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.

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

Pull audit updates from Paul Moore:
- Drop BUG_ON() assertions from two functions
While I don't recall any bug reports from either of these assertions
in recent memory, neither of these checks warrant the kernel panic
that could result from BUG_ON(). One of the BUG_ON() calls is
converted to a WARN_ON_ONCE() and the other to a lockdep assertion.
- Fix an audit tree reference counting problem
Fix a corner case where audit could end up unintentionally dropping
the last reference to an audit tree while the tree was still in use.
We should probably revisit the audit tree handling code in full, but
this patch works, and should be easy to backport to stable trees and
downstream kernels.

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.

Pull Real-time Verifier updates from Steven Rostedt:
- Switch LTL and DOT parsers to Lark in code generation tool
The rvgen code generation tool originally parsed DOT files and LTL
specifications using custom string parsing and Ply, which is no
longer maintained. The DOT parser was fragile and prone to failure on
minor format variations. Both LTL and DOT parsers have been rewritten
to use the Lark parsing library.
- Simplify Hybrid Automata clock variables
The clock variables in hybrid automata monitors now use a single
representation of the elapsed time since the clock was reset, rather
than converting between invariant and guard representations. This
allows simpler code generation for the newly refactored parser.
- Generate cleanup hook for per-obj monitor
The code generation scripts now adds a cleanup function to per-obj
monitors for the user to wire to the appropriate event (e.g.
sched_process_exit for tasks).
- Reduce read_lock scope during per-task cleanup
Take the tasklist_lock only when necessary, that is when iterating
over for_each_process_thread().
- Simplify task monitor slot management
Only rely on the slot array for per-task slot management to avoid
inconsistency with the unused counter.
- Improve rvgen code robustness and templates
Use pathlib in rvgen and improve kernel path discovery. Also improve
consistency across templates when generating code (e.g. author
placeholder and monitor struct name).
- Update rtapp sleep monitor
Simplify the sleep monitor by excluding kernel threads and updating
the nanosleep check to focus only on CLOCK_REALTIME. Also switch to
use the sched_exit tracepoint to run in the context of the offending
(wakee) task.
- Add wakeup monitor
Add the new rtapp/wakeup monitor to detect when lower-priority tasks
wake up higher-priority ones, complementing the existing sleep
monitor by running in the waker context and capturing its stack
trace.
- Fix tools/rv exit status on failure
Ensure the rv tool returns a failure exit code when a monitor fails
to start because it was already running.
- Add automated selftests for tools/rv and rvgen
Introduced automated bash selftests to validate rv monitor listing
and execution under different configurations. Added tests for the
rvgen code generator, validating generated files against expected
output (golden). Tests are reachable via make check.
- Add KUnit test coverage for verification monitors
Added comprehensive KUnit tests to validate the functionality of
deterministic, hybrid, and LTL monitors by emulating event sequences
and timing in a mock environment without affecting the running kernel
while expecting mock reactions to fire. Ensure real RV monitors
cannot run during KUnit tests to avoid state corruption.
- Mock current in rv monitors
Mock the call to current in rv monitors when the KUnit tests are
built to allow them to run the test on dummy tasks. No overhead is
expected when KUnit tests aren't running.
- Introduce rvgen kunit subcommand
Added a new 'kunit' subcommand to rvgen to automatically patch an
already generated monitor with KUnit integration templates by parsing
its event handlers and creating the required mock structures and
initializations.
- Refine kernel verification selftests
Added new selftests for the deadline and stall monitors and
rearranged the existing wwnr_printk test to resolve flakiness.
Additionally, fixed an issue in the selftests framework where
negative assertion failures were not correctly propagated due to
shell rules.
- Fix 32-bit build of nomiss KUnit test
A previous commit introduced a division between an u64 and a constant
value and that doesn't build on 32-bit systems. Use div_u64()
instead.
- Document changes in sleep monitor
The sleep monitor introduced some changes in the past like allowing
epoll_wait() as a valid sleep and a task going to runnable before
scheduling as a valid wakeup. Document both.

GICv5 supports up to 128 PPIs, but KVM currently implements only the
first 64, which contain the architected PPIs it supports.
An encoded PPI with an ID outside that range passes irq_is_ppi(),
which only checks the encoded interrupt type. vgic_get_vcpu_irq()
therefore looks it up in private_irqs[], where array_index_nospec()
clamps the out-of-range index to zero and aliases PPI 0.
Include the supported PPI range in irq_is_ppi() so that KVM interfaces
reject unsupported PPIs. Also reject an out-of-range PPI in the lookup
as a safeguard against callers bypassing the predicate.
Fixes: 4d591252bacb ("KVM: arm64: gic-v5: Implement PPI interrupt injection")
Fixes: eb8bce08ecb1 ("KVM: arm64: gic: Introduce interrupt type helpers")

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

expansion headers since SPI devices need to be manually specified. We
also have support for the DQS signal on higher end flash devices.

Implement suspend operation for vduse devices, so vhost-vdpa will offer
that backend feature and userspace can effectively suspend the device.
This is a must before get virtqueue indexes (base) for live migration,
since the device could modify them after userland gets them.
This patch does not implement resume, so VMM resets the whole device
to recover from a live migration failure. Resume optimization can be
implemented on top of these patches, as other vDPA devices have done in
the past.

Add the VDUSE_F_QUEUE_READY feature flag. This allows the kernel module
to explicitly signal userspace when a specific virtqueue has been
enabled.

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.

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.
- Update email address for Tomasz Duszynski and re-add Tomasz to
various maintainer entries.
Docs

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

- Switch to devm helpers which simplified code and closed a resource leak.
ti,opt3001
- Split complicated opt3001_get_processed() logic into irq an no irq
helper functions.
- Use devm to simplify code.

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
interfaces to descriptors, a patch to restore little-endian mode on
the one Arm platform (ixp4xx) that only worked in big-endian mode
recently, and some minor cleanups and bugfixes"

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
- 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"
