Merge tag 'vfs-6.8.netfs' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Pull netfs updates from Christian Brauner:
 "This extends the netfs helper library that network filesystems can use
  to replace their own implementations. Both afs and 9p are ported. cifs
  is ready as well but the patches are way bigger and will be routed
  separately once this is merged. That will remove lots of code as well.

  The overal goal is to get high-level I/O and knowledge of the page
  cache and ouf of the filesystem drivers. This includes knowledge about
  the existence of pages and folios

  The pull request converts afs and 9p. This removes about 800 lines of
  code from afs and 300 from 9p. For 9p it is now possible to do writes
  in larger than a page chunks. Additionally, multipage folio support
  can be turned on for 9p. Separate patches exist for cifs removing
  another 2000+ lines. I've included detailed information in the
  individual pulls I took.

  Summary:

   - Add NFS-style (and Ceph-style) locking around DIO vs buffered I/O
     calls to prevent these from happening at the same time.

   - Support for direct and unbuffered I/O.

   - Support for write-through caching in the page cache.

   - O_*SYNC and RWF_*SYNC writes use write-through rather than writing
     to the page cache and then flushing afterwards.

   - Support for write-streaming.

   - Support for write grouping.

   - Skip reads for which the server could only return zeros or EOF.

   - The fscache module is now part of the netfs library and the
     corresponding maintainer entry is updated.

   - Some helpers from the fscache subsystem are renamed to mark them as
     belonging to the netfs library.

   - Follow-up fixes for the netfs library.

   - Follow-up fixes for the 9p conversion"

ed8d84530a This cycle, I2C removes the currently unused CLASS_DDC support
(controllers set the flag, but there is no client to use it). Also,
 CLASS_SPD support gets simplified to prepare removal in the future.
 Class based instantiation is not recommended these days anyhow.
 Furthermore, I2C core now creates a debugfs directory per I2C adapter.
 Current bus driver users were converted to use it. Then, there are also
 quite some driver updates. Standing out are patches for the wmt-driver
 which is refactored to support more variants. This is the rebased pull
 request where a large series for the designware driver was dropped.

Merge tag 'cxl-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull CXL (Compute Express Link) updates from Dan Williams:
 "The bulk of this update is support for enumerating the performance
  capabilities of CXL memory targets and connecting that to a platform
  CXL memory QoS class. Some follow-on work remains to hook up this data
  into core-mm policy, but that is saved for v6.9.

  The next significant update is unifying how CXL event records (things
  like background scrub errors) are processed between so called
  "firmware first" and native error record retrieval. The CXL driver
  handler that processes the record retrieved from the device mailbox is
  now the handler for that same record format coming from an EFI/ACPI
  notification source.

  This also contains miscellaneous feature updates, like Get Timestamp,
  and other fixups.

  Summary:

   - Add support for parsing the Coherent Device Attribute Table (CDAT)

   - Add support for calculating a platform CXL QoS class from CDAT data

   - Unify the tracing of EFI CXL Events with native CXL Events.

   - Add Get Timestamp support

   - Miscellaneous cleanups and fixups"

244aefb1c6 VFIO updates for v6.8-rc1
- Add debugfs support, initially used for reporting device migration
    state. (Longfang Liu)
 
  - Fixes and support for migration dirty tracking across multiple IOVA
    regions in the pds-vfio-pci driver. (Brett Creeley)
 
  - Improved IOMMU allocation accounting visibility. (Pasha Tatashin)
 
  - Virtio infrastructure and a new virtio-vfio-pci variant driver, which
    provides emulation of a legacy virtio interfaces on modern virtio
    hardware for virtio-net VF devices where the PF driver exposes
    support for legacy admin queues, ie. an emulated IO BAR on an SR-IOV
    VF to provide driver ABI compatibility to legacy devices.
    (Yishai Hadas & Feng Liu)
 
  - Migration fixes for the hisi-acc-vfio-pci variant driver.
    (Shameer Kolothum)
 
  - Kconfig dependency fix for new virtio-vfio-pci variant driver.

ed6c23b175 This is the main pin control pull request for the v6.8 kernel series.
Core changes:
 
 - A new PINCTRL_GROUP_DESC() infrastructure macro is added and
   used in different drivers, generic group description struct
   group_desc is now used all over the place.
 
