Pull drm updates from Dave Airlie:
"The biggest highlight is that the accel subsystem framework is merged.
Hopefully for 6.3 we will be able to line up a driver to use it.
In drivers land, i915 enables DG2 support by default now, and nouveau
has a big stability refactoring and initial ampere support, AMD
includes new hw IP support and should build on ARM again. There is
also an ofdrm driver to take over offb on platforms it's used.
Stuff outside my tree, the dma-buf patches hit a few places, the vc4
firmware changes also do, and i915 has some interactions with MEI for
discrete GPUs. I think all of those should have been acked/reviewed by
relevant parties.

Pull io_uring updates from Jens Axboe:
- Always ensure proper ordering in case of CQ ring overflow, which then
means we can remove some work-arounds for that (Dylan)
- Support completion batching for multishot, greatly increasing the
efficiency for those (Dylan)
- Flag epoll/eventfd wakeups done from io_uring, so that we can easily
tell if we're recursing into io_uring again.
Previously, this would have resulted in repeated multishot
notifications if we had a dependency there. That could happen if an
eventfd was registered as the ring eventfd, and we multishot polled
for events on it. Or if an io_uring fd was added to epoll, and
io_uring had a multishot request for the epoll fd.
Test cases here:
https://git.kernel.dk/cgit/liburing/commit/?id=919755a7d0096fda08fb6d65ac54ad8d0fe027cd
Previously these got terminated when the CQ ring eventually
overflowed, now it's handled gracefully (me).

- Optimizations of the networking zero-copy paths (Pavel)

Pull landlock updates from Mickaël Salaün:
"This adds file truncation support to Landlock, contributed by Günther
Noack. As described by Günther [1], the goal of these patches is to
work towards a more complete coverage of file system operations that
are restrictable with Landlock.
The known set of currently unsupported file system operations in
Landlock is described at [2]. Out of the operations listed there,
truncate is the only one that modifies file contents, so these patches
should make it possible to prevent the direct modification of file
contents with Landlock.
The new LANDLOCK_ACCESS_FS_TRUNCATE access right covers both the
truncate(2) and ftruncate(2) families of syscalls, as well as open(2)
with the O_TRUNC flag. This includes usages of creat() in the case
where existing regular files are overwritten.
Additionally, this introduces a new Landlock security blob associated
with opened files, to track the available Landlock access rights at
the time of opening the file. This is in line with Unix's general
approach of checking the read and write permissions during open(), and
associating this previously checked authorization with the opened
file. An ongoing patch documents this use case [3].
In order to treat truncate(2) and ftruncate(2) calls differently in an
LSM hook, we split apart the existing security_path_truncate hook into
security_path_truncate (for truncation by path) and
security_file_truncate (for truncation of previously opened files)"

Pull btrfs updates from David Sterba:
"This round there are a lot of cleanups and moved code so the diffstat
looks huge, otherwise there are some nice performance improvements and
an update to raid56 reliability.
User visible features:
- raid56 reliability vs performance trade off:
- fix destructive RMW for raid5 data (raid6 still needs work): do
full checksum verification for all data during RMW cycle, this
should prevent rewriting potentially corrupted data without
notice
- stripes are cached in memory which should reduce the performance
impact but still can hurt some workloads
- checksums are verified after repair again
- this is the last option without introducing additional features
(write intent bitmap, journal, another tree), the extra checksum
read/verification was supposed to be avoided by the original
implementation exactly for performance reasons but that caused
all the reliability problems
- discard=async by default for devices that support it
- implement emergency flush reserve to avoid almost all unnecessary
transaction aborts due to ENOSPC in cases where there are too many
delayed refs or delayed allocation
- skip block group synchronization if there's no change in used
bytes, can reduce transaction commit count for some workloads
Performance improvements:
- fiemap and lseek:
- overall speedup due to skipping unnecessary or duplicate
searches (-40% run time)
- cache some data structures and sharedness of extents (-30% run
time)
- send:
- faster backref resolution when finding clones
- cached leaf to root mapping for faster backref walking
- improved clone/sharing detection
- overall run time improvements (-70%)
Core:
- module initialization converted to a table of function pointers run
in a sequence
- preparation for fscrypt, extend passing file names across calls,
dir item can store encryption status
- raid56 updates:
- more accurate error tracking of sectors within stripe
- simplify recovery path and remove dedicated endio worker kthread
- simplify scrub call paths
- refactoring to support the extra data checksum verification
during RMW cycle
- tree block parentness checks consolidated and done at metadata read
time
- improved error handling
- cleanups:
- move a lot of code for better synchronization between kernel and
user space sources, split big files
- enum cleanups
- GFP flag cleanups
- header file cleanups, prototypes, dependencies
- redundant parameter cleanups
- inline extent handling simplifications
- inode parameter conversion
- data structure cleanups, reductions, renames, merges"

