efdfcd40ad lkmm: Add documentation and mailing list 
This pull request contains documentation updates from Andrea Parri and
 Akira Yokosawa.  Also, there is now an lkmm@lists.linux.dev, and Boqun
 Feng's update adds this to the LKMM MAINTAINERS entry.
 
 Not included in this pull request are a couple of more commits from
 Puranjay Mohan adding more atomic operations to LKMM, but these await a
 herdtools7 release that includes tool-side support for this functionality.
 With luck, I will send a separate pull request for these later in the
 merge window.

78567e2bc7 cgroup: Changes for v6.12 
- cpuset isolation improvements.
 
 - cpuset cgroup1 support is split into its own file behind the new config
   option CONFIG_CPUSET_V1. This makes it the second controller which makes
   cgroup1 support optional after memcg.
 
 - Handling of unavailable v1 controller handling improved during cgroup1
   mount operations.
 
 - union_find applied to cpuset. It makes code simpler and more efficient.
 
 - Reduce spurious events in pids.events.
 
 - Cleanups and other misc changes.
 
 - Contains a merge of cgroup/for-6.11-fixes to receive cpuset fixes that
   further changes build upon.

2f27fce671 sound updates for 6.12-rc1 
A fairly big update at this time, both in core and driver sides.
 
 The core received rewrites in PCM buffer allocation handling and
 locking optimizations, PCM rate updates followed by lots of cleanups.
 
 In ASoC side, the legacy Intel drivers have been deprecated by AVS
 drivers which leaded to the significant amount of code reduction.
 SoundWire driver updates and other cleanups contributed more code
 reduction, too.
 
 USB-audio driver received a large cleanup of its big quirk table, and
 the old snd_print*() API usages in many legacy drivers are replaced
 with the standard print API.
 
 Here are some highlights:
 
 Core:
 - More optimized locking in ALSA control code
 - Rewrites of memalloc helpers for better DMA API usage
 - Drop of obsoleted vmalloc PCM buffer helper API
 - Continued MIDI2 UMP updates
 - Support of a new user-space driven timer instance
 - Update for more PCM support rates and cleanups
 - Xrun counter report in the proc files
 
 ASoC:
 - Continued simplification and cleanup works for ASoC
 - Extensive cleanups and refactoring of the Soundwire drivers
 - Removal of Intel machine support obsoleted by the AVS driver
 - Lots of DT schema conversions
 - Machine support for many AMD and Intel x86 platforms
 - Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320
   SoundWire and rev C, and Texas Instruments TAS2563
 
 USB-audio:
 - Add support of multiple control interfaces
 - A large rewrite of quirk table with macros
 - Support for RME Digiface USB
 
 HD-audio:
 - Cleanup of quirk code for Samsung Galaxy laptops
 - Clean up of detection of Cirrus codecs
 - C-Media CM9825 HD-audio codec support
 
 Others:
 - Rewrites to standard print API in a lot of legacy drivers

837acb691c MAINTAINERS: adjust file entry in INTEL MID PLATFORM 
Commit 5f1cda5110 ("platform/x86: intel_scu_wdt: Move intel_scu_wdt.h to
x86 subfolder") moves intel-mid_wdt.h in ./include/linux/platform_data into
the x86 subdirectory, but misses to adjust the INTEL MID PLATFORM section,
which is referring to this file.

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

Adjust the file entry to this header file movement.

a940d9a43e soc: arm platform updates for 6.12 
Most of these updates are for removing dead code on the Samsung S3C,
 NXP i.MX, TI OMAP and  TI DaVinci platforms, though this appears to be
 a coincidence. There are also cleanups for the Marvell Orion family and
 the Arm integrator series and a Kconfig change for Broadcom.

b8979c6b4d soc: driver updates for 6.12 
The driver updates seem larger this time around, with changes
 is many of the SoC specific drivers, both the custom drivers/soc
 ones and the closely related subsystems (memory, bus, firmware,
 reset, ...).
 
 The at91 platform gains support for sam9x7 chips in the soc and
 power management code. This is the latest variant of one of the
 oldest still supported SoC families, using the ARM9 (ARMv5) core.
 
 As usual, the qualcomm snapdragon platform gets a ton of updates in many
 of their drivers to add more features and additional SoC support. Most
 of these are somewhat firmware related as the platform has a number of
 firmware based interfaces to the kernel. A notable addition here is the
 inclusion of trace events to two of these drivers.
 
 Herve Codina and Christophe Leroy are now sending updates for
 drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
 and Arm specific platforms and has previously been problematic to
 maintain. The first update here contains support for newer PowerPC
 variants and some cleanups.
 
 The turris mox firmware driver has a number of updates, mostly cleanups.
 
 The Arm SCMI firmware driver gets a major rework to modularize
 the existing code into separately loadable drivers for the various
 transports, the addition of custom NXP i.MX9 interfaces and a
 number of smaller updates.
 
 The Arm FF-A firmware driver gets a feature update to support
 the v1.2 version of the specification.
 
 The reset controller drivers have some smaller cleanups and a newly
 added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
 
 The memory controller drivers get some cleanups and refactoring
 for Tegra, TI, Freescale/NXP and a couple more platforms.
 
 Finally there are lots of minor updates to firmware (raspberry pi,
 tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
 mediatek) drivers and their DT bindings.

New SoC support for Broadcom bcm2712 (Raspberry Pi 5) and Renesas
 R9A09G057 (RZ/V2H(P)) and Qualcomm Snapdragon 414 (MSM8929), all three
 of these are variants of already supported chips, in particular the last
 one is almost identical to MSM8939.
 
 Lots of updates to Mediatek, ASpeed, Rockchips, Amlogic, Qualcomm,
 STM32, NXP i.MX, Sophgo, TI K3, Renesas, Microchip at91, NVIDIA Tegra,
 and T-HEAD.
 
 The added Qualcomm platform support once again dominates the changes,
 with seven phones and three laptops getting added in addition to
 many new features on existing machines. The Snapdragon X1E support
 specifically keeps improving.
 
 The other new machines are:
 
  - eight new machines using various 64-bit Rockchips SoCs, both
    on the consumer/gaming side and developer boards
  - three industrial boards with 64-bit i.MX, which is a very
    low number for them.
  - four more servers using a 32-bit Speed BMC
  - three boards using STM32MP1 SoCs
  - one new machine each using allwinner, amlogic, broadcom
    and renesas chips.

Merge tag 'lsm-pr-20240911' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull lsm updates from Paul Moore:

 - Move the LSM framework to static calls

   This transitions the vast majority of the LSM callbacks into static
   calls. Those callbacks which haven't been converted were left as-is
   due to the general ugliness of the changes required to support the
   static call conversion; we can revisit those callbacks at a future
   date.

