Benjamin Tissoires 904e28c6de Merge branch 'for-6.3/hid-bpf' into for-linus
Initial support of HID-BPF (Benjamin Tissoires)

The history is a little long for this series, as it was intended to be
sent for v6.2. However some last minute issues forced us to postpone it
to v6.3.

Conflicts:
* drivers/hid/i2c-hid/Kconfig:
  commit bf7660dab3 ("HID: stop drivers from selecting CONFIG_HID")
  conflicts with commit 2afac81dd1 ("HID: fix I2C_HID not selected
  when I2C_HID_OF_ELAN is")
  the resolution is simple enough: just drop the "default" and "select"
  lines as the new commit from Arnd is doing

Jeremy Kerr 0f4d261989 dt-bindings: mfd/syscon: Add resets property
Simple syscon devices may require deassertion of a reset signal in order
to access their register set. This change adds the `resets` property from
reset.yaml#/properties/resets (referenced through core.yaml), specifying
a maxItems of 1 for a single (optional) reset descriptor.

This will allow a future change to the syscon driver to implement reset
control.

Linus Torvalds 5b7c4cabbb Networking changes for 6.3.
Core
 ----
 
  - Add dedicated kmem_cache for typical/small skb->head, avoid having
    to access struct page at kfree time, and improve memory use.
 
  - Introduce sysctl to set default RPS configuration for new netdevs.
 
  - Define Netlink protocol specification format which can be used
    to describe messages used by each family and auto-generate parsers.
    Add tools for generating kernel data structures and uAPI headers.
 
  - Expose all net/core sysctls inside netns.
 
  - Remove 4s sleep in netpoll if carrier is instantly detected on boot.
 
  - Add configurable limit of MDB entries per port, and port-vlan.
 
  - Continue populating drop reasons throughout the stack.
 
  - Retire a handful of legacy Qdiscs and classifiers.
 
 Protocols
 ---------
 
  - Support IPv4 big TCP (TSO frames larger than 64kB).
 
  - Add IP_LOCAL_PORT_RANGE socket option, to control local port range
    on socket by socket basis.
 
  - Track and report in procfs number of MPTCP sockets used.
 
  - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
    path manager.
 
  - IPv6: don't check net.ipv6.route.max_size and rely on garbage
    collection to free memory (similarly to IPv4).
 
  - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
 
  - ICMP: add per-rate limit counters.
 
  - Add support for user scanning requests in ieee802154.
 
  - Remove static WEP support.
 
  - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
    reporting.
 
  - WiFi 7 EHT channel puncturing support (client & AP).
 
 BPF
 ---
 
  - Add a rbtree data structure following the "next-gen data structure"
    precedent set by recently added linked list, that is, by using
    kfunc + kptr instead of adding a new BPF map type.
 
  - Expose XDP hints via kfuncs with initial support for RX hash and
    timestamp metadata.
 
  - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
    to better support decap on GRE tunnel devices not operating
    in collect metadata.
 
  - Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
 
  - Remove the need for trace_printk_lock for bpf_trace_printk
    and bpf_trace_vprintk helpers.
 
  - Extend libbpf's bpf_tracing.h support for tracing arguments of
    kprobes/uprobes and syscall as a special case.
 
  - Significantly reduce the search time for module symbols
    by livepatch and BPF.
 
  - Enable cpumasks to be used as kptrs, which is useful for tracing
    programs tracking which tasks end up running on which CPUs in
    different time intervals.
 
  - Add support for BPF trampoline on s390x and riscv64.
 
  - Add capability to export the XDP features supported by the NIC.
 
  - Add __bpf_kfunc tag for marking kernel functions as kfuncs.
 
  - Add cgroup.memory=nobpf kernel parameter option to disable BPF
    memory accounting for container environments.
 
 Netfilter
 ---------
 
  - Remove the CLUSTERIP target. It has been marked as obsolete
    for years, and we still have WARN splats wrt. races of
    the out-of-band /proc interface installed by this target.
 
  - Add 'destroy' commands to nf_tables. They are identical to
    the existing 'delete' commands, but do not return an error if
    the referenced object (set, chain, rule...) did not exist.
 
 Driver API
 ----------
 
  - Improve cpumask_local_spread() locality to help NICs set the right
    IRQ affinity on AMD platforms.
 
  - Separate C22 and C45 MDIO bus transactions more clearly.
 
  - Introduce new DCB table to control DSCP rewrite on egress.
 
  - Support configuration of Physical Layer Collision Avoidance (PLCA)
    Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
    shared medium Ethernet.
 
  - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
    preemption of low priority frames by high priority frames.
 
  - Add support for controlling MACSec offload using netlink SET.
 
  - Rework devlink instance refcounts to allow registration and
    de-registration under the instance lock. Split the code into multiple
    files, drop some of the unnecessarily granular locks and factor out
    common parts of netlink operation handling.
 
  - Add TX frame aggregation parameters (for USB drivers).
 
  - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
    messages with notifications for debug.
 
  - Allow offloading of UDP NEW connections via act_ct.
 
  - Add support for per action HW stats in TC.
 
  - Support hardware miss to TC action (continue processing in SW from
    a specific point in the action chain).
 
  - Warn if old Wireless Extension user space interface is used with
    modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
    for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
    interface instead.
 
