9e1e9d6602 Merge tag 'trace-rtla-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace 
Pull RTLA updates from Steven Rostedt:

 - Simplify option parsing

   Auto-generate getopt_long() optstring for short options from long
   options array, avoiding the need to specify it manually and reducing
   the surface for mistakes.

 - Add unit tests

   Implement unit tests (make unit-tests) using libcheck, next to
   existing runtime tests (make check). Currently, three functions from
   utils.c are tested.

 - Add --stack-format option

   In addition to stopping stack pointer decoding (with -s/--stack
   option) on first unresolvable pointer, allow also skipping
   unresolvable pointers and displaying everything, configurable with a
   new option.

 - Unify number of CPUs into one global variable

   Use one global variable, nr_cpus, to store the number of CPUs instead
   of retrieving it and passing it at multiple places.

 - Fix behavior in various corner cases

   Make RTLA behave correctly in several corner cases: memory allocation
   failure, invalid value read from kernel side, thread creation
   failure, malformed time value input, and read/write failure or
   interruption by signal.

 - Improve string handling

   Simplify several places in the code that handle strings, including
   parsing of action arguments. A few new helper functions and variables
   are added for that purpose.

 - Get rid of magic numbers

   Few places handling paths use a magic number of 1024. Replace it with
   MAX_PATH and ARRAY_SIZE() macro.

 - Unify threshold handling

   Code that handles response to latency threshold is duplicated between
   tools, which has led to bugs in the past. Unify it into a new helper
   as much as possible.

 - Fix segfault on SIGINT during cleanup

   The SIGINT handler touches dynamically allocated memory. Detach it
   before freeing it during cleanup to prevent segmentation fault and
   discarding of output buffers. Also, properly document SIGINT handling
   while at it.

Pull runtime verification updates from Steven Rostedt:

 - Refactor da_monitor header to share handlers across monitor types

   No functional changes, only less code duplication.

 - Add Hybrid Automata model class

   Add a new model class that extends deterministic automata by adding
   constraints on transitions and states. Those constraints can take
   into account wall-clock time and as such allow RV monitor to make
   assertions on real time. Add documentation and code generation
   scripts.

 - Add stall monitor as hybrid automaton example

   Add a monitor that triggers a violation when a task is stalling as an
   example of automaton working with real time variables.

 - Convert the opid monitor to a hybrid automaton

   The opid monitor can be heavily simplified if written as a hybrid
   automaton: instead of tracking preempt and interrupt enable/disable
   events, it can just run constraints on the preemption/interrupt
   states when events like wakeup and need_resched verify.

 - Add support for per-object monitors in DA/HA

   Allow writing deterministic and hybrid automata monitors for generic
   objects (e.g. any struct), by exploiting a hash table where objects
   are saved. This allows to track more than just tasks in RV. For
   instance it will be used to track deadline entities in deadline
   monitors.

 - Add deadline tracepoints and move some deadline utilities

   Prepare the ground for deadline monitors by defining events and
   exporting helpers.

 - Add nomiss deadline monitor

   Add first example of deadline monitor asserting all entities complete
   before their deadline.

 - Improve rvgen error handling

   Introduce AutomataError exception class and better handle expected
   exceptions while showing a backtrace for unexpected ones.

 - Improve python code quality in rvgen

   Refactor the rvgen generation scripts to align with python best
   practices: use f-strings instead of %, use len() instead of
   __len__(), remove semicolons, use context managers for file
   operations, fix whitespace violations, extract magic strings into
   constants, remove unused imports and methods.

 - Fix small bugs in rvgen

   The generator scripts presented some corner case bugs: logical error
   in validating what a correct dot file looks like, fix an isinstance()
   check, enforce a dot file has an initial state, fix type annotations
   and typos in comments.

 - rvgen refactoring

   Refactor automata.py to use iterator-based parsing and handle
   required arguments directly in argparse.