 - Add the Integrity Policy Enforcement (IPE) LSM

   This adds a new LSM, Integrity Policy Enforcement (IPE). There is
   plenty of documentation about IPE in this patches, so I'll refrain
   from going into too much detail here, but the basic motivation behind
   IPE is to provide a mechanism such that administrators can restrict
   execution to only those binaries which come from integrity protected
   storage, e.g. a dm-verity protected filesystem. You will notice that
   IPE requires additional LSM hooks in the initramfs, dm-verity, and
   fs-verity code, with the associated patches carrying ACK/review tags
   from the associated maintainers. We couldn't find an obvious
   maintainer for the initramfs code, but the IPE patchset has been

 - Move the lifecycle management of the LSM blobs to the LSM framework

   Management of the LSM blobs (the LSM state buffers attached to
   various kernel structs, typically via a void pointer named "security"
   or similar) has been mixed, some blobs were allocated/managed by
   individual LSMs, others were managed by the LSM framework itself.

   Starting with this pull we move management of all the LSM blobs,
   minus the XFRM blob, into the framework itself, improving consistency
   across LSMs, and reducing the amount of duplicated code across LSMs.
   Due to some additional work required to migrate the XFRM blob, it has
   been left as a todo item for a later date; from a practical
   standpoint this omission should have little impact as only SELinux
   provides a XFRM LSM implementation.

 - Fix problems with the LSM's handling of F_SETOWN

   The LSM hook for the fcntl(F_SETOWN) operation had a couple of
   problems: it was racy with itself, and it was disconnected from the
   associated DAC related logic in such a way that the LSM state could
   be updated in cases where the DAC state would not. We fix both of
   these problems by moving the security_file_set_fowner() hook into the
   same section of code where the DAC attributes are updated. Not only
   does this resolve the DAC/LSM synchronization issue, but as that code
   block is protected by a lock, it also resolve the race condition.

 - Fix potential problems with the security_inode_free() LSM hook

   Due to use of RCU to protect inodes and the placement of the LSM hook
   associated with freeing the inode, there is a bit of a challenge when
   it comes to managing any LSM state associated with an inode. The VFS
   folks are not open to relocating the LSM hook so we have to get
   creative when it comes to releasing an inode's LSM state.
   Traditionally we have used a single LSM callback within the hook that
   is triggered when the inode is "marked for death", but not actually
   released due to RCU.

   Unfortunately, this causes problems for LSMs which want to take an
   action when the inode's associated LSM state is actually released; so
   we add an additional LSM callback, inode_free_security_rcu(), that is
   called when the inode's LSM state is released in the RCU free
   callback.

 - Refactor two LSM hooks to better fit the LSM return value patterns

   The vast majority of the LSM hooks follow the "return 0 on success,
   negative values on failure" pattern, however, there are a small
   handful that have unique return value behaviors which has caused
   confusion in the past and makes it difficult for the BPF verifier to
   properly vet BPF LSM programs. This includes patches to
   convert two of these"special" LSM hooks to the common 0/-ERRNO pattern.

 - Various cleanups and improvements

   A handful of patches to remove redundant code, better leverage the
   IS_ERR_OR_NULL() helper, add missing "static" markings, and do some
   minor style fixups.

Merge tag 'vfs-6.12.misc' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Pull misc vfs updates from Christian Brauner:
 "This contains the usual pile of misc updates:

  Features:

   - Add F_CREATED_QUERY fcntl() that allows userspace to query whether
     a file was actually created. Often userspace wants to know whether
     an O_CREATE request did actually create a file without using
     O_EXCL. The current logic is that to first attempts to open the
     file without O_CREAT | O_EXCL and if ENOENT is returned userspace
     tries again with both flags. If that succeeds all is well. If it
     now reports EEXIST it retries.

     That works fairly well but some corner cases make this more
     involved. If this operates on a dangling symlink the first openat()
     without O_CREAT | O_EXCL will return ENOENT but the second openat()
     with O_CREAT | O_EXCL will fail with EEXIST.

     The reason is that openat() without O_CREAT | O_EXCL follows the
     symlink while O_CREAT | O_EXCL doesn't for security reasons. So
     it's not something we can really change unless we add an explicit
     opt-in via O_FOLLOW which seems really ugly.

     All available workarounds are really nasty (fanotify, bpf lsm etc)
     so add a simple fcntl().

   - Try an opportunistic lookup for O_CREAT. Today, when opening a file
     we'll typically do a fast lookup, but if O_CREAT is set, the kernel
     always takes the exclusive inode lock. This was likely done with
     the expectation that O_CREAT means that we always expect to do the
     create, but that's often not the case. Many programs set O_CREAT
     even in scenarios where the file already exists (see related
     F_CREATED_QUERY patch motivation above).

     The series contained in the pr rearranges the pathwalk-for-open
     code to also attempt a fast_lookup in certain O_CREAT cases. If a
     positive dentry is found, the inode_lock can be avoided altogether
     and it can stay in rcuwalk mode for the last step_into.

   - Expose the 64 bit mount id via name_to_handle_at()

     Now that we provide a unique 64-bit mount ID interface in statx(2),
     we can now provide a race-free way for name_to_handle_at(2) to
     provide a file handle and corresponding mount without needing to
     worry about racing with /proc/mountinfo parsing or having to open a
     file just to do statx(2).

     While this is not necessary if you are using AT_EMPTY_PATH and
     don't care about an extra statx(2) call, users that pass full paths
     into name_to_handle_at(2) need to know which mount the file handle
     comes from (to make sure they don't try to open_by_handle_at a file
     handle from a different filesystem) and switching to AT_EMPTY_PATH
     would require allocating a file for every name_to_handle_at(2) call

   - Add a per dentry expire timeout to autofs

     There are two fairly well known automounter map formats, the autofs
     format and the amd format (more or less System V and Berkley).

     Some time ago Linux autofs added an amd map format parser that
     implemented a fair amount of the amd functionality. This was done
     within the autofs infrastructure and some functionality wasn't
     implemented because it either didn't make sense or required extra
     kernel changes. The idea was to restrict changes to be within the
     existing autofs functionality as much as possible and leave changes
     with a wider scope to be considered later.

     One of these changes is implementing the amd options:
      1) "unmount", expire this mount according to a timeout (same as
         the current autofs default).
      2) "nounmount", don't expire this mount (same as setting the
         autofs timeout to 0 except only for this specific mount) .
      3) "utimeout=<seconds>", expire this mount using the specified
         timeout (again same as setting the autofs timeout but only for
         this mount)

     To implement these options per-dentry expire timeouts need to be
     implemented for autofs indirect mounts. This is because all map
     keys (mounts) for autofs indirect mounts use an expire timeout
     stored in the autofs mount super block info. structure and all
     indirect mounts use the same expire timeout.

