Pull spi updates from Mark Brown:
"Along with a lot of driver specific work we've got a couple of core
features here. The bigger one is that we've now got support for
instantiating devices from sysfs similarly to how it's already done
for I2C, this is used with development boards with non-enumerable
expansion headers since SPI devices need to be manually specified. We
also have support for the DQS signal on higher end flash devices.
- Support for instantiating devices from sysfs, useful for
development boards with non-enumerable plugin modules, from
Vishwaroop A.
- Support for DQS in spi-mem, an additional signal used by flash
devices to avoid clock skew from Miquel Raynal.
- Support for more advanced SPI modes on DesignWare controllers from
Sudip Mukherjee.
- Changes from Jisheng Zhang to update to modern methods of
specifying the PM callbacks.
- Fixes for DMA mapping error handling, plus KUnit tests for this,
from Honghui Jiang.
- Substantial cleanup and performance work in the nxp-spi driver.
- Support for Microchip LAN969x, Nuvoton MA35D1 QSPI, Qualcomm
SA8255p and SA8797P, and StarFive JHB100 SFC"

Currently NVMe fault injection applies to every command routed through
nvme_should_fail(), which makes it hard to target a specific command
type when reproducing an issue in error-handling paths.
Add an "opcode" debugfs attribute alongside the existing "status" and
"dont_retry" knobs. It defaults to 0xffff, meaning "match any opcode"
and preserving the previous behavior. When set to a valid opcode
(<= 0xff), fault injection is only considered for commands whose opcode
matches.

over SPI
- Add support for AD5316R, AD5674, AD5697R and AD5696 DACs over I2C
- Significant driver refactoring prior to these additions, partly to reduce
bus traffic and to add triggered buffer and gain control support. An
earlier set added support for missing supplies, reset and LDAC GPIO.

- New driver to support this PLL frequency synthesizer that runs up to
26.5 GHz.
- Included infrastructure to handle higher precision attributes with
extensive tests
adi,ltc2378-20

LTC2376, LTC2377, LTC2378, LTC2379 and LTC23980 ADCs with both high speed
capture via appropriate backend and conventional triggered buffer SPI
capture.
invensense,icm42607
- New driver for this IMU.
mediateck,mt6323
- New driver for this PMIC ADC.
microchip,mcp47a1

- Support buffered reads.
ti,tmp117
- (trivial) Add support for the tmp119 temperature sensor.
xilinx,versal-sysmon

specification of currents used for resistive sensor measurement.
- reference-sources property to allow selection of a per channel reference.
rockchip,saradc

Cleanups, minor fixes
---------------------
Minor cleanups not mentioned at all in this summary such
as white space fixes or typos.
Affecting various drivers
- Cleanup of conditionals that had no affect.
- Drop some runtime pm local wrappers as now runtime_pm does the
mark_last_busy part inside the put, these provide no useful code
deduplication or readability advantages over directly calling the
runtime_pm functions.
- Return 0 from write_raw() on success.
- Use of dev_err_probe() to simplify code and sometimes provide useful
info for deferred probe debugging.
- Drop some redundant error prints where the called function already
provides information on errors.
- Make some read only arrays in functions static.
- Fix up missing handling of regcache_sync() errors.
- Drop some false kernel-doc markings.
- Add missing MODULE_DEVICE_TABLE for some of_match_id tables.
- Use local variables for things like the struct device to shorten and
improve readability of code.
- Drop some unused structure elements.
- Reorder dds.h macro parameters to be inline with others.
- Header reorders and IWYU. Often part of a more significant series.
- Remove abstractions designed to allow a driver to support multiple device
types, when they have been around a long time and only the original part
showed up.
- Initialize spi_device_id arrays using member names following dropping of
driver data from drivers that didn't actually use it.
- Catch up with i2c_device_id tables added since previous effort to use
named initializers for all those.
- Use kernel types in a few places instead of standard C ones or bare
unsigned.
Misc
- Update Xilinx AMS maintainer.
- Update email address for Maxwell Doose.
- Update email address for Siratul Islam.

flexibility in input to differential pair mapping. Intended to
provide a strong signal to userspace that a channel is differential.
adi,ad_sigma_delta
- Allow COMPILE_TEST without any users.
adi,ad2s1201
- Refactor trigger handler to avoid mix of guard() and goto.
adi,ad5686

