git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core
Pull driver core updates from Danilo Krummrich:
"container_of:
- Apply typeof_member(), remove the local __mptr variable to
eliminate variable shadowing warnings on nested container_of()
calls, and remove unnecessary parentheses
core:
- Add driver name to probe debug print for initcall_debug
- Avoid repeatedly printing the same 'Fixed dependency cycle' log
- Unwind device_add() on attribute creation failure in
attribute_container_add_class_device()
- Remove statistics group if encryption group creation fails in
transport_add_class_device()
debugfs:
- Fix lockdown check for mmap_prepare()
- Warn if file creation failed due to uninitialized debugfs
device property:
- Implement fw_devlink support for software nodes by adding
software_node_add_links(), which creates fwnode links from
DEV_PROP_REF properties to enable automatic probe ordering. Add
kunit-managed fwnode helpers and test coverage
- Fix infinite loop in fwnode_for_each_child_node() when the
secondary fwnode has more than one child. Add test cases
- Fix out-of-bounds access in software_node_get_reference_args() when
called with index -1 (UINT_MAX)
- Refactor to use RAII approach with __free()
- Add Bartosz Golaszewski as software node reviewer
firmware loader:
- Fix race where a sysfs fallback request can complete before being
queued as pending, leading to a use-after-free on the next fallback
request
- Reject 0-size built-in firmware and fail the build on empty
firmware files in CONFIG_EXTRA_FIRMWARE
kobject:
- Provide __KOBJ_ATTR() and __KOBJ_ATTR_RO/WO() initialization macros
and allow the constification of kobject attributes, enabling them
to reside in read-only memory
platform:
- Provide platform_device_set_of_node(), platform_device_set_fwnode(),
and platform_device_set_of_node_from_dev() helpers that encapsulate
firmware node reference counting for dynamically allocated platform
devices
Convert all in-tree users that manually assigned dev.of_node or
dev.fwnode, fixing a pre-existing refcount bug in powermac. Switch
to counting references of all firmware node types, not only OF
nodes
- Unify the release path for dynamically allocated platform devices
by removing platform_device_release_full(). Amend the fwnode setter
API contract to warn if a primary software node is overwritten. Add
KUnit tests for correct software node removal on device
unregistration
Rust:
- Auxiliary:
- Add registration_data_with() closure-based API for invariant
ForLt types
- Debugfs:
- Migrate BinaryWriter and BinaryReaderMut trait requirements
from kernel::transmute traits to zerocopy traits
- Device:
- Add BoundInternal device context and InternalBoundContext trait
for bus abstractions that need internal access to a bound
device.
- Make the lifetime on Core and CoreInternal invariant to prevent
coercion to shorter lifetimes
- Devres:
- Fix race between concurrent revokers where the losing revoker
could return before the winning revoker finished dropping the
inner data, causing use-after-free.
- Ensure revocation is complete before the device finishes
unbinding by making the synchronization bidirectional.
- Add DevresLt<F: ForLt>, a wrapper around Devres that shortens
'static back to the caller's borrow scope. Implement ForLt and
CovariantForLt for Bar, IoMem, and ExclusiveIoMem
- Driver:
- Switch from index-based to pointer-based device ID info lookup,
storing static references in driver_data. Centralize device ID
handling in device_id.rs, removing the open-coded ACPI/OF
matching logic and duplicate ID table from driver.rs
- I/O:
- Make I/O regions typed (with a dynamically-sized Region type
for the existing untyped case), create view types representing
subregions of a mapped I/O region, and add io_project!() for
safely creating subviews.
- Split Io into a base trait (IoBase) and an extension trait (Io)
with a blanket implementation, preventing implementers from
overriding provided methods that unsafe code relies on.
- Add a SysMem backend for shared system memory with volatile
access, and make Coherent implement Io via an I/O view type.
Add IoSysMap as sum type of Mmio and SysMem. Add copying
methods (memcpy_{from,to}io()) and read_val()/write_val() for
typed access.
- Replace dma_read!()/dma_write!() with io_read!()/io_write!()
for primitives and copying methods for aggregates; drop the old
macros. Convert nova-core to use I/O projection.
- Fix internal shortcut rule dispatch in the register!() macro,
remove unused rule arguments, and use path fragments for alias
destinations
- IRQ:
- Make irq::Registration compatible with lifetime-bound drivers
by removing the 'static bound on Handler/ThreadedHandler and
replacing Devres<RegistrationInner> with direct
request_irq()/free_irq() calls. Handlers can now directly own
lifetime-bound device resources
- PCI:
- Convert IrqVectorRegistration to a lifetime-annotated owning
type, giving drivers explicit control over the allocation
lifetime. IrqVector embeds a resolved IrqRequest, making the
conversion infallible. Remove the redundant
request_irq()/request_threaded_irq() wrappers from pci::Device.
- Add pci_irq_type() C helper and expose it via irq_type() on
IrqVectorRegistration and IrqVector, returning PCI_IRQ_MSIX,
PCI_IRQ_MSI, or PCI_IRQ_INTX.
- Mark pci::Device refcount methods inline
- Serdev:
- Add Rust abstractions for the serial device bus, including
serdev::Driver trait, serdev::Device wrapping struct
serdev_device, and serdev::Adapter implementing
RegistrationOps. Includes a sample driver. Markus Probst takes
over as serdev maintainer for both C and Rust code
- Misc:
- Split ForLt into a base trait (providing the Of<'a> GAT) and an
unsafe CovariantForLt subtrait guaranteeing covariance,
enabling invariant types (e.g. those containing Mutex<&'bound T>)
to participate in the ForLt abstraction.
- Fix Coherent read past EOF returning -ERANGE instead of zero.
- Fix firmware example UB by avoiding null-pointer ARef
misc:
- Avoid iattr allocation in kernfs listxattr by using
kernfs_iattrs_noalloc().
- Unregister SoC bus on early device registration failure.
- Remove unused DMA_FENCE_TRACE Kconfig symbol.
- Fix /sys/module path in comment.
- Refactor ISA bus init to remove nested blocks.
- Remove redundant nodemask clears in numa_init().
- Add kernel-doc for fwnode_operations and sys_soc.h, mark
internal property data as private for kernel-doc, and add
property.h/fwnode.h to driver-api infrastructure docs.
- Add MAINTAINERS entry for sys_soc.h"

