95920c2ed0 page_pool: Fix PP_MAGIC_MASK to avoid crashing on some 32-bit arches 
Helge reported that the introduction of PP_MAGIC_MASK let to crashes on
boot on his 32-bit parisc machine. The cause of this is the mask is set
too wide, so the page_pool_page_is_pp() incurs false positives which
crashes the machine.

Just disabling the check in page_pool_is_pp() will lead to the page_pool
code itself malfunctioning; so instead of doing this, this patch changes
the define for PP_DMA_INDEX_BITS to avoid mistaking arbitrary kernel
pointers for page_pool-tagged pages.

The fix relies on the kernel pointers that alias with the pp_magic field
always being above PAGE_OFFSET. With this assumption, we can use the
lowest bit of the value of PAGE_OFFSET as the upper bound of the
PP_DMA_INDEX_MASK, which should avoid the false positives.

Because we cannot rely on PAGE_OFFSET always being a compile-time
constant, nor on it always being >0, we fall back to disabling the
dma_index storage when there are not enough bits available. This leaves
us in the situation we were in before the patch in the Fixes tag, but
only on a subset of architecture configurations. This seems to be the
best we can do until the transition to page types in complete for
page_pool pages.

v2:
- Make sure there's at least 8 bits available and that the PAGE_OFFSET
  bit calculation doesn't wrap

07fdad3a93 Networking changes for 6.18. 
Core & protocols
 ----------------
 
  - Improve drop account scalability on NUMA hosts for RAW and UDP sockets
    and the backlog, almost doubling the Pps capacity under DoS.
 
  - Optimize the UDP RX performance under stress, reducing contention,
    revisiting the binary layout of the involved data structs and
    implementing NUMA-aware locking. This improves UDP RX performance by
    an additional 50%, even more under extreme conditions.
 
  - Add support for PSP encryption of TCP connections; this mechanism has
    some similarities with IPsec and TLS, but offers superior HW offloads
    capabilities.
 
  - Ongoing work to support Accurate ECN for TCP. AccECN allows more than
    one congestion notification signal per RTT and is a building block for
    Low Latency, Low Loss, and Scalable Throughput (L4S).
 
  - Reorganize the TCP socket binary layout for data locality, reducing
    the number of touched cachelines in the fastpath.
 
  - Refactor skb deferral free to better scale on large multi-NUMA hosts,
    this improves TCP and UDP RX performances significantly on such HW.
 
  - Increase the default socket memory buffer limits from 256K to 4M to
    better fit modern link speeds.
 
  - Improve handling of setups with a large number of nexthop, making dump
    operating scaling linearly and avoiding unneeded synchronize_rcu() on
    delete.
 
  - Improve bridge handling of VLAN FDB, storing a single entry per bridge
    instead of one entry per port; this makes the dump order of magnitude
    faster on large switches.
 
  - Restore IP ID correctly for encapsulated packets at GSO segmentation
    time, allowing GRO to merge packets in more scenarios.
 
  - Improve netfilter matching performance on large sets.
 
  - Improve MPTCP receive path performance by leveraging recently
    introduced core infrastructure (skb deferral free) and adopting recent
    TCP autotuning changes.
 
  - Allow bridges to redirect to a backup port when the bridge port is
    administratively down.
 
  - Introduce MPTCP 'laminar' endpoint that con be used only once per
    connection and simplify common MPTCP setups.
 
  - Add RCU safety to dst->dev, closing a lot of possible races.
 
  - A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing
    code duplication.
 
  - Supports pulling data from an skb frag into the linear area of an XDP
    buffer.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Generate netlink documentation from YAML using an integrated
    YAML parser.
 
 Driver API
 ----------
 
  - Support using IPv6 Flow Label in Rx hash computation and RSS queue
    selection.
 
  - Introduce API for fetching the DMA device for a given queue, allowing
    TCP zerocopy RX on more H/W setups.
 
  - Make XDP helpers compatible with unreadable memory, allowing more
    easily building DevMem-enabled drivers with a unified XDP/skbs
    datapath.
 
  - Add a new dedicated ethtool callback enabling drivers to provide the
    number of RX rings directly, improving efficiency and clarity in RX
    ring queries and RSS configuration.
 
  - Introduce a burst period for the health reporter, allowing better
    handling of multiple errors due to the same root cause.
 
  - Support for DPLL phase offset exponential moving average, controlling
    the average smoothing factor.
 
 Device drivers
 --------------
 
  - Add a new Huawei driver for 3rd gen NIC (hinic3).
 
  - Add a new SpacemiT driver for K1 ethernet MAC.
 
