Pull regulator updates from Mark Brown:
"There's one API update here, a new API factoring out a common pattern
for reference voltage supplies. These are supplies used as a reference
by analogue circuits where the consumer requests and enables the
supply, reads the voltage to calibrate the user and then never touches
it again. This is factored out into a single operation which just
returns the voltage and uses devm_ to manage the request and enable
portion.
Otherwise this has been a very quiet release, we've got some new
device support, some small fixes, housekeeping and cleanup work but
nothing substantial.
There's also some non-regulator changes in here, a number of users for
the new reference voltage API were merged along with it and some MFD
changes were pulled in as dependencies for new driver work.
Highlights:
- Add a new API for single operation handling of reference voltages
- Support for Allwinner AXP717 and D1, and NXP PCA9561A"

Pull thermal control updates from Rafael Wysocki:
"The most significant part of this is a rework of thermal governors,
including a redesign of the thermal governor interface and changes to
make some of them take trip point hysteresis into account properly, as
well as some related cleanups of the thermal governors and thermal
core.
The above is based on preliminary changes refactoring thermal data
structures and moving the definitions of some of them into the thermal
core which also ensure that trip point crossing notifications will be
sent to user space via netlink and recorded in the debug statistics in
temperature order.
In addition, netlink bind/unbind notifications are added to the
thermal core and the Intel HFI driver is modified to use them to avoid
sending netlink messages until there are subscribers.
Apart from that, multiple thermal drivers are updated which includes
new hardware support (MediaTek MT8188 and MT8186, Amlogic A1 thermal
sensor, Loongson-2K2000, Lmh QCM2290), fixes, cleanups and
documentation updates, and the recently added thermal debug code is
fixed and cleaned up.
Specifics:
- Redesign the thermal governor interface to allow the governors to
work in a more straightforward way (Rafael Wysocki)
- Make thermal governors take the current trip point thresholds into
account in their computations which allows trip hysteresis to be
observed more accurately (Rafael Wysocki)
- Make the thermal core manage passive polling for thermal zones and
remove passive polling management from thermal governors (Rafael
Wysocki)
- Refactor trip point representation and move the definition of
thermal governor and thermal zone device structures to the thermal
core (Rafael Wysocki)
- Sort trip point crossing notifications and debug recording of trip
point crossing events by temperature (Rafael Wysocki)
- Improve the handling of cooling device states and thermal
mitigation episodes in progress in the thermal debug code (Rafael
Wysocki)
- Avoid excessive updates of trip point statistics and clean up the
printing of thermal mitigation episode information (Rafael Wysocki)
- Clean up thermal governors and thermal core (Rafael Wysocki)
- Allow thermal drivers to register notifiers that will be invoked on
netlink events like BIND and UNBIND, so that they can adjust their
activity depending on whether or not there are any subscribers of
netlink messages coming from them, and make the Intel HFI driver
use this mechanism (Stanislaw Gruszka)
- Adjust the update delay and capabilities-per-event values in the
Intel HFI thermal driver to prevent it from missing events and
allow it to process more data in one go (Ricardo Neri)
- Add missing MODULE_DESCRIPTION() to multiple files in the
int340x_thermal and intel_soc_dts_iosf drivers (Srinivas
Pandruvada)
- Replace deprecated strncpy() with strscpy() in the int340x_thermal
driver (Justin Stitt)
- Add QCM2290 compatible DT bindings for Lmh and fix a NULL pointer
dereference in the lmh driver when the SCM is not present (Konrad
Dybcio)
- Use the strreplace() function instead of doing it manually in the
Armada driver (Rasmus Villemoes)
- Convert st,stih407-thermal to DT schema and fix up missing
properties (Raphael Gallais-Pou)
- Add suspend/resume by restoring the context of the tsens sensor
(Priyansh Jain)
- Support A1 SoC family Thermal Sensor controller and add the DT
bindings (Dmitry Rokosov)
- Improve the temperature approximation calculation and consolidate
the Tj constant into a shared area of the structure instead of
duplicating it on the Rcar Gen3 (Niklas Söderlund)
- Fix the Mediatek LVTS sensor coefficient for the MT8192 in order to
support it correctly (Hsin-Te Yuan)
- Fix a NULL pointer dereference in the tsens driver when the
function compute_intercept_slope() is called with a NULL parameter
(Aleksandr Mishin)
- Remove some unused fields in struct qpnp_tm_chip and k3_bandgap
(Christophe Jaillet)
- Fix up calibration efuse data decoding, consolidate the code by
checking boundaries and refactor some part of the LVTS Mediatek
driver. After setting the scene, add MT8186 and MT8188 along with
the DT bindings (Nicolas Pitre)
- Add Loongson-2K2000 support after some minor code adjustements and
providing the DT bindings definition (Binbin Zhou)"