On platform specific drivers, this includes SoC specific code for
xilinx, freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung,
rockchip, renesas, ixp4xx. In firmware drivers, we see a similar
picture for SCMI and qcomtee.
Aside from these, we see actual new hardware support in a few areas:
- The Apple platform gets a new driver for low power states
- Updates to Qualcomm platform drivers add several new hardware
specific features and additional SoCs.
- Amlogic SoC support for A1 and T7 is added
- The Mediatek MMSYS driver is refactored as a cleanup"

Pull SoC devicetree updates from Arnd Bergmann:
"There are two new mystery SoCs with very little public information
about them so far, Qualcomm's Cortex-A78C based "Shikra" and Altera's
Cortex-A720 based Agilex72 SOCFPGA.
We have also gained support for a couple of SoCs from the 2023/2024
timeframe that have been in the making for a while:
- The Apple platform gains support for M3 Pro, Max and Ultra SoC,
following the basic M3 support from 7.2.
- Samsung Exynos 1580 is a high-end mobile phone SoC from 2024
- Canaan K230 is a RISC-V based 64-bit AI SoC, based on the earlier
K210 chip
- Sophgo SG2000 is a mixed Arm/RISC-V chip that was already supported
using the Arm core but is now also added for RISC-V along with
several other variants of the cv18xx series
In terms of newly added machines we have reference platforms for all
the chips above, plus
- Only four 32-bit Arm boards: two older phones and two older
industrial/embedded boards; using Allwinner, Qualcomm and Rockchip
SoCs
- Three laptops und three phones using Qualcomm SoCs
- Ten 64-bit Rockchips based single-board computers, along with one
NAS box and a game console.
- Seven industrial/embedded boards and modules using NXP i.MX8/9
SoCs.
- A Lenovo desktop box based on NVIDIA Jetson Xavier NX
- A few more single-board computers based on Allwinnner A133,
Spacemit K1 and TI AM62.
As usual, there is a constant stream of minor cleanups and fixes
towards addressing the 'dt-check-style --mode strict' warnings, and
everyone is expected to address those warnings for new submissions
now"

Pull generic entry code updates from Thomas Gleixner:
- Make syscall user dispatching configurable
Not all architectures can makes use of syscall user dispatching.
Allow them to disable the feature completely.
- Consolidate stack randomization for the generic entry code and the
architectures using it.
Stack randomization on syscall entry was sprinkled throughout the
architecture specific low level entry code and in some cases at the
wrong points, e.g. before establishing state, which violates the
non-instrumentable constraints of that code.
Clean this up by integrating stack randomization into the generic
entry code helpers so that it is invoked at the earliest possible
point right after establishing state and converting all generic entry
code using architecture over.
- Clean up the syscall number handling in the generic entry code. It
works correctly for architectures which have a separate return value
storage in pt_regs, but fails to distinguish the case where user
space handed in -1 as syscall number from the case where the entry
code rejects it by returning -1 to the callers. Aside of that the
return value functionality of those interfaces is not really
intuitive.
Fix this by separating the decision to reject a syscall (user
dispatch, ptrace, seccomp ...) from the potential modification of the
syscall number through these mechanisms.
This solves most of the problems for architectures which do not have
a separate return value storage in pt_regs except for the case where
a tracepoint has a BPF script or a probe attached which overwrite
both the syscall number and the return value. But that's a problem
which cannot be solved in the generic code, that only can be
addressed by separating the storage model in the affected
architectures.

