Pull VFIO updates from Alex Williamson:
- Add nv_falcon vfio selftest driver.
The Falcon is a general-purpose microcontroller embedded within
NVIDIA GPUs, presenting a relatively simple DMA programming
interface.
This adds another selftest target for vfio-pci with real DMA
transfers (Rubin Du, Alex Williamson)
- Add allocation assertion helpers to vfio selftests and use them to
avoid variable length arrays and the compiler errors they generate
(Alex Mastro)
- Fix use-after-free hazard where an init path error in MSI support
leaves a stray pointer that can later be reused or double-freed
(Xiang Mei)
- Fix previous refactor of PCI BAR mappings to honor non_mappable_bars
flag, which otherwise generates a warning when trying to pci_iomap()
a 256TiB BAR on ISM devices on s390 (Farhan Ali)
- Add igb vfio selftest driver.
Like nv_falcon, this provides another target for DMA testing with
vfio selftests, but importantly this driver supports both physical
82576 NICs and the emulation model in QEMU.
This therefore enables a vfio selftest vector with no physical
hardware requirements (Josh Hilke, Alex Williamson)
- Mark selftest fixture objects __maybe_unused to accommodate builds
with clang -Wunused-but-set-global (David Matlack)
- Add error recovery for vfio-pci devices on s390x.
This expands devices which expose the existing error eventfd and
introduces a device feature for reporting firmware defined error
state information to the user, allowing recovery through hypervisor
channels (Farhan Ali)

encode_layoutstats_maxsz budgets XDR_QUADLEN(PNFS_LAYOUTSTATS_MAXSIZE),
i.e. 256 bytes, for the layoutupdate4 body written by the layout driver.
The flexfiles record can exceed that.
ff_layout_encode_ff_layoutupdate() emits, per data server, a netaddr4,
an nfs_fh4, two ff_io_latency4, an nfstime4 and a bool. A data server
whose filehandle is NFS_MAXFHSIZE bytes long already accounts for 132 of
those bytes, and the two ff_io_latency4 at 64 bytes each, the nfstime4
and the bool add a further 144, so the body passes 256 bytes before the
netaddr4 is encoded at all. encode_layoutstats() additionally writes
the deviceid4 and the layoutupdate4 lou_type word, neither of which the
macro accounts for.
The filehandle and the address are both chosen by the server, through
LAYOUTGET and GETDEVICEINFO, so it can drive the encoder past the
end of the send buffer. xdr_reserve_space() returns NULL once that
happens, and the two ff_layout_encode_io_latency() calls run with
dss_info->mirror->lock held, so a NULL return there leaves the lock
permanently held.
Raise PNFS_LAYOUTSTATS_MAXSIZE to 384 so that the record fits inside the
reservation.

The network and transport header fields in struct sk_buff are 16-bit
offsets from skb->head, and U16_MAX is reserved as the unset transport
header value. batadv_tvlv_call_handler() sets both fields from a received
multicast TVLV without checking whether the TVLV end is representable.
If the end offset exceeds the field's range, skb_set_transport_header()
truncates it so that the transport header precedes the network header.
The negative difference is then returned by skb_network_header_len() as
a large u32. batadv_mcast_forw_packet() consequently accepts an oversized
multicast tracker and accesses memory beyond the skb data.
Add skb_set_transport_header_careful(), an offset-aware counterpart to
skb_reset_transport_header_careful(), which validates the final
head-relative offset before assigning it. Use the new helper in
batadv_tvlv_call_handler() and reject unrepresentable TVLVs before
setting the network header.

Pull nfsd updates from Chuck Lever:
- CB_NOTIFY support for NFSD's NFSv4.1 directory delegations
The server used to recall a delegation as soon as the directory
changed. NFSD now watches delegated directories through fsnotify and
reports adds, removes, renames, and directory attribute changes,
carrying the filehandle and attributes of the affected entry, so
clients can keep their caches. Some of the NOTIFY4 flags come from
RFC 8881bis (Jeff Layton)
- Continued netlink work
A new server-stats-get operation reports what /proc/net/rpc/nfsd
publishes, plus NFSv4 callback counts, and SUNRPC now keeps its
per-procedure call counts per network namespace, so a container sees
its own numbers. nfsstat reads all of this over netlink, with a
procfs fallback for older kernels (Jeff Layton)
- Remove SUNRPC service thread pool mode selection
Per node is the right choice on any host we run today, so the auto,
global, and percpu modes have been removed. A single-node host still
gets one pool. A multi-NUMA host now gets a pool per node.
sunrpc.pool_mode accepts the old names but no longer selects
anything.
- Bug fixes, clean-ups, and small optimizations:
- async COPY offload rework (Jeff Layton)
- more use-after-free fixes in the NFSv4 state revocation paths
- percpu counter contention removed from the reply cache and IO
accounting
- a long list of hardening fixes (Chris Mason)