  Fixes:

   - Fix missing fput for FSCONFIG_SET_FD in autofs

   - Use param->file for FSCONFIG_SET_FD in coda

   - Delete the 'fs/netfs' proc subtreee when netfs module exits

   - Make sure that struct uid_gid_map fits into a single cacheline

   - Don't flush in-flight wb switches for superblocks without cgroup
     writeback

   - Correcting the idmapping mount example in the idmapping
     documentation

   - Fix a race between evice_inodes() and find_inode() and iput()

   - Refine the show_inode_state() macro definition in writeback code

   - Prevent dump_mapping() from accessing invalid dentry.d_name.name

   - Show actual source for debugfs in /proc/mounts

   - Annotate data-race of busy_poll_usecs in eventpoll

   - Don't WARN for racy path_noexec check in exec code

   - Handle OOM on mnt_warn_timestamp_expiry()

   - Fix some spelling in the iomap design documentation

   - Fix typo in procfs comment

   - Fix typo in fs/namespace.c comment

  Cleanups:

   - Add the VFS git tree to the MAINTAINERS file

   - Move FMODE_UNSIGNED_OFFSET to fop_flags freeing up another f_mode
     bit in struct file bringing us to 5 free f_mode bits

   - Remove the __I_DIO_WAKEUP bit from i_state flags as we can simplify
     the wait mechanism

   - Remove the unused path_put_init() helper

   - Replace a __u32 with u32 for s_fsnotify_mask as __u32 is uapi
     specific

   - Replace the unsigned long i_state member with a u32 i_state member
     in struct inode freeing up 4 bytes in struct inode. Instead of
     using the bit based wait apis we're now using the var event apis
     and using the individual bytes of the i_state member to wait on
     state changes

   - Explain how per-syscall AT_* flags should be allocated

   - Use in_group_or_capable() helper to simplify the posix acl mode
     update code

   - Switch to LIST_HEAD() in fsync_buffers_list() to simplify the code

   - Removed comment about d_rcu_to_refcount() as that function doesn't
     exist anymore

   - Add kernel documentation for lookup_fast()

   - Don't re-zero evenpoll fields

   - Remove outdated comment after close_fd()

   - Fix imprecise wording in comment about the pipe filesystem

   - Drop GFP_NOFAIL mode from alloc_page_buffers

   - Missing blank line warnings and struct declaration improved in
     file_table

   - Annotate struct poll_list with __counted_by()

   - Remove the unused read parameter in percpu-rwsem

   - Remove linux/prefetch.h include from direct-io code

   - Use kmemdup_array instead of kmemdup for multiple allocation in
     mnt_idmapping code

   - Remove unused mnt_cursor_del() declaration

  Performance tweaks:

   - Dodge smp_mb in break_lease and break_deleg in the common case

   - Only read fops once in fops_{get,put}()

   - Use RCU in ilookup()

   - Elide smp_mb in iversion handling in the common case

   - Drop one lock trip in evict()"

Pull power management updates from Rafael Wysocki:
 "By the number of new lines of code, the most visible change here is
  the addition of hybrid CPU capacity scaling support to the
  intel_pstate driver. Next are the amd-pstate driver changes related to
  the calculation of the AMD boost numerator and preferred core
  detection.

  As far as new hardware support is concerned, the intel_idle driver
  will now handle Granite Rapids Xeon processors natively, the
  intel_rapl power capping driver will recognize family 1Ah of AMD
  processors and Intel ArrowLake-U chipos, and intel_pstate will handle
  Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode.

  Apart from the above, there is a usual collection of assorted fixes
  and code cleanups in many places and there are tooling updates.

Linus Torvalds
9410645520 Networking changes for 6.12. 
The zero-copy changes are relatively significant, but regression risk
 should be contained. The feature needs to be used to cause trouble.
 The new code did trigger a PowerPC64 bug with GCC 14:
 
   https://lore.kernel.org/netdev/20240913125302.0a06b4c7@canb.auug.org.au/
 
 a fix for which Michael will bring via his tree:
 
   https://lore.kernel.org/all/87jzffq9ge.fsf@mail.lhotse/
 
 Unideal, not sure if you'll be willing to pull without that fix but
 since we caught this recently I figured we'll defer to you during
 the MW instead of trying to fix it cross-tree.
 
 Also it feels like we got an order of magnitude more semi-automated
 "refactoring" chaff than usual, I wonder if it's just us.
 
 Core & protocols
 ----------------
 
  - Support Device Memory TCP, ability to zero-copy receive TCP payloads
    to a DMABUF region of memory while packet headers land separately
    in normal kernel buffers, and TCP processes then as usual.
 
  - The ability to read the PTP PHC (Physical Hardware Clock) alongside
    MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously
    only CLOCK_REALTIME was supported.
 
  - Allow matching on all bits of IP DSCP for routing decisions.
    Previously we only supported on matching TOS bits in IPv4 which
    is a narrower interpretation of the same header field.
 
  - Increase the range of weights used for multi-path routing from
    8 bits to 16 bits.
 
  - Add support for IPv6 PIO p flag in the Prefix Information Option
    per draft-ietf-6man-pio-pflag.
 
  - IPv6 IOAM6 support for new tunsrc encap mode for better performance.
 
  - Detect destinations which blackhole MPTCP traffic and avoid initiating
    MPTCP connections to them for a certain period of time, 1h by default.
 
  - Improve IPsec control path performance by removing the inexact
    policies list.
 
  - AF_VSOCK: add support for SIOCOUTQ ioctl.
 
  - Add enum for reasons TCP reset was sent for easier tracing.
 
  - Add SMC ringbufs usage statistics.
 
 Drivers
 -------
 
  - Handle netconsole setup failures more gracefully, don't fail loading,
    retain the specified target as disabled.
 
  - Extend bonding's IPsec offload pass thru capabilities (ESN, stats).
 
 Filtering
 ---------
 
  - Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
    when long-lived sockets miss a chance to set additional callbacks
    if a sockops program was not attached early in their lifetime.
 
  - Support using BPF skb helpers in tracepoints.
 
  - Conntrack Netlink: support CTA_FILTER for flush.
 
  - Improve SCTP support in nfnetlink_queue.
 
  - Improve performance of large nftables flush transactions.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - selftests: support setting an "interpreter" for script files;
    make it easy to run as separate cases tests where one "interpreter"
    is fed various test descriptions (in our case packet sequences).
 
 Driver API
 ----------
 
  - Extend core and ethtool APIs to support many PHYs connected to a single
    interface (PHY topologies).
 
  - Extend cable diagnostics to specify whether Time Domain Reflectometry
    (TDR) or Active Link Cable Diagnostic (ALCD) was used.
 
  - Add library for implementing MAC-PHY Ethernet drivers for SPI devices
    compatible with Open Alliance 10BASE-T1x MAC-PHY Serial Interface (TC6)
    standard.
 