 New drivers:
 
 - New driver for the Texas Instruments TPS6494 Power Management IC.
 
 - New driver for the Lantic PEF2256 framer pin multiplexer.
   This IC has some pins that can be reconfigured in different
   ways. The actual driver comes on an immutable branch with the
   net WAN parts, the IC is some latest-and-greatest serial line
   funnel for e.g. wireless access points.
 
 - New subdriver for the Samsung Exynos Auto V920 pin controller,
   used for automotive applications.
 
 - New subdriver for the Samsung "GS101" SoC pin controller, this
   is the Google "Tensor" SoC used in the Google Pixel 6.
 
 - New subdriver for the Intel Meteor Point SoC pin controller.
 
 - New subdriver for the Qualcomm SM8650 top level (TLMM) and LPASS pin
   controllers.
 
 - New subdriver for the Qualcomm X1E80100 top level (TLMM) pin
   controller.
 
 - New subdriver for the Qualcomm SM4450 top level (TLMM) pin
   controller.
 
 - The "single" pin controller now supports the Texas Instruments
   J7200 SoC.
 
 Improvements:
 
 - Intel has created a new (Intel-)generic pin controller driver that
   is now used by all contemporary Intel platforms.
 
 - Intel is now also making use of some cleanup helpers.
 
 - Enble 910 Ohm bias in the Intel Tangier driver.
 
 - The Samsung driver now suppors irq_set_affinity() in it's IRQ chip
   giving support for non wake up external gpio interrupts.

Pull pin control updates from Linus Walleij:
 "For this kernel cycle I managed an immutable branch for the PEF2256
  WAN framer that has some pin control portions. It already landed in
  your tree through the net pull request but here it is mentioned again.

  The most interesting is perhaps the Samsung Exynos subdrivers for the
  Tensor SoC used in Google Pixel 6 and the ExynosAuto subdriver for
  automotive. Along with the earlier merged Tesla FSD subdriver it shows
  some of the versatile uses of the Samsung Exynos silicon. It is also
  used in the latest version of Axis Communications ARTPEC chips so it
  is a very widely deployed SoC family.

  We also have the Intel Meteor Lake SoC which I think is for laptops.
  It's a pretty interesting chip with Xe graphics and integrated PCH.

  Core changes:

   - A new PINCTRL_GROUP_DESC() infrastructure macro is added and used
     in different drivers, generic group description struct group_desc
     is now used all over the place.

  New drivers:

   - New driver for the Texas Instruments TPS6494 Power Management IC.

   - New driver for the Lantic PEF2256 framer pin multiplexer. This IC
     has some pins that can be reconfigured in different ways. The
     actual driver comes on an immutable branch with the net WAN parts,
     the IC is some latest-and-greatest serial line funnel for e.g.
     wireless access points.

   - New subdriver for the Samsung Exynos Auto V920 pin controller, used
     for automotive applications.

   - New subdriver for the Samsung "GS101" SoC pin controller, this is
     the Google "Tensor" SoC used in the Google Pixel 6.

   - New subdriver for the Intel Meteor Point SoC pin controller.

   - New subdriver for the Qualcomm SM8650 top level (TLMM) and LPASS
     pin controllers.

   - New subdriver for the Qualcomm X1E80100 top level (TLMM) pin
     controller.

   - New subdriver for the Qualcomm SM4450 top level (TLMM) pin
     controller.

   - The "single" pin controller now supports the Texas Instruments
     J7200 SoC.

  Improvements:

   - Intel has created a new (Intel-)generic pin controller driver that
     is now used by all contemporary Intel platforms.

   - Intel is now also making use of some cleanup helpers.

