b426433c03 * MTD 
Simon Glass wanted to support binman's output properties in order to
 check their validity using the binding checks and proposed changes with
 the missing properties as well as a binman compatible.
 
 Krzysztof Kozlowski on his side shared a new yaml for describing
 Samsung's OneNAND interface.
 
 The interface with NVMEM has also been slightly improved/fixed,
 especially now that OTP are also supported in the NAND subsystem.
 
 Along with these changes, small cleanups have also been contributed
 around ID tables, structure sizes, arithmetic checks and comments.
 
 * Raw NAND subsystem
 
 Two small fixes, one in the Hynix vendor code for properly returning an
 error which might have been ignored and another in the Davinci driver to
 properly synchronize the controller with the gpio domain.
 
 * SPI NOR subsystem
 
 SPI NOR now uses div_u64() instead of div64_u64() in places where the
 divisor is 32 bits. Many 32 bit architectures can optimize this variant
 better than a full 64 bit divide.

Merge tag 'cxl-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull CXL updates from Dave Jiang:

 - Three CXL mailbox passthrough commands are added to support the
   populating and clearing of vendor debug logs:
     - Get Log Capabilities
     - Get Supported Log Sub-List Commands
     - Clear Log

 - Add support of Device Phyiscal Address (DPA) to Host Physical Address
   (HPA) translation for CXL events of cxl_dram and cxl_general media.

   This allows user space to figure out which CXL region the event
   occured via trace event.

 - Connect CXL to CPER reporting.

   If a device is configured for firmware first, CXL event records are
   not sent directly to the host. Those records are reported through EFI
   Common Platform Error Records (CPER). Add support to route the CPER
   records through the CXL sub-system in order to provide DPA to HPA
   translation and also event decoding and tracing. This is useful for
   users to determine which system issues may correspond to specific
   hardware events.

 - A number of misc cleanups and fixes:
     - Fix for compile warning of cxl_security_ops
     - Add debug message for invalid interleave granularity
     - Enhancement to cxl-test event testing
     - Add dev_warn() on unsupported mixed mode decoder

33e02dc69a sound updates for 6.10-rc1 
This one became bigger than usual, not in the total size but rather
 containing lots of small changes all over the places.  The majority of
 changes are about ASoC, especially SOF / Intel stuff, and we see an
 interesting work for ASoC DAPM graph visualization, while there are
 many other code cleanup and refactoring, too.
 
 Core:
 - A deadlock fix at device disconnection
 - A new tool dapm-graph for visualising the DAPM state
 
 ASoC:
 - Large updates throughout the Intel audio drivers
 - Fixes and clarifications for the DAPM documentation
 - Cleanups of accessors for driver data, module labelling, and for
   constification
 - Modernsation and cleanup work in the Mediatek drivers
 - Several fixes and features for the DaVinci I2S driver
 - New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
   Rockchip RK3308 and Texas Instruments PCM6240
 
 HD-audio:
 - Cleanup for CONFIG_PM dependencies
 - Cirrus HD-audio codec fixes and quirks
 
 Others:
 - Series of tree-wide fixes in Makefiles to use *-y
 - Additions of missing module descriptions
 - Scarlett2 USB mixer enhancements
 - A series of legacy emu10k1 fixes and improvements

Pull drm updates from Dave Airlie:
 "This is the main pull request for the drm subsystems for 6.10.

  In drivers the main thing is a new driver for ARM Mali firmware based
  GPUs, otherwise there are a lot of changes to amdgpu/xe/i915/msm and
  scattered changes to everything else.

  In the core a bunch of headers and Kconfig was refactored, along with
  the addition of a new panic handler which is meant to provide a user
  friendly message when a panic happens and graphical display is
  enabled.

1b294a1f35 Networking changes for 6.10. 
Core & protocols
 ----------------
 
  - Complete rework of garbage collection of AF_UNIX sockets.
    AF_UNIX is prone to forming reference count cycles due to fd passing
    functionality. New method based on Tarjan's Strongly Connected Components
    algorithm should be both faster and remove a lot of workarounds
    we accumulated over the years.
 
  - Add TCP fraglist GRO support, allowing chaining multiple TCP packets
    and forwarding them together. Useful for small switches / routers which
    lack basic checksum offload in some scenarios (e.g. PPPoE).
 
  - Support using SMP threads for handling packet backlog i.e. packet
    processing from software interfaces and old drivers which don't
    use NAPI. This helps move the processing out of the softirq jumble.
 
  - Continue work of converting from rtnl lock to RCU protection.
    Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
    labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
    MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
    neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
    information available via rtnetlink.
 
  - Small optimizations from Eric to UDP wake up handling, memory accounting,
    RPS/RFS implementation, TCP packet sizing etc.
 
  - Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
 
  - Support peek with an offset on TCP sockets.
 
  - Add MPTCP APIs for querying last time packets were received/sent/acked,
    and whether MPTCP "upgrade" succeeded on a TCP socket.
 