  - Add helpers to the PHY framework, for PHYs following the Open Alliance
    standards:
    - 1000BaseT1 link settings
    - cable test and diagnostics
 
  - Support listing / dumping all allocated RSS contexts.
 
  - Add configuration for frequency Embedded SYNC in DPLL, which magically
    embeds sync pulses into Ethernet signaling.

   - Add enum for reasons TCP reset was sent for easier tracing.

   - Add SMC ringbufs usage statistics.

  Drivers:

   - Handle netconsole setup failures more gracefully, don't fail
     loading, retain the specified target as disabled.

   - Extend bonding's IPsec offload pass thru capabilities (ESN, stats).

  Filtering:

   - Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
     when long-lived sockets miss a chance to set additional callbacks
     if a sockops program was not attached early in their lifetime.

   - Support using BPF skb helpers in tracepoints.

   - Conntrack Netlink: support CTA_FILTER for flush.

   - Improve SCTP support in nfnetlink_queue.

   - Improve performance of large nftables flush transactions.

  Things we sprinkled into general kernel code:

   - selftests: support setting an "interpreter" for script files; make
     it easy to run as separate cases tests where one "interpreter" is
     fed various test descriptions (in our case packet sequences).

  Driver API:

   - Extend core and ethtool APIs to support many PHYs connected to a
     single interface (PHY topologies).

   - Extend cable diagnostics to specify whether Time Domain
     Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was
     used.

   - Add library for implementing MAC-PHY Ethernet drivers for SPI
     devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial
     Interface (TC6) standard.

   - Add helpers to the PHY framework, for PHYs following the Open
     Alliance standards:
       - 1000BaseT1 link settings
       - cable test and diagnostics

   - Support listing / dumping all allocated RSS contexts.

PCI: qcom: Add equalization settings for 16.0 GT/s 
During high data transmission rates such as 16.0 GT/s, there is an
increased risk of signal loss due to poor channel quality and
interference. This can impact receiver's ability to capture signals
accurately.

Hence, as signal compensation is achieved through appropriate lane
equalization, apply lane equalization settings at both transmitter
and receiver which results in an increase in the PCIe signal strength.

While at it, modify the pcie-tegra194 driver to make use of the
common GEN3_EQ_CONTROL_OFF definitions in pcie-designware.h.

ac49b950be dt-bindings: net: add Microchip's LAN865X 10BASE-T1S MACPHY 
The LAN8650/1 combines a Media Access Controller (MAC) and an Ethernet
PHY to enable 10BASE-T1S networks. The Ethernet Media Access Controller
(MAC) module implements a 10 Mbps half duplex Ethernet MAC, compatible
with the IEEE 802.3 standard and a 10BASE-T1S physical layer transceiver
integrated into the LAN8650/1. The communication between the Host and the
MAC-PHY is specified in the OPEN Alliance 10BASE-T1x MACPHY Serial
Interface (TC6).

5cd2340cb6 microchip: lan865x: add driver support for Microchip's LAN865X MAC-PHY 
The LAN8650/1 is designed to conform to the OPEN Alliance 10BASE-T1x
MAC-PHY Serial Interface specification, Version 1.1. The IEEE Clause 4
MAC integration provides the low pin count standard SPI interface to any
microcontroller therefore providing Ethernet functionality without
requiring MAC integration within the microcontroller. The LAN8650/1
operates as an SPI client supporting SCLK clock rates up to a maximum of
25 MHz. This SPI interface supports the transfer of both data (Ethernet
frames) and control (register access).

By default, the chunk data payload is 64 bytes in size. The Ethernet
Media Access Controller (MAC) module implements a 10 Mbps half duplex
Ethernet MAC, compatible with the IEEE 802.3 standard. 10BASE-T1S
physical layer transceiver integrated is into the LAN8650/1. The PHY and
MAC are connected via an internal Media Independent Interface (MII).

aa58bec064 net: ethernet: oa_tc6: implement register write operation 
Implement register write operation according to the control communication
specified in the OPEN Alliance 10BASE-T1x MACPHY Serial Interface
document. Control write commands are used by the SPI host to write
registers within the MAC-PHY. Each control write commands are composed of
a 32 bits control command header followed by register write data.

The MAC-PHY ignores the final 32 bits of data from the SPI host at the
end of the control write command. The write command and data is also
echoed from the MAC-PHY back to the SPI host to enable the SPI host to
identify which register write failed in the case of any bus errors.
Control write commands can write either a single register or multiple
consecutive registers. When multiple consecutive registers are written,
the address is automatically post-incremented by the MAC-PHY. Writing to
any unimplemented or undefined registers shall be ignored and yield no
effect.

b3e33f2c54 Documentation: networking: add OPEN Alliance 10BASE-T1x MAC-PHY serial interface 
The IEEE 802.3cg project defines two 10 Mbit/s PHYs operating over a
single pair of conductors. The 10BASE-T1L (Clause 146) is a long reach
PHY supporting full duplex point-to-point operation over 1 km of single
balanced pair of conductors. The 10BASE-T1S (Clause 147) is a short reach
PHY supporting full / half duplex point-to-point operation over 15 m of
single balanced pair of conductors, or half duplex multidrop bus
operation over 25 m of single balanced pair of conductors.

Furthermore, the IEEE 802.3cg project defines the new Physical Layer
Collision Avoidance (PLCA) Reconciliation Sublayer (Clause 148) meant to
provide improved determinism to the CSMA/CD media access method. PLCA
works in conjunction with the 10BASE-T1S PHY operating in multidrop mode.

The aforementioned PHYs are intended to cover the low-speed / low-cost
applications in industrial and automotive environment. The large number
of pins (16) required by the MII interface, which is specified by the
IEEE 802.3 in Clause 22, is one of the major cost factors that need to be
addressed to fulfil this objective.

The MAC-PHY solution integrates an IEEE Clause 4 MAC and a 10BASE-T1x PHY
exposing a low pin count Serial Peripheral Interface (SPI) to the host
microcontroller. This also enables the addition of Ethernet functionality
to existing low-end microcontrollers which do not integrate a MAC
controller.

5f15811286 nvmem: layouts: add U-Boot env layout 
U-Boot environment variables are stored in a specific format. Actual
data can be placed in various storage sources (MTD, UBI volume, EEPROM,
NVRAM, etc.).

Move all generic (NVMEM device independent) code from NVMEM device
driver to an NVMEM layout driver. Then add a simple NVMEM layout code on
top of it.

This allows using NVMEM layout for parsing U-Boot env data stored in any
kind of NVMEM device.

The old NVMEM glue driver stays in place for handling bindings in the
MTD context. To avoid code duplication it uses exported layout parsing
function. Please note that handling MTD & NVMEM layout bindings may be
refactored in the future.

f55d3b82ac MAINTAINERS: Move the BFQ io scheduler to Odd Fixes state 
BFQ has been lacking active maintenance for approximately two years, and it
was recently transitioned to the Orphan state. However, there are still
many users, I have decided to step forward and assume the role of
maintainer to ensure continued support and development.