'rustc-dev' component is installed, which was uncovered by the work
to support Rust's GCC backend ('rustc_codegen_gcc')
- Fix future Clang warnings in the upcoming powerpc support due to
macro redefinitions in the UAPI helper header by including the
arch-aware 'ioctl.h' header
'kernel' crate:
- Rework module ownership support:
- Move the module-related types into a new 'module' module and
make the 'THIS_MODULE' pointer a constant of 'ModuleMetadata'
so that modules can provide the pointer in const contexts, and
add a 'this_module' 'const fn' to retrieve it
This was enabled by upstream Rust's work on the 'const_mut_refs'
and 'const_refs_to_static' features which were stabilized back
in Rust 1.83.0
- Teach '#[vtable]' to associate implementations with their
owning module, defaulting to the local one, including fallbacks
for doctests, uses within the 'kernel' crate (like upcoming
KUnit '#[test]'s for DRM) and 'rusttest'
- Set 'fops.owner' from the module pointer for DRM and
miscdevice
- Migrate Rust Binder and configfs away from the old
'THIS_MODULE' 'static' and finally remove it from the 'module!'
macro
- 'num' module:
- Add the new 'casts' module for lossless integer conversions
Rust's 'core' library's 'From' implementations do not cover
conversions that are not portable or future-proof. However, the
kernel supports a narrower set of architectures, which makes it
helpful to provide more infallible conversions, instead of
having developers use 'as' casts, which carry the risk of
silently losing data
This goes along with previous work we did to avoid casts in
Rust kernel code since they are more powerful than needed
Thus, provide safe 'const' conversion functions (e.g.
'usize_as_u64' and 'u64_into_u8'), as well as the
'FromSafeCast' and 'IntoSafeCast' extension traits that provide
conversions that are known to be lossless in the kernel, and an
'arch' submodule defining conversions that are known to be
lossless on particular architectures (e.g. 64-bit platforms).
For instance:
// Conversion in const context.
const USIZED_CONST: usize = u8_as_usize(255u8);
// Non-const conversions.
let a = u64::from_safe_cast(4096usize);
let b: u64 = 4096usize.into_safe_cast();
- Add 'Bounded::shr_exact' method in the vein of 'try_shrink'
which shifts a bounded right only if it loses no set bits
- Fix unsoundness issue in the 'Bounded::shr' method by
rejecting, at compile-time, shifts of at least the type's bit
width
- 'fmt' module:
- Route '{:p}' raw pointer formatting through the kernel's hashed
'%p' format to prevent address leaks, including support for
width and padding. Include tests for both 'no_hash_pointers'
case and the default (hashed) one
- Fix the '{:p}' forwarding implementation, which could print the
address of a temporary stack variable
- 'time' module:
- Make 'Delta' generic over its time unit, with a default unit of
nanoseconds ('Nsec'), preserving the existing behavior. Then,
add a 'Jiffy' time unit
- Add the 'Delta::as_millis_ceil()' method
- Fix 'as_micros_ceil()' rounding near 'i64::MAX', which could
yield a result one microsecond too small
- 'sync' module:
- Implement 'ForeignOwnable' for 'ARef<T>', allowing C code to
own an 'ARef<T>'
- Add a safe abstraction for 'rcu_barrier()'
- 'error' module: add all of the remaining error codes, except the
deprecated compatibility aliases
- 'bug' module:
- Fix build error on UML in 'warn_on!' for callers from within
the 'kernel' crate
- Fix future 'dead_code' warning on arm and loongarch64 and under
'CONFIG_BUG=n' in 'warn_on!', which would trigger with the
upcoming SRCU abstractions
- Fix future build error in 'rusttest' on cross-compilation
cases, which would trigger when 'warn_on!' has callers inside
the 'kernel' crate
- 'bitfield' module: fix build error for the upcoming support for
Rust's GCC backend ('rustc_codegen_gcc') by always inlining a
couple conversions used in tests
'pin-init' crate:
- User-visible changes:
- Merge the '__pinned_init' and '__init' methods and make 'Init'
a marker trait
- Introduce public APIs 'raw_init' and 'raw_try_init' to prevent
users from needing to invoke the internal '__pinned_init' and
'__init' methods
- Emit errors for duplicate '#[pin]' attributes
- Link 'Zeroable::zeroed' and 'pin_init::zeroed' in documentation
- Other changes:
- Fix unwind safety issues
- Clean up lint 'allow' and 'expect's
- Overhaul '#[cfg]' handling to pave the way for tuple structs
and self-referential structs
- Mark many functions as '#[inline]' for better codegen with '-C
opt-level=s' ('CC_OPTIMIZE_FOR_SIZE')
'MAINTAINERS':
- Update 'MODULE SUPPORT' to cover the new 'module' module
And some other fixes, cleanups and improvements"