  - Add intra-node communication shortcut to improve SMC performance.
 
  - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
 
  - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
 
  - Add reset reasons for tracing what caused a TCP reset to be sent.
 
  - Introduce direction attribute for xfrm (IPSec) states.
    State can be used either for input or output packet processing.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
    This required touch-ups and renaming of a few existing users.
 
  - Add Endian-dependent __counted_by_{le,be} annotations.
 
  - Make building selftests "quieter" by printing summaries like
    "CC object.o" rather than full commands with all the arguments.
 
 Netfilter
 ---------
 
  - Use GFP_KERNEL to clone elements, to deal better with OOM situations
    and avoid failures in the .commit step.
 
 BPF
 ---
 
  - Add eBPF JIT for ARCv2 CPUs.
 
  - Support attaching kprobe BPF programs through kprobe_multi link in
    a session mode, meaning, a BPF program is attached to both function entry
    and return, the entry program can decide if the return program gets
    executed and the entry program can share u64 cookie value with return
    program. "Session mode" is a common use-case for tetragon and bpftrace.
 
  - Add the ability to specify and retrieve BPF cookie for raw tracepoint
    programs in order to ease migration from classic to raw tracepoints.
 
  - Add an internal-only BPF per-CPU instruction for resolving per-CPU
    memory addresses and implement support in x86, ARM64 and RISC-V JITs.
    This allows inlining functions which need to access per-CPU state.
 
  - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
    atomics in bpf_arena which can be JITed as a single x86 instruction.
    Support BPF arena on ARM64.
 
  - Add a new bpf_wq API for deferring events and refactor process-context
    bpf_timer code to keep common code where possible.
 
  - Harden the BPF verifier's and/or/xor value tracking.
 
  - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
 
  - Support bpf_tail_call_static() helper for BPF programs with GCC 13.
 
  - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
    program to have code sections where preemption is disabled.
 
 Driver API
 ----------
 
  - Skip software TC processing completely if all installed rules are
    marked as HW-only, instead of checking the HW-only flag rule by rule.
 
  - Add support for configuring PoE (Power over Ethernet), similar to
    the already existing support for PoDL (Power over Data Line) config.
 
  - Initial bits of a queue control API, for now allowing a single queue
    to be reset without disturbing packet flow to other queues.
 
  - Common (ethtool) statistics for hardware timestamping.
 
 Tests and tooling
 -----------------
 
  - Remove the need to create a config file to run the net forwarding tests
    so that a naive "make run_tests" can exercise them.
 
  - Define a method of writing tests which require an external endpoint
    to communicate with (to send/receive data towards the test machine).
    Add a few such tests.
 
  - Create a shared code library for writing Python tests. Expose the YAML
    Netlink library from tools/ to the tests for easy Netlink access.
 
  - Move netfilter tests under net/, extend them, separate performance tests
    from correctness tests, and iron out issues found by running them
    "on every commit".
 
  - Refactor BPF selftests to use common network helpers.
 
  - Further work filling in YAML definitions of Netlink messages for:
    nftables, team driver, bonding interfaces, vlan interfaces, VF info,
    TC u32 mark, TC police action.
 
  - Teach Python YAML Netlink to decode attribute policies.
 
  - Extend the definition of the "indexed array" construct in the specs
    to cover arrays of scalars rather than just nests.
 
  - Add hyperlinks between definitions in generated Netlink docs.
 
 Drivers
 -------
 
  - Make sure unsupported flower control flags are rejected by drivers,
    and make more drivers report errors directly to the application rather
    than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
 
  - Ethernet high-speed NICs:

Pull networking updates from Jakub Kicinski:
 "Core & protocols:

   - Complete rework of garbage collection of AF_UNIX sockets.

     AF_UNIX is prone to forming reference count cycles due to fd
     passing functionality. New method based on Tarjan's Strongly
     Connected Components algorithm should be both faster and remove a
     lot of workarounds we accumulated over the years.

   - Add TCP fraglist GRO support, allowing chaining multiple TCP
     packets and forwarding them together. Useful for small switches /
     routers which lack basic checksum offload in some scenarios (e.g.
     PPPoE).

   - Support using SMP threads for handling packet backlog i.e. packet
     processing from software interfaces and old drivers which don't use

Pull gpio updates from Bartosz Golaszewski
 "This was a quiet release cycle for the GPIO tree and so this
  pull-request is relatively small.

  We have one new driver, some minor improvements to the GPIO core code
  and across several drivers, some DT and documentation updates but in
  general nothing stands out or is controversial. All changes have spent
  time in next with no reported issues (or ones that were quickly
  fixed).