  - Improve the CAN bit timing configuration. Use extack to return error
    messages directly to user space, update the SJW handling, including
    the definition of a new default value that will benefit CAN-FD
    controllers, by increasing their oscillator tolerance.

     modern cfg80211/mac80211 drivers. Do not support Wireless
     Extensions for Wi-Fi 7 devices at all. Everyone should switch to
     using nl80211 interface instead.

   - Improve the CAN bit timing configuration. Use extack to return
     error messages directly to user space, update the SJW handling,
     including the definition of a new default value that will benefit
     CAN-FD controllers, by increasing their oscillator tolerance.

Linus Torvalds 8bf1a529cd arm64 updates for 6.3:
- Support for arm64 SME 2 and 2.1. SME2 introduces a new 512-bit
   architectural register (ZT0, for the look-up table feature) that Linux
   needs to save/restore.
 
 - Include TPIDR2 in the signal context and add the corresponding
   kselftests.
 
 - Perf updates: Arm SPEv1.2 support, HiSilicon uncore PMU updates, ACPI
   support to the Marvell DDR and TAD PMU drivers, reset DTM_PMU_CONFIG
   (ARM CMN) at probe time.
 
 - Support for DYNAMIC_FTRACE_WITH_CALL_OPS on arm64.
 
 - Permit EFI boot with MMU and caches on. Instead of cleaning the entire
   loaded kernel image to the PoC and disabling the MMU and caches before
   branching to the kernel bare metal entry point, leave the MMU and
   caches enabled and rely on EFI's cacheable 1:1 mapping of all of
   system RAM to populate the initial page tables.
 
 - Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64
   kernel (the arm32 kernel only defines the values).
 
 - Harden the arm64 shadow call stack pointer handling: stash the shadow
   stack pointer in the task struct on interrupt, load it directly from
   this structure.
 
 - Signal handling cleanups to remove redundant validation of size
   information and avoid reading the same data from userspace twice.
 
 - Refactor the hwcap macros to make use of the automatically generated
   ID registers. It should make new hwcaps writing less error prone.
 
 - Further arm64 sysreg conversion and some fixes.
 
 - arm64 kselftest fixes and improvements.
 
 - Pointer authentication cleanups: don't sign leaf functions, unify
   asm-arch manipulation.
 
 - Pseudo-NMI code generation optimisations.
 
 - Minor fixes for SME and TPIDR2 handling.
 
 - Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable, replace
   strtobool() to kstrtobool() in the cpufeature.c code, apply dynamic
   shadow call stack in two passes, intercept pfn changes in set_pte_at()
   without the required break-before-make sequence, attempt to dump all
   instructions on unhandled kernel faults.

 - Support for arm64 SME 2 and 2.1. SME2 introduces a new 512-bit
   architectural register (ZT0, for the look-up table feature) that
   Linux needs to save/restore

 - Include TPIDR2 in the signal context and add the corresponding
   kselftests

 - Perf updates: Arm SPEv1.2 support, HiSilicon uncore PMU updates, ACPI
   support to the Marvell DDR and TAD PMU drivers, reset DTM_PMU_CONFIG
   (ARM CMN) at probe time

 - Support for DYNAMIC_FTRACE_WITH_CALL_OPS on arm64

 - Permit EFI boot with MMU and caches on. Instead of cleaning the
   entire loaded kernel image to the PoC and disabling the MMU and
   caches before branching to the kernel bare metal entry point, leave
   the MMU and caches enabled and rely on EFI's cacheable 1:1 mapping of
   all of system RAM to populate the initial page tables

 - Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64
   kernel (the arm32 kernel only defines the values)

 - Harden the arm64 shadow call stack pointer handling: stash the shadow
   stack pointer in the task struct on interrupt, load it directly from
   this structure

 - Signal handling cleanups to remove redundant validation of size
   information and avoid reading the same data from userspace twice

 - Refactor the hwcap macros to make use of the automatically generated
   ID registers. It should make new hwcaps writing less error prone

 - Further arm64 sysreg conversion and some fixes

 - arm64 kselftest fixes and improvements

 - Pointer authentication cleanups: don't sign leaf functions, unify
   asm-arch manipulation

 - Pseudo-NMI code generation optimisations

 - Minor fixes for SME and TPIDR2 handling

 - Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable,
   replace strtobool() to kstrtobool() in the cpufeature.c code, apply
   dynamic shadow call stack in two passes, intercept pfn changes in
   set_pte_at() without the required break-before-make sequence, attempt
   to dump all instructions on unhandled kernel faults

Paul E. McKenney b743852ccc Allow forcing unconditional bootconfig processing
The BOOT_CONFIG family of Kconfig options allows a bootconfig file
containing kernel boot parameters to be embedded into an initrd or into
the kernel itself.  This can be extremely useful when deploying kernels
in cases where some of the boot parameters depend on the kernel version
rather than on the server hardware, firmware, or workload.

Unfortunately, the "bootconfig" kernel parameter must be specified in
order to cause the kernel to look for the embedded bootconfig file,
and it clearly does not help to embed this "bootconfig" kernel parameter
into that file.

Therefore, provide a new BOOT_CONFIG_FORCE Kconfig option that causes the
kernel to act as if the "bootconfig" kernel parameter had been specified.
In other words, kernels built with CONFIG_BOOT_CONFIG_FORCE=y will look
for the embedded bootconfig file even when the "bootconfig" kernel
parameter is omitted.  This permits kernel-version-dependent kernel
boot parameters to be embedded into the kernel image without the need to
(for example) update large numbers of boot loaders.