While I may not be the one with the most extensive knowledge of BFQ's
internals, I have been actively involved in its development since 2021.
Moreover, our team continues to rigorously test BFQ in downstream kernels,
ensuring it's stability and performance. Despite my confidence to maintain
BFQ, I believe it is prudent to classify its state as "Odd Fixes" to
accurately reflect my relatively new position as the maintainer.

By assuming this responsibility, I am committed to providing the necessary
support and addressing any issues that may arise with BFQ. As time
progresses, we will reassess the situation and determine the appropriate
state.

6c5b3e30e5 Rust fixes for v6.11 (2nd) 
Toolchain and infrastructure:
 
  - Fix builds for nightly compiler users now that 'new_uninit' was split
    into new features by using an alternative approach for the code that
    used what is now called the 'box_uninit_write' feature.
 
  - Allow the 'stable_features' lint to preempt upcoming warnings about
    them, since soon there will be unstable features that will become
    stable in nightly compilers.
 
  - Export bss symbols too.
 
 'kernel' crate:
 
  - 'block' module: fix wrong usage of lockdep API.
 
 'macros' crate:
 
  - Provide correct provenance when constructing 'THIS_MODULE'.
 
 Documentation:
 
  - Remove unintended indentation (blockquotes) in generated output.
 
  - Fix a couple typos.
 
 MAINTAINERS:
 
  - Remove Wedson as Rust maintainer.
 
  - Update Andreas' email.

Pull Rust fixes from Miguel Ojeda:
 "Toolchain and infrastructure:

   - Fix builds for nightly compiler users now that 'new_uninit' was
     split into new features by using an alternative approach for the
     code that used what is now called the 'box_uninit_write' feature

   - Allow the 'stable_features' lint to preempt upcoming warnings about
     them, since soon there will be unstable features that will become
     stable in nightly compilers

   - Export bss symbols too

  'kernel' crate:

   - 'block' module: fix wrong usage of lockdep API

  'macros' crate:

   - Provide correct provenance when constructing 'THIS_MODULE'

  Documentation:

   - Remove unintended indentation (blockquotes) in generated output

   - Fix a couple typos

  MAINTAINERS:

   - Remove Wedson as Rust maintainer

   - Update Andreas' email"

depending on the model).

It also exports the EDID from the outputs and allows reading and
setting the EDID of the input.

 The QSEECOM uefisecapp interface is allow-listed on Surface Laptop 7 and
 Lenovo Thinkpad T14s, providing EFI variable access.
 
 The change to match the SMD RPM driver based on the SMD channel name is
 reverted, in favor of stepping back to OF-based matching, as a means to
 get module autoloading to work properly.
 
 AOSS, APR, ICE, OCMEM, PBS and SMP2P drivers has error handling cleaned
 up using scoped resources.
 
 Trace events are added to the BWMON and SMP2P drivers, for better
 insights into their operations.

ff60bfbaf6 can: rockchip_canfd: add driver for Rockchip CAN-FD controller 
Add driver for the Rockchip CAN-FD controller.

The IP core on the rk3568v2 SoC has 12 documented errata. Corrections
for these errata will be added in the upcoming patches.

Since several workarounds are required for the TX path, only add the
base driver that only implements the RX path.

Although the RX path implements CAN-FD support, it's not activated in
ctrlmode_supported, as the IP core in the rk3568v2 has problems with
receiving or sending certain CAN-FD frames.

68d3b6aa08 MAINTAINERS: add Trevor Gross as Rust reviewer 
Trevor has been involved with the Rust for Linux project for more than
a year now. He has been active reviewing Rust code in the mailing list,
and he already is a formal reviewer of the Rust PHY library and the two
PHY drivers.

In addition, he is also part of several upstream Rust teams:
compiler-contributors team (contributors to the Rust compiler on a regular
basis), libs-contributors (contributors to the Rust standard library on a
regular basis), crate-maintainers (maintainers of official Rust crates),
the binary size working group and the Rust for Linux ping group.

His expertise with the language will be very useful to have around in
the future if Rust keeps growing within the kernel, thus add him to the
`RUST` entry as a reviewer.

f53835f110 IIO: 1st set of new device support, features and cleanup for 6.12 
Includes a merge of spi-mos-config branch from spi.git that brings
 support needed for the AD4000 driver.
 
 Lots of new device support this time including 9 new drivers and substantial
 changes to add new support to several more.
 
 New device support
 ------------------
 
 Given we have a lot of new support, I've subcategorized them:
 
 Substantial changes, or new driver
 **********************************
 
 adi,ad4000
 - New driver for this high speed ADC.
 adi,ad4695
 - New driver supporting AD4690, AD4696, AD4697 and AD4698 ADCs.
 - Follow up series added triggered buffer support.
 adi,ad7380
 - Add support for single ended parts, AD7386, ADC7387, AD7388 and -4 variants.
   (driver previously only support differential parts).
   These variants have an additional front end MUX so only half the channels
   can be sampled efficiently.
 adi,ad9467
 - Refactor and extend driver to support ad9643, ad9449 and ad9652 high speed
   ADCs.
 adi,adxl380
 - New driver for this low power accelerometer.
 adi,ltc2664
 - New driver supporting LTC2664 and LTC2672 DACs.
 microchip,pac1921
 - New driver for this power/current monitor chip.
 rohm,bh1745
 - New driver for this RGBC colour sensor.
 rohm,bu27034anuc
 - The original bu27034 was canceled before mass production, so the
   driver is modified to support the BU27034ANUC which had some significant
   differences.  DT compatible changed to avoid chance of old driver ever
   binding to real hardware.
 sciosense,ens210
 - New driver for ens210, ens210a, ens211, ens212, ens213a, and ens215
   temperature and humidity sensors (all register compatible up to some
   conversion time differences)
 sensiron,sdp500
 - New driver for this differential pressure sensor.
 tyhx,hx9023s
 - New driver to support this capacitive proximity sensor.
 
 Minor changes to support new devices
 ************************************
 
 adi,adf4377
 - Add support for the single output adf4378.
 kionix,kxcjk-1013
 - Add support for KX022-1020 accelerometer (binding and ID table only)
 liteon,ltrf216a
 - Add support for ltr-308.  A few minor differences in features set
 rockchip,saradc
 - Add ID for rk3576-saradc
 sensortek,stk3310
 - Add ID for stk3013 proximity sensor which (despite documentation) has
   an ambient light sensor and is compatible with existing parts.
 
 Documentation updates
 ---------------------
 
 Generalize ABI docs for shunt resistor attribute
 Improve calibscale and calibbias related documentation.  A couple of follow
 up patches to resolve duplicate documentation that resulted.
 