  - Add a generic abstraction for shared memory communication devices
    (dibps)
 
  - Ethernet high-speed NICs:
    - nVidia/Mellanox:
      - Use multiple per-queue doorbell, to avoid MMIO contention issues

        SR-IOV VFs to sibling PFs
      - support RSS for IPSec offload
      - support exposing raw cycle counters in PTP and mlx5

Linus Torvalds
05a54fa773 sound updates for 6.18-rc1 
It's been relatively calm in this cycle from the feature POV, but
 there were lots of cleanup works in the wide-range of code for
 converting with the auto-cleanup macros like guard().
 The mostly user-visible changes are the support of a couple of new
 compress-offload API extensions, and the support of new ASoC codec /
 platform drivers as well as USB-audio quirks.
 
 Here we go with some highlights:
 
 Core:
  - Compress-offload API extension for 64bit timestamp support
  - Compress-offload API extension for OPUS codec support
  - Workaround for PCM locking issue with PREEMPT_RT and softirq
  - KCSAN warning fix for ALSA sequencer core
 
 ASoC:
  - Continued cleanup works for ASoC core APIs
  - Lots of cleanups and conversions of DT bindings
  - Substantial maintainance work on the Intel AVS drivers
  - Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
    FourSemi FS2104/5S, Texas Instruments PCM1754 and TAS2783A
  - Remove support for TI WL1273 for old Nokia systems
 
 USB-audio:
  - Support for Tascam US-144mkII, Presonus S1824c support
  - More flexible quirk option handling
  - Fix for USB MIDI timer bug triggered by fuzzer
 
 Others:
  - A large series of cleanups with guard() & co macros over (non-ASoC)
    sound drivers (PCI, ISA, HD-audio, USB-audio, drivers, etc)
  - TAS5825 HD-audio side-codec support

Pull sound updates from Takashi Iwai:
 "It's been relatively calm in this cycle from the feature POV, but
  there were lots of cleanup works in the wide-range of code for
  converting with the auto-cleanup macros like guard().

  The mostly user-visible changes are the support of a couple of new
  compress-offload API extensions, and the support of new ASoC codec /
  platform drivers as well as USB-audio quirks.

  Here we go with some highlights:

  Core:
   - Compress-offload API extension for 64bit timestamp support
   - Compress-offload API extension for OPUS codec support
   - Workaround for PCM locking issue with PREEMPT_RT and softirq
   - KCSAN warning fix for ALSA sequencer core

  ASoC:
   - Continued cleanup works for ASoC core APIs
   - Lots of cleanups and conversions of DT bindings
   - Substantial maintainance work on the Intel AVS drivers
   - Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
     FourSemi FS2104/5S, Texas Instruments PCM1754 and TAS2783A
   - Remove support for TI WL1273 for old Nokia systems

  USB-audio:
   - Support for Tascam US-144mkII, Presonus S1824c support
   - More flexible quirk option handling
   - Fix for USB MIDI timer bug triggered by fuzzer

  Others:
   - A large series of cleanups with guard() & co macros over (non-ASoC)
     sound drivers (PCI, ISA, HD-audio, USB-audio, drivers, etc)
   - TAS5825 HD-audio side-codec support"

 - 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

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.

30bbcb4470 linux_kselftest-kunit-6.18-rc1 
- A seven patch series adds a new parameterized test features
   KUnit parameterized tests currently support two primary methods for
   getting parameters:
     1.  Defining custom logic within a generate_params() function.
     2.  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.
 
 - Fixes issues in kunit build artifacts cleanup,
 - Fixes parsing skipped test problem in kselftest framework,
 - Enables PCI on UML without triggering WARN()
 - a few other fixes and adds support for new configs such as MIPS

   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()

 - a few other fixes and adds support for new configs such as MIPS

d2b2fea350 asm-generic: updates for 6.18 
Two small patches for the asm-generic header files: Varad Gautam improves
 the MMIO tracing to be faster when the tracepoints are built into the
 kernel but disabled, while Qi Xi updates the DO_ONCE logic so that
 clearing the WARN_ONCE() flags does not change the other DO_ONCE users.

0f048c878e soc: dt changes for 6.18 
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 power management updates from Rafael Wysocki:
 "The majority of these are cpufreq changes, which has been a recurring
  pattern for a few recent cycles.

  Those changes include new hardware support (AN7583 SoC support in the
  airoha cpufreq driver, ipq5424 support in the qcom-nvmem cpufreq
  driver, MT8196 support in the mediatek cpufreq driver, AM62D2 support
  in the ti cpufreq driver), DT bindings and Rust code updates, cleanups
  of the core and governors, and multiple driver fixes and cleanups.

  Beyond that, there are hibernation fixes (some remaining 6.16 cycle
  fallout and an issue related to hybrid suspend in the amdgpu driver),
  cleanups of the PM core code, runtime PM documentation update, cpuidle
  and power capping cleanups, and tooling updates.