Linus Torvalds bcf5470eb4 s390 updates for 6.3 merge window
- Large cleanup of the con3270/tty3270 driver. Among others this fixes:
   * Background Color Support
   * ASCII Line Character Support
   * VT100 Support
   * Geometries other than 80x24
 
 - Cleanup and improve cmpxchg() code. Also add cmpxchg_user_key() to
   uaccess functions, which will be used by KVM to access KVM guest memory
   with a specific storage key.
 
 - Add support for user space events counting to CPUMF.
 
 - Cleanup the vfio/ccw code, which also allows now to properly support 2K
   Format-2 IDALs.
 
 - Move kernel page table allocation and initialization to decompressor,
   which finally allows to enter the kernel with dynamic address translation
   enabled. This in turn allows to get rid of code with special handling in
   the kernel, which has to distinguish if DAT is on or off.
 
 - Replace kretprobe with rethook.
 
 - Various improvements to vfio/ap queue resets:
   * Use TAPQ to verify completion of a reset in progress rather than
     multiple invocations of ZAPQ.
   * Check TAPQ response codes when verifying successful completion of ZAPQ.
   * Fix erroneous handling of some error response codes.
   * Increase the maximum amount of time to wait for successful completion
     of ZAPQ.
 
 - Rework system call wrappers to get rid of alias functions, which were
   only left on s390.
 
 - Cleanup diag288_wdt watchdog driver. It has been agreed on with Guenter
   Roeck that this goes upstream via the s390 tree.
 
 - Add missing loadparm parameter handling for list-directed ECKD ipl/reipl.
 
 - Various improvements to memory detection code.
 
 - Remove arch_cpu_idle_time() since the current implementation is broken,
   and allows user space observable accounted idle times which can
   temporarily decrease.
 
 - Add Reset DAT-Protection support: (only) allow to change PTEs from RO to
   RW with a new RDP instruction. Unlike the currently used IPTE
   instruction, this does not necessarily guarantee that TLBs of all CPUs
   are synchronously flushed; and that remote CPUs can see spurious
   protection faults. The overall improvement for not requiring an all CPU
   synchronization, like it is required with IPTE, should be beneficial.
 
 - Fix KFENCE page fault reporting.
 
 - Smaller cleanups and improvement all over the place.

Merge tag 'thermal-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control updates from Rafael Wysocki:
 "The majority of changes here are related to the general switch-over to
  using arrays of generic trip point structures registered along with a
  thermal zone instead of trip point callbacks (this has been done
  mostly by Daniel Lezcano with some help from yours truly on the Intel
  drivers front).

  Apart from that and the related reorganization of code, there are some
  enhancements of the existing driver and a new Mediatek Low Voltage
  Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
  rework so it will use the generic idle_inject facility for CPU idle
  time injection going forward and it will take additional module
  parameters for specifying the subset of CPUs to be affected by it
  (work done by Srinivas Pandruvada).

  Also included are assorted fixes and a whole bunch of cleanups.

  Specifics:

   - Rework a large bunch of drivers to use the generic thermal trip
     structure and use the opportunity to do more cleanups by removing
     unused functions from the OF code (Daniel Lezcano)

Linus Torvalds 8cc01d43f8 RCU pull request for v6.3
This pull request contains the following branches:
 
 doc.2023.01.05a: Documentation updates.
 
 fixes.2023.01.23a: Miscellaneous fixes, perhaps most notably:
 
 o	Throttling callback invocation based on the number of callbacks
 	that are now ready to invoke instead of on the total number
 	of callbacks.
 
 o	Several patches that suppress false-positive boot-time
 	diagnostics, for example, due to lockdep not yet being
 	initialized.
 
 o	Make expedited RCU CPU stall warnings dump stacks of any tasks
 	that are blocking the stalled grace period.  (Normal RCU CPU
 	stall warnings have doen this for mnay years.)
 
 o	Lazy-callback fixes to avoid delays during boot, suspend, and
 	resume.  (Note that lazy callbacks must be explicitly enabled,
 	so this should not (yet) affect production use cases.)
 
 kvfree.2023.01.03a: Cause kfree_rcu() and friends to take advantage of
 	polled grace periods, thus reducing memory footprint by almost
 	two orders of magnitude, admittedly on a microbenchmark.
 	This series also begins the transition from kfree_rcu(p) to
 	kfree_rcu_mightsleep(p).  This transition was motivated by bugs
 	where kfree_rcu(p), which can block, was typed instead of the
 	intended kfree_rcu(p, rh).
 
 srcu.2023.01.03a: SRCU updates, perhaps most notably fixing a bug that
 	causes SRCU to fail when booted on a system with a non-zero boot
 	CPU.  This surprising situation actually happens for kdump kernels
 	on the powerpc architecture.  It also adds an srcu_down_read()
 	and srcu_up_read(), which act like srcu_read_lock() and
 	srcu_read_unlock(), but allow an SRCU read-side critical section
 	to be handed off from one task to another.
 
 srcu-always.2023.02.02a: Cleans up the now-useless SRCU Kconfig option.
 	There are a few more commits that are not yet acked or pulled
 	into maintainer trees, and these will be in a pull request for
 	a later merge window.
 
 tasks.2023.01.03a: RCU-tasks updates, perhaps most notably these fixes:
 
 o	A strange interaction between PID-namespace unshare and the
 	RCU-tasks grace period that results in a low-probability but
 	very real hang.
 
 o	A race between an RCU tasks rude grace period on a single-CPU
 	system and CPU-hotplug addition of the second CPU that can result
 	in a too-short grace period.
 
 o	A race between shrinking RCU tasks down to a single callback list
 	and queuing a new callback to some other CPU, but where that
 	queuing is delayed for more than an RCU grace period.  This can
 	result in that callback being stranded on the non-boot CPU.
 
 torture.2023.01.05a: Torture-test updates and fixes.
 
 torturescript.2023.01.03a: Torture-test scripting updates and fixes.