git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux
Pull sh updates from John Paul Adrian Glaubitz:
"The majority of improvements are coming from Geert Uytterhoeven who
took the time to fix a total of 30 cases of "-Wmissing-prototypes"
compiler warnings, either by adding a missing header include, defining
the missing forward declarations or making the functions in question
static.
In the case of several DMA functions, the fix was to actually just
remove them as they were added but never used. Another one of these
warnings was eliminated by removing the left-over sh5 cache handling
support, a change that was suggested by Yoshinori Sato and, finally,
the last of these warnings was fixed by guarding the function
setup_profiling_timer() with CONFIG_PROFILING.
While at it, Geert also removed two unneeded casts to kprobe_opcode_t
in the kprobes code.
Another change was contributed by Guenter Roeck to fix errors that
were reported during checksum unit tests. The fix actually reverts the
older change cadc4e1a2b4d ("sh: Handle calling csum_partial with
misaligned data") which turned to be incorrect. It remains to be
investigated whether there is a better way to handle misaligned data
in csum_partial().
A small fix contributed by Krzysztof Kozlowski drops the incorrect SPI
controller spi-max-frequency property in the device tree source file
for the J2 device platform while Uwe Kleine-König converted the
push-switch driver to have its callback function return void, a change
that is currently being applied to all drivers throughout the kernel
in order to avoid resource leaks.
Last but not least, Artur Rojek has fixed the IOPORT base address for
the Sega Dreamcast platform which allows the Linux kernel to be
successfully booted on this once popular video game console for the
first time since a long time ago"

Pull x86 interrupt handling updates from Thomas Gleixner:
"Add support for posted interrupts on bare metal.
Posted interrupts is a virtualization feature which allows to inject
interrupts directly into a guest without host interaction. The VT-d
interrupt remapping hardware sets the bit which corresponds to the
interrupt vector in a vector bitmap which is either used to inject the
interrupt directly into the guest via a virtualized APIC or in case
that the guest is scheduled out provides a host side notification
interrupt which informs the host that an interrupt has been marked
pending in the bitmap.
This can be utilized on bare metal for scenarios where multiple
devices, e.g. NVME storage, raise interrupts with a high frequency. In
the default mode these interrupts are handles independently and
therefore require a full roundtrip of interrupt entry/exit.
Utilizing posted interrupts this roundtrip overhead can be avoided by
coalescing these interrupt entries to a single entry for the posted
interrupt notification. The notification interrupt then demultiplexes
the pending bits in a memory based bitmap and invokes the
corresponding device specific handlers.
Depending on the usage scenario and device utilization throughput
improvements between 10% and 130% have been measured.
As this is only relevant for high end servers with multiple device
queues per CPU attached and counterproductive for situations where
interrupts are arriving at distinct times, the functionality is opt-in
via a kernel command line parameter"

Pull interrupt subsystem updates from Thomas Gleixner:
"Core code:
- Interrupt storm detection for the lockup watchdog:
Lockups which are caused by interrupt storms are not easy to debug
because there is no information about the events which make the
lockup detector trigger.
To make this more user friendly, provide an extenstion to interrupt
statistics which allows to take snapshots and an interface to
retrieve the delta to the snapshot. Use this new mechanism in the
watchdog code to do a two stage lockup analysis by taking the
snapshot and printing the deltas for the topmost active interrupts
on the second trigger.
Note: This contains both the interrupt and the watchdog changes as
the latter depend on the former obviously.
- Avoid summation loops in the /proc/interrupts output and use the
global counter when possible
- Skip suspended interrupts on CPU hotplug operations to ensure that
they are not delivered before the system resumes the device drivers
when coming out of suspend.
- On CPU hot-unplug interrupts which are affine to the outgoing CPU
are migrated to a different CPU in the affinity mask. This can fail
when the CPUs have no vectors left. Instead of giving up try to
migrate it to any online CPU and thereby breaking the affinity
setting in order to prevent a stale device interrupt which targets
an offline CPU
- The usual small cleanups
Driver code:
- Support for the RISCV AIA MSI controller
- Make the interrupt allocation for the Loongson PCH controller more
flexible to prevent vector exhaustion