mlx5_query_vport_max_tx_speed() was introduced to serve the
query_port_speed path, which uses max_tx_speed == 0 when port is down.
This is incorrect for callers that need the actual configured speed
regardless of vport state, such as modify-vport-state helpers
that must preserve the speed across state transitions.
Move this logic to the caller function in the verb flow and let
mlx5_query_vport_max_tx_speed() return the raw firmware value
unconditionally.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext updates from Tejun Heo:
"Most of this cycle completes the enqueue-path support for hierarchical
sub-scheduling, which makes sub-scheduler support feature complete: a
root BPF scheduler can now hand a cgroup subtree over to a nested
sub-scheduler together with revocable CPU grants, and the
sub-scheduler owns all scheduling decisions for its tasks on those
CPUs.
Development volume was high and a number of changes plugging holes in
the new support landed late in the cycle. Also included are core
scheduling fixes that were completed too late for the v7.2 release and
are routed through this pull request.
Sub-scheduler CPU delegation:
- Parent schedulers now grant and revoke per-CPU capabilities
(enqueueing, preemption, CPU frequency control) on their children,
enforced on every path a scheduler can reach a CPU through.
Previously only dispatching could be delegated; this lets
sub-schedulers fully schedule their CPUs.
- Rescue execution: a task whose scheduler doesn't have access to the
CPUs the task needs to run on starved until the watchdog ejected
the whole scheduler. The kernel now runs such tasks directly on a
small bandwidth budget, turning a scheduler-killing failure into
bounded degradation.
- Cgroup integration: tasks migrating across a sub-scheduler boundary
weren't re-homed to the new owner, causing wrong-scheduler
scheduling and a use-after-free. Sub-schedulers now take over their
cgroup subtree and receive its cgroup callbacks.
- Arena objects now cross the kernel/BPF boundary as typed pointer
arguments, translated transparently by the BPF tree's new arena
argument support, replacing untyped arguments with manual
translation.
- scx_qmap now demonstrates full hierarchical sub-scheduling.
Other fixes and updates:
- Robustness improvements: the abort path is now NMI-safe, fixing
deadlocks when errors are raised from NMI context and making
hardlockup recovery direct. Reenqueue loops that could monopolize a
CPU ahead of the watchdog now eject the offending scheduler, and
stalls are blamed on the scheduler actually responsible.
- Hardening: BPF-writable arena memory is validated before kernel
use, and task slice and vtime writes got explicit synchronization
rules, closing corruption vectors open to buggy or malicious
schedulers.
- Core scheduling: sched_ext dispatching can drop the rq lock inside
the core-wide pick, which let interleaving selections corrupt each
other's state and hard-hang the machine. The selection now restarts
when the lock was released. The task ordering callback was also
invoked with its arguments swapped, and the default ordering is
updated to work across sub-scheduler boundaries. The fixes are
marked for stable.
- Other fixes headed for stable: a task init leak on fork failure
during enable, tooling compat macros that silently failed to detect
newer kernels, and a crash on reenqueueing against a destroyed
dispatch queue.
- Tooling: scx_pair moves off deprecated callbacks, and the
deprecated scx_bpf_cpu_rq() kfunc is removed"

Pull cgroup updates from Tejun Heo:
- Attach path bug fixes: migrations spanning multiple source or
destination cpusets were mishandled, most visibly leaving thread
affinities stale when the controller is disabled in a threaded
subtree. Configuration writes could also race an in-flight attach and
apply stale state, and the deadline task count could get corrupted by
concurrent updates, skewing SCHED_DEADLINE admission decisions.
- Memory binding bug fixes: which node masks get applied differed
between the binding update paths, and tasks cloned with
CLONE_INTO_CGROUP skipped rebinding entirely. Rebinding also now runs
once per process instead of repeating for every thread sharing the
mm.
- Overhead removals with no behavior change: CPU hotplug iterated tasks
of cpusets that just inherit the parent's effective masks, and the
slab-spreading task flag was still being maintained although the SLAB
allocator that consumed it is long gone.
- Data-race annotations for benign races so that KCSAN reports stay
meaningful, selftest coverage for the fixes above along with
flakiness and portability fixes, and documentation corrections.

