number
of conventional zones, base directory for the zones backing file, number
of I/O queues and the maximum queue depth of I/O queues.
Deleting a device is done using the "remove" command:
$ echo "remove id=0" > /dev/zloop-control
This implementation passes various tests using zonefs and fio (t/zbd
tests) and provides a state machine for zone conditions that is
compliant with the T10 ZBC and NVMe ZNS specifications.

In order to achieve a 4 MSPS rate on a 16-bit ADC with a 80 MHz SCLK
using the SPI offload feature of the AXI SPI Engine, we need to shave
off some time that is spent executing unnecessary instructions. There
are a few one-time setup instructions that can be moved so that they
execute only once when the SPI offload trigger is enabled rather than
repeating each time the offload is triggered. Additionally, a recent
change to the IP block allows dropping the SYNC instruction completely.
With these changes, we are left with only the 3 instructions that are
needed to to assert CS, transfer the data, and deassert CS. This makes
3 + 16 * 12.5 ns = 237.5 ns < 250 ns which is comfortably within the
available time period.
The EC of OneXPlayer devices used to only control the fan. This is no
longer the case, with the EC of OneXPlayer gaining additional
functionality (turbo button, turbo led, battery controls).
As it will be beneficial from a complexity perspective to retain this
driver as a single unit, move it out of hwmon, and into platform/x86.
Also, remove the hwmon documentation to prepare moving it to
Documentation/ABI/.
While at it, add myself to the maintainer's file.

Delete the hda_cs_dsp module and move the one array and one function
that is used by the cs35l41_hda driver into that driver.
The cs35l41 and cs35l56 drivers stopped creating ALSA controls to
wrap firmware controls. The reasons are explained in:
commit 312c04cee4 ("ALSA: hda: cs35l41: Stop creating ALSA Controls
for firmware coefficients")
and
commit 34e1b1bb73 ("ALSA: hda: cs35l56: Stop creating ALSA controls
for firmware coefficients")
The cs35l56_hda driver now doesn't use hda_cs_dsp_ctl at all. The
cs35l41_hda driver only uses the small array of firmware names and the
function to read a control value. All other functions and data in
hda_cs_dsp_ctl are unused. There is no need to keep a separate module
for such a small amount of data and code that is only used by one driver,
so remove the whole module.

Pull vfs fixes from Christian Brauner:
- For some reason we went from zero to three maintainers for HFS/HFS+
in a matter of days. The lesson to learn from this might just be that
we need to threaten code removal more often!?
- Fix a regression introduced by enabling large folios for lage logical
block sizes. This has caused issues for noref migration with large
folios due to sleeping while in an atomic context.
New sleeping variants of pagecache lookup helpers are introduced.
These helpers take the folio lock instead of the mapping's private
spinlock. The problematic users are converted to the sleeping
variants and serialize against noref migration. Atomic users will
bail on seeing the new BH_Migrate flag.
This also shrinks the critical region of the mapping's private lock
and the new blocking callers reduce contention on the spinlock for
bdev mappings.
- Fix two bugs in do_move_mount() when with MOVE_MOUNT_BENEATH. The
first bug is using a mountpoint that is located on a mount we're not
holding a reference to. The second bug is putting the mountpoint
after we've called namespace_unlock() as it's no longer guaranteed
that it does stay a mountpoint.
- Remove a pointless call to vfs_getattr_nosec() in the devtmpfs code
just to query i_mode instead of simply querying the inode directly.
This also avoids lifetime issues for the dm code by an earlier bugfix
this cycle that moved bdev_statx() handling into vfs_getattr_nosec().
- Fix AT_FDCWD handling with getname_maybe_null() in the xattr code.
- Fix a performance regression for files when multiple callers issue a
close when it's not the last reference.
- Remove a duplicate noinline annotation from pipe_clear_nowait().

- Sort the included headers.
- Drop sound/tpa6130a2-plat.h because no user is creating the device using
platform data
- Covert to GPIO descriptors
Checking the DTS polarity, all users are using GPIOD_ACTIVE_HIGH.
so all should work as expected with this patch.