Pull ACPI support updates from Rafael Wysocki:
"The most significant change here is the elimination of struct
acpi_driver that has no more users in the tree now along with some
documentation related to it, and a follow-up update to set the "no PM"
flag for all ACPI devices that are now only going to play the role of
other devices' "companions" (in analogy with DT nodes).
There is also a significant update of irqchip code related to ACPI
done in order to enable GICv5 IWB ACPI probe ordering detection on
ARM, which involves RISC-V interrupt controller management code
refactoring to extract generic code from it into the common ACPI IRQ
code.
The rest is mostly fixes, including some fallout of the _OSC handling
rework in 7.0, ACPI CPPC library fixes, a workaround for registering
ACPI platform devices with overlapping I/O or memory resources, an
ACPI EC driver fix related to probe deferral on platforms using
HW-reduced ACPI, two ACPI battery driver fixes and a workaround for
handling model numbers with unprintable characters in it, probe error
cleanup and driver unload code path fixes, hardware error reporting
fixes, documentation fixes, and assorted code cleanups all over.
Specifics:
- Eliminate struct acpi_driver whose users have all been converted to
bind to platform devices or auxiliary devices and set the "no power
management" flag for all struct acpi_device objects (Rafael
Wysocki)
- Avoid complaints regarding missing _OSC features on platforms where
OSC_CAPABILITIES_MASK_ERROR is set in _OSC error bits even though
all of the requested features are actually acknowledged (Rafael
Wysocki)
- Avoid printing confusing _OSC messages for non-PCIe host bridges
without _OSC which is a valid configuration (Kazuma Kondo)
- Use correct region struct for BERT region size check and properly
map BERT and CCEL data to their ACPI tables (Thomas Renninger)
- Add acpi_device_clear_deps(), refactor RISC-V interrupt controller
management code to extract generic code from it into the common
ACPI IRQ code, and enable GICv5 IWB ACPI probe ordering detection
on ARM on top of that (Lorenzo Pieralisi)
- Stop using acpi_device_name() in the PNP core, stop setting
acpi_device_name/class() in the Xen variant of the ACPI PAD
(Processor Aggregator Device) driver, and make the Loongarch laptop
driver stop setting acpi_device_class() (Rafael Wysocki)
- Fix issues related to the desired_perf register access in the ACPI
CPPC library and update it to avoid unnecessary overhead (Christian
Loehle)
- Simplify acpi_get_pci_dev() with the help of a mutex guard,
introduce acpi_dev_get_pci_dev() for code that has a struct ACPI
device for which it wants to get the struct pci_dev pointer of the
associated PCI device, and use it in the ACPI video bus driver
(Rafael Wysocki)
- Avoid registering platform devices with resource overlaps in the
ACPI core device enumeration code (Rafael Wysocki)
- Clean up the list of included header files in the NHLT table parser
and validate the table and record lengths in the FPDT parser (Andy
Shevchenko and Pengpeng Hou)

code to use correct struct member names to avoid warnings (Randy
Dunlap)

driver (Randy Dunlap)
- Update ACPI fan IDs to follow modern style and clean up header file
inclusions in the ACPI fan driver (Andy Shevchenko)
- Use devm_acpi_install_notify_handler() to replace a custom
open-coded devres-based management of an ACPI notify handler in the
ACPI fan driver (Rafael Wysocki)
- Adjust charging status validation check in the ACPI battery driver
to avoid incorrect status reporting (Rafael Wysocki)
- Merge consecutive battery notifications in the ACPI battery driver
to reduce the pressure on STA, _BST and _BIX/_BIF ACPI control
methods and make that driver use kstrtoul() instead of
sscanf("%lu\n") (Rong Zhang)
- Sanitise model_number in the ACPI battery driver by dropping
unprintable characters (Kate Hsuan)