A younger me put a WARN in might_sleep() to warn about nested sleep loops. This
younger me also build a wait-loop variant that can deal with it. This wait-loop
variant doesn't have all the fancy wrappers, since it isn't used much. It also
lacks wait-bit support.
Add the wait-bit support and use it to fix the nested wait issue.

Jiri Olsa reports slowdown of tracing_multi benchmark that allocates huge
number of trampolines [1].
The slowdown caused by extra protection changes in execmem_alloc_rw() and
execmem_free().
With ROX caches enabled, all execmem allocations except EXECMEM_MODULE_DATA
are ROX after the allocation. execmem_alloc_rw() temporarily sets them to
W+NX and execmem_free() resets them back to ROX.
The only user of bpf_jit_alloc_exec_rw() is x86::arch_bpf_trampoline_size()
that only needs a temporary writable buffer in the modules address space.
On x86 executable memory and module data are constrained to the same
address range, so x86::arch_bpf_trampoline_size() can directly use
execmem_alloc(EXECMEM_MODULE_DATA)
Replace the call to bpf_jit_alloc_exec_rw() with a call to
execmem_alloc(EXECMEM_MODULE_DATA) in x86::arch_bpf_trampoline_size() and
drop bpf_jit_alloc_exec_rw() helper.

Pull networking updates from Jakub Kicinski:
"One of the 'small improvements all over the place' releases for us.
It's hard to draw any direct comparisons because summer vacations
disrupted our patch processing (and presumably - generation) quite a
bit.
Quick and dirty count suggests we (Paolo and I) merged a very similar
number of net (632) and net-next (648) patches. This is not telling
the full story either because 1/3 to 1/2 of the net-next patches also
*seem* like AI-driven low priority fixes, cleanups and clarifications.
We are completely overwhelmed, of course. The glimmer of hope is that
we secured sufficient LLM budget and access (thank you Meta!) to run
reviews with multiple frontier models on each patch. This eliminates
some hallucinations. That said, in terms of review, the LLMs can only
do so much.
The sad truth is that our APIs (especially for rare events like PCIe
errors, timeouts etc) have always been racy, and now LLMs don't let us
ignore that. I expect our direction for the next release will be to
tweak the reviews a little bit more, but start shifting focus to
letting the LLMs take care of the busy work - managing patchwork,
automating common process complaints, editing commit messages, and
maybe applying patches which already got "reviewed-by" tags from
people we trust...

"Major changes:
- Redesign the verifier error reporting: failures now carry source
and instruction annotations along with the causal event history
that led to them, making program rejections far easier to debug and
repair (Kumar Kartikeya Dwivedi)
- Add arena argument support to kfuncs and struct_ops through the new
__arena and __arena__nullable suffixes (Tejun Heo, Puranjay Mohan,
Kumar Kartikeya Dwivedi, Ihor Solodrai)
- Signed BPF program loader rework to accommodate both BPF and
security community needs where the kernel runs the signature
verification at BPF_PROG_LOAD time before the LSM admission hook
(Daniel Borkmann)
- Add a set of ksock kfuncs which let BPF LSM and syscall programs
create, connect and send on UDP sockets in order to emit telemetry
data (Mahe Tardy)

loops no longer pay a kfunc call on every iteration (Puranjay
Mohan)
- Add an arena-based bitmap data structure to libarena along with
serial and parallel selftests (Emil Tsalapatis)
- Teach resolve_btfids to discover kfuncs from the kernel's BTF ID
sets and to emit kfunc BTF decl tags, reducing the kernel build's

- Add BPF_F_ADJ_ROOM_DECAP_* flags to bpf_skb_adjust_room() so that
tunnel decapsulation can update the GSO and encapsulation state of
the skb (Nick Hudson)
- Fix the ring buffer pending_pos walk and the available-data

instead of relying on the verifier's hard-coded allowlist (Kaitao
Cheng)
- Introduce global percpu data for BPF programs with libbpf probing

account for preempt and IRQ disabled regions as overlapping RCU
protection (Ning Ding)
- Support mixing bpf2bpf calls and tail calls on RV64, add signed
operations and 32-bit atomics to the RV32 JIT, and add timed
may_goto support (Pu Lehui, Kuan-Wei Chiu, Feng Jiang)
- Fix a use-after-free on mm_struct in bpf_find_vma() for foreign
tasks and an mmap_lock leak in the irq_work path (Sanghyun Park)
- Populate mmap-able BPF array map memory lazily which makes mmap()

efi_guid_to_str() only formats the GUID through the byte array passed to
the UUID printf formatter. It does not modify the GUID contents.
Make the input pointer const so callers can stringify GUIDs from const

x86's efi_crash_gracefully_on_page_fault() ends in an infinite
schedule() loop so the kworker that faulted in firmware never runs
efi_rts_wq again. A later change needs the same "park this worker
forever" primitive on the runtime service timeout path, so factor the
loop into a shared efi_rts_park_worker() and call it from the x86
page-fault handler.
No functional change.