  GPIO core:
   - remove more unused legacy interfaces (after converting the last
     remaining users to better alternatives)
   - update kerneldocs
   - improve error handling and log messages in GPIO ACPI code
   - remove dead code (always true checks) from GPIOLIB

  New drivers:
   - add a driver for Intel Granite Rapids-D vGPIO

  Driver improvements:
   - use -ENOTSUPP consistently in gpio-regmap and gpio-pcie-idio-24
   - provide an ID table for gpio-cros-ec to avoid a driver name
     fallback check
   - add support for gpio-ranges for GPIO drivers supporting multiple
     GPIO banks
   - switch to using dynamic GPIO base in gpio-brcmstb
   - fix irq handling in gpio-npcm-sgpio
   - switch to memory mapped IO accessors in gpio-sch

 updates here are almost all driver specific ones.
 
  - Support for multi-word mode in the OMAP2 McSPI driver.
  - Overhaul of the PXA2xx driver, mostly API updates.
  - A number of DT binding conversions.

6bfd2d442a Updates for the interrupt subsystem: 
- Core code:
 
    - Interrupt storm detection for the lockup watchdog:
 
      Lockups which are caused by interrupt storms are not easy to debug
      because there is no information about the events which make the lockup
      detector trigger.
 
      To make this more user friendly, provide an extenstion to interrupt
      statistics which allows to take snapshots and an interface to retrieve
      the delta to the snapshot. Use this new mechanism in the watchdog code
      to do a two stage lockup analysis by taking the snapshot and printing
      the deltas for the topmost active interrupts on the second trigger.
 
      Note: This contains both the interrupt and the watchdog changes as
      the latter depend on the former obviously.
 
   - Avoid summation loops in the /proc/interrupts output and use the global
     counter when possible
 
   - Skip suspended interrupts on CPU hotplug operations to ensure that they
     are not delivered before the system resumes the device drivers when
     coming out of suspend.
 
   - On CPU hot-unplug interrupts which are affine to the outgoing CPU are
     migrated to a different CPU in the affinity mask. This can fail when
     the CPUs have no vectors left. Instead of giving up try to migrate it
     to any online CPU and thereby breaking the affinity setting in order to
     prevent a stale device interrupt which targets an offline CPU
 
   - The usual small cleanups
 
  - Driver code:
 
   - Support for the RISCV AIA MSI controller
 
   - Make the interrupt allocation for the Loongson PCH controller more
     flexible to prevent vector exhaustion
 
   - The usual set of cleanups and fixes all over the place

defa9cca02 dt-bindings: net: bluetooth: Add MediaTek MT7921S SDIO Bluetooth 
The MediaTek MT7921S is a WiFi/Bluetooth combo chip that works over
SDIO. WiFi and Bluetooth are separate SDIO functions within the chip.
While the Bluetooth SDIO function is fully discoverable, the chip has
a pin that can reset just the Bluetooth core, as opposed to the full
chip. This should be described in the device tree.

Add a device tree binding for the Bluetooth SDIO function of the MT7921S
specifically to document the reset line. This binding is based on the MMC
controller binding, which specifies one device node per SDIO function.

====================
pull-request: bpf-next 2024-05-13

We've added 119 non-merge commits during the last 14 day(s) which contain
a total of 134 files changed, 9462 insertions(+), 4742 deletions(-).

The main changes are:

1) Add BPF JIT support for 32-bit ARCv2 processors, from Shahab Vahedi.

2) Add BPF range computation improvements to the verifier in particular
   around XOR and OR operators, refactoring of checks for range computation
   and relaxing MUL range computation so that src_reg can also be an unknown
   scalar, from Cupertino Miranda.

3) Add support to attach kprobe BPF programs through kprobe_multi link in
   a session mode, meaning, a BPF program is attached to both function entry
   and return, the entry program can decide if the return program gets
   executed and the entry program can share u64 cookie value with return
   program. Session mode is a common use-case for tetragon and bpftrace,
   from Jiri Olsa.

4) Fix a potential overflow in libbpf's ring__consume_n() and improve libbpf
   as well as BPF selftest's struct_ops handling, from Andrii Nakryiko.

5) Improvements to BPF selftests in context of BPF gcc backend,
   from Jose E. Marchesi & David Faust.

6) Migrate remaining BPF selftest tests from test_sock_addr.c to prog_test-
   -style in order to retire the old test, run it in BPF CI and additionally
   expand test coverage, from Jordan Rife.

7) Big batch for BPF selftest refactoring in order to remove duplicate code
   around common network helpers, from Geliang Tang.

8) Another batch of improvements to BPF selftests to retire obsolete
   bpf_tcp_helpers.h as everything is available vmlinux.h,
   from Martin KaFai Lau.

9) Fix BPF map tear-down to not walk the map twice on free when both timer
   and wq is used, from Benjamin Tissoires.

10) Fix BPF verifier assumptions about socket->sk that it can be non-NULL,
    from Alexei Starovoitov.

11) Change BTF build scripts to using --btf_features for pahole v1.26+,
    from Alan Maguire.

12) Small improvements to BPF reusing struct_size() and krealloc_array(),
    from Andy Shevchenko.

13) Fix s390 JIT to emit a barrier for BPF_FETCH instructions,
    from Ilya Leoshkevich.