 - Allow epoll in rtapp-sleep monitor

   The epoll_wait call is now rt-friendly so it should be allowed in the
   sleep monitor as a valid sleep method.

e4bf304f00 Merge tag 'trace-ringbuffer-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace 
Pull ring-buffer updates from Steven Rostedt:

 - Add remote buffers for pKVM

   pKVM has a hypervisor component that is used to protect the guest
   from the host kernel. This hypervisor is a black box to the kernel as
   the kernel is to user space. The remote buffers are used to have a
   memory mapping between the hypervisor and the kernel where kernel may
   send commands to enable tracing within the hypervisor. Then the
   kernel will read this memory mapping just like user space can read
   the memory mapped ring buffer of the kernel tracing system.

   Since the hypervisor only has a single context, it doesn't need to
   worry about races between normal context, interrupt context and NMIs
   like the kernel does. The ring buffer it uses doesn't need to be as
   complex. The remote buffers are a simple version of the ring buffer
   that works in a single context. They are still per-CPU and use sub
   buffers. The data layout is the same as the kernel's ring buffer to
   share the same parsing.

   Currently, only ARM64 implements pKVM, but there's work to implement
   it also in x86. The remote buffer code is separated out from the ARM
   implementation so that it can be used in the future by x86.

   The ARM64 updates for pKVM is in the ARM/KVM tree and it merged in
   the remote buffers of this tree.

 - Make the backup instance non reusable

   The backup instance is a copy of the persistent ring buffer so that
   the persistent ring buffer could start recording again without using
   the data from the previous boot. The backup isn't for normal tracing.
   It is made read-only, and after it is consumed, it is automatically
   removed.

 - Have backup copy persistent instance before it starts recording

   To allow the persistent ring buffer to start recording from the
   kernel command line commands, move the copy of the backup instance to
   before the the command line options start recording.

 - Report header_page overwrite field as "char" and not "int'

   The rust parser of the header_page file was triggering a warning when
   it defined the overwrite variable as "int" but it was only a single
   byte in size.

 - Fix memory barriers for the trace_buffer CPU mask

   When a CPU comes online, the bit is set to allow readers to know that
   the CPU buffer is allocated. The bit is set after the allocation is
   done, and a smp_wmb() is performed after the allocation and before
   the setting of the bit. But instead of adding a smp_rmb() to all
   readers, since once a buffer is created for a CPU it is not deleted
   if that CPU goes offline, so this allocation is almost always done at
   boot up before any readers exist.

   If for the unlikely case where a CPU comes online for the first time
   after the system boot has finished, send an IPI to all CPUs to force
   the smp_rmb() for each CPU.

 - Show clock function being used in debugging ring buffer data

   When the ring buffer checks are enabled and the ring buffer detects
   an inconsistency in the times of the invents, print out the clock
   being used when the error occurred. There was a very hard to hit bug
   that would happen every so often and it ended up being only triggered
   when the jiffies clock was being used. If the bug showed the clock
   being used, it would have been much easier to find the problem (which
   was an internal function was being traced which caused the clock
   accounting to go off).

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Allow TLP Processing Hints to be enabled for RCiEPs (George Abraham
     P)

   - Enable AtomicOps only if we know the Root Port supports them (Gerd
     Bayer)

   - Don't enable AtomicOps for RCiEPs since none of them need Atomic
     Ops and we can't tell whether the Root Complex would support them
     (Gerd Bayer)

   - Leave Precision Time Measurement disabled until a driver enables it
     to avoid PCIe errors (Mika Westerberg)

   - Make pci_set_vga_state() fail if bridge doesn't support VGA
     routing, i.e., PCI_BRIDGE_CTL_VGA is not writable, and return
     errors to vga_get() callers including userspace via
     /dev/vga_arbiter (Simon Richter)

   - Validate max-link-speed from DT in j721e, brcmstb, mediatek-gen3,
     rzg3s drivers (where the actual controller constraints are known),
     and remove validation from the generic OF DT accessor (Hans Zhang)