A read from /proc/sys/kernel/sched_rt_runtime_us leads to backtrace due
to missing cpu_hotplug_lock with CONFIG_CPUSETS=n. The callchain is
sched_rt_handler() -> partition_sched_domains() -> sched_cache_set() ->
static_key_enable_cpuslocked(&sched_cache_present).
sched_cache_set() itself is also invoked from sched_init_domains() which
is early during the boot, holding just the sched_domains_mutex_lock().
Here is no warning because it happens before user space is running (and
hotplug operations are not possible).
There is also sched_cache_active_set() which acquires the hotplug lock
before invoking any of the _cpuslocked() functions.
This is only a problem with CONFIG_CPUSETS=n because in the =y case the
other implementation of rebuild_sched_domains acquires the CPU-hotplug
lock.
Acquire CPU hotplug lock before in rebuild_sched_domains(), before
partition_sched_domains() is invoked for the CONFIG_CPUSETS=n case.

In gicv5_irs_of_init(), an IRS is set-up using of_io_request_and_map() to
request its memory region (corresponding to the configuration frame) and
map the IRS configuration frame.
On gicv5_irs_of_init() failure, the driver unmaps the IRS iomem region but
does not release the requested memory region leaving it allocated in the
iomem resource tree.
Fix it by releasing the iomem region on gicv5_irs_of_init() probe failure.
Likewise, on both OF and ACPI driver init failure, IRS iomem regions are
requested but never released in gicv5_irs_remove().
Stash a copy of the IRS iomem region in a struct resource in
struct gicv5_irs_chip_data and use it to release the requested region in
gicv5_irs_remove() if the driver probe fails.

git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull integrity updates from Mimi Zohar:
- TPM initialization is sometimes delayed until deferred_probe_initcall
Since ordering is not guaranteed within the same initcall level, IMA
may initialize before the TPM and fall back to TPM-bypass mode. A new
config option, CONFIG_IMA_INIT_LATE_SYNC, allows those building the
kernel to defer IMA initialization to late_initcall_sync, accepting
the integrity risk of missing early measurements in exchange for
avoiding TPM-bypass mode.
- The raw policy rules are now measured, as well as the complete
policy, closing a gap in integrity measurement coverage

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Expose btf_ids to trace events
In order to allow BPF programs to attach to system call trace events
(which are actually pseudo trace events built on top of raw_syscall
events), expose the BTF ID of the events. This will allow BPF
programs better precision in attaching to events.
- Use "u64" to assign to hist_field->type
Instead of using kstrdup("u64", GFP_KERNEL) to assign the
hist_field->type, just point it to "u64" instead. The
hist_field->type is freed via kfree_const().
- Replace kmalloc()/strcpy() with kstrdup() for trace_printk
Instead of having two calls to copy the module format string, just
use kstrdup().
- Use __free() in trace event histograms and triggres where possible
- Use seq_buf in trace event code instead of strcat()
Instead of calculating the size of the buffer to use and filling it
with strcat(), use the seq_buf infrastructure that takes care of
making sure not to overflow the string size.
- Reject invalid preemptirq_delay_test CPU affinity
The preempt_delay_test module can take an invalid CPU affinity mask
and create confusing output. Simply have the module reject invalid
affinity masks.
- Prevent division by zero in ftrace_ops sample module code
If the ftrace_ops sample module code receives the module parameter
nr_function_calls set to zero, it can cause a division by zero error.
- Warn when an event dereferences a parameter in TP_printk()
On boot up and module load, the trace event TP_printk() is scanned
for possible bugs. As the TP_printk() code is executed when the user
reads the "trace" file and processes the data written when the
trace_event executed, the data it reads can be literally days old.
The scan currently checks for dereferencing printk formats like
"%pI6". But it does not check if the parameters themselves have a
dereference like:
TP_printk("offset %08x: value %08x",
(u32)(__entry->addr - __entry->edma->membase), __entry->value)
__entry represents the pointer to the event on the ring buffer. The
__entry->edma->membase is dereferencing a pointer on the ring buffer
to find membase, but the __entry->edma may no longer be a valid
pointer.
Warn on this case too.
- Replace some strcpy() with strscpy()
- Clean up mmiotrace events to use assign_type() macro
The assign_type() macro makes sure the event type is indeed the type
that is being parsed. The mmiotrace trace was written before that
macro was created so it just simply typecasted the pointer.
Replace the typecasting with the macro.
- Have the ENUM processing to numbers only process what is added
The code that converts ENUMs to their numbers in the trace events
scanned all events to do the processing. This was true when a module
was loaded too. That is, instead of processing just the events for
the module, it processed *all* events. Even the builtin ones that
were processed at boot up.
Add a check for the event->module matching mod if it is a module
before processing it.