   - Enble 910 Ohm bias in the Intel Tangier driver.

   - The Samsung driver now suppors irq_set_affinity() in it's IRQ chip
     giving support for non wake up external gpio interrupts"

42bff4d0f9 pwm: Changes for v6.8-rc1
This contains a bunch of cleanups and simplifications across the board,
 as well as a number of small fixes.
 
 Perhaps the most notable change here is the addition of an API that
 allows PWMs to be used in atomic contexts, which is useful when time-
 critical operations are involved, such as using a PWM to generate IR
 signals.
 
 Finally, I have decided to step down as PWM subsystem maintainer. Due to
 other responsibilities I have lately not been able to find the time that
 the subsystem deserves and Uwe, who has been helping out a lot for the
 past few years and has many things planned for the future, has kindly
 volunteered to take over. I have no doubt that he will be a suitable
 replacement.

7912a6391f sound updates for 6.8-rc1
It was a clam development cycle.  There were an ALSA core extension
 for subformat PCM bits and a few ASoC core changes to support N:M
 mappings, while the most of remaining changes are driver-specific.
 
 Core:
 - API extensions for properly limiting PCM format bits via subformat
 - Enhanced support for N:M CPU:CODEC mappings in the core and in
   audio-graph-card2
 
 ASoC:
 - Lots of SOF updates: fallback support to older IPC versions,
   notification on control changes with IPC4.
   Also supports for ACPI parse for the ES83xx driver that reduces
   quirks.
 - Device tree support for describing parts of the card which can be
   active over suspend (for very low power playback or wake word use
   cases)
 - Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
   SM8250, SM8550, SM8650 and X1E80100
 - Drop of Freescale MPC8610 code that is no longer supported
 
 HD-audio:
 - More CS35L41 codec extensions for Dell, HP and Lenovo models
 - TAS2781 codec extensions for Lenovo and co
 - New PCM subformat supports
 
 Others:
 - More enhancement for Scarlett2 USB mixer support
 - Various kselftest fixes

Pull drm updates from Dave Airlie:
 "This contains two major new drivers:

   - imagination is a first driver for Imagination Technologies devices,
     it only covers very specific devices, but there is hope to grow it

   - xe is a reboot of the i915 GPU (shares display) side using a more
     upstream focused development model, and trying to maximise code
     sharing. It's not enabled for any hw by default, and will hopefully
     get switched on for Intel's Lunarlake.

  This also drops a bunch of the old UMS ioctls. It's been dead long
  enough.

  amdgpu has a bunch of new color management code that is being used in
  the Steam Deck.

  amdgpu also has a new ACPI WBRF interaction to help avoid radio
  interference.

7afc0e7f68 MAINTAINERS: pwm: Thierry steps down, Uwe takes over
It's not easy to let go responsibility for a subsystem that one cared
for for a long time, but Thierry realized that his heart isn't in the
pwm framework any more.

Thierry cared for the pwm subsystem (commit 200efedd87 ("pwm: Take
over maintainership of the PWM subsystem")) as a maintainer during
nearly 12 years. A big thanks for the time, effort and dedication spend
during that time.

Uwe takes over maintenance.

689237ab37 fbdev/intelfb: Remove driver
From looking at the PCI IDs, every device supported by intelfb is
also supported by i915. Anyone still using intelfb should please
move on to i915, which does everything intelfb does but better.

Removing intelfb is motivated by the driver's excessive use of the
global screen_info state. The state belongs to architecture and
firmware code; device drivers should not attempt to access it. But
fixing intelfb would require a significant change in the driver's
probing logic. As intelfb has been obsolete for nearly 2 decades,
it is probably not worth the effort. Let's just remove it. Also
remove the related documentation.

dee56ccb46 fbdev: amba-clcd: Delete the old CLCD driver
We have managed to ascertain that all users of the old FBDEV
code that are out of tree are now gone.

The new DRM driver can be found in drivers/gpu/drm/pl111/.