Merge tag 'rcu.2023.02.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

Pull RCU updates from Paul McKenney:

 - Documentation updates

 - Miscellaneous fixes, perhaps most notably:

      - Throttling callback invocation based on the number of callbacks
        that are now ready to invoke instead of on the total number of
        callbacks

      - Several patches that suppress false-positive boot-time
        diagnostics, for example, due to lockdep not yet being
        initialized

      - Make expedited RCU CPU stall warnings dump stacks of any tasks
        that are blocking the stalled grace period. (Normal RCU CPU
        stall warnings have done this for many years)

      - Lazy-callback fixes to avoid delays during boot, suspend, and
        resume. (Note that lazy callbacks must be explicitly enabled, so
        this should not (yet) affect production use cases)

 - Make kfree_rcu() and friends take advantage of polled grace periods,
   thus reducing memory footprint by almost two orders of magnitude,
   admittedly on a microbenchmark

   This also begins the transition from kfree_rcu(p) to
   kfree_rcu_mightsleep(p). This transition was motivated by bugs where
   kfree_rcu(p), which can block, was typed instead of the intended
   kfree_rcu(p, rh)

 - SRCU updates, perhaps most notably fixing a bug that causes SRCU to
   fail when booted on a system with a non-zero boot CPU. This
   surprising situation actually happens for kdump kernels on the
   powerpc architecture

   This also adds an srcu_down_read() and srcu_up_read(), which act like
   srcu_read_lock() and srcu_read_unlock(), but allow an SRCU read-side
   critical section to be handed off from one task to another

 - Clean up the now-useless SRCU Kconfig option

   There are a few more commits that are not yet acked or pulled into
   maintainer trees, and these will be in a pull request for a later
   merge window

 - RCU-tasks updates, perhaps most notably these fixes:

      - A strange interaction between PID-namespace unshare and the
        RCU-tasks grace period that results in a low-probability but
        very real hang

      - A race between an RCU tasks rude grace period on a single-CPU
        system and CPU-hotplug addition of the second CPU that can
        result in a too-short grace period

      - A race between shrinking RCU tasks down to a single callback
        list and queuing a new callback to some other CPU, but where
        that queuing is delayed for more than an RCU grace period. This
        can result in that callback being stranded on the non-boot CPU

 - Torture-test updates and fixes

 - Torture-test scripting updates and fixes

 - Provide additional RCU CPU stall-warning information in kernels built
   with CONFIG_RCU_CPU_STALL_CPUTIME=y, and restore the full five-minute
   timeout limit for expedited RCU CPU stall warnings

Linus Torvalds 9e58df973d Updates for the interrupt subsystem:
Core:
 
     - Move the interrupt affinity spreading mechanism into lib/group_cpus
       so it can be used for similar spreading requirements, e.g. in the
       block multi-queue code.
 
       This also contains a first usecase in the block multi-queue code which
       Jens asked to take along with the librarization.
 
     - Improve irqdomain locking to close a number race conditions which
       can be observed with massive parallel device driver probing.
 
     - Enforce and document the semantics of disable_irq() which cannot be
       invoked safely from non-sleepable context.
 
     - Move the IPI multiplexing code from the Apple AIC driver into the
       core. so it can be reused by RISCV.
 
   Drivers:
 
     - Plug OF node refcounting leaks in various drivers.
 
     - Correctly mark level triggered interrupts in the Broadcom L2 drivers.
 
     - The usual small fixes and improvements.
 
     - No new drivers for the record!

Linus Torvalds 560b803067 Updates for timekeeping, timers and clockevent/source drivers:
Core:
 
     - Yet another round of improvements to make the clocksource watchdog
       more robust:
 
       	 - Relax the clocksource-watchdog skew criteria to match the NTP
            criteria.
 
 	 - Temporarily skip the watchdog when high memory latencies are
 	   detected which can lead to false-positives.
 
 	 - Provide an option to enable TSC skew detection even on systems
            where TSC is marked as reliable.
 
       Sigh!
 
     - Initialize the restart block in the nanosleep syscalls to be directed
       to the no restart function instead of doing a partial setup on entry.
 
       This prevents an erroneous restart_syscall() invocation from
       corrupting user space data. While such a situation is clearly a user
       space bug, preventing this is a correctness issue and caters to the
       least suprise principle.
 
     - Ignore the hrtimer slack for realtime tasks in schedule_hrtimeout()
       to align it with the nanosleep semantics.
 
   Drivers:
 
     - The obligatory new driver bindings for Mediatek, Rockchip and RISC-V
       variants.
 
     - Add support for the C3STOP misfeature to the RISC-V timer to handle
       the case where the timer stops in deeper idle state.
 
     - Set up a static key in the RISC-V timer correctly before first use.
 