14) Extend TCP ->cong_control() callback in order to feed in ack and
    flag parameters and allow write-access to tp->snd_cwnd_stamp
    from BPF program, from Miao Xu.

15) Add support for internal-only per-CPU instructions to inline
    bpf_get_smp_processor_id() helper call for arm64 and riscv64 BPF JITs,
    from Puranjay Mohan.

16) Follow-up to remove the redundant ethtool.h from tooling infrastructure,
    from Tushar Vyavahare.

17) Extend libbpf to support "module:<function>" syntax for tracing
    programs, from Viktor Malik.

Pull hardening updates from Kees Cook:
 "The bulk of the changes here are related to refactoring and expanding
  the KUnit tests for string helper and fortify behavior.

  Some trivial strncpy replacements in fs/ were carried in my tree. Also
  some fixes to SCSI string handling were carried in my tree since the
  helper for those was introduce here. Beyond that, just little fixes
  all around: objtool getting confused about LKDTM+KCFI, preparing for
  future refactors (constification of sysctl tables, additional
  __counted_by annotations), a Clang UBSAN+i386 crash fix, and adding
  more options in the hardening.config Kconfig fragment.

  Summary:

   - selftests: Add str*cmp tests (Ivan Orlov)

   - __counted_by: provide UAPI for _le/_be variants (Erick Archer)

   - Various strncpy deprecation refactors (Justin Stitt)

   - stackleak: Use a copy of soon-to-be-const sysctl table (Thomas
     Weißschuh)

   - UBSAN: Work around i386 -regparm=3 bug with Clang prior to

Merge cpufreq updates for 6.10:

 - Rework the handling of disabled turbo in the intel_pstate driver and
   make it update the maximum CPU frequency consistently regardless of
   the reason on top of a number of cleanups (Rafael Wysocki).

 - Add missing checks for NULL .exit() cpufreq driver callback to the
   cpufreq core (Viresh Kumar).

 - Prevent pulicy->max from going above the frequency QoS maximum value
   when cpufreq_frequency_table_verify() is used (Xuewen Yan).

 - Prevent a negative CPU number or frequency value from being printed
   if they are really large (Joshua Yeong).

   performance (Perry Yuan).

 - Enable CPPC v2 for certain processors in the family 17H, as requested
   by TR40 processor users who expect improved performance and lower
   system temperature (Perry Yuan).

 - Change latency and delay values to be read from platform firmware
   firstly for more accurate timing (Perry Yuan).

 - A new quirk is introduced for supporting amd-pstate on legacy
   processors which either lack CPPC capability, or only only have CPPC
   v2 capability (Perry Yuan).

 - Sun50i: Add support for opp_supported_hw, H616 platform and general
   cleanups (Andre Przywara, Martin Botka, Brandon Cheo Fusi, Dan
   Carpenter, Viresh Kumar).

 - CPPC: Fix possible null pointer dereference (Aleksandr Mishin).

f122668ddc ARC: Add eBPF JIT support 
This will add eBPF JIT support to the 32-bit ARCv2 processors. The
implementation is qualified by running the BPF tests on a Synopsys HSDK
board with "ARC HS38 v2.1c at 500 MHz" as the 4-core CPU.

The test_bpf.ko reports 2-10 fold improvements in execution time of its
tests. For instance:

test_bpf: #33 tcpdump port 22 jited:0 704 1766 2104 PASS
test_bpf: #33 tcpdump port 22 jited:1 120  224  260 PASS

test_bpf: #141 ALU_DIV_X: 4294967295 / 4294967295 = 1 jited:0 238 PASS
test_bpf: #141 ALU_DIV_X: 4294967295 / 4294967295 = 1 jited:1  23 PASS

test_bpf: #776 JMP32_JGE_K: all ... magnitudes jited:0 2034681 PASS
test_bpf: #776 JMP32_JGE_K: all ... magnitudes jited:1 1020022 PASS

Deployment and structure
------------------------
The related codes are added to "arch/arc/net":

- bpf_jit.h       -- The interface that a back-end translator must provide
- bpf_jit_core.c  -- Knows how to handle the input eBPF byte stream
- bpf_jit_arcv2.c -- The back-end code that knows the translation logic

The bpf_int_jit_compile() at the end of bpf_jit_core.c is the entrance
to the whole process. Normally, the translation is done in one pass,
namely the "normal pass". In case some relocations are not known during
this pass, some data (arc_jit_data) is allocated for the next pass to
come. This possible next (and last) pass is called the "extra pass".

