 "Mostly just come fixes and cleanups, but one feature as well. In
  detail:

   - Harden the check for handling IOPOLL based on return (Pavel)

   - Various minor optimizations (Pavel)

   - Drop remnants of SCM_RIGHTS fd passing support, now that it's no
     longer supported since 6.7 (me)

   - Fix for a case where bytes_done wasn't initialized properly on a
     failure condition for read/write requests (me)

   - Move the register related code to a separate file (me)

   - Add support for returning the provided ring buffer head (me)

   - Add support for adding a direct descriptor to the normal file table
     (me, Christian Brauner)

   - Fix for ensuring pending task_work for a ring with DEFER_TASKRUN is
     run even if we timeout waiting (me)"

b6964fe239 Rust changes for v6.8
Another routine one in terms of features. In terms of lines, this time
 the 'alloc' version upgrade is less prominent, given that it was fairly
 small (and we did not have two upgrades).
 
 Toolchain and infrastructure:
 
  - Upgrade to Rust 1.74.1.
 
    The patch release includes a fix for an ICE that the Apple AGX GPU
    driver was hitting.
 
  - Support 'srctree'-relative links in Rust code documentation.
 
  - Automate part of the manual constants handling (i.e. the ones not
    recognised by 'bindgen').
 
  - Suppress searching builtin sysroot to avoid confusion with installed
    sysroots, needed for the to-be-merged arm64 support which uses
    a builtin target.
 
  - Ignore '__preserve_most' functions for 'bindgen'.
 
  - Reduce header inclusion bloat in exports.
 
 'kernel' crate:
 
  - Implement 'Debug' for 'CString'.
 
  - Make 'CondVar::wait()' an uninterruptible wait.
 
 'macros' crate:
 
  - Update 'paste!' to accept string literals.
 
  - Improve '#[vtable]' documentation.
 
 Documentation:
 
  - Add testing section (KUnit and 'rusttest' target).
 
  - Remove 'CC=clang' mentions.
 
  - Clarify that 'rustup override' applies to build directory.

3f302388d4 io_uring/rsrc: improve code generation for fixed file assignment
For the normal read/write path, we have already locked the ring
submission side when assigning the file. This causes branch
mispredictions when we then check and try and lock again in
io_req_set_rsrc_node(). As this is a very hot path, this matters.

Add a basic helper that already assumes we already have it locked,
and use that in io_file_get_fixed().

As usual, the arm32 and arm64 defconfig files get changed to account
 for added device drivers that can now be used.
 
 The files are also refreshed to reflect the more recent Kconfig changes
 that are going into v6.8.

d898c2e555 drm/xe/guc: Return CTB response length
Not all CTB responses from the GuC are fixed size and we need to
pass response length to the caller, if there was a response_buffer.
Easiest solution is to return it as positive value from all
xe_guc_ct_send_recv() functions.  The CTB response length is always
between 1 and 254 (ie. GUC_HXG_MSG_MIN_LEN and GUC_CTB_MAX_DWORDS
- GUC_HXG_MSG_MIN_LEN).

47f2bd2ff3 iommufd/selftest: Check the bus type during probe
This relied on the probe function only being invoked by the bus type mock
was registered on. The removal of the bus ops broke this assumption and
the probe could be called on non-mock bus types like PCI.

Check the bus type directly in probe.

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.

f6597d1706 SoC: driver updates for 6.8
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
 
  - Apple M1 mailbox driver is rewritten into a SoC driver
 
  - minor updates on amlogic, mvebu, ti, zynq, imx, renesas and hisilicon

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.

  - 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.

60a031b649 media: i2c: thp7312: select CONFIG_FW_LOADER
The recently added driver uses the firmware loader mechanism but causes
a link failure when that is in a loadable module while thp7312 itself
is built-in:

arm-linux-gnueabi-ld: drivers/media/i2c/thp7312.o: in function `thp7312_probe':
thp7312.c:(.text+0x4164): undefined reference to `firmware_upload_register'

Select the required Kconfig symbol. Note that the driver specifically
needs the firmware upload interface that is controlled by CONFIG_FW_UPLOAD,
but there is no link failure when that is disabled because the interfaces
are stubbed out here.