Add a binding for the microcontroller (MCU) that fronts the PSE silicon
on a range of managed Realtek-based switches. The host talks only to the
MCU, over I2C/SMBus or UART, using a fixed message-based protocol; the
PSE chips behind it never appear on the bus.
The device is the MCU together with its Realtek firmware: the firmware
and its host protocol are what the binding describes, not the
general-purpose microcontroller they run on. The PSE silicon behind the
MCU (Realtek or Broadcom) is reported by the MCU and detected at runtime,
so it is not described here - hence the 'realtek' vendor prefix.
Two protocol generations exist, both Realtek's, selected by the
compatible: gen1 on older boards (fronting Broadcom PSE silicon) and gen2,
the altered protocol used with Realtek's own PSE silicon. On an I2C
attachment the framing the MCU firmware expects is part of the compatible
as well - '-smbus' or raw '-i2c'; a UART attachment carries no framing
suffix, as the transport is given by the parent serial node.
Each board additionally carries a device-specific compatible that falls
back to one of the protocol compatibles above. Drivers bind on the
protocol compatible; the device-specific string identifies the board and
reserves a place for a future per-board quirk without having to retrofit
device trees already in the field.

KVM arch-neutral and documentation changes for 7.3
- Remove kvm_debugfs_dir if kvm_init() fails after creating KVM's debugfs.
- Document some of the "fun" gotchas with the APIC base when creating IRQCHIPs
on x86.
- Add a per-VM bitmap to track which vCPU IDs have been "claimed" but for
which the vCPU isn't yet online, and use the bitmap to reject duplicate IDs
before calling into arch code. This allows arch code to consume vcpu_id
without having to worry about cross-vCPU clobbering (at least s390 and x86
have had related bugs).
- Zero a vCPU's entry in VMX's Posted Interrupt Descriptor table used for IPI
virtualization when the vCPU is freed to fix a use-after-free where hardware
will write to a freed vCPU's PID.

ASoC: Updates for v7.3
A very busy release, a combination of a lot of new device work and more
people than usual doing various subsystem wide improvements in the code.
The main subsystem level change is the work Morimoto-san has been doing
to get automatic DAI format selection more widely deployed, and even
that is largely changes in the drivers to enable use of the feature
rather than framework work.

Pull crypto library updates from Eric Biggers:
"Add library APIs for most AES encryption modes that are used in the
kernel (ECB, CBC, CBC-CTS, CTR, XCTR, XTS, GCM, CCM).
These AES modes have many in-kernel users that are currently using the
crypto_skcipher or crypto_aead APIs. These existing APIs are difficult
to use and inefficient. Until now, the lack of proper library support
for these has been the main gap in the crypto library.
This set of changes is the next stage of addressing it:
- Implement the new APIs on top of the existing support for
single-block AES in the library.
- Fully document the new APIs.
- Migrate the only user of the old AES-GCM library API to the new,
more flexible API; then remove the old API and its implementation.
- Wire up the new APIs to the traditional crypto API by adding
crypto_skcipher and crypto_aead algorithms.
This makes the new APIs be covered by the traditional crypto API's
self-tests. It also makes them be already used for real on systems
that don't have architecture-optimized code for these modes.
But most importantly, this is a prerequisite for migrating the
architecture-optimized code for these AES modes (i.e.
arch/*/crypto/aes*) into the library, which as usual will eliminate
a lot of redundant "glue" code.
Note that unlike some of the other algorithms that have been migrated
to the library, e.g. SHA-512, for these AES modes there was too much
to get done in one cycle. Nor did it make sense to handle these modes
one at a time, because they tend to be coupled together or depend on
each other, especially in the architecture-optimized AES code.
Thus, most of the benefits (reductions in lines of code, performance
improvements, etc.) will follow in later cycles when
architecture-optimized code is migrated into the library and users of
crypto_skcipher and crypto_aead are updated to use the new APIs.
The design of the new APIs was informed by writing proof-of-concept
patches for many kernel subsystems currently accessing these same
algorithms via crypto_skcipher or crypto_aead (patches 18-33 of
https://lore.kernel.org/r/20260707053503.209874-1-ebiggers@kernel.org/).
While those patches will be resent for real later, the total diffstat
for them was negative 1905 lines. So clearly the new APIs are quite a
bit easier to use and align better with what users actually need.
Besides the new AES encryption APIs, there are also a few changes for
improved AES-CMAC key and context zeroization"