1. Normal pass       # The necessary pass
     1a. Dry run       # Get the whole JIT length, epilogue offset, etc.
     1b. Emit phase    # Allocate memory and start emitting instructions
2. Extra pass        # Only needed if there are relocations to be fixed
     2a. Patch relocations

Support status
--------------
The JIT compiler supports BPF instructions up to "cpu=v4". However, it
does not yet provide support for:

- Tail calls
- Atomic operations
- 64-bit division/remainder
- BPF_PROBE_MEM* (exception table)

The result of "test_bpf" test suite on an HSDK board is:

hsdk-lnx# insmod test_bpf.ko test_suite=test_bpf

  test_bpf: Summary: 863 PASSED, 186 FAILED, [851/851 JIT'ed]

All the failing test cases are due to the ones that were not JIT'ed.
Categorically, they can be represented as:

  .-----------.------------.-------------.
  | test type |   opcodes  | # of cases  |
  |-----------+------------+-------------|
  | atomic    | 0xC3, 0xDB |         149 |
  | div64     | 0x37, 0x3F |          22 |
  | mod64     | 0x97, 0x9F |          15 |
  `-----------^------------+-------------|
                           | (total) 186 |
                           `-------------'

Setup: build config
-------------------
The following configs must be set to have a working JIT test:

  CONFIG_BPF_JIT=y
  CONFIG_BPF_JIT_ALWAYS_ON=y
  CONFIG_TEST_BPF=m

The following options are not necessary for the tests module,
but are good to have:

  CONFIG_DEBUG_INFO=y             # prerequisite for below
  CONFIG_DEBUG_INFO_BTF=y         # so bpftool can generate vmlinux.h

  CONFIG_FTRACE=y                 #
  CONFIG_BPF_SYSCALL=y            # all these options lead to
  CONFIG_KPROBE_EVENTS=y          # having CONFIG_BPF_EVENTS=y
  CONFIG_PERF_EVENTS=y            #

Some BPF programs provide data through /sys/kernel/debug:
  CONFIG_DEBUG_FS=y
arc# mount -t debugfs debugfs /sys/kernel/debug

Setup: elfutils
---------------
The libdw.{so,a} library that is used by pahole for processing
the final binary must come from elfutils 0.189 or newer. The
support for ARCv2 [1] has been added since that version.

[1]
https://sourceware.org/git/?p=elfutils.git;a=commit;h=de3d46b3e7

Setup: pahole
-------------
The line below in linux/scripts/Makefile.btf must be commented out:

pahole-flags-$(call test-ge, $(pahole-ver), 121) += --btf_gen_floats

Or else, the build will fail:

$ make V=1
  ...
  BTF     .btf.vmlinux.bin.o
pahole -J --btf_gen_floats                    \
       -j --lang_exclude=rust                 \
       --skip_encoding_btf_inconsistent_proto \
       --btf_gen_optimized .tmp_vmlinux.btf
Complex, interval and imaginary float types are not supported
Encountered error while encoding BTF.
  ...
  BTFIDS  vmlinux
./tools/bpf/resolve_btfids/resolve_btfids vmlinux
libbpf: failed to find '.BTF' ELF section in vmlinux
FAILED: load BTF from vmlinux: No data available

This is due to the fact that the ARC toolchains generate
"complex float" DIE entries in libgcc and at the moment, pahole
can't handle such entries.

Running the tests
-----------------
host$ scp /bld/linux/lib/test_bpf.ko arc:
arc # sysctl net.core.bpf_jit_enable=1
arc # insmod test_bpf.ko test_suite=test_bpf
      ...
      test_bpf: #1048 Staggered jumps: JMP32_JSLE_X jited:1 697811 PASS
      test_bpf: Summary: 863 PASSED, 186 FAILED, [851/851 JIT'ed]

- Yuriy Kolerov for testing and troubleshooting
- Vladimir Isaev for the pahole workaround
- Sergey Matyukevich for paving the road by adding the interpreter support

a06b80e830 i2c: add zhaoxin i2c controller driver 
Add Zhaoxin I2C controller driver. It provides the access to the i2c
busses, which connects to the touchpad, eeprom, I2S, etc.

Zhaoxin I2C controller has two separate busses, so may accommodate up
to two I2C adapters. Those adapters are listed in the ACPI namespace
with the IIC1D17 HID, and probed by a platform driver.

The driver works with IRQ mode, and supports basic I2C features. Flags
I2C_AQ_NO_ZERO_LEN and I2C_AQ_COMB_WRITE_THEN_READ are used to limit
the unsupported access.

drivers for any part of the display block OR the GPU. Separate the
latter, as it's both a functionally separate block and is of
interest to different folks.

8bbe44ce65 MAINTAINERS: Remove {ehci,uhci}-platform.c from ARM/VT8500 entry 
ARM/VT8500 is marked as Orphan. It includes ehci-platform.c and
uhci-platform.c in its file list, even though uhci-platform.c is included
from uhci-hcd.c and ehci-platform.c is used by several platforms.
Listing those files as part of an orphan platform does not add value,
even more so since they are marked as supported as part of generic ehci
and uhci support. Drop the files from the ARM/VT8500 entry.

Commit 12fb28ea6b ("EINJ: Add CXL error type support") adds the header
file include/linux/einj-cxl.h, but then adds a file entry with cxl-einj.h
(note the swapping of words) to the COMPUTE EXPRESS LINK (CXL) section.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

get_maintainer.pl can only return commit_signer history for file
include/linux/einj-cxl.h because the entry in MAINTAINERS is wrong.
Correct the entry so that the full MAINTAINER list is returned.