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.

pmem_submit_bio() passes the parent bio to nvdimm_flush() for
REQ_FUA. For virtio-pmem this makes async_pmem_flush() allocate
and submit a child PREFLUSH bio chained to the parent.
That child allocation is in the block submit path. Making it
blocking with GFP_NOIO can consume the same global bio mempool that
submit_bio() uses, while making it GFP_ATOMIC can fail under
pressure. A forced failure of the child allocation produced:
virtio_pmem: forcing child bio allocation failure for test
Buffer I/O error on dev pmem0, logical block 0, lost sync page write
EXT4-fs (pmem0): I/O error while writing superblock
EXT4-fs (pmem0): mount failed
Avoid the child bio without turning REQ_FUA into a synchronous
submit-path wait. Let provider flush callbacks return
NVDIMM_FLUSH_ASYNC after taking ownership of parent bio completion.
pmem_submit_bio() returns in that case, and virtio-pmem queues an
ordered WQ_MEM_RECLAIM work item that runs the existing host flush
path and completes the parent bio.
This keeps the asynchronous completion model of the child-bio path
while removing the child bio allocation from the submit path.

The generic virtio bus .shutdown handler, virtio_dev_shutdown(), breaks
and resets a device once it has established that the driver has no
.shutdown of its own. A driver that does implement .shutdown, to quiesce
its own activity first, still needs the same break and reset afterwards
and would otherwise have to open code it.
Factor the break + synchronize_cbs + reset sequence out of
virtio_dev_shutdown() into an exported virtio_device_shutdown() helper so
such drivers can reuse it instead of duplicating the core logic.
No functional change.

