Keep bio_iov_iter_get_bdev_pages local with the callers, as blindly
looking at the bdev logical block size is often not the best idea
unless on a block device.

Now that the bio_iov_iter_get_pages is free again, use it instead of
the more complicated now. Also drop the unused export.

>From commit 074a7aca7afa ("block: move stats from disk to part0"),
we know that:
* {disk|all}_stat_*() are gone.
* disk_stat_lock/unlock() are renamed to part_stat_lock/unlock().
Therefore, outdated comments should be updated accordingly.
Fixes: 074a7aca7afa ("block: move stats from disk to part0")

Pull block updates from Jens Axboe:
- NVMe pull request via Keith:
- FC target fixes (Daniel)
- Authentication fixes and updates (Martin, Chris)
- Admin controller handling (Kamaljit)
- Target lockdep assertions (Max)
- Keep-alive updates for discovery (Alastair)
- Suspend quirk (Georg)
- MD pull request via Yu:
- Add support for a lockless bitmap.
A key feature for the new bitmap are that the IO fastpath is
lockless. If a user issues lots of write IO to the same bitmap
bit in a short time, only the first write has additional overhead
to update bitmap bit, no additional overhead for the following
writes.
By supporting only resync or recover written data, means in the
case creating new array or replacing with a new disk, there is no
need to do a full disk resync/recovery.
- Switch ->getgeo() and ->bios_param() to using struct gendisk rather
than struct block_device.
- Rust block changes via Andreas. This series adds configuration via
configfs and remote completion to the rnull driver. The series also
includes a set of changes to the rust block device driver API: a few
cleanup patches, and a few features supporting the rnull changes.
The series removes the raw buffer formatting logic from
`kernel::block` and improves the logic available in `kernel::string`
to support the same use as the removed logic.
- floppy arch cleanups
- Reduce the number of dereferencing needed for ublk commands
- Restrict supported sockets for nbd. Mostly done to eliminate a class
of issues perpetually reported by syzbot, by using nonsensical socket
setups.
- A few s390 dasd block fixes
- Fix a few issues around atomic writes
- Improve DMA interation for integrity requests
- Improve how iovecs are treated with regards to O_DIRECT aligment
constraints.
We used to require each segment to adhere to the constraints, now
only the request as a whole needs to.
- Clean up and improve p2p support, enabling use of p2p for metadata
payloads
- Improve locking of request lookup, using SRCU where appropriate
- Use page references properly for brd, avoiding very long RCU sections
- Fix ordering of recursively submitted IOs
- Clean up and improve updating nr_requests for a live device
- Various fixes and cleanups

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.

Pull kunit updates from Shuah Khan:
- New parameterized test features
KUnit parameterized tests supported two primary methods for getting
parameters:
- Defining custom logic within a generate_params() function.
- Using the KUNIT_ARRAY_PARAM() and KUNIT_ARRAY_PARAM_DESC() macros
with a pre-defined static array and passing the created
*_gen_params() to KUNIT_CASE_PARAM().
These methods present limitations when dealing with dynamically
generated parameter arrays, or in scenarios where populating
parameters sequentially via generate_params() is inefficient or
overly complex.
These limitations are fixed with a parameterized test method
- Fix issues in kunit build artifacts cleanup
- Fix parsing skipped test problem in kselftest framework
- Enable PCI on UML without triggering WARN()