   - Remove pc110pad driver (no longer useful after 486 CPU support
     removed) and no_pci_devices() (pc110pad was the last user) (Dmitry
     Torokhov, Heiner Kallweit)

  Resource management:

   - Prevent assigning space to unimplemented bridge windows; previously
     we mistakenly assumed prefetchable window existed and assigned
     space and put a BAR there (Ahmed Naseef)

   - Avoid shrinking bridge windows to fit in the initial Root Port
     window; fixes one problem with devices with large BARs connected
     via switches, e.g., Thunderbolt (Ilpo Järvinen)

   - Pass full extent of empty space, not just the aligned space, to
     resource_alignf callback so free space before the requested
     alignment can be used (Ilpo Järvinen)

   - Place small resources before larger ones for better utilization of
     address space (Ilpo Järvinen)

   - Fix alignment calculation for resource size larger than align,
     e.g., bridge windows larger than the 1MB required alignment (Ilpo
     Järvinen)

  Reset:

   - Update slot handling so all ARI functions are treated as being in
     the same slot. They're all reset by Secondary Bus Reset, but
     previously drivers of ARI functions that appeared to be on a
     non-zero device weren't notified and fatal hardware errors could
     result (Keith Busch)

   - Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug
     events (Keith Busch)

   - Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked
     by CXL because it has no effect (Vidya Sagar)

   - Avoid FLR for AMD NPU device, where it causes the device to hang
     (Lizhi Hou)

  Error handling:

   - Clear only error bits in PCIe Device Status to avoid accidentally
     clearing Emergency Power Reduction Detected (Shuai Xue)

   - Check for AER errors even in devices without drivers (Lukas Wunner)

   - Initialize ratelimit info so DPC and EDR paths log AER error
     information (Kuppuswamy Sathyanarayanan)

  Power control:

   - Add UPD720201/UPD720202 USB 3.0 xHCI Host Controller .compatible so
     generic pwrctrl driver can control it (Neil Armstrong)

  Hotplug:

   - Set LED_HW_PLUGGABLE for NPEM hotplug-capable ports so LED core
     doesn't complain when setting brightness fails because the endpoint
     is gone (Richard Cheng)

  Peer-to-peer DMA:

   - Allow wildcards in list of host bridges that support peer-to-peer
     DMA between hierarchy domains and add all Google SoCs (Jacob
     Moroni)

  Endpoint framework:

   - Advertise dynamic inbound mapping support in pci-epf-test and
     update host pci_endpoint_test to skip doorbell testing if not
     advertised by endpoint (Koichiro Den)

   - Return 0, not remaining timeout, when MHI eDMA ops complete so
     mhi_ep_ring_add_element() doesn't interpret non-zero as failure
     (Daniel Hodges)

   - Remove vntb and ntb duplicate resource teardown that leads to oops
     when .allow_link() fails or .drop_link() is called (Koichiro Den)

   - Disable vntb delayed work before clearing BAR mappings and

5bdb4078e1 Merge tag 'sched_ext-for-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext 
Pull sched_ext updates from Tejun Heo:

 - cgroup sub-scheduler groundwork

   Multiple BPF schedulers can be attached to cgroups and the dispatch
   path is made hierarchical. This involves substantial restructuring of
   the core dispatch, bypass, watchdog, and dump paths to be
   per-scheduler, along with new infrastructure for scheduler ownership
   enforcement, lifecycle management, and cgroup subtree iteration

   The enqueue path is not yet updated and will follow in a later cycle

 - scx_bpf_dsq_reenq() generalized to support any DSQ including remote
   local DSQs and user DSQs

   Built on top of this, SCX_ENQ_IMMED guarantees that tasks dispatched
   to local DSQs either run immediately or get reenqueued back through
   ops.enqueue(), giving schedulers tighter control over queueing
   latency

   Also useful for opportunistic CPU sharing across sub-schedulers

 - ops.dequeue() was only invoked when the core knew a task was in BPF
   data structures, missing scheduling property change events and
   skipping callbacks for non-local DSQ dispatches from ops.select_cpu()