 New core features
 -----------------
 
 backend
 - Add option for debugfs - useful for test pattern control
 - Use this for both adi-axi-adc and adi-axi-dac
 trigger suspend
 - Add functions to allow triggers to be suspended. This avoids problems
   when a device enters suspend to idle with a sysfs trigger. Use it for now
   in the bmi323 only.
 
 New driver features
 -------------------
 
 adi,ad7192
 - Add option to be a clock provider (+ additional clock config options)
 adi,ad7380
 - Add documentation for this fairly new driver.
 adi,ad9461
 - Provide control of test modes and backend validation blocks used
   to identify problems (via debugfs)
 adi,ad9739
 - Add backend debugfs and docs for what is provided via adi-axi-dac
 avago,apds9960
 - Add proximity and gesture calibration offset control
 bosch,bmp280
 - Triggered buffer support including adding raw+scale output for sysfs.
 liteon,ltr390
 - Add configuration of integration time and scale.
 stm,dfsdm
 - Convert this SD modulator driver to backend framework and add support
   for channel scaling + modern channel bindings.
 
 Treewide cleanup
 ----------------
 
 iio_dev->masklength: Making it private.
 - Provide access function to read the core compute channel mask length
   and a macro to iterate over elements in the active_scan_mask.
 - Enables marking masklength __private preventing drivers from
   writing it without triggering a build warning whilst minimizing overhead
   in what are typically hot paths.
 - Convert all drivers and finally mark it private.
   Merge conflicts resolved in drivers applied after this point.
 Constify regmap_bus
 - These are never modified, so mark them const.
 
 Core cleanup
 ------------
 
 backend
 - A few late breaking bits of feedback (unused variable, error messages)
 dma-buffer
 - Namespace exports.
 core
 - Drop unused assignment.
 
 Driver cleanup
 --------------
 
 adi,ad4695
 - Fixing binding to reflect that common-mode-channel is a scalar.
 adi,ad7280a
 - Use __free(kfree) to simplify freeing of receive buffer.
 adi,ad7606
 - Various dt-binding cleanup and improvements.
 - Fix oversampling related gpio handling.
 - Make polarity of standby gpio match documentation.
 - use guard() to simplify lock handling.
 adi,ad7768
 - Use device_for_each_child_node_scoped() instead of fwnode equivalent.
 adi,ad7124
 - Reduce SPI transfers by avoiding separate writes to different fields
   in the same register.
 - Start the ADC in idle mode.
 adi,adis
 - Drop ifdefs in favor of IS_ENABLED.
 adi,admv8818
 - Fix wrong ABI docs.
 asahi-kasei,ak8975
 - Drop a prefix free compatible accidentally added recently.
 aspeed,adc
 - Use of_property_present() instead of of_find_property() to see if the
   property is there or not.
 atmel,at91,
 - Use __free(kfree) to simplify freeing of channel related array.
 bosch,bma400
 - Use __free(kfree) to simplify freeing a locally allocated string.
 bosch,bmc150
 - Add missing mount-matrix binding docs.
 bosch,bme680
 - Fix read/write to ensure multiple necessary sequential reads without
   device configuration change.
 - Drop unnecessary type casts and use more appropriate data types.
 - Drop some left over ACPI code as ACPI support was removed due to invalid
   IDs (and no known users).
 - Sort headers consistently.
 - Avoid unnecessary duplicate read and redundant read of gas config.
 - Use bulk reads to get calibration data.
 - Reorder allocation of IIO device to be prior to device init.
 - Add remaining read/write buffers to the union used already for all others.
 - Tidy up error checks for consistency of style, including dev_err_probe()
 - Bring the device startup procedure inline with the vendor code.
 - Reorder code so mode forcing is more obvious occurring where needed.
 - Tidy up data locality in reading functions so no magic data is stored
   in state structures just to get it across function calls.
 - Make a local lookup table static to avoid placing it on the stack.
 bosch,bmp280
 - Fix BME280 regmap to not include registers it doesn't have.
 - Wait a little longer after config to allow for maximum possible necessary
   wait.
 - Reorganize headers.
 - Make conversion_time_max array static to avoid placing it on the stack.
 maxim,max1363
 - Use __free(kfree) to simplify freeing transmission buffer.
 microchip,mcp3964
 - Use devm_regulator_get_enable_read_voltage()
 microchip,mcp3911
 - Use devm_regulator_get_enable_read_voltage()
 microchip,mcp4728
 - Use devm_regulator_get_enable_read_voltage()
 microchip,mcp4922
 - Use devm_regulator_get_enable_read_voltage() and devm_* to allow
   dropping of explicit remove() callback.
 onnn,noa1305
 - Various tidy up.
 - Provide available scale values.
 - Make integration time configurable.
 - Fix up integration time look up (/2 error)
 ti,dac7311
 - Check if spi_setup() succeeded.
 ti,tsc2046
 - Use __free(kfree) to simplify freeing rx and tx buffers.
 - Use devm_regulator_get_enable_read_voltage()
 
 Various minor fixes not called out explicitly.

- Add backend debugfs and docs for what is provided via adi-axi-dac
avago,apds9960
- Add proximity and gesture calibration offset control
bosch,bmp280
- Triggered buffer support including adding raw+scale output for sysfs.
liteon,ltr390
- Add configuration of integration time and scale.
stm,dfsdm
- Convert this SD modulator driver to backend framework and add support
  for channel scaling + modern channel bindings.

Treewide cleanup
----------------

iio_dev->masklength: Making it private.
- Provide access function to read the core compute channel mask length
  and a macro to iterate over elements in the active_scan_mask.
- Enables marking masklength __private preventing drivers from
  writing it without triggering a build warning whilst minimizing overhead
  in what are typically hot paths.
- Convert all drivers and finally mark it private.
  Merge conflicts resolved in drivers applied after this point.
Constify regmap_bus
- These are never modified, so mark them const.

Core cleanup
------------

backend
- A few late breaking bits of feedback (unused variable, error messages)
dma-buffer
- Namespace exports.
core
- Drop unused assignment.

Driver cleanup
--------------

adi,ad4695
- Fixing binding to reflect that common-mode-channel is a scalar.
adi,ad7280a

5b9da39dc5 failcmd: add script file in MAINTAINERS 
failcmd is one of the main interfaces to fault injection framework, but,
it is not listed under FAULT INJECTION SUPPORT entry in MAINTAINERS.  This
is unfortunate, since git-send-email doesn't find emails to send the

Akinobu Mita seems to be actively maintaining it, so, let's add the file

22be8e6b13 MAINTAINERS: add XZ Embedded maintainer 
Patch series "xz: Updates to license, filters, and compression options",
v2.

XZ Embedded, the upstream project, switched from public domain to the BSD
Zero Clause License (0BSD).  Now matching SPDX license identifiers can be
added.