21cbc1058a Arm SCMI updates for v6.10 
1. Basic support for SCMI v3.2 pincontrol protocol
 
    SCMI v3.2 introduces pincontrol protocol which is intended for
    controlling pins and their configuration. The pin control protocol
    provides commands to:
    - List the pins, groups of pins, available functions, and their
      association with each other.
    - Set the parameter configuration and multiplexing of the pins or
      groups of pins
    - Optionally request exclusive access to a pin or group of pins.
    - Optionally configure the permissions of an agent to access a pin
      or group of pins.
 
   These changes adds basic support for the same in the SCMI core layer
   and an implementation of the generic scmi-pinctrl driver with associated
   DT bindings.
 
 2. Framework support for multiple vendors custom protocols
 
    With the fixed space for vendor protocols, the possibility of having
    multiple vendors implementing distinct SCMI vendor protocols with
    the same overlapping protocol number is very high and with the need
    to support them all in a single kernel image or a module is also high.
 
    In order to implement the same we assume:
    - vendor protocols has to be tagged at build time with a vendor_id
    - vendor protocols could also optionally be tagged at build time with
      sub_vendor_id and implementation version
 
   At the initialisation all the built vendor protocols are registered
   with the SCMI core using a key derived from the above tags
 
 3. Logging and tracing improvements
 
    This includes using dev_err_probe() to bail out from probe, adding
    message dump traces for bad and unexpected replies and widening of
    the tag buffer in trace_scmi_dump_msg to allow diverse tag names
 
 4. Miscellaneous updates or improvements
 
    This includes adding the accessor function get_max_msg_size() used
    in pinctl protocol, updation of dt-bindings examples for protocol@13
    to promote new bindings and simplification of scmi_devm_notifier_unregister

Arm SCMI updates for v6.10

1. Basic support for SCMI v3.2 pincontrol protocol

   SCMI v3.2 introduces pincontrol protocol which is intended for
   controlling pins and their configuration. The pin control protocol
   provides commands to:
   - List the pins, groups of pins, available functions, and their
     association with each other.
   - Set the parameter configuration and multiplexing of the pins or
     groups of pins
   - Optionally request exclusive access to a pin or group of pins.
   - Optionally configure the permissions of an agent to access a pin
     or group of pins.

  These changes adds basic support for the same in the SCMI core layer
  and an implementation of the generic scmi-pinctrl driver with associated
  DT bindings.

2. Framework support for multiple vendors custom protocols

   With the fixed space for vendor protocols, the possibility of having
   multiple vendors implementing distinct SCMI vendor protocols with
   the same overlapping protocol number is very high and with the need
   to support them all in a single kernel image or a module is also high.

   In order to implement the same we assume:
   - vendor protocols has to be tagged at build time with a vendor_id
   - vendor protocols could also optionally be tagged at build time with
     sub_vendor_id and implementation version

  At the initialisation all the built vendor protocols are registered
  with the SCMI core using a key derived from the above tags

3. Logging and tracing improvements

   This includes using dev_err_probe() to bail out from probe, adding
   message dump traces for bad and unexpected replies and widening of
   the tag buffer in trace_scmi_dump_msg to allow diverse tag names

4. Miscellaneous updates or improvements

   This includes adding the accessor function get_max_msg_size() used
   in pinctl protocol, updation of dt-bindings examples for protocol@13
   to promote new bindings and simplification of scmi_devm_notifier_unregister

40b561e501 TEE driver for Trusted Services 
This introduces a TEE driver for Trusted Services [1].
 
 Trusted Services is a TrustedFirmware.org project that provides a
 framework for developing and deploying device Root of Trust services in
 FF-A [2] Secure Partitions. The project hosts the reference
 implementation of Arm Platform Security Architecture [3] for Arm
 A-profile devices.
 
 The FF-A Secure Partitions are accessible through the FF-A driver in
 Linux. However, the FF-A driver doesn't have a user space interface so
 user space clients currently cannot access Trusted Services. The goal of
 this TEE driver is to bridge this gap and make Trusted Services
 functionality accessible from user space.

02c2c1900f Qualcomm driver updates for v6.10 
The Qualcomm SCM driver initialization order is improved, to avoid any
 potential for a client to find a half-initialized SCM instance.
 The handling of download mode bits is updated to not attempt
 QCOM_SCM_BOOT_SET_DLOAD_MODE if a io-address for the update is
 specified, and that path is changed to perform a read-modify-write to
 avoid updating unrelated bits.  Error handling is corrected in the
 peripheral authentication service (PAS) functions, to release
 interconnect bandwidth votes in the case of an error. An unwanted error
 print on allocation error is also removed from this code path.
 
 The QSEECOM allow list is marked __maybe_unused to avoid build warnings
 when built with !OF. The error handling related to the interconnect API
 is cleaned up to avoid handling the impossible IS_ERR() condition.
 
 initcall level is bumped to "core" for cmd-db and rpmh-rsc, as dependent
 drivers like regulators, interconnects and clocks are registered at this
 level.
 