Zhang. SM4 is a Chinese block cipher that is an alternative to AES.
I recommend against using SM4, but (according to Tianjia) some people

other places (crypto API, wireless, TLS, OpenSSL, ARMv8 CPUs, etc.),
it hasn't been very controversial, and some people have to use it, I
don't think it would be fair for me to reject this optional feature.

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for 6.2.
While it may seem backwards, the CXL update this time around includes
some focus on CXL 1.x enabling where the work to date had been with
CXL 2.0 (VH topologies) in mind.
First generation CXL can mostly be supported via BIOS, similar to DDR,
however it became clear there are use cases for OS native CXL error
handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
hosts (Restricted CXL Host (RCH) topologies). So, this update brings
RCH topologies into the Linux CXL device model.
In support of the ongoing CXL 2.0+ enabling two new core kernel
facilities are added.
One is the ability for the kernel to flag collisions between userspace
access to PCI configuration registers and kernel accesses. This is
brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
mailbox over config-cycles.
The other is a cpu_cache_invalidate_memregion() API that maps to
wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
VMs and architectures that do not support it yet. The CXL paths that
need it, dynamic memory region creation and security commands (erase /
unlock), are disabled when it is not present.
As for the CXL 2.0+ this cycle the subsystem gains support Persistent
Memory Security commands, error handling in response to PCIe AER
notifications, and support for the "XOR" host bridge interleave
algorithm.
Summary:
- Add the cpu_cache_invalidate_memregion() API for cache flushing in
response to physical memory reconfiguration, or memory-side data
invalidation from operations like secure erase or memory-device
unlock.
- Add a facility for the kernel to warn about collisions between
kernel and userspace access to PCI configuration registers
- Add support for Restricted CXL Host (RCH) topologies (formerly CXL
1.1)
- Add handling and reporting of CXL errors reported via the PCIe AER
mechanism
- Add support for CXL Persistent Memory Security commands
- Add support for the "XOR" algorithm for CXL host bridge interleave
- Rework / simplify CXL to NVDIMM interactions
- Miscellaneous cleanups and fixes"

Usually when closing a crypto device (eg: dm-crypt with LUKS) the
volume key is not required, as it requires root privileges anyway, and
root can deny access to a disk in many ways regardless. Requiring the
volume key to lock the device is a peculiarity of the OPAL
specification.
Given we might already have saved the key if the user requested it via
the 'IOC_OPAL_SAVE' ioctl, we can use that key to lock the device if no
key was provided here and the locking range matches, and the user sets
the appropriate flag with 'IOC_OPAL_SAVE'. This allows integrating OPAL
with tools and libraries that are used to the common behaviour and do
not ask for the volume key when closing a device.
Callers can always pass a non-zero key and it will be used regardless,
as before.