     - The usual small improvements and fixes all over the place

====================
pull-request: bpf-next 2023-02-17

We've added 64 non-merge commits during the last 7 day(s) which contain
a total of 158 files changed, 4190 insertions(+), 988 deletions(-).

The main changes are:

1) Add a rbtree data structure following the "next-gen data structure"
   precedent set by recently-added linked-list, that is, by using
   kfunc + kptr instead of adding a new BPF map type, from Dave Marchevsky.

2) Add a new benchmark for hashmap lookups to BPF selftests,
   from Anton Protopopov.

3) Fix bpf_fib_lookup to only return valid neighbors and add an option
   to skip the neigh table lookup, from Martin KaFai Lau.

4) Add cgroup.memory=nobpf kernel parameter option to disable BPF memory
   accouting for container environments, from Yafang Shao.

5) Batch of ice multi-buffer and driver performance fixes,
   from Alexander Lobakin.

6) Fix a bug in determining whether global subprog's argument is
   PTR_TO_CTX, which is based on type names which breaks kprobe progs,
   from Andrii Nakryiko.

7) Prep work for future -mcpu=v4 LLVM option which includes usage of
   BPF_ST insn. Thus improve BPF_ST-related value tracking in verifier,
   from Eduard Zingerman.

8) More prep work for later building selftests with Memory Sanitizer
   in order to detect usages of undefined memory, from Ilya Leoshkevich.

9) Fix xsk sockets to check IFF_UP earlier to avoid a NULL pointer
   dereference via sendmsg(), from Maciej Fijalkowski.

10) Implement BPF trampoline for RV64 JIT compiler, from Pu Lehui.

11) Fix BPF memory allocator in combination with BPF hashtab where it could
    corrupt special fields e.g. used in bpf_spin_lock, from Hou Tao.

12) Fix LoongArch BPF JIT to always use 4 instructions for function
    address so that instruction sequences don't change between passes,
    from Hengqi Chen.

Donglin Peng 8478cca1e3 tracing/probe: add a char type to show the character value of traced arguments
There are scenes that we want to show the character value of traced
arguments other than a decimal or hexadecimal or string value for debug
convinience. I add a new type named 'char' to do it and a new test case
file named 'kprobe_args_char.tc' to do selftest for char type.

For example:

The to be traced function is 'void demo_func(char type, char *name);', we
can add a kprobe event as follows to show argument values as we want:

echo  'p:myprobe demo_func $arg1:char +0($arg2):char[5]' > kprobe_events

we will get the following trace log:

... myprobe: (demo_func+0x0/0x29) arg1='A' arg2={'b','p','f','1',''}

Linus Torvalds 950b6662e2 SoC: DT changes for 6.3
About a quarter of the changes are for 32-bit arm, mostly filling in
 device support for existing machines and adding minor cleanups, mostly
 for Qualcomm and Samsung based machines.
 
 Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from
 Rockchips that have been around for a while but were lacking kernel
 support so far: RV1126 is a Vision SoC with an NPU and is used in the
 Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design for
 TV boxes and so far only comes with a dts for its refernece design.
 
 The other 32-bit boards that were added are two ASpeed AST2600 based BMC
 boards, the Microchip sam9x60_curiosity development board (Armv5 based!),
 the Enclustra PE1 FPGA-SoM baseboard, and a few more boards for i.MX53
 and i.MX6ULL.
 
 On the RISC-V side, there are fewer patches, but a total of ten new
 single-board computers based on variations of the Allwinner D1/T113 chip,
 plus one more board based on Microchip Polarfire.
 
 As usual, arm64 has by far the most changes here, with over 700 non-merge
 changesets, among them over 400 alone for Qualcomm. The newly added SoCs
 this time are all recent high-end embedded SoCs for various markets,
 each on comes with support for its reference board:
 
  - Qualcomm SM8550 (Snapdragon 8 Gen 2) for mobile phones
  - Qualcomm QDU1000/QRU1000 5G RAN platform
  - Rockchips RK3588/RK3588s for tablets, chromebooks and SBCs
  - TI J784S4 for industrial and automotive applications
 
 In total, there are 46 new arm64 machines:
  - Reference platforms for each of the five new SoCs
  - Three Amlogic based development boards
  - Six embedded machines based on NXP i.MX8MM and i.MX8MP
  - The Mediatek mt7986a based Banana Pi R3 router
  - Six tablets based on Qualcomm MSM8916 (Snapdragon 410),
    SM6115 (Snapdragon 662) and SM8250 (Snapdragon 865)
  - Two LTE dongles, also based on MSM8916
  - Seven mobile phones, based on Qualcomm MSM8953 (Snapdragon 610),
    SDM450 and SDM632
  - Three chromebooks based on Qualcomm SC7280 (Snapdragon 7c)
  - Nine development boards based on Rockchips RK3588, RK3568,
    RK3566 and RK3328.
  - Five development machines based on TI K3 (AM642/AM654/AM68/AM69)
 
 The cleanup of dtc warnings continues across all platforms, adding
 to the total number of changes.

Linus Torvalds b32c6e029c ARM: SoC updates for 6.3
The majority of the changes are for the OMAP2 platform, mostly
 removing some dead code that got left behind from previous cleanups.
 
 Aside from that, there are very minor updates and correctness fixes for
 Zynq, i.MX, Samsung, Broadcom, AT91, ep93xx, and OMAP1.

Linus Torvalds ff0c7e1862 ARM: unused boardfile removal for 6.3
This is a follow-up to the deprecation of most of the old-style board
 files that was merged in linux-6.0, removing them for good.
 