 Another attempt is made to remove the strncpy() usage in cmd-db, this
 time with strtomem_pad() which has the correct characteristics.
 
 The bwmon regmap cache is changed to maple tree.
 
 After an attempt to add missing MODULE_DEVICE_TABLEs to debug drivers,
 the intention of not having them automatically load is documented.
 
 Operations on the pmic_glink client list is put under mutual exclusion,
 to avoid races when clients are being registered. pmic_glink client
 registered after the firmware notification arrived was not informed that
 the firmware was up, this is resolved.
 
 More DSPs and the apss subsystem is added to the Qualcomm sleep stats driver.
 
 Checks for in-flight regulator requests in the RPMh RSC driver is
 improved to deal with the fact that these occupy multiple registers, so
 it's insufficient to just to direct address comparison.
 
 The socinfo drivers learns about X1 Elite and SMB2360 PMIC.
 
 The maintainers entry is split between the linux-arm-msm list and
 subset that is maintained in the qcom-soc tree, to avoid some confusion
 about maintainership.

46671fd3e3 STM32 Firewall bus for v6.10, round 1 
Highlights:
 ---------
 
 Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x
 platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers
 register to the framework to offer firewall services such as access
 granting.
 
 This series of patches is a new approach on the previous STM32 system
 bus, history is available here:
 https://lore.kernel.org/lkml/20230127164040.1047583/
 
 The need for such framework arises from the fact that there are now
 multiple hardware firewalls implemented across multiple products.
 Drivers are shared between different products, using the same code.
 When it comes to firewalls, the purpose mostly stays the same: Protect
 hardware resources. But the implementation differs, and there are
 multiple types of firewalls: peripheral, memory, ...
 
 Some hardware firewall controllers such as the RIFSC implemented on
 STM32MP2x platforms may require to take ownership of a resource before
 being able to use it, hence the requirement for firewall services to
 take/release the ownership of such resources.
 
 On the other hand, hardware firewall configurations are becoming
 more and more complex. These mecanisms prevent platform crashes
 or other firewall-related incoveniences by denying access to some
 resources.
 
 The stm32 firewall framework offers an API that is defined in
 firewall controllers drivers to best fit the specificity of each
 firewall.
 
 For every peripherals protected by either the ETZPC or the RIFSC, the
 firewall framework checks the firewall controlelr registers to see if
 the peripheral's access is granted to the Linux kernel. If not, the
 peripheral is configured as secure, the node is marked populated,
 so that the driver is not probed for that device.
 
 The firewall framework relies on the access-controller device tree
 binding. It is used by peripherals to reference a domain access
 controller. In this case a firewall controller. The bus uses the ID
 referenced by the access-controller property to know where to look
 in the firewall to get the security configuration for the peripheral.
 This allows a device tree description rather than a hardcoded peripheral
 table in the bus driver.
 
 The STM32 ETZPC device is responsible for filtering accesses based on
 security level, or co-processor isolation for any resource connected
 to it.
 
 The RIFSC is responsible for filtering accesses based on Compartment
 ID / security level / privilege level for any resource connected to
 it.

https://lore.kernel.org/lkml/20230127164040.1047583/

The need for such framework arises from the fact that there are now
multiple hardware firewalls implemented across multiple products.
Drivers are shared between different products, using the same code.
When it comes to firewalls, the purpose mostly stays the same: Protect
hardware resources. But the implementation differs, and there are
multiple types of firewalls: peripheral, memory, ...

Some hardware firewall controllers such as the RIFSC implemented on
STM32MP2x platforms may require to take ownership of a resource before
being able to use it, hence the requirement for firewall services to
take/release the ownership of such resources.

On the other hand, hardware firewall configurations are becoming
more and more complex. These mecanisms prevent platform crashes
or other firewall-related incoveniences by denying access to some
resources.

The stm32 firewall framework offers an API that is defined in
firewall controllers drivers to best fit the specificity of each
firewall.

For every peripherals protected by either the ETZPC or the RIFSC, the
firewall framework checks the firewall controlelr registers to see if
the peripheral's access is granted to the Linux kernel. If not, the
peripheral is configured as secure, the node is marked populated,
so that the driver is not probed for that device.

The firewall framework relies on the access-controller device tree
binding. It is used by peripherals to reference a domain access
controller. In this case a firewall controller. The bus uses the ID
referenced by the access-controller property to know where to look
in the firewall to get the security configuration for the peripheral.
This allows a device tree description rather than a hardcoded peripheral
table in the bus driver.

The STM32 ETZPC device is responsible for filtering accesses based on
security level, or co-processor isolation for any resource connected
to it.

The RIFSC is responsible for filtering accesses based on Compartment
ID / security level / privilege level for any resource connected to
it.