CXL PMEM security operations are routed through the NVDIMM sysfs
interface. For this reason the corresponding commands are marked
"exclusive" to preclude collisions between the ioctl ABI and the sysfs
ABI. However, a better way to preclude that collision is to simply
remove the ioctl ABI (command-id definitions) for those operations.
Now that cxl_internal_send_cmd() (formerly cxl_mbox_send_cmd()) no
longer needs to talk the cxl_mem_commands array, all of the uapi
definitions for the security commands can be dropped.
These never appeared in a released kernel, so no regression risk.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v6.2
This is a fairly sedate release for the core code, but there's been a
lot of driver work especially around the x86 platforms and device tree
updates:
- More cleanups of the DAPM code from Morimoto-san.
- Factoring out of mapping hw_params onto SoundWire configuration by
Charles Keepax.
- The ever ongoing overhauls of the Intel DSP code continue, including
support for loading libraries and probes with IPC4 on SOF.
- Support for more sample formats on JZ4740.
- Lots of device tree conversions and fixups.
- Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
Rockchip RK3588
There's more cross tree updates than usual, though all fairly minor:
- Some OMAP board file updates that were depedencies for removing their
providers in ASoC, as part of a wider effort removing the support for
the relevant OMAP platforms.
- A new I2C API required for updates to the new I2C probe API.
- A DRM update making use of a new API for fixing the capabilities
advertised via hdmi-codec.
Since this is being sent early I might send some more stuff if you've
not yet sent your pull request and there's more come in.

For directories with encrypted files/filenames, we need to store a flag
indicating this fact. There's no room in other fields, so we'll need to
borrow a bit from dir_type. Since it's now a combination of type and
flags, we rename it to dir_flags to reflect its new usage.
The new flag, FT_ENCRYPTED, indicates a directory containing encrypted
data, which is orthogonal to file type; therefore, add the new
flag, and make conversion from directory type to file type strip the
flag.
As the file types almost never change we can afford to use the bits.
Actual usage will be guarded behind an incompat bit, this patch only
adds the support for later use by fscrypt.

Merge series from Mark Brown <broonie@kernel.org>:
The recently added pcm-test selftest has pointed out that systems with
the tda998x driver end up advertising that they support capture when in
reality as far as I can see the tda998x devices are transmit only. The
DAIs registered through hdmi-codec are bidirectional, meaning that for
I2S systems when combined with a typical bidrectional CPU DAI the
overall capability of the PCM is bidirectional. In most cases the I2S
links will clock OK but no useful audio will be returned which isn't so
bad but we should still not advertise the useless capability, and some
systems may notice problems for example due to pinmux management.
This is happening due to the hdmi-codec helpers not providing any
mechanism for indicating unidirectional audio so add one and use it in
the tda998x driver. It is likely other hdmi-codec users are also
affected but I don't have those systems to hand.

These old unused definitions were originally left around to prevent the
same mode numbers from being reused. However, we've now decided to
reuse the mode numbers anyway. So let's completely remove these old
unused definitions to avoid confusion. There is no reason for any code
to be using these constants in any way; and indeed, Debian Code Search
shows no uses of them (other than in copies or translations of the
header). So this should be perfectly safe.

by the DVB-C2 (ETSI EN 302 769) and DVB-S2X (ETSI EN 302 307-2)
standards to be ready for frontend drivers for such receivers.
While most parameters will be "read-only" due to being autodetected by
the receiver and only being reported back for informational purposes,
the addition of SYS_DVBC2 to the delivery systems enum is required,
because there are DVB-C2 capable receivers which are not capable of
DVB-C/C2 autodetection and thus need this enum value to be explicitly
instructed to search for a DVB-C2 signal.
As for DVB-S2X, as that is an extension to DVB-S2, the same delivery
system enum as for DVB-S2 can be used.
Add the additional enum values and comments to the documentation.