Documentation was revised.  Fix syntax errors in kernel-doc comments in
<linux/xz.h>.  The xz_dec API docs from <linux/xz.h> are now included in
Documentation/staging/xz.rst.

The new ARM64 and RISC-V filters can be used for kernel decompression if
CONFIG_EFI_ZBOOT=y.  The filters can be used by Squashfs too.  (Userspace
Squashfs-tools already had the ARM64 filter support committed but it was
reverted due to backdoor fears.  I try to get ARM64 and RISC-V filter
support added to Squashfs-tools somewhat soon.)

Account for the default threading change made in the xz command line tool
version 5.6.0.  Tweak kernel compression options for archs that support XZ
compressed kernel.


This patch (of 16):

I have been the maintainer of the upstream project since I submitted the
code to Linux in 2010 but I forgot to add myself to MAINTAINERS.

9325b8b5a1 tools: add skeleton code for userland testing of VMA logic 
Establish a new userland VMA unit testing implementation under
tools/testing which utilises existing logic providing maple tree support
in userland utilising the now-shared code previously exclusive to radix
tree testing.

This provides fundamental VMA operations whose API is defined in mm/vma.h,
while stubbing out superfluous functionality.

This exists as a proof-of-concept, with the test implementation functional
and sufficient to allow userland compilation of vma.c, but containing only
cursory tests to demonstrate basic functionality.

35667a2969 ARM: SoC fixes for 6.11, part 2 
There is a fairly large number of bug fixes for Qualcomm platforms,
 most of them addressing issues with the devicetree files for the
 newly added Snapdragon X1 based laptops to make them more reliable.
 The Qualcomm driver changes address a few build-time issues as well
 as runtime problems in the tzmem and scm firmware, the USB Type-C
 driver, and the cmd-db and pmic_glink soc drivers.
 
 The NXP i.MX usually gets a bunch of devicetree fixes that is proportional
 to the number of supported machines. This includes both warning fixes
 and correctness for the 64-bit i.MX9, i.MX8 and layerscape platforms,
 as well as a single fix for a 32-bit i.MX6 based board.
 
 The other changes are the usual minor changes, including an update to the
 MAINTAINERS file, an omap3 dts file and a SoC driver for mpfs (risc-v).

  runtime problems in the tzmem and scm firmware, the USB Type-C driver,
  and the cmd-db and pmic_glink soc drivers.

  The NXP i.MX usually gets a bunch of devicetree fixes that is
  proportional to the number of supported machines. This includes both
  warning fixes and correctness for the 64-bit i.MX9, i.MX8 and
  layerscape platforms, as well as a single fix for a 32-bit i.MX6 based
  board.

  The other changes are the usual minor changes, including an update to
  the MAINTAINERS file, an omap3 dts file and a SoC driver for mpfs
  (risc-v)"

switched to use a separate config option, so that the legacy code won't be

918eb5c856 iommu/arm-smmu-v3: Add in-kernel support for NVIDIA Tegra241 (Grace) CMDQV 
NVIDIA's Tegra241 Soc has a CMDQ-Virtualization (CMDQV) hardware, extending
the standard ARM SMMU v3 IP to support multiple VCMDQs with virtualization
capabilities. In terms of command queue, they are very like a standard SMMU
CMDQ (or ECMDQs), but only support CS_NONE in the CS field of CMD_SYNC.

Add a new tegra241-cmdqv driver, and insert its structure pointer into the
existing arm_smmu_device, and then add related function calls in the SMMUv3
driver to interact with the CMDQV driver.

In the CMDQV driver, add a minimal part for the in-kernel support: reserve
VINTF0 for in-kernel use, and assign some of the VCMDQs to the VINTF0, and
select one VCMDQ based on the current CPU ID to execute supported commands.
This multi-queue design for in-kernel use gives some limited improvements:
up to 20% reduction of invalidation time was measured by a multi-threaded
DMA unmap benchmark, compared to a single queue.

The other part of the CMDQV driver will be user-space support that gives a
hypervisor running on the host OS to talk to the driver for virtualization
use cases, allowing VMs to use VCMDQs without trappings, i.e. no VM Exits.
This is designed based on IOMMUFD, and its RFC series is also under review.
It will provide a guest OS a bigger improvement: 70% to 90% reductions of
TLB invalidation time were measured by DMA unmap tests running in a guest,
compared to nested SMMU CMDQ (with trappings).

As the initial version, the CMDQV driver only supports ACPI configurations.

The original driver for TN40xx chips supports multiple PHY hardware
(AMCC QT2025, TI TLK10232, Aqrate AQR105, and Marvell 88X3120,
88X3310, and MV88E2010). This driver is extracted from the original
driver and modified to a PHY driver in Rust.

This has been tested with Edimax EN-9320SFP+ 10G network adapter.

b57d643a67 MAINTAINERS: exclude bluetooth and wireless DT bindings from netdev ML 
We exclude wireless drivers from the netdev@ traffic, to delegate
it to linux-wireless@, and avoid overwhelming netdev@.
Bluetooth drivers are implicitly excluded because they live under
drivers/bluetooth, not drivers/net.

In both cases DT bindings sit under Documentation/devicetree/bindings/net/
and aren't excluded. So if a patch series touches DT bindings
netdev@ ends up getting CCed, and these are usually fairly boring
series.

907fa79d78 MAINTAINERS: scale modules with more reviewers 
We're looking to add Rust module support, and I don't speak
Rust yet. The compromise was reached that in order to scale we'd
get volunteers committed from the Rust community willing to review
both Rust and C code for modules so we can ensure we get proper
reviews for both parts of the code and so that we can scale.

Add those who have stepped up to help.

d8f2638b83 Qualcomm driver fixes for v6.11 
This corrects the tzmem virt-to-phys conversion, which caused issues for
 the uefisecapp implementation of EFI variable access. SDM670 is excluded
 from tzmem usage due to reported issues.
 
 The SCM get wait queue context call is corrected to be marked ATOMIC and
 some dead code in qseecom, following the tzmem conversion, is removed.
 
 The memory backing command DB is remapped writecombined, to avoid XPU
 violations when Linux runs without the Qualcomm hypervisor.
 
 Two compile fixes are added for pd-mapper, and the broken reference
 count is corrected, to make pd-mapper deal with remoteprocs going away.
 
 In pmic_glink a race condition where the client callbacks might be
 called before we returned the client handle is corrected. The broken conditions
 for when to signal that the firmware is going down is also corrected.
 
 In the pmic_glink UCSI driver, the ucsi_unregister() is moved out of the
 pdr callback, as this is being invoked in atomic context.
 
 Konrad's email address is updated in MAINTAINERS, and related mailmap
 entries are added.