Pull x86 timers update from Thomas Gleixner:
"A single update for the TSC synchronixation sanity checks:
The sad state of TSC being notoriously non-sychronized for several
decades caused the kernel to grow quite rigorous sanity checks to
detect whether the TSC is valid to be used for timekeeping.
The TSC ADJUST MSR provides the offset between the initial TSC value
after hardware reset and later modifications. This allows to detect
cases where firmware tampers with the TSC and also allows to correct
the firmware induced damage by resetting the offset in a controlled
way.
The universal correct rule is that the TSC ADJUST value has to be
consistent within all CPUs of a socket.
The kernel further assumes that the TSC offset should be consistent
between sockets. That's not really correct as systems with a huge
number of sockets are not architecurally guaranteed to reset the per
socket TSC base synchronously.
In case that the per socket offset is not consistent the kernel resets
it to the offset of the boot CPU and then does a synchronization check
which corrects for the inter socket delays.
That works most of the time, but it is suboptimal as the firmware has
eventually better information about the per socket offset and on sane
systems that offset should just work in the validation checks"

Pull timers and timekeeping updates from Thomas Gleixner:
"Core code:
- Make timekeeping and VDSO time readouts resilent against math
overflow:
In guest context the kernel is prone to math overflow when the host
defers the timer interrupt due to overload, malfunction or malice.
This can be mitigated by checking the clocksource delta for the
maximum deferrement which is readily available. If that value is
exceeded then the code uses a slowpath function which can handle
the multiplication overflow.
This functionality is enabled unconditionally in the kernel, but
made conditional in the VDSO code. The latter is conditional
because it allows architectures to optimize the check so it is not
causing performance regressions.
On X86 this is achieved by reworking the existing check for
negative TSC deltas as a negative delta obviously exceeds the
maximum deferrement when it is evaluated as an unsigned value. That
avoids two conditionals in the hotpath and allows to hide both the
negative delta and the large delta handling in the same slow path.

Pull DSA and IAA accelerator mis-alignment fix from Arjan van de Ven:
"The DSA (memory copy/zero/etc) and IAA (compression) accelerators in
the Sapphire Rapids and Emerald Rapids SOCs turn out to have a bug
that has security implications.
Both of these accelerators work by the application submitting a 64
byte command to the device; this command contains an opcode as well as
the virtual address of the return value that the device will update on
completion... and a set of opcode specific values.
In a typical scenario a ring 3 application mmaps the device file and
uses the ENQCMD or MOVDIR64 instructions (which are variations of a 64
byte atomic write) on this mmap'd memory region to directly submit
commands to a device hardware.
The return value as specified in the command, is supposed to be 32 (or
64) bytes aligned in memory, and generally the hardware checks and
enforces this alignment.
However in testing it has been found that there are conditions
(controlled by the submitter) where this enforcement does not
happen... which makes it possible for the return value to span a page
boundary. And this is where it goes wrong - the accelerators will
perform the virtual to physical address lookup on the first of the two
pages, but end up continue writing to the next consecutive physical
(host) page rather than the consecutive virtual page. In addition, the
device will end up in a hung state on such unaligned write of the
return value.
This patch series has the proposed software side solution consisting
of three parts:
- Don't allow these two PCI devices to be assigned to VM guests (we
cannot trust a VM guest to behave correctly and not cause this
condition)
- Don't allow ring 3 applications to set up the mmap unless they have
CAP_SYS_RAWIO permissions. This makes it no longer possible for
non-root applications to directly submit commands to the
accelerator
- Add a write() method to the device so that an application can
submit its commands to the kernel driver, which performs the needed
sanity checks before submitting it to the hardware.
This switch from mmap to write is an incompatible interface change to
non-root userspace, but we have not found a way to avoid this. All
software we know of uses a small set of accessor libraries for these
accelerators, for which libqpl and libdml (on github) are the most
common. As part of the security release, updated versions of these
libraries will be released that transparently fall back to write().
Intel has assigned CVE-2024-21823 to this hardware issue"

