db0a155040 MAINTAINERS: add drbd co-maintainer 
In light of the recent controversy surrounding the (lack of)
maintenance of the in-tree DRBD driver, we have decided to add myself
as co-maintainer. This allows us to better distribute the workload and
reduce the chance of patches getting lost.

I will be keeping an eye on the mailing list in order to ensure that all
patches get the attention they need.

RISC-V CPU Idle Support 
This series adds RISC-V CPU Idle support using SBI HSM suspend function.
The RISC-V SBI CPU idle driver added by this series is highly inspired
from the ARM PSCI CPU idle driver.

Special thanks Sandeep Tripathy for providing early feeback on SBI HSM
support in all above projects (RISC-V SBI specification, OpenSBI, and
Linux RISC-V).

* palmer/riscv-idle:
  RISC-V: Enable RISC-V SBI CPU Idle driver for QEMU virt machine
  dt-bindings: Add common bindings for ARM and RISC-V idle states
  cpuidle: Add RISC-V SBI CPU idle driver
  cpuidle: Factor-out power domain related code from PSCI domain driver
  RISC-V: Add SBI HSM suspend related defines
  RISC-V: Add arch functions for non-retentive suspend entry/exit
  RISC-V: Rename relocate() and make it global
  RISC-V: Enable CPU_IDLE drivers

9512433987 There's one large change in the core clk framework here. We change how 
clk_set_rate_range() works so that the frequency is re-evaulated each time the
 rate is changed. Previously we wouldn't let clk providers see a rate that was
 different if it was still within the range, which could be bad for power if the
 clk could run slower when a range expands. Now the clk provider can decide to
 do something differently when the constraints change. This broke Nvidia's clk
 driver so we had to wait for the fix for that to bake a little more in -next.
 
 The rate range patch series also introduced a kunit suite for the clk framework
 that we're going to extend in the next release. It already made it easy to find
 corner cases in the rate range patches so I'm excited to see it cover more clk
 code and increase our confidence in core framework patches in the future. I
 also added a kunit test for the basic clk gate code and that work will continue
 to cover more basic clk types: muxes, dividers, etc.
 
 Beyond the core code we have the usual set of clk driver updates and additions.
 Qualcomm again dominates the diffstat here with lots more SoCs being supported
 and i.MX follows afer that with a similar number of SoCs gaining clk drivers.
 Beyond those large additions there's drivers being modernized to use
 clk_parent_data so we can move away from global string names for all the clks
 in an SoC. Finally there's lots of little fixes all over the clk drivers for
 typos, warnings, and missing clks that aren't critical and get batched up
 waiting for the next merge window to open. Nothing super big stands out in the
 driver pile. Full details are below.
 
 Core:
  - Make clk_set_rate_range() re-evaluate the limits each time
  - Introduce various clk_set_rate_range() tests
  - Add clk_drop_range() to drop a previously set range
 
 New Drivers:
  - i.MXRT1050 clock driver and bindings
  - i.MX8DXL clock driver and bindings
  - i.MX93 clock driver and bindings
  - NCO blocks on Apple SoCs
  - Audio clks on StarFive JH7100 RISC-V SoC
  - Add support for the new Renesas RZ/V2L SoC
  - Qualcomm SDX65 A7 PLL
  - Qualcomm SM6350 GPU clks
  - Qualcomm SM6125, SM6350, QCS2290 display clks
  - Qualcomm MSM8226 multimedia clks
 
 Updates:
  - Kunit tests for clk-gate implementation
  - Terminate arrays with sentinels and make that clearer
  - Cleanup SPDX tags
  - Fix typos in comments
  - Mark mux table as const in clk-mux
  - Make the all_lists array const
  - Convert Cirrus Logic CS2000P driver to regmap, yamlify DT binding and add
    support for dynamic mode
  - Clock configuration on Microchip PolarFire SoCs
  - Free allocations on probe error in Mediatek clk driver
  - Modernize Mediatek clk driver by consolidating code
  - Add watchdog (WDT), I2C, and pin function controller (PFC) clocks on
    Renesas R-Car S4-8
  - Improve the clocks for the Rockchip rk3568 display outputs (parenting, pll-rates)
  - Use of_device_get_match_data() instead of open-coding on Rockchip rk3568
  - Reintroduce the expected fractional-divider behaviour that disappeared
    with the addition of CLK_FRAC_DIVIDER_POWER_OF_TWO_PS
  - Remove SYS PLL 1/2 clock gates for i.MX8M*
  - Remove AUDIO MCLK ROOT from i.MX7D
  - Add fracn gppll clock type used by i.MX93
  - Add new composite clock for i.MX93
  - Add missing media mipi phy ref clock for i.MX8MP
  - Fix off by one in imx_lpcg_parse_clks_from_dt()
  - Rework for the imx pll14xx
  - sama7g5: One low priority fix for GCLK of PDMC
  - Add DMA engine (SYS-DMAC) clocks on Renesas R-Car S4-8
  - Add MOST (MediaLB I/F) clocks on Renesas R-Car E3 and D3
  - Add CAN-FD clocks on Renesas R-Car V3U
  - Qualcomm SC8280XP RPMCC
  - Add some missing clks on Qualcomm MSM8992/MSM8994/MSM8998 SoCs
  - Rework Qualcomm GCC bindings and convert SDM845 camera bindig to YAML