- 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

Pull ARM SoC platform updates from Arnd Bergmann:
"The 32-bit Arm platforms are a bit more interesting this time: I
refreshed an earlier series to mark code as deprecated that does have
the tendency of getting in the way of cleanups and new features but
has close to zero users. Among these are:
- 22 of the remaining 28 legacy board files that predate the current
devicetree based descriptions, using old chips from Intel and
Marvell. The remaining six board files are for TI OMAP1 and Samsung
s3c64xx chips and all still have known users.
- support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
machines based on these. These all use devicetree but the CPU
support causes disproportional work. Most of them are just
reference boards, the notable exceptions being the Nokia N800/N810
tablet and the Buglabs BUG platform.
- be8, be32, oabi and iwmmxt userspace binaries, which were mostly
associated with the platforms now scheduled for removal and are
increasingly problematic to support with modern toolchains.
Nothing is actually removed at this point, to ensure that any
remaining users continue to have the 7.3-LTS for a while longer.
Patches for removal are currently being tested.
Other updates include a continued work to convert GPIO number based

Pull SoC driver updates from Arnd Bergmann:
"The SoC driver changes once more consist of many small fixes and
cleanups, that are to a large part the result of automated testing.
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

Pull timer and timekeeping core updates from Thomas Gleixner:
- Fix a subtly inconsistency in the timekeeping code, which fails to
account for the monotonicity adjustment in ntp_error.
For small changes of the clocksource multiplicator (+/-1) which are
typically used by the NTP PLL this is hard to observe. But for larger
adjustments, e.g. caused by a direct frequency setting through
adjtimex() the one-time uncompensated offset is significant.
Cure this by adjusting ntp_error with the resulting offset so that
the discrepancy is smoothed away over time
- Make tick length calculations correct in NTP.
The timekeeping core takes the quantisation of the clocksource into
account when calculating the tick length to compensate for the
deviation of the nominal NTP_INTERVAL_LENGTH.
While timekeeping gets this right, NTP is not aware of that, which
means it operates on the nominal value and not on the actual value
which is determined by the clock source frequency. The rounding of a
coarse clocksource like the ACPI PM timer results in a +127 PPM
deviation.
Cure this by exposing the deviation to the NTP code so that it can
operate on the same data as the timekeeping core. This is purely
kernel internal. User space still sees the nominal tick lenght via
adjtimex().
- The accuracy of the NTP adjustments is fairly approximate as the code
assumes that the invocations are precisely in NTP interval frequency
ticks and the final adjustment can over and under-run.
Cure this by adjusting ntp_error by the intended skew on each tick to
achieve the desired rate.
- Handle the two competing skews of time offset and time adjustment
correctly by calculating the conflict portion between the skews and
adjusting both accordingly.
- A set of updates and improvements for the selftests

Pull treewide timer related cleanups from Thomas Gleixner:
- Remove the leftover CLOCK_TICK_RATE which has been scheduled for
removal more than a decade ago along with some now empty asm/timex.h
files.
- Consolidate delay timer calibration
The construct of having a define in a header requires that
architectures provided asm/timex.h for no reason. Also the function
name for reading the delay timer is confusing at best.
Use a config switch to enable that functionality and rename the
function to delay_read_timer() to make the purpose clear.
This removes some more now empty asm/timex.h files as well.

Pull SMP core updates from Thomas Gleixner:
- Reduce the preemption disabled sections in smp_call_function*().
The various smp call functions keep preemption disabled accross the
full operation which includes the wait for completion. Especially the
latter can take some time when one of the target CPUs is not
immediately responding to the IPI, which can result in large latency
spikes.
To improve this provide a per task CPU mask to track the CPUs to wait
for. That makes the information required for the wait task local and
therefore allows to reenable preemption before the wait.
While this comes with moderate extra memory cost this reduces SMP
function call induced latency measured in a fleet for high priority
tasks from ~17ms to ~1.5ms (~90%).

memory barriers with smp_store_release()/acquire()

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.

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

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

KVM x86 misc changes for 7.3
- Fix VPID virtualization bugs where KVM would fail to flush hardware TLBs.
- Harden the SNP and TDX "populate" ioctls against bad input, and to prepare
for supporting in-place private<=>shared conversion.
- Fix a variety of #DB priority bugs.
- Fix a class of races related to enabling Hyper-V emulation on a vCPU after
the vCPU is visible to the rest of KVM.
- Use static calls for nested virtualization ops.
- Move more KVM-internal code out of x86's kvm_host.h.
- Enumerate support for a variety of Zhaoxin instructions that don't require
explicit virtualization.
- Fix missing EFER validation bugs, including in the KVM_SET_SREGS* path.
- Harden kvm_vcpu_map() against double-mapping and thus leaking references.

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.