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 gpio updates from Bartosz Golaszewski:
"GPIO core:
- extend the gpio-regmap abstraction layer with more features
allowing users to override configuration setting, translate
register values and masks and enable/disable interrupts
- extend GPIO kunit tests with suites verifying probe ordering by
software node devlink support and software node hogs
- shrink GPIO kunit initialization code
- coding style updates (remove commas from sentinels where
applicable)
- with all users now converted treewide to using real firmware node
links for software node GPIO lookup: remove the deprecated
label-matching mechanism from from GPIO core
- drop redundant return value check of nonseekable_open() in
gpiolib-cdev
- use IRQ trigger helpers where applicable
Driver updates:
- refactor error paths and logging in gpio-nomadik
- use more modern interfaces for getting resources in gpio-rockchip,
gpio-bt8xx and gpio-pca9570
- add missing MODULE_DEVICE_TABLE() to gpio-sifive and gpio-vf610
- drop unused FILONOFF macro from gpio-rcar
- extend build coverage of ioport GPIO drivers with COMPILE_TEST=y
- only enable the gpio-rtd driver by default with ARCH_REALTEK=y to
avoid bloating the build
- refactor coding style in several drivers
- use correct endianess translation in gpio-pcf85x
- add wake-up interrupt support to gpio-mvebu
- apply initial value in direction output setter in gpio-by-pinctrl
Misc:
- replace linux/gpio.h inclusions treewide with linux/gpio/legacy.h
which now exports all the deprecated APIs
- select GPIOLIB_LEGACY in Kconfig where required treewide
- use software nodes for gpio-keys in MFD drivers
Devicetree bindings:
- describe the realtek rtd1625 GPIO controller
- document new models for gpio-pca95xx and gpio-cadence
- document new property in gpio-rockchip"

Pull input updates from Dmitry Torokhov:
- A new driver and device tree binding for Imagis ISA1200 haptic motor
controller
- Improvements to input core opening, closing and inhibiting devices,
ensuring devices are fully ready before delivering events, deferring
handler start() until the device is opened, resyncing state on
uninhibit, and rejecting inhibit requests during unregistration
- Updates to cap11xx capacitive touch driver to support Microchip
CAP1114, optional hardware reset GPIO handling, and per-chip LED
constraints
- Fixes for MELFAS MMS114 touchscreen driver hardening incoming data
parsing, endianness fixes for I2C packet layout, Y-resolution
configuration, and refactoring to use chip variant descriptors
- Updates for psmouse driver resolving a potential UAF during protocol
disconnect, cleaning up PNP ID matching, and making use of guard()
- Fix for FocalTech PS/2 protocol to prevent coordinate underflow and
cursor jumps at boundaries
- A change to Synaptics driver to enable InterTouch (SMBus) mode on
Dell Inspiron 3521
- Refactoring of PA-RISC keyboard support in gscps2 to supply keymaps
via software node device properties, removing architecture-specific
tables from the generic atkbd driver
- Updates to Samsung keypad driver to keep interrupts disabled while
device is closed, along with wakeup logic cleanups and use of
pm_runtime_active guards
- Updates to NXP i.MX SNVS power key driver to report press events
during resume to avoid lost events, and error handling cleanups
- Updated TCA8418 keypad driver enabling overflow mode per hardware
errata
- Conversion of ROHM BD718x7 and BD71828 PMIC drivers to instantiate
gpio-keys child devices using software nodes instead of platform data
(coming from MFD immutable branch)
- Updates to Synaptics RMI4 driver to use touchscreen dimensions from
platform data when specified
- Firmware update speed optimization for IC Type 0x19 in ELAN I2C
driver
- A fix to Azoteq IQS5xx driver to validate firmware record spans
against programmable map size

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.