   Fixed to guarantee exactly one ops.dequeue() call when a task leaves
   BPF scheduler custody

 - Kfunc access validation moved from runtime to BPF verifier time,
   removing runtime mask enforcement

 - Idle SMT sibling prioritization in the idle CPU selection path

 - Documentation, selftest, and tooling updates. Misc bug fixes and
   cleanups

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

   - Support HW queue leasing, allowing containers to be granted access
     to HW queues for zero-copy operations and AF_XDP

   - Number of code moves to help the compiler with inlining. Avoid
     output arguments for returning drop reason where possible

   - Rework drop handling within qdiscs to include more metadata about
     the reason and dropping qdisc in the tracepoints

   - Remove the rtnl_lock use from IP Multicast Routing

   - Pack size information into the Rx Flow Steering table pointer
     itself. This allows making the table itself a flat array of u32s,
     thus making the table allocation size a power of two

   - Report TCP delayed ack timer information via socket diag

   - Add ip_local_port_step_width sysctl to allow distributing the
     randomly selected ports more evenly throughout the allowed space

   - Add support for per-route tunsrc in IPv6 segment routing

   - Start work of switching sockopt handling to iov_iter

   - Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
     buffer size drifting up

   - Support MSG_EOR in MPTCP

   - Add stp_mode attribute to the bridge driver for STP mode selection.
     This addresses concerns about call_usermodehelper() usage

   - Remove UDP-Lite support (as announced in 2023)

   - Remove support for building IPv6 as a module. Remove the now
     unnecessary function calling indirection

  Cross-tree stuff:

   - Move Michael MIC code from generic crypto into wireless, it's
     considered insecure but some WiFi networks still need it

  Netfilter:

   - Switch nft_fib_ipv6 module to no longer need temporary dst_entry
     object allocations by using fib6_lookup() + RCU.

     Florian W reports this gets us ~13% higher packet rate

   - Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
     switch the service tables to be per-net. Convert some code that
     walks the service lists to use RCU instead of the service_mutex

   - Add more opinionated input validation to lower security exposure

   - Make IPVS hash tables to be per-netns and resizable

  Wireless:

   - Finished assoc frame encryption/EPPKE/802.1X-over-auth

   - Radar detection improvements

   - Add 6 GHz incumbent signal detection APIs

   - Multi-link support for FILS, probe response templates and client
     probing

   - New APIs and mac80211 support for NAN (Neighbor Aware Networking,
     aka Wi-Fi Aware) so less work must be in firmware

  Driver API:

   - Add numerical ID for devlink instances (to avoid having to create
     fake bus/device pairs just to have an ID). Support shared devlink
     instances which span multiple PFs

   - Add standard counters for reporting pause storm events (implement
     in mlx5 and fbnic)

   - Add configuration API for completion writeback buffering (implement
     in mana)

   - Support driver-initiated change of RSS context sizes

   - Support DPLL monitoring input frequency (implement in zl3073x)

   - Support per-port resources in devlink (implement in mlx5)

 - Welcome new BPF maintainers: Kumar Kartikeya Dwivedi, Eduard
   Zingerman while Martin KaFai Lau reduced his load to Reviwer.

 - Lots of fixes everywhere from many first time contributors. Thank you
   All.

 - Diff stat is dominated by mechanical split of verifier.c into
   multiple components:

    - backtrack.c: backtracking logic and jump history
    - states.c:    state equivalence
    - cfg.c:       control flow graph, postorder, strongly connected
                   components
    - liveness.c:  register and stack liveness
    - fixups.c:    post-verification passes: instruction patching, dead
                   code removal, bpf_loop inlining, finalize fastcall

   8k line were moved. verifier.c still stands at 20k lines.

   Further refactoring is planned for the next release.

 - Replace dynamic stack liveness with static stack liveness based on
   data flow analysis.