 This branch is almost exclusively dead code removal based on those
 annotations. Some device driver removals went through separate subsystem
 trees, but the majority is in the same branch, in order to better handle
 dependencies between the patches and avoid breaking bisection.
 
 Unfortunately that leads to merge conflicts against other changes in the
 subsystem trees, but they should all be trivial to resolve by removing
 the files.
 
 See commit 7d0d3fa733 ("Merge tag 'arm-boardfiles-6.0' of
 git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
 description of which machines were marked unused and are now removed. The
 only removals that got postponed are Terastation WXL (mv78xx0) and
 Jornada720 (StrongARM1100), which turned out to still have potential
 users.

Linus Torvalds 6639c3ce7f fsverity updates for 6.3
Fix the longstanding implementation limitation that fsverity was only
 supported when the Merkle tree block size, filesystem block size, and
 PAGE_SIZE were all equal.  Specifically, add support for Merkle tree
 block sizes less than PAGE_SIZE, and make ext4 support fsverity on
 filesystems where the filesystem block size is less than PAGE_SIZE.
 
 Effectively, this means that fsverity can now be used on systems with
 non-4K pages, at least on ext4.  These changes have been tested using
 the verity group of xfstests, newly updated to cover the new code paths.
 
 Also update fs/verity/ to support verifying data from large folios.
 There's also a similar patch for fs/crypto/, to support decrypting data
 from large folios, which I'm including in this pull request to avoid a
 merge conflict between the fscrypt and fsverity branches.
 
 There will be a merge conflict in fs/buffer.c with some of the foliation
 work in the mm tree.  Please use the merge resolution from linux-next.

Pull erofs updates from Gao Xiang:
 "The most noticeable feature for this cycle is per-CPU kthread
  decompression since Android use cases need low-latency I/O handling in
  order to ensure the app runtime performance, currently unbounded
  workqueue latencies are not quite good for production on many aarch64
  hardwares and thus we need to introduce a deterministic expectation
  for these. Decompression is CPU-intensive and it is sleepable for
  EROFS, so other alternatives like decompression under softirq contexts
  are not considered. More details are in the corresponding commit
  message.

  Others are random cleanups around the whole codebase and we will
  continue to clean up further in the next few months.

  Due to Lunar New Year holidays, some other new features were not
  completely reviewed and solidified as expected and we may delay them
  into the next version.

Merge tag 'fs.idmapped.v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping

Pull vfs idmapping updates from Christian Brauner:

 - Last cycle we introduced the dedicated struct mnt_idmap type for
   mount idmapping and the required infrastucture in 256c8aed2b ("fs:
   introduce dedicated idmap type for mounts"). As promised in last
   cycle's pull request message this converts everything to rely on
   struct mnt_idmap.

   Currently we still pass around the plain namespace that was attached
   to a mount. This is in general pretty convenient but it makes it easy
   to conflate namespaces that are relevant on the filesystem with
   namespaces that are relevant on the mount level. Especially for
   non-vfs developers without detailed knowledge in this area this was a
   potential source for bugs.

   This finishes the conversion. Instead of passing the plain namespace
   around this updates all places that currently take a pointer to a
   mnt_userns with a pointer to struct mnt_idmap.

   Now that the conversion is done all helpers down to the really
   low-level helpers only accept a struct mnt_idmap argument instead of
   two namespace arguments.

   Conflating mount and other idmappings will now cause the compiler to
   complain loudly thus eliminating the possibility of any bugs. This
   makes it impossible for filesystem developers to mix up mount and
   filesystem idmappings as they are two distinct types and require
   distinct helpers that cannot be used interchangeably.

   Everything associated with struct mnt_idmap is moved into a single
   separate file. With that change no code can poke around in struct
   mnt_idmap. It can only be interacted with through dedicated helpers.
   That means all filesystems are and all of the vfs is completely
   oblivious to the actual implementation of idmappings.

   We are now also able to extend struct mnt_idmap as we see fit. For
   example, we can decouple it completely from namespaces for users that
   don't require or don't want to use them at all. We can also extend
   the concept of idmappings so we can cover filesystem specific
   requirements.

   In combination with the vfs{g,u}id_t work we finished in v6.2 this
   makes this feature substantially more robust and thus difficult to
   implement wrong by a given filesystem and also protects the vfs.

 - Enable idmapped mounts for tmpfs and fulfill a longstanding request.

   A long-standing request from users had been to make it possible to
   create idmapped mounts for tmpfs. For example, to share the host's
   tmpfs mount between multiple sandboxes. This is a prerequisite for
   some advanced Kubernetes cases. Systemd also has a range of use-cases
   to increase service isolation. And there are more users of this.

   However, with all of the other work going on this was way down on the
   priority list but luckily someone other than ourselves picked this
   up.

   As usual the patch is tiny as all the infrastructure work had been
   done multiple kernel releases ago. In addition to all the tests that
   we already have I requested that Rodrigo add a dedicated tmpfs
   testsuite for idmapped mounts to xfstests. It is to be included into
   xfstests during the v6.3 development cycle. This should add a slew of
   additional tests.

Paolo Bonzini 4090871d77 KVM/arm64 updates for 6.3
- Provide a virtual cache topology to the guest to avoid
    inconsistencies with migration on heterogenous systems. Non secure
    software has no practical need to traverse the caches by set/way in
    the first place.
 