The Rockchip RK3576 SoC features a new audio controller, the Serial
Audio Interface, or SAI for short. It is capable of both sending and
receiving audio over up to 4 lanes for each direction using the I2S,
PCM or TDM formats.
This driver is derived from the downstream vendor driver. That is why
its original author, Sugar Zhang, is listed as a Co-developer, with
their signoff. Since adjustments to make the driver suitable for
upstream were quite extensive, I've added myself to the authors and put
myself as the commit author; all added bugs are my fault alone, and not
that of the original author at Rockchip.
The hardware is somewhat similar to the Rockchip I2S-TDM hardware when
judged based on their register map, except it uses the same mclk for
tx and rx. It appears to be much more flexible with regards to TDM.
The loopback stuff and mono mode are new as well.
In line with the changes that were made to the Rockchip I2S-TDM driver
after upstreaming, the mclk-calibrate functionality was dropped, and
setting the mclk rate properly is now left up to the Common Clock
Framework, similar to how it is in the upstream I2S-TDM driver now.
A spinlock has been introduced to protect register write accesses that
depend on the bclk/fs to be stopped, i.e. XFER[1:0] being 0. I couldn't
find whether the asoc core held a per-instance lock so only one callback
can run at a time, and so it seemed prudent to add this.
I couldn't successfully test whether TDM was working, though I've tried
with a TAS6424 codec board. I'm not sure yet whether to blame the codec
driver, this version of the SAI driver, or the vendor implementation of
the SAI driver. The TDM mask registers remain untouched in both this
version and the downstream vendor version, which is suspicious, though
the Linux ASoC core wouldn't be able to support the 128 (!!!) slots of
TDM the hardware supports anyway.
Regular old 2-channel stereo I2S thrown at an I2S stereo codec works
well though. I tested with the CPU-side SAI controller in provider mode
and an Everest ES8388 codec as the consumer.
Some vendor driver features (no-dmaengine, fifo rockchip performance
monitoring, many kcontrols) were dropped for this initial upstream
version. They can always be added later if they make sense for upstream.

I'm currently maintaining the PCI endpoint subsystem and reviewing the
native host bridge and endpoint drivers. However, this affects my endpoint
maintainership role since I cannot merge endpoint patches that depend on
the controller drivers (which is more common). Moreover, the controller
driver patches would also benefit from a helping hand in maintaining them.
So I'd like to step up to maintain the native host bridge and endpoint
drivers together with the endpoint subsystem.

The TI FPC202 dual port controller serves as a low-speed signal aggregator
for common port types such as SFP, QSFP, Mini-SAS HD, and others.
It aggregates GPIO and I2C signals across two downstream ports, acting as
both a GPIO controller and an I2C address translator for up to two logical
devices per port.

The FPC202 dual port controller serves as a low speed signal aggregator for
common port types, notably SFP. It provides access to I2C and low-speed
GPIO signals of a downstream device through a single upstream control
interface.
Up to two logical I2C addresses can be accessed on each of the FPC202's
ports. The port controller acts as an I2C translator (ATR). It converts
addresses of incoming and outgoing I2C transactions. One use case of this
is accessing two SFP modules at logical address 0x50 from the same upstream
I2C controller, using two different client aliases.

Merge series from Andy Shevchenko <andriy.shevchenko@linux.intel.com>:
Recently in the discussion with David the idea of having
a common helper popped up. The helper converts the given
bits per word to bytes. The result will always be power-of-two
(e.g. for 37 bits it returns 8 bytes) or 0 for 0 input.
More details are in the respective code comment.
This mini-series introduces it and replaces current users
under drivers/spi and we expect more (and possibly some
lurking in other subsystems).
We place this under memory mapping as related to memory mapping
abstractions in the form of mm_struct and vm_area_struct (VMA). Now we
have separated out mmap/vma locking logic into the mmap_lock.c and
mmap_lock.h files, so this should encapsulate the majority of the mm
locking logic in the kernel.
Suren is best placed to maintain this logic as the core architect of VMA
locking as a whole.

The ovpn-cli tool can be compiled and used as selftest for the ovpn
kernel module.
[NOTE: it depends on libmedtls for decoding base64-encoded keys]
ovpn-cli implements the netlink and RTNL APIs and can thus be integrated
in any script for more automated testing.
Along with the tool, a bunch of scripts are provided that perform basic
functionality tests by means of network namespaces.
These scripts take part to the kselftest automation.
The output of the scripts, which will appear in the kselftest
reports, is a list of steps performed by the scripts plus some
output coming from the execution of `ping`, `iperf` and `ovpn-cli`
itself.
In general it is useful only in case of failure, in order to
understand which step has failed and why.
Please note: since peer sockets are tied to the userspace
process that created them (i.e. exiting the process will result
in closing the socket), every run of ovpn-cli that created
one will go to background and enter pause(), waiting for the
signal which will allow it to terminate.
Termination is accomplished at the end of each script by
issuing a killall command.