1930a6e739 ptrace: Cleanups for v5.18 
This set of changes removes tracehook.h, moves modification of all of
 the ptrace fields inside of siglock to remove races, adds a missing
 permission check to ptrace.c
 
 The removal of tracehook.h is quite significant as it has been a major
 source of confusion in recent years.  Much of that confusion was
 around task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled
 making the semantics clearer).
 
 For people who don't know tracehook.h is a vestiage of an attempt to
 implement uprobes like functionality that was never fully merged, and
 was later superseeded by uprobes when uprobes was merged.  For many
 years now we have been removing what tracehook functionaly a little
 bit at a time.  To the point where now anything left in tracehook.h is
 some weird strange thing that is difficult to understand.
 
 Eric W. Biederman (15):
       ptrace: Move ptrace_report_syscall into ptrace.h
       ptrace/arm: Rename tracehook_report_syscall report_syscall
       ptrace: Create ptrace_report_syscall_{entry,exit} in ptrace.h
       ptrace: Remove arch_syscall_{enter,exit}_tracehook
       ptrace: Remove tracehook_signal_handler
       task_work: Remove unnecessary include from posix_timers.h
       task_work: Introduce task_work_pending
       task_work: Call tracehook_notify_signal from get_signal on all architectures
       task_work: Decouple TIF_NOTIFY_SIGNAL and task_work
       signal: Move set_notify_signal and clear_notify_signal into sched/signal.h
       resume_user_mode: Remove #ifdef TIF_NOTIFY_RESUME in set_notify_resume
       resume_user_mode: Move to resume_user_mode.h
       tracehook: Remove tracehook.h
       ptrace: Move setting/clearing ptrace_message into ptrace_stop
       ptrace: Return the signal to continue with from ptrace_stop
 
 Jann Horn (1):
       ptrace: Check PTRACE_O_SUSPEND_SECCOMP permission on PTRACE_SEIZE

7203062171 TTY/Serial driver changes for 5.18-rc1 
Here are the big set of tty and serial driver changes for 5.18-rc1.
 
 Nothing major, some more good cleanups from Jiri and 2 new serial
 drivers.  Highlights include:
 	- termbits cleanups
 	- export symbol cleanups and other core cleanups from Jiri Slaby
 	- new sunplus and mvebu uart drivers (amazing that people are

dfdc1de642 Staging driver update for 5.18-rc1 
Here is the big set of staging driver updates for 5.18-rc1.
 
 Loads of tiny cleanups for almost all staging drivers in here, nothing
 major at all.  Highlights include:
 	- remove the ashmem Android driver.  It is long-dead and if
 	  there are any legacy userspace applications still using it,
 	  the Android kernel images will maintain it, the community
 	  shouldn't care about it anymore
 	- wfx wifi driver major cleanups.  Should be ready to merge out
 	  of staging soon, and will coordinate with the wifi maintainers
 	  after -rc1 is out
 	- major cleanups and unwinding of the layers of the r8188eu
 	  driver.  It's amazing just how many unneeded layers of
 	  abstraction is in there, just when we think it's done, another
 	  is found...
 	- lots of tiny coding style cleanups in many other staging
 	  drivers.
 
 There will be merge conflict with a fbtft change and the spi driver
 changes in your tree, but it's pretty obvious what to do (the function
 shouldn't return anything.)
 
 All have been in linux-next for a while with no reported problems.