The remaining out of tree user was the ARM FVP emulation
platform, running Android. Thanks to changes in Android
versions 13 and 14, Android can now use the DRM driver when
being emulated under FVP. Some final patches are being put
in place to make it fully featured.

This is essentially a revert of the partial revert in

fb249b275c ARM: SoC code changes for 6.8
There are two notable changes this time:
 
 - Andrew Davis adds a arch/arm/Kconfig.platforms file to simplify
   the platforms that have no code except their Kconfig file
 
 - Linux Walleij removes support for the ARM11MPCore CPU in
   the versatile/realview platform. Since this is the last
   remaining one after removing ox820, some core code can go
   as well.
 
 The other changes are minor cleanups and bugfixes.

A new drivers/cache/ subsystem is added to contain drivers for abstracting
 cache flush methods on riscv and potentially others, as this is needed for
 handling non-coherent DMA but several SoCs require nonstandard hardware
 methods for it.
 
 op-tee gains support for asynchronous notification with FF-A, as well
 as support for a system thread for executing in secure world.
 
 The tee, reset, bus, memory and scmi subsystems have a couple of minor
 updates.
 
 Platform specific soc driver changes include:
 
  - Samsung Exynos gains driver support for Google GS101 (Tensor G1)
    across multiple subsystems
 
  - Qualcomm Snapdragon gains support for SM8650 and X1E along with
    added features for some other SoCs
 
  - Mediatek adds support for "Smart Voltage Scaling" on MT8186 and MT8195,
    and driver support for MT8188 along with some code refactoring.
 
  - Microchip Polarfire FPGA support for "Auto Update" of the FPGA bitstream

c4101e5597 SoC: DT changes for 6.8
There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both
 the Rockchips rv1109 and Sopgho CV1812H are just minor variations of
 already supported chips.
 
 The other six new SoCs are all part of existing arm64 families, but
 are somewhat more interesting:
 
  - Samsung ExynosAutov920 is an automotive chip, and the first one
    we support based on the Cortex-A78AE core with lockstep mode.
 
  - Google gs101 (Tensor G1) is the chip used in a number of Pixel phones,
    and is grouped with Samsung Exynos here since it is based on the same
    SoC design, sharing most of its IP blocks with that series.
 
  - MediaTek MT8188 is a new chip used for mid-range tablets and Chromebooks,
    using two Cortex-A78 cores where the older MT8195 had four of them.
 
  - Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
    phone SoC and the first supported chip based on Cortex-X4, Cortex-A720
    and Cortex-A520.
 
  - Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest
    Laptop chip using the custom Oryon cores.
 
  - Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
    Cortex-A76 and Cortex-A55
 
 In terms of boards, we have
 
  - Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
    G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.
 
  - Multiple Rockchips mobile gaming systems (Anbernic RG351V,
    Powkiddy RK2023, Powkiddy X55) along with the Sonoff iHost Smart
    Home Hub and a few Rockchips SBCs
 
  - Some ComXpress boards based on Marvell CN913x, which is the
    follow-up to Armada 7xxx/8xxx.
 
  - Six new industrial/embedded boards based on NXP i.MX8 and i.MX9
 
  - Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer.
 
  - Toradex Verdin AM62 Mallow carrier for TI AM62
 
  - Huashan Pi board based on the SophGo CV1812H RISC-V chip
 
  - Two boards based on Allwinner H616/H618
 
  - A number of reference boards for various added SoCs from Qualcomm,
    Mediatek, Google, Samsung, NXP and Spreadtrum
 
 As usual, there are cleanups and warning fixes across all platforms as
 well as added features for several of them.

Merge tag 'soc-dt-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC DT updates from Arnd Bergmann:
 "There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both
  the Rockchips rv1109 and Sopgho CV1812H are just minor variations of
  already supported chips.

  The other six new SoCs are all part of existing arm64 families, but
  are somewhat more interesting:

   - Samsung ExynosAutov920 is an automotive chip, and the first one we
     support based on the Cortex-A78AE core with lockstep mode.

