Pull io_uring updates from Jens Axboe:
- Store ring provided buffers locally for the users, rather than stuff
them into struct io_kiocb.
These types of buffers must always be fully consumed or recycled in
the current context, and leaving them in struct io_kiocb is hence not
a good ideas as that struct has a vastly different life time.
Basically just an architecture cleanup that can help prevent issues
with ring provided buffers in the future.
- Support for mixed CQE sizes in the same ring.
Before this change, a CQ ring either used the default 16b CQEs, or it
was setup with 32b CQE using IORING_SETUP_CQE32. For use cases where
a few 32b CQEs were needed, this caused everything else to use big
CQEs. This is wasteful both in terms of memory usage, but also memory
bandwidth for the posted CQEs.
With IORING_SETUP_CQE_MIXED, applications may use request types that
post both normal 16b and big 32b CQEs on the same ring.
- Add helpers for async data management, to make it harder for opcode
handlers to mess it up.
- Add support for multishot for uring_cmd, which ublk can use. This
helps improve efficiency, by providing a persistent request type that
can trigger multiple CQEs.
- Add initial support for ring feature querying.
We had basic support for probe operations, but the API isn't great.
Rather than expand that, add support for QUERY which is easily
expandable and can cover a lot more cases than the existing probe
support. This will help applications get a better idea of what
operations are supported on a given host.
- zcrx improvements from Pavel:
- Improve refill entry alignment for better caching
- Various cleanups, especially around deduplicating normal
memory vs dmabuf setup.
- Generalisation of the niov size (Patch 12). It's still hard
coded to PAGE_SIZE on init, but will let the user to specify
the rx buffer length on setup.
- Syscall / synchronous bufer return. It'll be used as a slow
fallback path for returning buffers when the refill queue is
full. Useful for tolerating slight queue size misconfiguration
or with inconsistent load.
- Accounting more memory to cgroups.
- Additional independent cleanups that will also be useful for
mutli-area support.
- Various fixes and cleanups

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"We have GPIO awareness in the pin control core and an interesting
AAEON driver.
Core changes:
- Allow pins to be identified/marked as GPIO mode with a special
callback.
The pin controller core is now "aware" if a pin is in GPIO mode if
the callback is implemented in the driver, and can thus be marked
as "strict", i.e. disallowing simultaneous use of a line as GPIO
and another function such as I2C.
This is enabled in the Qualcomm TLMM driver and also implemeted
from day 1 in the new Broadcom STB driver
- Rename the pin config option PIN_CONFIG_OUTPUT to PIN_CONFIG_LEVEL
to better describe what the config is doing, as well as making it
more intuitive what shall be returned when reading this property
New drivers:
- Qualcomm SDM660 LPASS LPI TLMM pin controller subdriver
- Qualcomm Glymur family pin controller driver
- Broadcom STB family pin controller driver
- Tegra186 pin controller driver
- AAEON UP pin controller support.
This is some special pin controller that works as an external
advanced line MUX and amplifier for signals from an Intel SoC. A
cooperative effort with the GPIO maintainer was needed to reach a
solution where we reuse code from the GPIO aggregator/forwarder
driver
- Renesas RZ/T2H and RZ/N2H pin controller support
- Axis ARTPEC-8 subdriver for the Samsung pin controller driver
Improvements:
- Output enable (OEN) support in the Renesas RZG2L driver
- Properly support bias pull up/down in the pinctrl-single driver
- Move over all GPIO portions using generic MMIO GPIO to the new
generic GPIO chip management which has a nice and separate API
- Proper DT bindings for some older Broadcom SoCs
- External GPIO (EGPIO) support in the Qualcomm SM8250
Deleted code:
- Dropped the now unused Samsung S3C24xx drivers"

Pull IPMI updates from Corey Minyard:
"Bug fixes and enhancements for IPMI
This fixes a number of small bugs, but has some more major changes:
- Loongson-2K BMC support is added. This is an MFD device and is
dependent on the changes coming from that tree.
The way the driver handles BMCs that have become non-functional has
been completely redone. A number of changes in the past have
attempted to handle various issues around this, but nothing has
been very good. After working with some people on this, the code
has been reworked to disable the driver and fail all pending
operations if the BMC becomes non functional. It will retry the BMC
once a second to see if it's back up"

Pull spi updates from Mark Brown:
"There's one big core change in this release, Jonas Gorski has
addressed the issues with multiple chip selects which makes things
more robust and stable. Otherwise there's quite a bit of driver work,
as well as some new drivers several existing drivers have had quite a
bit of work done on them.
Possibly the most interesting thing is the VirtIO driver, this is
apparently useful for some automotive applications which want to keep
as small and robust a host system as they can, moving less critical
functionality into guests.
- James Clark has done some substantial updates on the Freescale DSPI
driver, porting in code from the BSP and building onm top of that
to fix some bugs and increase performance
- Jonas Gorski has fixed the issues with handling multple chip
selects, making things more robust and scalable
- Support for higher performance modes in the NXP FSPI driver from
Haibo Chen