 	- usb gadget audio driver improvements
 	- usb gadget storage fixes to work with OS-X
 	- lots of other small usb gadget fixes and updates
 	- USB DWC3 driver improvements for more hardware types
 	- Lots of other small USB driver improvements
 	- DTS updates for some USB platforms
 
 Note, the DTS updates will have a merge conflict in your tree.  The
 fixup should be simple, but if not, I can provide a merged tree if

9bf3fc5007 Devicetree updates for v5.18: 
- Add Krzysztof Kozlowski as co-maintainer for DT bindings providing
   much needed help.
 
 - DT schema validation now takes DTB files as input rather than
   intermediate YAML files. This decouples the validation from the source
   level syntax information. There's a bunch of schema fixes as a result
   of switching to DTB based validation which exposed some errors
   and incomplete schemas and examples.

Pull devicetree updates from Rob Herring:

 - Add Krzysztof Kozlowski as co-maintainer for DT bindings providing
   much needed help.

 - DT schema validation now takes DTB files as input rather than
   intermediate YAML files. This decouples the validation from the
   source level syntax information. There's a bunch of schema fixes as a
   result of switching to DTB based validation which exposed some errors
   and incomplete schemas and examples.

 - Kbuild improvements to explicitly warn users running 'make
   dt_binding_check' on missing yamllint

 - Expand DT_SCHEMA_FILES kbuild variable to take just a partial
   filename or path instead of the full path to 1 file.

 - Convert various bindings to schema format: mscc,vsc7514-switch,

52d543b549 Minor fixes for IPMI 
Little fixes for various things people have noticed.
 
 One enhancement, the IPMI over IPMB (I2c) is modified to allow it to
 take a separate sender and receiver device.  The Raspberry Pi has an
 I2C slave device that cannot send.

- several changes to how snap context and snap realms are tracked

   needless iteration over all inodes in the snap realm.

 - average latency is now maintained for all metrics (Venky Shankar)
 
 - some tweaks around handling inline data to make it fit better with

Core
 ----
 
  - Introduce XDP multi-buffer support, allowing the use of XDP with
    jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
 
  - Speed up netns dismantling (5x) and lower the memory cost a little.
    Remove unnecessary per-netns sockets. Scope some lists to a netns.
    Cut down RCU syncing. Use batch methods. Allow netdev registration
    to complete out of order.
 
  - Support distinguishing timestamp types (ingress vs egress) and
    maintaining them across packet scrubbing points (e.g. redirect).
 
  - Continue the work of annotating packet drop reasons throughout
    the stack.
 
  - Switch netdev error counters from an atomic to dynamically
    allocated per-CPU counters.
 
  - Rework a few preempt_disable(), local_irq_save() and busy waiting
    sections problematic on PREEMPT_RT.
 
  - Extend the ref_tracker to allow catching use-after-free bugs.
 
 BPF
 ---
 
  - Introduce "packing allocator" for BPF JIT images. JITed code is
    marked read only, and used to be allocated at page granularity.
    Custom allocator allows for more efficient memory use, lower
    iTLB pressure and prevents identity mapping huge pages from
    getting split.
 
  - Make use of BTF type annotations (e.g. __user, __percpu) to enforce
    the correct probe read access method, add appropriate helpers.
 
  - Convert the BPF preload to use light skeleton and drop
    the user-mode-driver dependency.
 
  - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
    its use as a packet generator.
 
  - Allow local storage memory to be allocated with GFP_KERNEL if called
    from a hook allowed to sleep.
 
  - Introduce fprobe (multi kprobe) to speed up mass attachment (arch
    bits to come later).
 
  - Add unstable conntrack lookup helpers for BPF by using the BPF
    kfunc infra.
 
  - Allow cgroup BPF progs to return custom errors to user space.
 
  - Add support for AF_UNIX iterator batching.
 
  - Allow iterator programs to use sleepable helpers.
 
  - Support JIT of add, and, or, xor and xchg atomic ops on arm64.
 
  - Add BTFGen support to bpftool which allows to use CO-RE in kernels
    without BTF info.
 
  - Large number of libbpf API improvements, cleanups and deprecations.
 
 Protocols
 ---------
 
  - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
 
  - Adjust TSO packet sizes based on min_rtt, allowing very low latency
    links (data centers) to always send full-sized TSO super-frames.
 
  - Make IPv6 flow label changes (AKA hash rethink) more configurable,
    via sysctl and setsockopt. Distinguish between server and client
    behavior.
 
  - VxLAN support to "collect metadata" devices to terminate only
    configured VNIs. This is similar to VLAN filtering in the bridge.
 
  - Support inserting IPv6 IOAM information to a fraction of frames.
 