OpenVPN is a userspace software existing since around 2005 that allows
users to create secure tunnels.
So far OpenVPN has implemented all operations in userspace, which
implies several back and forth between kernel and user land in order to
process packets (encapsulate/decapsulate, encrypt/decrypt, rerouting..).
With `ovpn` we intend to move the fast path (data channel) entirely
in kernel space and thus improve user measured throughput over the
tunnel.
`ovpn` is implemented as a simple virtual network device driver, that
can be manipulated by means of the standard RTNL APIs. A device of kind
`ovpn` allows only IPv4/6 traffic and can be of type:
* P2P (peer-to-peer): any packet sent over the interface will be
encapsulated and transmitted to the other side (typical OpenVPN
client or peer-to-peer behaviour);
* P2MP (point-to-multipoint): packets sent over the interface are
transmitted to peers based on existing routes (typical OpenVPN
server behaviour).
After the interface has been created, OpenVPN in userspace can
configure it using a new Netlink API. Specifically it is possible
to manage peers and their keys.
The OpenVPN control channel is multiplexed over the same transport
socket by means of OP codes. Anything that is not DATA_V2 (OpenVPN
OP code for data traffic) is sent to userspace and handled there.
This way the `ovpn` codebase is kept as compact as possible while
focusing on handling data traffic only (fast path).
Any OpenVPN control feature (like cipher negotiation, TLS handshake,
rekeying, etc.) is still fully handled by the userspace process.
When userspace establishes a new connection with a peer, it first
performs the handshake and then passes the socket to the `ovpn` kernel
module, which takes ownership. From this moment on `ovpn` will handle
data traffic for the new peer.
When control packets are received on the link, they are forwarded to
userspace through the same transport socket they were received on, as
userspace is still listening to them.
Some events (like peer deletion) are sent to a Netlink multicast group.
Although it wasn't easy to convince the community, `ovpn` implements
only a limited number of the data-channel features supported by the
userspace program.
Each feature that made it to `ovpn` was attentively vetted to
avoid carrying too much legacy along with us (and to give a clear cut to
old and probalby-not-so-useful features).
Notably, only encryption using AEAD ciphers (specifically
ChaCha20Poly1305 and AES-GCM) was implemented. Supporting any other
cipher out there was not deemed useful.
Both UDP and TCP sockets are supported.
As explained above, in case of P2MP mode, OpenVPN will use the main system
routing table to decide which packet goes to which peer. This implies
that no routing table was re-implemented in the `ovpn` kernel module.
This kernel module can be enabled by selecting the CONFIG_OVPN entry
in the networking drivers section.
NOTE: this first patch introduces the very basic framework only.
Features are then added patch by patch, however, although each patch
will compile and possibly not break at runtime, only after having
applied the full set it is expected to see the ovpn module fully working.

Add dma_alloc_attrs() and dma_free_attrs() helpers to fix a build
error when CONFIG_HAS_DMA is not enabled.
Note that when CONFIG_HAS_DMA is enabled, dma_alloc_attrs() and
dma_free_attrs() are included in both bindings_generated.rs and
bindings_helpers_generated.rs. The former takes precedence so behavior
remains unchanged in that case.
This fixes the following build error on UML:

Specifically list various Cirrus Logic and Wolfson Micro codec header files
under include/sound/ within the ASoC section of MAINTAINERS. Note that not
all the include/sound/cs* files are part of ASoC, so more-specific patterns
are needed.
These files are all part of ASoC codec drivers, and are owned by specific
Cirrus Logic and Wolfson Micro sections of MAINTAINERS. But the overall
include/sound/* maintainership is only Takashi Iwai and Jaroslav Kysela.
So by default get_maintainer.pl would only show Takashi and Jaroslav as
maintainers for any patch that changes these files without changing any
code under sound/soc.
There is a separate MAINTAINERS section for ASoC, so the headers must be
added there to make the ASoC maintainers show up in get_maintainer.pl.

DCCP was orphaned in 2021 by commit 054c4610bd ("MAINTAINERS: dccp:
move Gerrit Renker to CREDITS"), which noted that the last maintainer
had been inactive for five years.
In recent years, it has become a playground for syzbot, and most changes
to DCCP have been odd bug fixes triggered by syzbot. Apart from that,
the only changes have been driven by treewide or networking API updates
or adjustments related to TCP.
Thus, in 2023, we announced we would remove DCCP in 2025 via commit
b144fcaf46 ("dccp: Print deprecation notice.").
Since then, only one individual has contacted the netdev mailing list. [0]
There is ongoing research for Multipath DCCP. The repository is hosted
on GitHub [1], and development is not taking place through the upstream
community. While the repository is published under the GPLv2 license,
the scheduling part remains proprietary, with a LICENSE file [2] stating:
"This is not Open Source software."
The researcher mentioned a plan to address the licensing issue, upstream
the patches, and step up as a maintainer, but there has been no further
communication since then.
Maintaining DCCP for a decade without any real users has become a burden.
Therefore, it's time to remove it.
Removing DCCP will also provide significant benefits to TCP. It allows
us to freely reorganize the layout of struct inet_connection_sock, which
is currently shared with DCCP, and optimize it to reduce the number of
cachelines accessed in the TCP fast path.
Note that we keep DCCP netfilter modules as requested. [3]