   This improved the verification time by 2x for some programs and
   equally reduced memory consumption. New logic is in liveness.c and
   supported by constant folding in const_fold.c (Eduard Zingerman,
   Alexei Starovoitov)

 - Further extend support for implicit arguments in the verifier (Ihor
   Solodrai)

 - Add support for nop,nop5 instruction combo for USDT probes in libbpf
   (Jiri Olsa)

 - Support merging multiple module BTFs (Josef Bacik)

 - Extend applicability of bpf_kptr_xchg (Kaitao Cheng)

 - Retire rcu_trace_implies_rcu_gp() (Kumar Kartikeya Dwivedi)

Pull module updates from Sami Tolvanen:
 "Kernel symbol flags:

   - Replace the separate *_gpl symbol sections (__ksymtab_gpl and
     __kcrctab_gpl) with a unified symbol table and a new __kflagstab
     section.

     This section stores symbol flags, such as the GPL-only flag, as an
     8-bit bitset for each exported symbol. This is a cleanup that
     simplifies symbol lookup in the module loader by avoiding table
     fragmentation and will allow a cleaner way to add more flags later
     if needed.

  Module signature UAPI:

   - Move struct module_signature to the UAPI headers to allow reuse by
     tools outside the kernel proper, such as kmod and
     scripts/sign-file.

     This also renames a few constants for clarity and drops unused
     signature types as preparation for hash-based module integrity
     checking work that's in progress.

  Sysfs:

   - Add a /sys/module/<module>/import_ns sysfs attribute to show the
     symbol namespaces imported by loaded modules.

     This makes it easier to verify driver API access at runtime on
     systems that care about such things (e.g. Android).

  Cleanups and fixes:

   - Force sh_addr to 0 for all sections in module.lds. This prevents
     non-zero section addresses when linking modules with 'ld.bfd -r',
     which confused elfutils.

   - Fix a memory leak of charp module parameters on module unload when
     the kernel is configured with CONFIG_SYSFS=n.

   - Override the -EEXIST error code returned by module_init() to
     userspace. This prevents confusion with the errno reserved by the
     module loader to indicate that a module is already loaded.

   - Simplify the warning message and drop the stack dump on positive
     returns from module_init().

   - Drop unnecessary extern keywords from function declarations and
     synchronize parse_args() arguments with their implementation"

Pull arm64 updates from Catalin Marinas:
 "The biggest changes are MPAM enablement in drivers/resctrl and new PMU
  support under drivers/perf.

  On the core side, FEAT_LSUI lets futex atomic operations with EL0
  permissions, avoiding PAN toggling.

  The rest is mostly TLB invalidation refactoring, further generic entry
  work, sysreg updates and a few fixes.

  Core features:

   - Add support for FEAT_LSUI, allowing futex atomic operations without
     toggling Privileged Access Never (PAN)

   - Further refactor the arm64 exception handling code towards the
     generic entry infrastructure

   - Optimise __READ_ONCE() with CONFIG_LTO=y and allow alias analysis
     through it

  Memory management:

   - Refactor the arm64 TLB invalidation API and implementation for
     better control over barrier placement and level-hinted invalidation

   - Enable batched TLB flushes during memory hot-unplug

   - Fix rodata=full block mapping support for realm guests (when
     BBML2_NOABORT is available)

  Perf and PMU:

   - Add support for a whole bunch of system PMUs featured in NVIDIA's
     Tegra410 SoC (cspmu extensions for the fabric and PCIe, new drivers
     for CPU/C2C memory latency PMUs)

   - Clean up iomem resource handling in the Arm CMN driver

   - Fix signedness handling of AA64DFR0.{PMUVer,PerfMon}

  MPAM (Memory Partitioning And Monitoring):

   - Add architecture context-switch and hiding of the feature from KVM

   - Add interface to allow MPAM to be exposed to user-space using
     resctrl

   - Add errata workaround for some existing platforms

   - Add documentation for using MPAM and what shape of platforms can
     use resctrl

  Miscellaneous:

   - Check DAIF (and PMR, where relevant) at task-switch time

   - Skip TFSR_EL1 checks and barriers in synchronous MTE tag check mode
     (only relevant to asynchronous or asymmetric tag check modes)