  - Add protocol attribute to IP addresses to allow identifying where
    given address comes from (kernel-generated, DHCP etc.)
 
  - Support setting socket and IPv6 options via cmsg on ping6 sockets.
 
  - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
    Define dscp_t and stop taking ECN bits into account in fib-rules.
 
  - Add support for locked bridge ports (for 802.1X).
 
  - tun: support NAPI for packets received from batched XDP buffs,
    doubling the performance in some scenarios.
 
  - IPv6 extension header handling in Open vSwitch.
 
  - Support IPv6 control message load balancing in bonding, prevent
    neighbor solicitation and advertisement from using the wrong port.
    Support NS/NA monitor selection similar to existing ARP monitor.
 
  - SMC
    - improve performance with TCP_CORK and sendfile()
    - support auto-corking
    - support TCP_NODELAY
 
  - MCTP (Management Component Transport Protocol)
    - add user space tag control interface
    - I2C binding driver (as specified by DMTF DSP0237)
 
  - Multi-BSSID beacon handling in AP mode for WiFi.
 
  - Bluetooth:
    - handle MSFT Monitor Device Event
    - add MGMT Adv Monitor Device Found/Lost events
 
  - Multi-Path TCP:
    - add support for the SO_SNDTIMEO socket option
    - lots of selftest cleanups and improvements
 
  - Increase the max PDU size in CAN ISOTP to 64 kB.
 
 Driver API
 ----------
 
  - Add HW counters for SW netdevs, a mechanism for devices which
    offload packet forwarding to report packet statistics back to
    software interfaces such as tunnels.
 
  - Select the default NIC queue count as a fraction of number of
    physical CPU cores, instead of hard-coding to 8.
 
  - Expose devlink instance locks to drivers. Allow device layer of
    drivers to use that lock directly instead of creating their own
    which always runs into ordering issues in devlink callbacks.
 
  - Add header/data split indication to guide user space enabling
    of TCP zero-copy Rx.
 
  - Allow configuring completion queue event size.
 
  - Refactor page_pool to enable fragmenting after allocation.
 
  - Add allocation and page reuse statistics to page_pool.
 
  - Improve Multiple Spanning Trees support in the bridge to allow
    reuse of topologies across VLANs, saving HW resources in switches.

    - replay and offload of host VLAN entries
    - offload of static and local FDB entries on LAG interfaces
    - FDB isolation and unicast filtering

ed4643521e ARM: DT updates for 5.18 
After a somewhat quiet 5.17 release, the size of the DT changes
 is a bit larger again. There are nine new SoC that get added,
 all of them related to existing platforms:
 
  - Airoha (formerly Mediatek/EcoNet) EN7523 networking SoC and EVB
 
  - Mediatek mt6582 tablet platform with the Prestigio PMT5008 3G tablet
 
  - Microchip Lan966 networking SoC and it evaluation board
 
  - Qualcomm Snapdragon 625/632 midrange phone SoCs, with the
    LG Nexus 5X and Fairphone FP3 phones
 
  - Renesas RZ/G2LC and RZ/V2L general-purpose embedded SoCs,
    along with their evaluation boards
 
  - Samsung Exynos 850 phone SoC and reference board

 Support for additional functionality in existing dts files is added all
 over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91, Allwinner,
 i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and Broadcom.
 
 Samsung has a rework for its pinctrl schema that is a bit tricky and
 requires driver changes to be included here.
 
 A few more platforms only have smaller cleanups and DT Schema fixes,
 this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.
 
 The new machines are really too many to list, but I'll do it anyway:
 
  Allwinner:
    - A20-Marsboard development board
 
  Amlogic
   - Amediatek X96-AIR (Amlogic S905X3)
   - CYX A95XF3-AIR (Amlogic S905X3)
   - Haochuangy H96-Max (Amlogic S905X3)
   - Amlogic AQ222 (Amlogic S4)
   - OSMC Vero 4K+ (Amlogic S905D)
 
  Arm Juno
   - Separate DT depending on SCMI firmware version
 
  Aspeed:
   - Quanta S6Q BMC (AST2600)
   - ASRock ROMED8HM3 (AST2500)

   - Ctera C200 V1 NAS (kirkwood)
   - Ctera C200 V2 NAS (armada-370)
 
  Mstar
   - DongShanPiOne, a low-end embedded board
   - Miyoo Mini handheld game console
 
  NXP i.MX:
   - Numerous i.MX8M Mini based boards in even more variations, but
     none based on other SoCs this time:
     Protonic PRT8MM, emCON-MX8M Mini, Toradex Verdin, and
     Gateworks GW7903
 
  Qualcomm:
   - Google Herobrine R1 Chromebook platform (Snapdragon 7c Gen 3)
   - SHIFT6mq phone (Snapdragon 845)
   - Samsung Galaxy Book2 (Snapdragon 850)
   - Snapdragon 8 Gen 1 Hardware Development Kit

baaa68a979 ARM: SoC updates for 5.18 
SoC specific code is generally used for older platforms that don't (yet)
 use device tree to do the same things.
 