In general, as of now, in FUSE, direct writes on the same file are
serialized over inode lock i.e we hold inode lock for the full duration of
the write request. I could not find in fuse code and git history a comment
which clearly explains why this exclusive lock is taken for direct writes.
Following might be the reasons for acquiring an exclusive lock but not be
limited to
1) Our guess is some USER space fuse implementations might be relying on
this lock for serialization.
2) The lock protects against file read/write size races.
3) Ruling out any issues arising from partial write failures.
This patch relaxes the exclusive lock for direct non-extending writes only.
File size extending writes might not need the lock either, but we are not
entirely sure if there is a risk to introduce any kind of regression.
Furthermore, benchmarking with fio does not show a difference between patch
versions that take on file size extension a) an exclusive lock and b) a
shared lock.
A possible example of an issue with i_size extending writes are write error
cases. Some writes might succeed and others might fail for file system
internal reasons - for example ENOSPACE. With parallel file size extending
writes it _might_ be difficult to revert the action of the failing write,
especially to restore the right i_size.
With these changes, we allow non-extending parallel direct writes on the
same file with the help of a flag called FOPEN_PARALLEL_DIRECT_WRITES. If
this flag is set on the file (flag is passed from libfuse to fuse kernel as
part of file open/create), we do not take exclusive lock anymore, but
instead use a shared lock that allows non-extending writes to run in
parallel. FUSE implementations which rely on this inode lock for
serialization can continue to do so and serialized direct writes are still
the default. Implementations that do not do write serialization need to be
updated and need to set the FOPEN_PARALLEL_DIRECT_WRITES flag in their file
open/create reply.
On patch review there were concerns that network file systems (or vfs
multiple mounts of the same file system) might have issues with parallel
writes. We believe this is not the case, as this is just a local lock,
which network file systems could not rely on anyway. I.e. this lock is
just for local consistency.

Add a flag to entry expiration that lets the filesystem expire a dentry
without kicking it out from the cache immediately.
This makes a difference for overmounted dentries, where plain invalidation
would detach all submounts before dropping the dentry from the cache. If
only expiry is set on the dentry, then any overmounts are left alone and
until ->d_revalidate() is called.
Note: ->d_revalidate() is not called for the case of following a submount,
so invalidation will only be triggered for the non-overmounted case. The
dentry could also be mounted in a different mount instance, in which case
any submounts will still be detached.

HUTRR72 added 3 new usage codes for keys that are supposed to enable,
disable and toggle camera access. These are useful, considering many
laptops today have key(s) for toggling access to camera.
This patch adds new key definitions for KEY_CAMERA_ACCESS_ENABLE,
KEY_CAMERA_ACCESS_DISABLE and KEY_CAMERA_ACCESS_TOGGLE. Additionally
hid-debug is adjusted to recognize this new usage codes as well.

We can have dependencies between epoll and io_uring. Consider an epoll
context, identified by the epfd file descriptor, and an io_uring file
descriptor identified by iofd. If we add iofd to the epfd context, and
arm a multishot poll request for epfd with iofd, then the multishot
poll request will repeatedly trigger and generate events until terminated
by CQ ring overflow. This isn't a desired behavior.
Add EPOLL_URING so that io_uring can pass it in as part of the poll wakeup
key, and io_uring can check for that to detect a potential recursive
invocation.

It might be useful for applications to detect if a zero copy transfer with
SEND[MSG]_ZC was actually possible or not. The application can fallback to
plain SEND[MSG] in order to avoid the overhead of two cqes per request. Or
it can generate a log message that could indicate to an administrator that
no zero copy was possible and could explain degraded performance.

TDX guest driver exposes IOCTL interfaces to service TDX guest
user-specific requests. Currently, it is only used to allow the user to
get the TDREPORT to support TDX attestation.
Details about the TDX attestation process are documented in
Documentation/x86/tdx.rst, and the IOCTL details are documented in
Documentation/virt/coco/tdx-guest.rst.
Operations like getting TDREPORT involves sending a blob of data as
input and getting another blob of data as output. It was considered
to use a sysfs interface for this, but it doesn't fit well into the
standard sysfs model for configuring values. It would be possible to
do read/write on files, but it would need multiple file descriptors,
which would be somewhat messy. IOCTLs seem to be the best fitting
and simplest model for this use case. The AMD sev-guest driver also
uses the IOCTL interface to support attestation.

This is because we try to copy the whole ip/ip6 address to the flow_key,
while we only point the to ip/ip6 saddr. Note that since these are UAPI