Pull Rust updates from Miguel Ojeda:
"The most notable change is the drop of the 'alloc' in-tree fork. This
is nicely reflected in the diffstat as a ~10k lines drop. In turn,
this makes the version upgrades way simpler and smaller in the future,
e.g. the latest one in commit 56f64b370612 ("rust: upgrade to Rust
1.78.0").
More importantly, this increases the chances that a newer compiler
version just works, which in turn means supporting several compiler
versions is easier now. Thus we will look into finally setting a
minimum version in the near future.
Toolchain and infrastructure:
- Upgrade to Rust 1.78.0
This time around, due to how the kernel and Rust schedules have
aligned, there are two upgrades in fact. These allow us to remove
one more unstable feature ('offset_of') from the list, among other
improvements
- Drop 'alloc' in-tree fork of the standard library crate, which
means all the unstable features used by 'alloc' (~30 language ones,
~60 library ones) are not a concern anymore
- Support DWARFv5 via the '-Zdwarf-version' flag
- Support zlib and zstd debuginfo compression via the
'-Zdebuginfo-compression' flag
'kernel' crate:
- Support allocation flags ('GFP_*'), particularly in 'Box' (via
'BoxExt'), 'Vec' (via 'VecExt'), 'Arc' and 'UniqueArc', as well as
in the 'init' module APIs
- Remove usage of the 'allocator_api' unstable feature
- Remove 'try_' prefix in allocation APIs' names
- Add 'VecExt' (an extension trait) to be able to drop the 'alloc'
fork
- Add the '{make,to}_{upper,lower}case()' methods to 'CStr'/'CString'
- Add the 'as_ptr' method to 'ThisModule'
- Add the 'from_raw' method to 'ArcBorrow'
- Add the 'into_unique_or_drop' method to 'Arc'
- Display column number in the 'dbg!' macro output by applying the
equivalent change done to the standard library one
- Migrate 'Work' to '#[pin_data]' thanks to the changes in the
'macros' crate, which allows to remove an unsafe call in its 'new'
associated function
- Prevent namespacing issues when using the '[try_][pin_]init!'
macros by changing the generated name of guard variables
- Make the 'get' method in 'Opaque' const
- Implement the 'Default' trait for 'LockClassKey'
- Remove unneeded 'kernel::prelude' imports from doctests
- Remove redundant imports
'macros' crate:
- Add 'decl_generics' to 'parse_generics()' to support default
values, and use that to allow them in '#[pin_data]'
Helpers:
- Trivial English grammar fix
Documentation:
- Add section on Rust Kselftests to the 'Testing' document
- Expand the 'Abstractions vs. bindings' section of the 'General
Information' document"

Pull io_uring updates from Jens Axboe:
- Greatly improve send zerocopy performance, by enabling coalescing of
sent buffers.
MSG_ZEROCOPY already does this with send(2) and sendmsg(2), but the
io_uring side did not. In local testing, the crossover point for send
zerocopy being faster is now around 3000 byte packets, and it
performs better than the sync syscall variants as well.
This feature relies on a shared branch with net-next, which was
pulled into both branches.
- Unification of how async preparation is done across opcodes.
Previously, opcodes that required extra memory for async retry would
allocate that as needed, using on-stack state until that was the
case. If async retry was needed, the on-stack state was adjusted
appropriately for a retry and then copied to the allocated memory.
This led to some fragile and ugly code, particularly for read/write
handling, and made storage retries more difficult than they needed to
be. Allocate the memory upfront, as it's cheap from our pools, and
use that state consistently both initially and also from the retry
side.
- Move away from using remap_pfn_range() for mapping the rings.
This is really not the right interface to use and can cause lifetime
issues or leaks. Additionally, it means the ring sq/cq arrays need to
be physically contigious, which can cause problems in production with
larger rings when services are restarted, as memory can be very
fragmented at that point.
Move to using vm_insert_page(s) for the ring sq/cq arrays, and apply
the same treatment to mapped ring provided buffers. This also helps
unify the code we have dealing with allocating and mapping memory.
Hard to see in the diffstat as we're adding a few features as well,
but this kills about ~400 lines of code from the codebase as well.
- Add support for bundles for send/recv.
When used with provided buffers, bundles support sending or receiving
more than one buffer at the time, improving the efficiency by only
needing to call into the networking stack once for multiple sends or
receives.
- Tweaks for our accept operations, supporting both a DONTWAIT flag for
skipping poll arm and retry if we can, and a POLLFIRST flag that the
application can use to skip the initial accept attempt and rely
purely on poll for triggering the operation. Both of these have
identical flags on the receive side already.
- Make the task_work ctx locking unconditional.
We had various code paths here that would do a mix of lock/trylock
and set the task_work state to whether or not it was locked. All of
that goes away, we lock it unconditionally and get rid of the state
flag indicating whether it's locked or not.
The state struct still exists as an empty type, can go away in the
future.
- Add support for specifying NOP completion values, allowing it to be
used for error handling testing.
- Use set/test bit for io-wq worker flags. Not strictly needed, but
also doesn't hurt and helps silence a KCSAN warning.
- Cleanups for io-wq locking and work assignments, closing a tiny race
where cancelations would not be able to find the work item reliably.

we should aim to get rid of f_op->read() at some point.
Aside from that io_uring and others want to mark files as FMODE_NOWAIT
so it can make use of per-IO nonblocking hints to enable more
efficient IO. Converting those users to f_op->read_iter() allows them
to be marked with FMODE_NOWAIT"