9c0beb6b29 platform/x86: wmi: Add MSI WMI Platform driver 
Add a new driver for the MSI WMI Platform interface. The underlying
ACPI WMI interface supports many features, but so far only reading
of fan speed sensors is implemented.

The driver was reverse-engineered based on a user request to the
lm-sensors project, see the github issue for details.

The ACPI WMI interface used by this driver seems to use the same
embedded controller interface as the msi-ec driver, but supports
automatic discovery of supported machines without relying on a
DMI whitelist.

The driver was tested by the user who created the github issue.

a4aded1ff5 dt-bindings: rng: Add vmgenid support 
Virtual Machine Generation ID driver was introduced in commit
af6b54e2b5 ("virt: vmgenid: notify RNG of VM fork and supply
generation ID"), as an ACPI only device.

VMGenID specification http://go.microsoft.com/fwlink/?LinkId=260709
defines a mechanism for the BIOS/hypervisors to communicate to the
virtual machine that it is executed with a different configuration (e.g.
snapshot execution or creation from a template).  The guest operating
system can use the notification for various purposes such as
re-initializing its random number generator etc.

As per the specs, hypervisor should provide a globally unique
identified, or GUID via ACPI.

This patch tries to mimic the mechanism to provide the same
functionality which is for a hypervisor/BIOS to notify the virtual
machine when it is executed with a different configuration.

As part of this support the devicetree bindings requires the hypervisors
or BIOS to provide a memory address which holds the GUID and an IRQ
which is used to notify when there is a change in the GUID.  The memory
exposed in the DT should follow the rules defined in the vmgenid spec
mentioned above.

Reason for this change: Chosing ACPI or devicetree is an intrinsic part
of an hypervisor design.  Without going into details of why a hypervisor
would chose DT over ACPI, we would like to highlight that the
hypervisors that have chose devicetree and now want to make use of the
vmgenid functionality cannot do so today because vmgenid is an ACPI only
device.  This forces these hypervisors to change their design which
could have undesirable impacts on their use-cases, test-scenarios etc.

The point of vmgenid is to provide a mechanism to discover a GUID when
the execution state of a virtual machine changes and the simplest way to
do it is pass a memory location and an interrupt via devicetree.  It
would complicate things unnecessarily if instead of using devicetree, we
try to implement a new protocol or modify other protocols to somehow
provide the same functionility.

We believe that adding a devicetree binding for vmgenid is a simpler,
better alternative to provide the same functionality and will allow such
hypervisors as mentioned above to continue using devicetree.

More references to the vmgenid specs are found below.

net: intel: start The Great Code Dedup + Page Pool for iavf

Alexander Lobakin says:

Here's a two-shot: introduce {,Intel} Ethernet common library (libeth and
libie) and switch iavf to Page Pool. Details are in the commit messages;
here's a summary:

Not a secret there's a ton of code duplication between two and more Intel
ethernet modules. Before introducing new changes, which would need to be
copied over again, start decoupling the already existing duplicate
functionality into a new module, which will be shared between several
Intel Ethernet drivers. The first name that came to my mind was
"libie" -- "Intel Ethernet common library". Also this sounds like
"lovelie" (-> one word, no "lib I E" pls) and can be expanded as
"lib Internet Explorer" :P
The "generic", pure-software part is placed separately, so that it can be
easily reused in any driver by any vendor without linking to the Intel
pre-200G guts. In a few words, it's something any modern driver does the
same way, but nobody moved it level up (yet).
The series is only the beginning. From now on, adding every new feature
or doing any good driver refactoring will remove much more lines than add
for quite some time. There's a basic roadmap with some deduplications
planned already, not speaking of that touching every line now asks:
"can I share this?". The final destination is very ambitious: have only
one unified driver for at least i40e, ice, iavf, and idpf with a struct
ops for each generation. That's never gonna happen, right? But you still
can at least try.
PP conversion for iavf lands within the same series as these two are tied
closely. libie will support Page Pool model only, so that a driver can't
use much of the lib until it's converted. iavf is only the example, the
rest will eventually be converted soon on a per-driver basis. That is
when it gets really interesting. Stay tech.

dbc8fc9d6d powerpc/papr_scm: Move duplicate definitions to common header files 
papr_scm and ndtest share common PDSM payload structs like
nd_papr_pdsm_health. Presently these structs are duplicated across
papr_pdsm.h and ndtest.h header files. Since 'ndtest' is essentially
arch independent and can run on platforms other than PPC64, a way
needs to be deviced to avoid redundancy and duplication of PDSM
structs in future.

So the patch proposes moving the PDSM header from arch/powerpc/include-
-/uapi/ to the generic include/uapi/linux directory. Also, there
are some #defines common between papr_scm and ndtest which are not
exported to the user space. So, move them to a header file which
can be shared across ndtest and papr_scm via newly introduced
include/linux/papr_scm.h.

virtual GPIOs. On SoCs with limited physical pins on the package, the
physical pins controlled by this driver would be exposed on an external
device such as a BMC or CPLD. The virtual GPIO registers are an