  - Support is added for i.MXRT10xx, a Cortex-M7 based microcontroller
    from NXP. At the moment this is still incomplete as other portions
    are merged through different trees.
 
  - Long abandoned support for running NOMMU ARMv4 or ARMv5 platforms
    gets removed, now the Arm NOMMU platforms are limited to the
    Cortex-M family of microcontrollers
 
  - Two old PXA boards get removed, along with corresponding driver
    bits.
 
  - Continued cleanup of the Intel IXP4xx platforms, removing some
    remnants of the old board files.
 
  - Minor Cleanups and fixes for Orion, PXA, MMP, Mstar, Samsung
 
  - CPU idle support for AT91
 
  - A system controller driver for Polarfire

194dfe88d6 asm-generic updates for 5.18 
There are three sets of updates for 5.18 in the asm-generic tree:
 
  - The set_fs()/get_fs() infrastructure gets removed for good. This
    was already gone from all major architectures, but now we can
    finally remove it everywhere, which loses some particularly
    tricky and error-prone code.
    There is a small merge conflict against a parisc cleanup, the
    solution is to use their new version.
 
  - The nds32 architecture ends its tenure in the Linux kernel. The
    hardware is still used and the code is in reasonable shape, but
    the mainline port is not actively maintained any more, as all
    remaining users are thought to run vendor kernels that would never
    be updated to a future release.
    There are some obvious conflicts against changes to the removed
    files.
 
  - A series from Masahiro Yamada cleans up some of the uapi header
    files to pass the compile-time checks.

 "There are three sets of updates for 5.18 in the asm-generic tree:

   - The set_fs()/get_fs() infrastructure gets removed for good.

     This was already gone from all major architectures, but now we can
     finally remove it everywhere, which loses some particularly tricky
     and error-prone code. There is a small merge conflict against a
     parisc cleanup, the solution is to use their new version.

   - The nds32 architecture ends its tenure in the Linux kernel.

     The hardware is still used and the code is in reasonable shape, but
     the mainline port is not actively maintained any more, as all
     remaining users are thought to run vendor kernels that would never
     be updated to a future release.

   - A series from Masahiro Yamada cleans up some of the uapi header
     files to pass the compile-time checks"

5db1c2dbc0 dt-bindings: nvmem: add U-Boot environment variables binding 
U-Boot uses environment variables for storing device setup data. It
usually needs to be accessed by a bootloader, kernel and often
user-space.

This binding allows describing environment data located in a raw flash
partition. It's treated as NVMEM device and can be reused later for
other storage devices.

Using DT should be cleaner than hardcoding & duplicating such info in
multiple places. Bootloader & kernel can share DTS and user-space can
try reading it too or just have correct data exposed by a kernel.

A custom "compatible" string allows system to automatically load
relevant NVMEM driver but phandle can be also used for reading raw
location.

40037e4f8b sound updates for 5.18 
It's been a fairly calm development cycle.  There are a few
 last-minute ALSA core fixes, most notably for covering PCM ioctl
 races, but the most of rest are device-specific changes.
 
 Below are some highlights:
 
 * ALSA core:
 - Fixes for PCM ioctl races that may lead to UAF
 - Fix for oversized allocations in PCM OSS layer
 
 * ASoC:
 - Start of moving SoF to support multiple IPC mechanisms
 - Use of NHLT ACPI table to reduce the amount of quirking required for
   Intel systems
 - Preliminary works forthcoming Intel AVS driver for legacy Intel DSP
   firmwares
 - Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with
   TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek
   MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas
   RZ/V2L, Texas Instruments TAS585M
 
 * HD-audio:
 - Driver re-binding fix for HD-audio
 - Updates for Intel ADL and Tegra234, various platform quirks for
   Dell, HP, Lenovo, ASUS, Samsung and Clevo machines
 
 * USB-audio:
 - Quirk updates for Scarlett2, RODE, Corsair devices