Pull SoC dt updates from Arnd Bergmann:
"There are five sets of new SoCs that get added in existing families,
all of them being either upgrades or cut-down versions of the older
chips:
- Apple M2 Pro, M2 Max and M2 Ultra, used in the 2022/2023 generation
of high-end workstations and laptops from Apple. Linux has been
working on these for a while but stil requires patches.
- Axis Artpec8 is an Armv8 chip based on Samsung Exynos design,
unlike the earlier Armv7 Artpec6 from the same company that was
part of a separate family of chips.
- NXP i.MX91 is a cut-down version of i.MX93, using only a single
Cortex-A55 core.
- Qualcomm Lemans Auto is a variant of the Lemans SoC that was
originally merged under the sa8775p name, the differences being
mostly the firmware configuration of the platform.
- Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44),
RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial
bedded SoCs based on Cortex-A55 cores
In total, there are 65 new machines, including:
- Industrial embedded system and single-board computers based on NXP,
Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips.
- Reference boards for the newly added Renesas, Qualcomm, NXP and
Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC
- Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1
chips.
- Several Samsung phones using Qualcomm Snapdragon chips
- Set-top boxes based on Allwinner H313
- Five BMC boards using 32-bit ASpeed SoCs
- Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708
(ARMv7) SoCs
Two machines get phased out because they were available only in small
quantities but never made it into products: one STi407 based reference
board, and a Snapdragon 845 based Chromebook.
Aside from the newly added machines, a lot of work went into improving
hardware support on the existing machines and cleaning up contents for
validation"

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"

"Bug fixes and enhancements for IPMI

- Loongson-2K BMC support is added. This is an MFD device and is

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

Pull MFD updates from Lee Jones:
"This round of updates contains a fair amount of new device support, a
couple of fixes and some refactoring. The most notable additions
include new drivers for Loongson's Security Engine, RNG and TPM, new
drivers for TI's TPS6594 Power Button and BQ257xx Charger ICs.
The rest of the set provides a return value check fix and a
refactoring to use a more modern GPIO API for the VEXPRESS sysreg
driver, the removal of a deprecated IRQ ACK function from the MC13xxx
RTC driver and a new DT binding for the aforementioned TI BQ257xx
charger.
New Support & Features:
- Add a suite of drivers for the Loongson Security Engine, including
the core controller, a Random Number Generator (RNG) and Trusted
Platform Module (TPM) support.

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
- Removal of the obsolete S3C2443 driver, the underlying SoC support
has been removed from the kernel
- Support for Amlogic AL113L2, Atmel SAMA7D65 and SAM9x7 and for

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
- describe GPIO hogs in the generic GPIO binding"

Relying on other components to include those basic types is unreliable
and may cause compile errors like:
../include/linux/mfd/qnap-mcu.h:13:9: error: unknown type name ‘u32’
13 | u32 baud_rate;
| ^~~
../include/linux/mfd/qnap-mcu.h:17:9: error: unknown type name ‘bool’
17 | bool usb_led;
| ^~~~
So make sure, the types used in the header are available.

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.
- The usual set of cleanups, fixes and improvements all over the place

Pull irq core updates from Thomas Gleixner:
"A set of updates for the interrupt core subsystem:
- Introduce irq_chip_[startup|shutdown]_parent() to prepare for
addressing a few short comings in the PCI/MSI interrupt subsystem.
It allows to utilize the interrupt chip startup/shutdown callbacks
for initializing the interrupt chip hierarchy properly on certain
RISCV implementations and provides a mechanism to reduce the
overhead of masking and unmasking PCI/MSI interrupts during
operation when the underlying MSI provider can mask the interrupt.
The actual usage comes with the interrupt driver pull request.
- Add generic error handling for devm_request_*_irq()
This allows to remove the zoo of random error printk's all over the
usage sites.
- Add a mechanism to warn about long-running interrupt handlers
Long running interrupt handlers can introduce latencies and
tracking them down is a tedious task. The tracking has to be
enabled with a threshold on the kernel command line and utilizes a
static branch to remove the overhead when disabled.
- Update and extend the selftests which validate the CPU hotplug
interrupt migration logic
- Allow dropping the per CPU softirq lock on PREEMPT_RT kernels,
which causes contention and latencies all over the place.
The serialization requirements have been pushed down into the

otherwise the RmW operation is unprotected and events might be lost
- Fix the weak symbol reference in rseq selftests
The current weak RSEQ symbols definitions which were added to allow
static linkage are not working correctly as they effectively
re-define the glibc symbols leading to multiple versions of the

Mark them as 'extern' to convert them from weak symbol definitions

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.