  - Add support for taking stage-2 access faults in parallel. This was an
    accidental omission in the original parallel faults implementation,
    but should provide a marginal improvement to machines w/o FEAT_HAFDBS
    (such as hardware from the fruit company).
 
  - A preamble to adding support for nested virtualization to KVM,
    including vEL2 register state, rudimentary nested exception handling
    and masking unsupported features for nested guests.
 
  - Fixes to the PSCI relay that avoid an unexpected host SVE trap when
    resuming a CPU when running pKVM.
 
  - VGIC maintenance interrupt support for the AIC
 
  - Improvements to the arch timer emulation, primarily aimed at reducing
    the trap overhead of running nested.
 
  - Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
    interest of CI systems.
 
  - Avoid VM-wide stop-the-world operations when a vCPU accesses its own
    redistributor.
 
  - Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions
    in the host.
 
  - Aesthetic and comment/kerneldoc fixes
 
  - Drop the vestiges of the old Columbia mailing list and add myself as
    co-maintainer
 
 This also drags in a couple of branches to avoid conflicts:
 
  - The shared 'kvm-hw-enable-refactor' branch that reworks
    initialization, as it conflicted with the virtual cache topology
    changes.
 
  - arm64's 'for-next/sme2' branch, as the PSCI relay changes, as both
    touched the EL2 initialization code.

 - Add support for taking stage-2 access faults in parallel. This was an

Switching to using the silkscreened version number will ease confusion &

Guenter Roeck 5720a18baa hwmon: Deprecate [devm_]hwmon_device_register_with_groups
Even though the hardware monitoring documentation already stated that new
drivers should use [devm_]devm_hwmon_device_register_with_info() to
register with the hardware monitoring subsystem, we still get submissions
for new drivers using the older APIs. There is no benefit to use those
APIs. On the contrary, using the older APIs results in substantially larger
code size. Explicitly deprecate [devm_]hwmon_device_register_with_groups()
to ensure that all new drivers use the latest API.

Daniel Starke 72206cc730 tty: n_gsm: add keep alive support
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapters 5.4.6.3.4 and 5.1.8.1.3 describe the test
command which can be used to test the mux connection between both sides.

Currently, no algorithm is implemented to make use of this command. This
requires that each multiplexed upper layer protocol supervises the
underlying muxer connection to handle possible connection losses.

Introduce ioctl commands and functions to optionally enable keep alive
handling via the test command as described in chapter 5.4.6.3.4. A single
incrementing octet "ka_num" is being used for unique identification of each
single keep alive packet. Retries will use the same "ka_num" value as the
original packet. Retry count and interval are taken from the general
parameters N2 and T2.

Add usage description and basic example for the new ioctl to the n_gsm
documentation.

Note that support for the test command is mandatory and already present in
the muxer implementation since the very first version.
Also note that the previous ioctl structure gsm_config cannot be extended
due to missing checks against zero of the field "unused".

Jakub Kicinski 0f19f514de mlx5-updates-2023-02-10
1) From Roi and Mark: MultiPort eswitch support
 
 MultiPort E-Switch builds on newer hardware's capabilities and introduces
 a mode where a single E-Switch is used and all the vports and physical
 ports on the NIC are connected to it.
 
 The new mode will allow in the future a decrease in the memory used by the
 driver and advanced features that aren't possible today.
 
 This represents a big change in the current E-Switch implantation in mlx5.
 Currently, by default, each E-Switch manager manages its E-Switch.
 Steering rules in each E-Switch can only forward traffic to the native
 physical port associated with that E-Switch. While there are ways to target
 non-native physical ports, for example using a bond or via special TC
 rules. None of the ways allows a user to configure the driver
 to operate by default in such a mode nor can the driver decide
 to move to this mode by default as it's user configuration-driven right now.
 
 While MultiPort E-Switch single FDB mode is the preferred mode, older
 generations of ConnectX hardware couldn't support this mode so it was never
 implemented. Now that there is capable hardware present, start the
 transition to having this mode by default.
 
 Introduce a devlink parameter to control MultiPort Eswitch single FDB mode.
 This will allow users to select this mode on their system right now
 and in the future will allow the driver to move to this mode by default.
 
 2) From Jiri: Improvements and fixes for mlx5 netdev's devlink logic
  2.1) Cleanups related to mlx5's devlink port logic

Cristian Ciocaltea 25eba1598c dt-bindings: Fix multi pattern support in DT_SCHEMA_FILES
DT_SCHEMA_FILES used to allow specifying a space separated list of file
paths, but the introduction of partial matches support broke this
feature:

$ make dtbs_check DT_SCHEMA_FILES="path/to/schema1.yaml path/to/schema2.yaml"
[...]
  LINT    Documentation/devicetree/bindings
usage: yamllint [-h] [-] [-c CONFIG_FILE | -d CONFIG_DATA] [--list-files] [...]
                [-v]
                [FILE_OR_DIR ...]
yamllint: error: one of the arguments FILE_OR_DIR - is required
[...]

Restore the lost functionality by preparing a grep filter that is able
to handle multiple search patterns.