80df7d6af7 s390/pci: fix max size calculation in zpci_memcpy_toio()
The zpci_get_max_write_size() helper is used to determine the maximum
size a PCI store or load can use at a given __iomem address.

For the PCI block store the following restrictions apply:

1. The dst + len must not cross a 4K boundary in the (pseudo-)MMIO space
2. len must not exceed ZPCI_MAX_WRITE_SIZE
3. len must be a multiple of 8 bytes
4. The src address must be double word (8 byte) aligned
5. The dst address must be double word (8 byte) aligned

Otherwise only a normal PCI store which takes its src value from
a register can be used. For these PCI store restriction 1 still applies.
Similarly 1 also applies to PCI loads.

It turns out zpci_max_write_size() instead implements stricter
conditions which prevents PCI block stores from being used where they
can and should be used. In particular instead of conditions 4 and 5 it
wrongly enforces both dst and src to be size aligned. This indirectly
covers condition 1 but also prevents many legal PCI block stores.

On top of the functional shortcomings the zpci_get_max_write_size() is
misnamed as it is used for both read and write size calculations. Rename
it to zpci_get_max_io_size() and implement the listed conditions
explicitly.

Following commit dccf78d39f ("kernel/Kconfig.kexec: drop
select of KEXEC for CRASH_DUMP") also drop automatic KEXEC
selection for s390 while set CONFIG_KEXEC=y explicitly for
defconfig and debug_defconfig targets. zfcpdump_defconfig
target gets CONFIG_KEXEC unset as result, which is right
and consistent with CONFIG_KEXEC_FILE besides.

77ed045e88 s390/compat: change default for CONFIG_COMPAT to "n"
31 bit support has been removed from the kernel more than eight years
ago. The last 31 bit distribution is many years older. There shouldn't be
any 31 bit code around anymore.

Therefore avoid providing an unused and only partially tested user space
interface and change the default for CONFIG_COMPAT from "yes" to "no".

8c6eabae38 iommufd: Add IOMMU_HWPT_INVALIDATE
In nested translation, the stage-1 page table is user-managed but cached
by the IOMMU hardware, so an update on present page table entries in the
stage-1 page table should be followed with a cache invalidation.

Add an IOMMU_HWPT_INVALIDATE ioctl to support such a cache invalidation.
It takes hwpt_id to specify the iommu_domain, and a multi-entry array to
support multiple invalidation data in one ioctl.

enum iommu_hwpt_invalidate_data_type is defined to tag the data type of
the entries in the multi-entry array.

c48a7c44a1 docs: kernel_feat.py: fix potential command injection
The kernel-feat directive passes its argument straight to the shell.
This is unfortunate and unnecessary.

Let's always use paths relative to $srctree/Documentation/ and use
subprocess.check_call() instead of subprocess.Popen(shell=True).

This also makes the code shorter.

This is analogous to commit 3231dd5862 ("docs: kernel_abi.py: fix
command injection") where we did exactly the same thing for
kernel_abi.py, somehow I completely missed this one.

1f4cac0f74 Documentation: constrain alabaster package to older versions
The 'alabaster' theme dropped support for Sphinx < v3.4:

    0.7.14 – 2024-01-08

    * Dropped support for Python 3.8 and earlier.
    * Dropped support for Sphinx 3.3 and earlier.
    [...]

(Source: https://alabaster.readthedocs.io/en/latest/changelog.html)

This manifests as an error when running 'make htmldocs' in a virtualenv
constructed from Documentation/sphinx/requirements.txt:

    Sphinx version error:
    The alabaster extension used by this project needs at least Sphinx v3.4; it therefore cannot be built with this version.

Raising the Sphinx version is not really a good option at this point,
since 3.x through 6.x have horrible performance regressions (7.x still
does, but not quite as bad).

Instead, constrain the 'alabaster' package to versions that still support
Sphinx 2.4.4.