   - Remove a duplicate allocation in the kexec code

   - Remove redundant save/restore of SCS SP on entry to/from EL0

   - Generate the KERNEL_HWCAP_ definitions from the arm64 hwcap
     descriptions

   - Add kselftest coverage for cmpbr_sigill()

   - Update sysreg definitions"

Pull timer core updates from Thomas Gleixner:

 - A rework of the hrtimer subsystem to reduce the overhead for
   frequently armed timers, especially the hrtick scheduler timer:

     - Better timer locality decision

     - Simplification of the evaluation of the first expiry time by
       keeping track of the neighbor timers in the RB-tree by providing
       a RB-tree variant with neighbor links. That avoids walking the
       RB-tree on removal to find the next expiry time, but even more
       important allows to quickly evaluate whether a timer which is
       rearmed changes the position in the RB-tree with the modified
       expiry time or not. If not, the dequeue/enqueue sequence which
       both can end up in rebalancing can be completely avoided.

     - Deferred reprogramming of the underlying clock event device. This
       optimizes for the situation where a hrtimer callback sets the
       need resched bit. In that case the code attempts to defer the
       re-programming of the clock event device up to the point where
       the scheduler has picked the next task and has the next hrtick
       timer armed. In case that there is no immediate reschedule or
       soft interrupts have to be handled before reaching the reschedule
       point in the interrupt entry code the clock event is reprogrammed
       in one of those code paths to prevent that the timer becomes
       stale.

     - Support for clocksource coupled clockevents

       The TSC deadline timer is coupled to the TSC. The next event is
       programmed in TSC time. Currently this is done by converting the
       CLOCK_MONOTONIC based expiry value into a relative timeout,
       converting it into TSC ticks, reading the TSC adding the delta
       ticks and writing the deadline MSR.

       As the timekeeping core has the conversion factors for the TSC
       already, the whole back and forth conversion can be completely
       avoided. The timekeeping core calculates the reverse conversion
       factors from nanoseconds to TSC ticks and utilizes the base
       timestamps of TSC and CLOCK_MONOTONIC which are updated once per
       tick. This allows a direct conversion into the TSC deadline value
       without reading the time and as a bonus keeps the deadline
       conversion in sync with the TSC conversion factors, which are
       updated by adjtimex() on systems with NTP/PTP enabled.

     - Allow inlining of the clocksource read and clockevent write
       functions when they are tiny enough, e.g. on x86 RDTSC and WRMSR.

   With all those enhancements in place a hrtick enabled scheduler
   provides the same performance as without hrtick. But also other
   hrtimer users obviously benefit from these optimizations.

 - Robustness improvements and cleanups of historical sins in the
   hrtimer and timekeeping code.

 - Rewrite of the clocksource watchdog.

   The clocksource watchdog code has over time reached the state of an
   impenetrable maze of duct tape and staples. The original design,
   which was made in the context of systems far smaller than today, is
   based on the assumption that the to be monitored clocksource (TSC)
   can be trivially compared against a known to be stable clocksource
   (HPET/ACPI-PM timer).

   Over the years this rather naive approach turned out to have major
   flaws. Long delays between the watchdog invocations can cause wrap
   arounds of the reference clocksource. The access to the reference
   clocksource degrades on large multi-sockets systems dure to
   interconnect congestion. This has been addressed with various
   heuristics which degraded the accuracy of the watchdog to the point
   that it fails to detect actual TSC problems on older hardware which
   exposes slow inter CPU drifts due to firmware manipulating the TSC to
   hide SMI time.

   The rewrite addresses this by:

     - Restricting the validation against the reference clocksource to
       the boot CPU which is usually closest to the legacy block which
       contains the reference clocksource (HPET/ACPI-PM).

     - Do a round robin validation betwen the boot CPU and the other
       CPUs based only on the TSC with an algorithm similar to the TSC
       synchronization code during CPU hotplug.