   - Google gs101 (Tensor G1) is the chip used in a number of Pixel
     phones, and is grouped with Samsung Exynos here since it is based
     on the same SoC design, sharing most of its IP blocks with that
     series.

   - MediaTek MT8188 is a new chip used for mid-range tablets and
     Chromebooks, using two Cortex-A78 cores where the older MT8195 had
     four of them.

   - Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
     phone SoC and the first supported chip based on Cortex-X4,
     Cortex-A720 and Cortex-A520.

   - Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest Laptop
     chip using the custom Oryon cores.

   - Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
     Cortex-A76 and Cortex-A55

  In terms of boards, we have

   - Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
     G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.

   - Multiple Rockchips mobile gaming systems (Anbernic RG351V, Powkiddy
     RK2023, Powkiddy X55) along with the Sonoff iHost Smart Home Hub
     and a few Rockchips SBCs

   - Some ComXpress boards based on Marvell CN913x, which is the
     follow-up to Armada 7xxx/8xxx.

   - Six new industrial/embedded boards based on NXP i.MX8 and i.MX9

   - Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer.

   - Toradex Verdin AM62 Mallow carrier for TI AM62

   - Huashan Pi board based on the SophGo CV1812H RISC-V chip

   - Two boards based on Allwinner H616/H618

   - A number of reference boards for various added SoCs from Qualcomm,
     Mediatek, Google, Samsung, NXP and Spreadtrum

  As usual, there are cleanups and warning fixes across all platforms as
  well as added features for several of them"

Linus Torvalds
3e7aeb78ab Networking changes for 6.8.
Core & protocols
 ----------------
 
  - Analyze and reorganize core networking structs (socks, netdev,
    netns, mibs) to optimize cacheline consumption and set up
    build time warnings to safeguard against future header changes.
    This improves TCP performances with many concurrent connections
    up to 40%.
 
  - Add page-pool netlink-based introspection, exposing the
    memory usage and recycling stats. This helps indentify
    bad PP users and possible leaks.
 
  - Refine TCP/DCCP source port selection to no longer favor even
    source port at connect() time when IP_LOCAL_PORT_RANGE is set.
    This lowers the time taken by connect() for hosts having
    many active connections to the same destination.
 
  - Refactor the TCP bind conflict code, shrinking related socket
    structs.
 
  - Refactor TCP SYN-Cookie handling, as a preparation step to
    allow arbitrary SYN-Cookie processing via eBPF.
 
  - Tune optmem_max for 0-copy usage, increasing the default value
    to 128KB and namespecifying it.
 
  - Allow coalescing for cloned skbs coming from page pools, improving
    RX performances with some common configurations.
 
  - Reduce extension header parsing overhead at GRO time.
 
  - Add bridge MDB bulk deletion support, allowing user-space to
    request the deletion of matching entries.
 
  - Reorder nftables struct members, to keep data accessed by the
    datapath first.
 
  - Introduce TC block ports tracking and use. This allows supporting
    multicast-like behavior at the TC layer.
 
  - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
    classifiers (RSVP and tcindex).
 
  - More data-race annotations.
 
  - Extend the diag interface to dump TCP bound-only sockets.
 
  - Conditional notification of events for TC qdisc class and actions.
 
  - Support for WPAN dynamic associations with nearby devices, to form
    a sub-network using a specific PAN ID.
 
  - Implement SMCv2.1 virtual ISM device support.
 
  - Add support for Batman-avd mulicast packet type.
 
 BPF
 ---
 
  - Tons of verifier improvements:
    - BPF register bounds logic and range support along with a large
      test suite
    - log improvements
    - complete precision tracking support for register spills
    - track aligned STACK_ZERO cases as imprecise spilled registers. It
      improves the verifier "instructions processed" metric from single
      digit to 50-60% for some programs
    - support for user's global BPF subprogram arguments with few
      commonly requested annotations for a better developer experience
    - support tracking of BPF_JNE which helps cases when the compiler
      transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
      like
    - several fixes
 
  - Add initial TX metadata implementation for AF_XDP with support in
    mlx5 and stmmac drivers. Two types of offloads are supported right
    now, that is, TX timestamp and TX checksum offload.
 