73d5fc92a1 dmaengine: amd: qdma: Add AMD QDMA driver 
Adds driver to enable PCIe board which uses AMD QDMA (the Queue-based
Direct Memory Access) subsystem. For example, Xilinx Alveo V70 AI
Accelerator devices.
    https://www.xilinx.com/applications/data-center/v70.html

The QDMA subsystem is used in conjunction with the PCI Express IP block
to provide high performance data transfer between host memory and the
card's DMA subsystem.

            +-------+       +-------+       +-----------+
   PCIe     |       |       |       |       |           |
   Tx/Rx    |       |       |       |  AXI  |           |
 <=======>  | PCIE  | <===> | QDMA  | <====>| User Logic|
            |       |       |       |       |           |
            +-------+       +-------+       +-----------+

The primary mechanism to transfer data using the QDMA is for the QDMA
engine to operate on instructions (descriptors) provided by the host
operating system. Using the descriptors, the QDMA can move data in both
the Host to Card (H2C) direction, or the Card to Host (C2H) direction.
The QDMA provides a per-queue basis option whether DMA traffic goes
to an AXI4 memory map (MM) interface or to an AXI4-Stream interface.

The hardware detail is provided by
    https://docs.xilinx.com/r/en-US/pg302-qdma

Implements dmaengine APIs to support MM DMA transfers.
- probe the available DMA channels
- use dma_slave_map for channel lookup
- use virtual channel to manage dmaengine tx descriptors
- implement device_prep_slave_sg callback to handle host scatter gather

Some of the newer Microsoft Surface devices (such as the Surface Book
3 and Pro 9) have thermal sensors connected via the Surface Aggregator
Module (the embedded controller on those devices). Add a basic driver
to read out the temperature values of those sensors.

The EC can have up to 16 thermal sensors connected via a single
sub-device, each providing temperature readings and a label string.

cbbdb6c625 docs: bug-bisect: rewrite to better match the other bisecting text 
Rewrite the short document on bisecting kernel bugs. The new text
improves .config handling, brings a mention of 'git bisect skip', and
explains what to do after the bisection finished -- including trying a
revert to verify the result. The rewrite at the same time removes the
unrelated and outdated section on 'Devices not appearing' and replaces
some sentences about bug reporting with a pointer to the document
covering that topic in detail.

This overall brings the approach close to the one in the recently added
text Documentation/admin-guide/verify-bugs-and-bisect-regressions.rst.
As those two texts serve a similar purpose for different audiences,
mention that document in the head of this one and outline when the
other might be the better one to follow.

f0c8431568 optee: probe RPMB device using RPMB subsystem 
Adds support in the OP-TEE drivers (both SMC and FF-A ABIs) to probe and
use an RPMB device via the RPMB subsystem instead of passing the RPMB
frames via tee-supplicant in user space. A fallback mechanism is kept to
route RPMB frames via tee-supplicant if the RPMB subsystem isn't
available.

The OP-TEE RPC ABI is extended to support iterating over all RPMB
devices until one is found with the expected RPMB key already
programmed.

1e9046e3a1 rpmb: add Replay Protected Memory Block (RPMB) subsystem 
A number of storage technologies support a specialised hardware
partition designed to be resistant to replay attacks. The underlying
HW protocols differ but the operations are common. The RPMB partition
cannot be accessed via standard block layer, but by a set of specific
RPMB commands. Such a partition provides authenticated and replay
protected access, hence suitable as a secure storage.

The initial aim of this patch is to provide a simple RPMB driver
interface which can be accessed by the optee driver to facilitate early
RPMB access to OP-TEE OS (secure OS) during the boot time.

A TEE device driver can claim the RPMB interface, for example, via
rpmb_interface_register() or rpmb_dev_find_device(). The RPMB driver
provides a callback to route RPMB frames to the RPMB device accessible
via rpmb_route_frames().

The detailed operation of implementing the access is left to the TEE
device driver itself.

The important core fix is another tweak to our discard discovery

 the inline was only ever used in debug prints, which is why no-one

3849687869 net: phy: Introduce ethernet link topology representation 
Link topologies containing multiple network PHYs attached to the same
net_device can be found when using a PHY as a media converter for use
with an SFP connector, on which an SFP transceiver containing a PHY can
be used.

With the current model, the transceiver's PHY can't be used for
operations such as cable testing, timestamping, macsec offload, etc.

The reason being that most of the logic for these configuration, coming
from either ethtool netlink or ioctls tend to use netdev->phydev, which
in multi-phy systems will reference the PHY closest to the MAC.

Introduce a numbering scheme allowing to enumerate PHY devices that
belong to any netdev, which can in turn allow userspace to take more
precise decisions with regard to each PHY's configuration.

The numbering is maintained per-netdev, in a phy_device_list.
The numbering works similarly to a netdevice's ifindex, with
identifiers that are only recycled once INT_MAX has been reached.

This prevents races that could occur between PHY listing and SFP
transceiver removal/insertion.

The identifiers are assigned at phy_attach time, as the numbering
depends on the netdevice the phy is attached to. The PHY index can be
re-used for PHYs that are persistent.

46097a9266 MAINTAINERS: Mark JME Network Driver as Odd Fixes 
This driver only appears to have received sporadic clean-ups, typically
part of some tree-wide activity, and fixes for quite some time.  And
according to the maintainer, Guo-Fu Tseng, the device has been EOLed for
a long time (see Link).

Accordingly, it seems appropriate to mark this driver as odd fixes.

8cb0a938d9 MAINTAINERS: Add limited globs for Networking headers 
This aims to add limited globs to improve the coverage of header files
in the NETWORKING DRIVERS and NETWORKING [GENERAL] sections.

It is done so in a minimal way to exclude overlap with other sections.
And so as not to require "X" entries to exclude files otherwise
matched by these new globs.

While imperfect, due to it's limited nature, this does extend coverage
of header files by these sections. And aims to automatically cover
new files that seem very likely belong to these sections.

The include/linux/netdev* glob (both sections)
+ Subsumes the entries for:
  - include/linux/netdevice.h
+ Extends the sections to cover
  - include/linux/netdevice_xmit.h
  - include/linux/netdev_features.h

The include/uapi/linux/netdev* globs: (both sections)
+ Subsumes the entries for:
  - include/linux/netdevice.h
+ Extends the sections to cover
  - include/linux/netdev.h

The include/linux/skbuff* glob (NETWORKING [GENERAL] section only):
+ Subsumes the entry for:
  - include/linux/skbuff.h
+ Extends the section to cover
  - include/linux/skbuff_ref.h

A include/uapi/linux/net_* glob was not added to the NETWORKING [GENERAL]
section. Although it would subsume the entry for
include/uapi/linux/net_namespace.h, which is fine, it would also extend
coverage to:
- include/uapi/linux/net_dropmon.h, which belongs to the
   NETWORK DROP MONITOR section
- include/uapi/linux/net_tstamp.h which, as per an earlier patch in this
  series, belongs to the SOCKET TIMESTAMPING section