Pull fscrypt updates from Eric Biggers:
"The main change this cycle is a significant simplification that's been
overdue for a while now: standardizing on a single file contents
encryption implementation in ext4 and f2fs, instead of having two.
Specifically, the original filesystem-layer file contents encryption
implementation is removed, and the blk-crypto implementation is now
used unconditionally. blk-crypto delegates either to inline crypto
hardware or to the CPU via blk-crypto-fallback. The latter is
functionally equivalent to the original filesystem-layer code.
The blk-crypto implementation already existed, but previously it was
used only when the filesystem was mounted with "-o inlinecrypt". Now,
"-o inlinecrypt" just selects whether inline crypto hardware is used.
To allow maintaining that user control over hardware use, the
blk-crypto API is extended with a new flag BLK_CRYPTO_CFG_ALLOW_HW.
Overall, this removes quite a bit of redundant code from ext4, f2fs,
and fs/crypto/. It should make things easier for ongoing filesystem
efforts such as iomap support, large folios, and btrfs encryption
(btrfs had already been planning to use blk-crypto exclusively.)
There are two small behavior changes of note:
- Direct I/O now works on encrypted files even without "-o inlinecrypt",
rather than falling back to buffered I/O. This is effectively a
bugfix, though I'll continue to keep an eye out for any user that
may have been depending on the buffered I/O fallback.
- IV_INO_LBLK_32 policies are no longer supported in certain cases
that didn't make sense and have no known uses.
This has been in linux-next since July 22 with no reported issues. All
encryption xfstests pass on ext4 and f2fs. As usual I've also been
using it on a system with an fscrypt-encrypted home directory. Of
course, the blk-crypto code paths also aren't new and were already
being used on many systems via the inlinecrypt mount option.
In addition to the main change described above, there are a few other
cleanups such as using lock guards for mutexes, improving
documentation, and removing a workaround for outdated gcc versions"

"This contains fixes of syzbot reported issue and various fixes in
NILFS2 functionality:
- Reject super-root inode sizes whose computed on-disk footprint
exceeds the filesystem block size (David Lee)
- Replace WARN_ON() in nilfs_cpfile_delete_checkpoints() with
returning -EIO and reporting a filesystem error via nilfs_error()
in the case of corrupted checkpoint count on the storage medium
(Igor Putko)
- Fixed a potential infinite loop in nilfs_clean_segments() reported
by syzbot (Joshua Crofts)
In nilfs_clean_segments(), if err is non-zero, logic logs the error
and sleeps but doesn't abort when it encounters a terminal error
like -EROFS. This causes the thread to loop forever.
Fix this by breaking out of the loop if nilfs_segctor_construct()
returns -EROFS.
- Fix small grammar mistake in the description for nilfs2 recovery
code (Manoj K M)
- Multiple fixes by Ryusuke Konishi:
- fix the list corruption issue recently detected by syzbot, that
can occur when out-of-range values are intentionally passed to
certain GC ioctl parameters
- fix a flaw in the original B-tree implementation related to
truncation and resolves the reported out-of-bounds memory

detected
- fix an issue where a WARN_ON check is triggered by sufile
functions within the log writer after the filesystem degrades
to read-only mode