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"

Pull HFS updates from Viacheslav Dubeyko:
"This contains several fixes in HFS/HFS+ of syzbot reported issues and
HFS/HFS+ fixes of xfstests failures.
- b-tree bitmap corruption check (Aditya Prakash Srivastava)
During b-tree open (hfs_btree_open()), the code verifies that the
allocation map bit for the tree header (node 0) is set. If not, it
indicates a corrupted map record/bitmap and mounts the volume as
read-only (SB_RDONLY) to prevent further damage.
- Validate catalog CNIDs before instantiating inodes (David
Maximiliano Hermitte)
The hfs_cat_find_brec() first resolves a catalog thread record by
CNID and then looks up the corresponding catalog record by
parent/name. On a corrupted filesystem image, the second lookup may
find a record whose CNID does not match the CNID that was
requested. Finally, corrupted catalog records are rejected.
- Validate B-tree record offset table (Jiaming Zhang)
A crafted HFS+ image can contain a corrupted B-tree node. The node
descriptor may contain a record count that does not fit in the
node, and record offsets may be unordered, unaligned, outside the
node, or point into the offset table itself. Validate num_recs
against the node size before walking the record offset table.
Reject record ranges that are unordered, unaligned, outside the
node, or overlapping the offset table. Reject invalid record
indexes before reading their offset entries, and avoid decrementing
an already-zero leaf_count.
- Refactoring of hfsplus_delete_cat() logic (Kyle Zeng).
The hfsplus_delete_cat() is called with str == NULL when the last
open reference to an unlinked HFS+ hardlink backing inode is
closed. In that case, the function finds the catalog thread by CNID
and rebuilds the catalog key from thread.nodeName. A corrupted
image can therefore provide an oversized thread name length and
make hfs_bnode_read() write past the catalog search-key allocation.
Read the CNID record through hfsplus_brec_read_cat(), which bounds
the record read to sizeof(hfsplus_cat_entry) and verifies that a
thread record's size exactly matches nodeName.length.
- Cleanup in KUnit test (Mohammad Shahid)
The kfree() safely handles NULL pointers, so the explicit NULL
check in free_mock_str_env() before calling kfree() is unnecessary.
The rest contain fixes of generic/564 xfstests' test-case failure
for the case of HFS+ file system, syzbot reported issue in
hfs_mdb_commit() and hfs_mdb_close() methods of HFS file system,
and reworking the MDB locking scheme in HFS file system"

====================
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
idpf: print a debug message and bail in case of non-event ctlq message
idpf: make mbx_task queueing and cancelling more consistent
idpf: refactor idpf to use libie control queues
idpf: refactor idpf to use libie_pci APIs
idpf: remove unused code for getting RSS info from device
idpf: remove 'vport_params_reqd' field
libie: add bookkeeping support for control queue messages
libie: add control queue support
libeth: allow to create fill queues without NAPI
libie: add PCI device initialization helpers to libie
virtchnl: move virtchnl and virtchnl2 headers to 'include/linux/net/intel'

Pull vfs writeback updates from Christian Brauner:
"This makes sync_inode_metadata() and writeback_single_inode() persist
not only the inode but all metadata associated with it.
A new .sync_inode_metadata superblock operation is called from
__writeback_single_inode(). Alongside it a new I_METADATA_WRITEBACK
state flag is added.
Filesystems no longer need their own mmb_fsync() implementations and
can just use simple_fsync(). All metadata is now written for IS_SYNC
and IS_DIRSYNC inodes. Races where several fsyncs raced and mmb_sync()
could return before all buffers were really persisted are fixed since
I_SYNC now serializes properly.
The I_METADATA_WRITEBACK scheme also fixes the case where a
WB_SYNC_NONE writeback landing between write(2) and fsync(2) left
fsync(2) failing to persist the inode. That problem is not specific to
filesystems using the generic metadata bh tracking, and the ones that
do not are left alone.
ext2, udf, bfs, minix, fat and ext4 in nojournal mode have their data
integrity writeout fixed and are converted. affs drops metadata bh
tracking and mmb_fsync() is removed.
A few other fixes came out of this:
- a UAF in mark_buffer_write_io_error()
- missed inode writeback when racing with __writeback_single_inode()
- ext4 allocating the mapping_metadata_bhs struct on demand
- three fat fixes: a lost inode update in do_msdos_rename() with
DIRSYNC, inode buffer write errors not propagating out of
fat_sync_inode_metadata() and directory entries not being
persisted on fsync(2) of the root directory"