  - Fix kCFI bugs in BPF all forms of indirect calls from BPF into
    kernel and from kernel into BPF work with CFI enabled. This allows
    BPF to work with CONFIG_FINEIBT=y.
 
  - Change BPF verifier logic to validate global subprograms lazily
    instead of unconditionally before the main program, so they can be
    guarded using BPF CO-RE techniques.
 
  - Support uid/gid options when mounting bpffs.
 
  - Add a new kfunc which acquires the associated cgroup of a task
    within a specific cgroup v1 hierarchy where the latter is identified
    by its id.
 
  - Extend verifier to allow bpf_refcount_acquire() of a map value field
    obtained via direct load which is a use-case needed in sched_ext.
 
  - Add BPF link_info support for uprobe multi link along with bpftool
    integration for the latter.
 
  - Support for VLAN tag in XDP hints.
 
  - Remove deprecated bpfilter kernel leftovers given the project
    is developed in user-space (https://github.com/facebook/bpfilter).
 
 Misc
 ----
 
  - Support for parellel TC self-tests execution.
 
  - Increase MPTCP self-tests coverage.
 
  - Updated the bridge documentation, including several so-far
    undocumented features.
 
  - Convert all the net self-tests to run in unique netns, to
    avoid random failures due to conflict and allow concurrent
    runs.
 
  - Add TCP-AO self-tests.
 
  - Add kunit tests for both cfg80211 and mac80211.
 
  - Autogenerate Netlink families documentation from YAML spec.
 
  - Add yml-gen support for fixed headers and recursive nests, the
    tool can now generate user-space code for all genetlink families
    for which we have specs.
 
  - A bunch of additional module descriptions fixes.
 
  - Catch incorrect freeing of pages belonging to a page pool.
 
 Driver API
 ----------
 
  - Rust abstractions for network PHY drivers; do not cover yet the
    full C API, but already allow implementing functional PHY drivers
    in rust.
 
  - Introduce queue and NAPI support in the netdev Netlink interface,
    allowing complete access to the device <> NAPIs <> queues
    relationship.
 
  - Introduce notifications filtering for devlink to allow control
    application scale to thousands of instances.
 
  - Improve PHY validation, requesting rate matching information for
    each ethtool link mode supported by both the PHY and host.
 
  - Add support for ethtool symmetric-xor RSS hash.
 
  - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
    platform.
 
  - Expose pin fractional frequency offset value over new DPLL generic
    netlink attribute.
 
  - Convert older drivers to platform remove callback returning void.
 
  - Add support for PHY package MMD read/write.

a05aea98d4 sysctl-6.8-rc1
To help make the move of sysctls out of kernel/sysctl.c not incur a size
 penalty sysctl has been changed to allow us to not require the sentinel, the
 final empty element on the sysctl array. Joel Granados has been doing all this
 work. On the v6.6 kernel we got the major infrastructure changes required to
 support this. For v6.7 we had all arch/ and drivers/ modified to remove
 the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only.
 The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches
 are still being reviewed. After that we then can expect also the removal of the
 no longer needed check for procname == NULL.
 
 Let us recap the purpose of this work:
 
   - this helps reduce the overall build time size of the kernel and run time
     memory consumed by the kernel by about ~64 bytes per array
   - the extra 64-byte penalty is no longer inncurred now when we move sysctls
     out from kernel/sysctl.c to their own files
 
 Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further
 work by Thomas Weißschuh with the constificatin of the struct ctl_table.
 
 Due to Joel Granados's work, and to help bring in new blood, I have suggested
 for him to become a maintainer and he's accepted. So for v6.9-rc1 I look forward
 to seeing him sent you a pull request for further sysctl changes. This also
 removes Iurii Zaikin as a maintainer as he has moved on to other projects and
 has had no time to help at all.