Tony Nguyen says:
====================
Introduce iXD driver
Larysa Zaremba says:
This patch series adds the iXD driver, which supports the Intel(R)
Control Plane PCI Function on Intel E2100 and later IPUs and FNICs.
It facilitates a centralized control over multiple IDPF PFs/VFs/SFs
exposed by the same card. The reason for the separation is to be able
to offload the control plane to the host different from where the data
plane is running.
This is the first phase in the release of this driver where we implement the
initialization of the core PCI driver. Subsequent phases will implement
advanced features like usage of idpf ethernet aux device, link management,
NVM update via devlink, switchdev port representors, data and exception path,
flow rule programming, etc.
The first phase entails the following aspects:
1. Additional libie functionalities:
Patches 1-5 introduce additional common library API for drivers to
communicate with the control plane through mailbox communication.
A control queue is a hardware interface which is used by the driver
to interact with other subsystems (like firmware). The library APIs
allow the driver to setup and configure the control queues to send and
receive virtchnl messages. The library has an internal bookkeeping
(XN API) mechanism to keep track of the send messages. It supports both
synchronous as well as asynchronous way of handling the messages. The
library also handles the timeout internally for synchronous messages
using events. This reduces the driver's overhead in handling the timeout
error cases.
The current patch series supports only APIs that are needed for device
initialization. These include APIs in the libie_pci module:
* Allocating/freeing the DMA memory and mapping the MMIO regions for
BAR0, read/write APIs for drivers to access the MMIO memory
and libie_cp module:
* Control queue initialization and configuration
* Transport initialization for bookkeeping
* Blocking and asynchronous mailbox transactions
Once the mailbox is initialized, the drivers can send and receive virtchnl
messages to/from the control plane.
The modules above are not supposed to be linked with the main libie library,
but do share the folder with it.
2. idpf:
Patches 6-11 refactor the idpf driver to use the libie APIs for control
queue configuration, virtchnl transaction, device initialization
and reset and adjust related code accordingly.
3. ixd:
Patches 12-15 add the ixd driver and implement multiple pieces of the
initialization flow as follows:
* Add the ability to load
* A reset is issued to ensure a clean device state, followed by
initialization of the mailbox
* Device capabilities:
As part of initialization, the driver has to determine what the device is
capable of (ex. max queues, vports, etc). This information is obtained from
the firmware and stored by the driver.
* Enable initial support for the devlink interface
* '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ixd: add devlink support
ixd: add the core initialization
ixd: add reset checks and initialize the mailbox
ixd: add basic driver framework for Intel(R) Control Plane Function

Pull overlayfs updates from Christian Brauner:
"This lets the merged overlayfs mount itself be idmapped through
mount_setattr(MOUNT_ATTR_IDMAP), in addition to the already supported
idmapped lower and upper layers. The same overlay tree can then be
exposed under a different ownership view.
Overlayfs already normalizes every underlying id through the relevant
layer idmap when ovl_copyattr() copies attributes into the overlay
inode. So the overlay inode's i_uid and i_gid are overlay-final ids.
The overlay mount idmap composes on top of that and is applied at the
overlay-inode boundary only while the underlying layers keep being
accessed with the mounter's credentials through their own (possibly
idmapped) mounts.
So this only changes how the caller sees the overlay inode and never
widens the mounter's access to the layers. The second,
mounter-credential check in ovl_permission() against the real inode
stays on the layer idmap.
Most paths need no change because the VFS applies the mount idmap to
the overlay inode before overlayfs runs or after it returns at the
syscall boundary. Overlayfs only has to change where it bypasses the
generic path.
This also included is a fix for a double end_creating() on the
overlayfs casefold-mismatch path"

Pull misc vfs updates from Christian Brauner:
"Bigger cleanups:
- The lockref dead-count handling is tidied up.
The open-coded check for a count below zero as the dead marker
relies on information the caller should not have.
- make put_mnt_ns() leave mounts connected. Destroying a mount
namespace disconnected its mounts from their mount points. So a
file descriptor still open on the parent of a mount point could be
used to peek under it.
Locked mounts were already kept connected to prevent exactly that.
But a mount is only locked when its tree is copied across a user
namespace boundary. So a mount namespace set up by a privileged
component had no locked mounts and its mounts were disconnected.
Passing UMOUNT_CONNECTED keeps every mount connected and prevents
that bug.
- vfs_prepare_mode() passes S_IFDIR for directories. I meant to fix
that ago but didn't get to it. So now someone finally did it.
This kills the exception where the mode could be 0 when a directory
was created whereas every other creation operation passed it
explicitly already.
- move long delayed work for ufs, jffs2, hfsplus, hfs and affs from
the per-cpu system_long_wq to the new unbound system_dfl_long_wq.
None of that work relies on per-cpu state and the work item is
enqueued with queue_delayed_work() whose timer is global anyway. So
it may as well benefit from scheduler task placement.
Smaller fixes and cleanups:
- unlock_buffer() and journal_end_buffer_io_sync() use
clear_and_wake_up_bit()
- the pipe page pools are unified into a single per-pipe pool and the
extra wake_up(rd_wait) is limited to EPOLLET consumers
- eventpoll now computes its timer slack lazily in ep_poll()
- shrink_dcache_for_umount() keeps making progress on busy roots
- excess xarray nodes are freed in clear_inode()
- romfs detects hard link cycles

shrink