has been removed from the kernel

Pull gpio updates from Bartosz Golaszewski:
"There are two new drivers and support for more models in existing
ones.
The generic GPIO API has been reworked and all users converted
which allowed us to move the fields specific to the generic GPIO
implementation out of the high-level struct gpio_chip into its own
structure that wraps the gpio_chip.
Other than that, there's nothing too exciting. Mostly minor tweaks and
fixes all over the place, some refactoring and some small new features
in helper modules.
GPIO core:
- add support for sparse pin ranges to the glue between GPIO and
pinctrl
- use a common prefix across all GPIO descriptor flags for improved
namespacing
New drivers:
- add new GPIO driver for the Nuvoton NCT6694
- add new GPIO driver for MAX7360
Driver improvements:
- add support for Tegra 256 to the gpio-tegra186 driver
- add support for Loongson-2K0300 to the gpio-loongson-64bit driver
- refactor the gpio-aggregator module to expose its GPIO forwarder
API to other in-kernel users (to enable merging of a new pinctrl
driver that uses it)
- convert all remaining drivers to using the modernized generic GPIO
chip API and remove the old interface
- stop displaying global GPIO numbers in debugfs output of controller
drivers
- extend the gpio-regmap helper with a new config option and improve
its support for GPIO interrupts
- remove redundant fast_io parameter from regmap configs in GPIO
drivers that already use MMIO regmaps which imply it
- add support for a new model in gpio-mmio: ixp4xx expansion bus
- order includes alphabetically in a few drivers for better
readability
- use generic device properties where applicable
- use devm_mutex_init() where applicable
- extend build coverage of drivers by enabling more to be compiled
with COMPILE_TEST enabled
- allow building gpio-stmpe as a module
- use dev_err_probe() where it makes sense in drivers
Late driver fixes:
- fix setting GPIO direction to output in gpio-mpfs
Documentation:
- document the usage of software nodes with GPIO chips
Device-tree bindings:
- Add DT bindings documents for new hardware: Tegra256, MAX7360
- Document a new model in Loongson bindings: LS2K0300
- Document a new model using the generic GPIO binding: IXP4xx
- Convert the DT binding for fsl,mxs-pinctrl to YAML
- fix the schema ID in the "trivial" GPIO schema

Commit a755d0e2d41b ("cpufreq: Honour transition_latency over
transition_delay_us") caused platforms where cpuinfo.transition_latency
is CPUFREQ_ETERNAL to get a very large transition latency whereas
previously it had been capped at 10 ms (and later at 2 ms).
This led to a user-observable regression between 6.6 and 6.12 as
described by Shawn:
"The dbs sampling_rate was 10000 us on 6.6 and suddently becomes
6442450 us (4294967295 / 1000 * 1.5) on 6.12 for these platforms
because the default transition delay was dropped [...].
It slows down dbs governor's reacting to CPU loading change
dramatically. Also, as transition_delay_us is used by schedutil
governor as rate_limit_us, it shows a negative impact on device
idle power consumption, because the device gets slightly less time
in the lowest OPP."
Evidently, the expectation of the drivers using CPUFREQ_ETERNAL as
cpuinfo.transition_latency was that it would be capped by the core,
but they may as well return a default transition latency value instead
of CPUFREQ_ETERNAL and the core need not do anything with it.
Accordingly, introduce CPUFREQ_DEFAULT_TRANSITION_LATENCY_NS and make
all of the drivers in question use it instead of CPUFREQ_ETERNAL. Also
update the related Rust binding.

Lacking the support of device specific mapping supported in virtio,
VDUSE must trick the DMA API in order to make virtio-vdpa transport
work. This is done by advertising vDPA device as dma device with a
VDUSE specific dma_ops even if it doesn't do DMA at all.
This will be fixed by this patch. Thanks to the new mapping operations
support by virtio and vDPA. VDUSE can simply switch to advertise its
specific mappings operations to virtio via virtio-vdpa then DMA API is
not needed for VDUSE any more and iova domain could be used as the
mapping token instead.

This patch introduces map operations for virtio device. Virtio used to
use DMA API which is not necessarily the case since some devices
doesn't do DMA. Instead of using tricks and abusing DMA API, let's
simply abstract the current mapping logic into a virtio specific
mapping operations. For the device or transport that doesn't do DMA,
they can implement their own mapping logic without the need to trick
DMA core. In this case the mapping metadata is opaque to the virtio
core that will be passed back to the transport or device specific map
operations. For other devices, DMA API will still be used, so map
token will still be the dma device to minimize the changeset and
performance impact.
The mapping operations are abstracted as a independent structure
instead of reusing virtio_config_ops. This allows the transport can
simply reuse the structure for lower layers like vDPA.
A set of new mapping helpers were introduced for the device that want
to do mapping by themselves.

Following patch will introduce the mapping operations for virtio

needs to support a transport or device specific mapping metadata as well.
So this patch introduces a union container of a dma device. The idea
is the allow the transport layer to pass device specific mapping
metadata which will be used as a parameter for the virtio mapping
operations. For the transport or device that is using DMA, dma device
is still being used.