  Specifics:

   - Rearrange variable declarations involving __free() in the cpufreq
     core and intel_pstate driver to follow common coding style (Rafael
     Wysocki)

   - Fix object lifecycle issue in update_qos_request(), rearrange freq
     QoS updates using __free(), and adjust frequency percentage
     computations in the intel_pstate driver (Rafael Wysocki)

   - Update intel_pstate to allow it to enable HWP without EPP if the
     new DEC (Dynamic Efficiency Control) HW feature is enabled (Rafael

     core to simplify the initial policy path (Zihuan Zhang)

   - Clean up the cpufreq core in multiple places (Zihuan Zhang)

   - Use int type to store negative error codes in the cpufreq core and
     update the speedstep-lib to use int for error codes (Qianfeng Rong)

   - Update the efficient idle check for Intel extended Families in the
     ondemand cpufreq governor (Sohil Mehta)

   - Replace sscanf() with kstrtouint() in the conservative cpufreq
     governor (Kaushlendra Kumar)

     ti,am62d2 SoC in dt-platdev (Paresh Bhagat)

   - Support more speed grades on AM62Px SoC in the ti cpufreq driver,
     allow all silicon revisions to support OPPs in it, and fix
     supported hardware for 1GHz OPP (Judith Mendez)

   - Add QCS615 compatible to DT bindings for cpufreq-qcom-hw (Taniya
     Das)

   - Minor assorted updates of the scmi, longhaul, CPPC, and armada-37xx
     cpufreq drivers (Akhilesh Patil, BowenYu, Dennis Beier, and Florian
     Fainelli)

5fb0249319 Pin control changes for the v6.18 kernel cycle: 
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.

     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"

524c4a5daf Bug fixes and enhancements for IPMI 
This request 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.  There is a
 conflict in the MAINTAINERS file and the MFD tree changes must be
 there before this is applied.
 
 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.

f07c3695bf firewire updates for v6.18 
This update includes the following changes:
 
 - Removal of the deprecated debug parameter from firewire-ohci module
 - Replacement of the module-local workqueue in 1394 OHCI PCI driver with
   a companion IRQ thread
 - Refactoring of bus management code
 - Additional minor code cleanup
 
 The existing tracepoints serve as an alternative to the removed debug
 parameter. The use of IRQ thread is experimental, as it handles 1394 OHCI
 SelfIDComplete event only. It may be replaced in the future releases with
 another approach; e.g. by providing workqueue from core functionality

b4918003cf MFD for v6.18 
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.
 - Introduce support for the TI TPS6594 PMIC's power button, including the input driver, MFD
   cell registration, and a system power-off handler.
 - Add comprehensive support for the TI BQ257xx series of charger ICs, including the core MFD
   driver and a power supply driver for the charger functionality.
 
 Improvements & Fixes
 - Check the return value of devm_gpiochip_add_data() in the VEXPRESS sysreg driver to prevent
   potential silent failures.
 
 Cleanups & Refactoring
 - Add a MAINTAINERS entry for the new Loongson Security Engine drivers.
 - Convert the VEXPRESS sysreg driver to use the modern generic GPIO chip API.
 
 Removals
 - Remove the deprecated and unused mc13xxx_irq_ack() function from the MC13xxx RTC, input and
   touchscreen drivers.
 
 Device Tree Bindings Updates
 - Add device tree bindings for the TI BQ25703A charger.

ea1c6c5925 spi: Updates for v6.18 
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 VirtIO
    controllers.

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.

c050daf69f pwm: Changes for v6.18-rc1 
The core highlights for this cycle are:
 
  - The pca9586 driver was converted to the waveform API.
  - Waveform drivers automatically provide a gpio chip to make PWMs
    usable as GPIOs. (The pca9586 driver did that in a driver specific
    implementation before.)
 
 Otherwise it's the usual mix of fixes and device tree and driver changes
 to support new hardware variants.

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;

03a53e09cd Updates for interrupt chip drivers: 
- Use the startup/shutdown callbacks for the PCI/MSI per device interrupt
     domains.
 
     This allows 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.

     initializing the interrupt chip hierarchy properly on certain RISCV

     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.

1d17e808cf Two fixes for RSEQ: 
1) Protect the event mask modification against the membarrier() IPI as
      otherwise the RmW operation is unprotected and events might be lost.
 
   2) 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 the effectively re-define
      the glibc symbols leading to multiple versions of the symbols when
      compiled with -fno-common. Mark them as 'extern' to convert them from
      weak symbol definitions to weak symbol references. That works with

Pull rseq updates from Thomas Gleixner:
 "Two fixes for RSEQ:

   - Protect the event mask modification against the membarrier() IPI as
     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
     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"

7601d18be0 A set of changes to consolidate the generic TIF bits accross architectures 
All architectures define the same set of generic TIF bits. This makes it
 pointlessly hard to add a new generic TIF bit or to change an existing one.
 
 Provide a generic variant and convert the architectures which utilize the
 generic entry code over to use it. The TIF space is divided into 16 generic
 bits and 16 architecture specific bits, which turned out to provide enough
 space on both sides.