Additionally, as suggested by Rob, use ':' instead of ' ' as the
patterns separator char. Hence, the command above becomes:

$ make dtbs_check DT_SCHEMA_FILES="path/to/schema1.yaml:path/to/schema2.yaml"

Saranya Gopal c620f4d5b2 usb: typec: pd: Add higher capability sysfs for sink PDO
28th bit of fixed supply sink PDO represents higher capability.
When this bit is set, the sink device needs more than vsafe5V
(eg: 12 V) to provide full functionality. This patch adds
this higher capability sysfs interface for sink PDO.
28th bit of fixed supply source PDO represents usb_suspend_supported
attribute. This usb_suspend_supported sysfs is already exposed for
source PDOs. This patch adds 'source-capabilities' in
usb_suspend_supported sysfs documentation for additional clarity.

Dave Wysochanski 3e2a036827 Documentation: Fix sysfs path for the NFSv4 client identifier
The sysfs path for the NFS4 client identfier should start with
the path component of 'nfs' for the kset, and then the 'net'
path component for the netns object, followed by the
'nfs_client' path component for the NFS client kobject,
and ending with 'identifier' for the netns_client_id
kobj_attribute.

Merge patch series "dt-bindings: Add a cpu-capacity property for RISC-V"
Conor Dooley <conor@kernel.org> says:

From: Conor Dooley <conor.dooley@microchip.com>

Ever since RISC-V starting using generic arch topology code, the code
paths for cpu-capacity have been there but there's no binding defined to
actually convey the information. Defining the same property as used on
arm seems to be the only logical thing to do, so do it.

[Palmer: This is on top of the fix required to make it work, which
itself wasn't merged until late in the 6.2 cycle and thus pulls in
various other fixes.]

dt-bindings: riscv: add a capacity-dmips-mhz cpu property
Since commit 03f11f03db ("RISC-V: Parse cpu topology during boot.")
RISC-V has used the generic arch topology code, which provides for
disparate CPU capacities. We never defined a binding to acquire this
information from the DT though, so document the one already used by the
generic arch topology code: "capacity-dmips-mhz".

RISC-V uses the same generic topology code as arm64 & while there
currently exists no binding for cpu-capacity on RISC-V, the code paths
can be hit if the property is present.

Move the documentation of cpu-capacity to a shared location, ahead of
defining a binding for capacity-dmips-mhz on RISC-V. Update some

Roi Dayan a32327a3a0 net/mlx5: Lag, Control MultiPort E-Switch single FDB mode
MultiPort E-Switch builds on newer hardware's capabilities and introduces
a mode where a single E-Switch is used and all the vports and physical
ports on the NIC are connected to it.

The new mode will allow in the future a decrease in the memory used by the
driver and advanced features that aren't possible today.

This represents a big change in the current E-Switch implantation in mlx5.
Currently, by default, each E-Switch manager manages its E-Switch.
Steering rules in each E-Switch can only forward traffic to the native
physical port associated with that E-Switch. While there are ways to target
non-native physical ports, for example using a bond or via special TC
rules. None of the ways allows a user to configure the driver
to operate by default in such a mode nor can the driver decide
to move to this mode by default as it's user configuration-driven right now.

While MultiPort E-Switch single FDB mode is the preferred mode, older
generations of ConnectX hardware couldn't support this mode so it was never
implemented. Now that there is capable hardware present, start the
transition to having this mode by default.

Introduce a devlink parameter to control MultiPort E-Switch single FDB mode.
This will allow users to select this mode on their system right now
and in the future will allow the driver to move to this mode by default.

Example:
    $ devlink dev param set pci/0000:00:0b.0 name esw_multiport value 1 \
                  cmode runtime

Linus Torvalds 82eac0c830 Certain AMD processors are vulnerable to a cross-thread return address
predictions bug. When running in SMT mode and one of the sibling threads
 transitions out of C0 state, the other thread gets access to twice as many
 entries in the RSB, but unfortunately the predictions of the now-halted
 logical processor are not purged.  Therefore, the executing processor
 could speculatively execute from locations that the now-halted processor
 had trained the RSB on.
 
 The Spectre v2 mitigations cover the Linux kernel, as it fills the RSB
 when context switching to the idle thread. However, KVM allows a VMM to
 prevent exiting guest mode when transitioning out of C0 using the
 KVM_CAP_X86_DISABLE_EXITS capability can be used by a VMM to change this
 behavior. To mitigate the cross-thread return address predictions bug,
 a VMM must not be allowed to override the default behavior to intercept
 C0 transitions.
 
 These patches introduce a KVM module parameter that, if set, will prevent
 the user from disabling the HLT, MWAIT and CSTATE exits.

Pull kvm fixes from Paolo Bonzini:
 "Certain AMD processors are vulnerable to a cross-thread return address
  predictions bug. When running in SMT mode and one of the sibling
  threads transitions out of C0 state, the other thread gets access to
  twice as many entries in the RSB, but unfortunately the predictions of
  the now-halted logical processor are not purged. Therefore, the
  executing processor could speculatively execute from locations that
  the now-halted processor had trained the RSB on.

  The Spectre v2 mitigations cover the Linux kernel, as it fills the RSB
  when context switching to the idle thread. However, KVM allows a VMM
  to prevent exiting guest mode when transitioning out of C0 using the
  KVM_CAP_X86_DISABLE_EXITS capability can be used by a VMM to change
  this behavior. To mitigate the cross-thread return address predictions
  bug, a VMM must not be allowed to override the default behavior to
  intercept C0 transitions.

  These patches introduce a KVM module parameter that, if set, will
  prevent the user from disabling the HLT, MWAIT and CSTATE exits"