Pull irq chip driver updates from Thomas Gleixner:
- Use the startup/shutdown callbacks for the PCI/MSI per device
interrupt domains.
This allows us to initialize the RISCV PLIC interrupt hierarchy
correctly and provides a mechanism to decouple the masking and
unmasking during run-time from the expensive PCI mask and unmask when
the underlying MSI provider implementation allows the interrupt to be
masked.
- Initialize the RISCV PLIC MSI interrupt hierarchy correctly so that
the affinity assignment works correctly by switching it over to the
startup/shutdown scheme
- Allow MSI providers to opt out from masking a PCI/MSI interrupt at
the PCI device during operation when the provider can mask the
interrupt at the underlying interrupt chip. This reduces the overhead
in scenarios where disable_irq()/enable_irq() is utilized frequently
by a driver.
The PCI/MSI device level [un]masking is only required on startup and
shutdown in this case.
- Remove the conditional mask/unmask logic in the PCI/MSI layer as this
is now handled unconditionally.
- Replace the hardcoded interrupt routing in the Loongson EIOINTC
interrupt driver to respect the firmware settings and spread them out
to different CPU interrupt inputs so that the demultiplexing handler
only needs to read only a single 64-bit status register instead of
four, which significantly reduces the overhead in VMs as the status
register access causes a VM exit.
- Add support for the new AST2700 SCU interrupt controllers
- Use the legacy interrupt domain setup for the Loongson PCH-LPC
interrupt controller, which resembles the x86 legacy PIC setup and
has the same hardcoded legacy requirements.

Move KVM's morphing of pending signals into userspace exits into KVM
proper, and drop the @vcpu param from xfer_to_guest_mode_handle_work().
How KVM responds to -EINTR is a detail that really belongs in KVM itself,
and invoking kvm_handle_signal_exit() from kernel code creates an inverted
module dependency. E.g. attempting to move kvm_handle_signal_exit() into
kvm_main.c would generate an linker error when building kvm.ko as a module.
Dropping KVM details will also converting the KVM "entry" code into a more
generic virtualization framework so that it can be used when running as a
Hyper-V root partition.
Lastly, eliminating usage of "struct kvm_vcpu" outside of KVM is also nice
to have for KVM x86 developers, as keeping the details of kvm_vcpu purely
within KVM allows changing the layout of the structure without having to
boot into a new kernel, e.g. allows rebuilding and reloading kvm.ko with a
modified kvm_vcpu structure as part of debug/development.

symbols when compiled with -fno-common.
Mark them as 'extern' to convert them from weak symbol definitions
to weak symbol references. That works with static and dynamic
linkage independent of -fcommon and -fno-common"

Pull x86 SEV and apic updates from Borislav Petkov:
- Add functionality to provide runtime firmware updates for the non-x86
parts of an AMD platform like the security processor (ASP) firmware,
modules etc, for example. The intent being that these updates are
interim, live fixups before a proper BIOS update can be attempted
- Add guest support for AMD's Secure AVIC feature which gives encrypted
guests the needed protection against a malicious hypervisor
generating unexpected interrupts and injecting them into such guest,
thus interfering with its operation in an unexpected and negative
manner.
The advantage of this scheme is that the guest determines which
interrupts and when to accept them vs leaving that to the benevolence
(or not) of the hypervisor
- Strictly separate the startup code from the rest of the kernel where
former is executed from the initial 1:1 mapping of memory.
The problem was that the toolchain-generated version of the code was
being executed from a different mapping of memory than what was
"assumed" during code generation, needing an ever-growing pile of
fixups for absolute memory references which are invalid in the early,
1:1 memory mapping during boot.
The major advantage of this is that there's no need to check the 1:1
mapping portion of the code for absolute relocations anymore and get
rid of the RIP_REL_REF() macro sprinkling all over the place.
For more info, see Ard's very detailed writeup on this [1]

Pull x86 resource control updates from Borislav Petkov:
"Add support on AMD for assigning QoS bandwidth counters to resources
(RMIDs) with the ability for those resources to be tracked by the
counters as long as they're assigned to them.
Previously, due to hw limitations, bandwidth counts from untracked
resources would get lost when those resources are not tracked.
Refactor the code and user interfaces to be able to also support
other, similar features on ARM, for example"

Add nfsd_file_dio_alignment and use it to avoid issuing misaligned IO
using O_DIRECT. Any misaligned DIO falls back to using buffered IO.
Because misaligned DIO is now handled safely, remove the nfs modparam
'localio_O_DIRECT_semantics' that was added to require users opt-in to
the requirement that all O_DIRECT be properly DIO-aligned.
Also, introduce nfs_iov_iter_aligned_bvec() which is a variant of
iov_iter_aligned_bvec() that also verifies the offset associated with
an iov_iter is DIO-aligned. NOTE: in a parallel effort,
iov_iter_aligned_bvec() is being removed along with
iov_iter_is_aligned().
Lastly, add pr_info_ratelimited if underlying filesystem returns
-EINVAL because it was made to try O_DIRECT for IO that is not
DIO-aligned (shouldn't happen, so its best to be louder if it does).