     - Being more leniant versus remote timeouts

 - The usual tiny fixes, cleanups and enhancements all over the place

Pull gpio updates from Bartosz Golaszewski:
 "For this merge window we have two new drivers: support for
  GPIO-signalled ACPI events on Intel platforms and a generic
  GPIO-over-pinctrl driver using the ARM SCMI protocol for
  controlling pins.

  Several things have been reworked in GPIO core: we unduplicated GPIO
  hog handling, reduced the number of SRCU locks and dereferences,
  improved support for software-node-based lookup and removed more
  legacy code after converting remaining users to modern alternatives.

  There's also a number of driver reworks and refactoring, documentation
  updates, some bug-fixes and new tests.

  GPIO core:
   - defer probe on software node lookups when the remote software node
     exists but has not been registered as a firmware node yet
   - unify GPIO hog handling by moving code duplicated in OF and ACPI
     modules into GPIO core and allow setting up hogs with software
     nodes
   - allow matching GPIO controllers by secondary firmware node if
     matching by primary does not succeed
   - demote deferral warnings to debug level as they are quite normal
     when using software nodes which don't support fw_devlink yet
   - disable the legacy GPIO character device uAPI v1 supprt in Kconfig
     by default
   - rework several core functions in preparation for the upcoming
     Revocable helper library for protecting resources against sudden
     removal, this reduces the number of SRCU dereferences in GPIO core
   - simplify file descriptor logic in GPIO character device code by
     using FD_PREPARE()
   - introduce a header defining symbols used by both GPIO consumers and
     providers to avoid having to include provider-specific headers from
     drivers which only consume GPIOs
   - replace snprintf() with strscpy() where formatting is not required

  New drivers:
   - add the gpio-by-pinctrl generic driver using the ARM SCMI protocol
     to control GPIOs (along with SCMI changes pulled from the pinctrl
     tree)
   - add a driver providing support for handling of platform events via
     GPIO-signalled ACPI events (used on Intel Nova Lake and later
     platforms)

  Driver changes:
   - extend the gpio-kempld driver with support for more recent models,
     interrupts and setting/getting multiple values at once
   - improve interrupt handling in gpio-brcmstb
   - add support for multi-SoC systems in gpio-tegra186
   - make sure we return correct values from the .get() callbacks in
     several GPIO drivers by normalizing any values other than 0, 1 or
     negative error numbers
   - use flexible arrays in several drivers to reduce the number of
     required memory allocations
   - simplify synchronous waiting for virtual drivers to probe and
     remove the dedicated, a bit overengineered helper library
     dev-sync-probe
   - remove unneeded Kconfig dependencies on OF_GPIO in several drivers
     and subsystems
   - convert the two remaining users of of_get_named_gpio() to using
     GPIO descriptors and remove the (no longer used) function along
     with the header that declares it
   - add missing includes in gpio-mmio
   - shrink and simplify code in gpio-max732x by using guard(mutex)
   - remove duplicated code handling the 'ngpios' property from
     gpio-ts4800, it's already handled in GPIO core
   - use correct variable type in gpio-aspeed
   - add support for a new model in gpio-realtek-otto
   - allow to specify the active-low setting of simulated hogs over the
     configfs interface (in addition to existing devicetree support) in
     gpio-sim

  Bug fixes:
   - clear the OF_POPULATED flag on hog nodes in GPIO chip remove path
     on OF systems
   - fix resource leaks in error path in gpiochip_add_data_with_key()
   - drop redundant device reference in gpio-mpsse

  Tests:
   - add selftests for use-after-free cases in GPIO character device
     code

  DT bindings:
   - add a DT binding document for SCMI based, gpio-over-pinctrl devices
   - fix interrupt description in microchip,mpfs-gpio
   - add new compatible for gpio-realtek-otto
   - describe the resets of the mpfs-gpio controller
   - fix maintainer's email in gpio-delay bindings
   - remove the binding document for cavium,thunder-8890 as the
     corresponding device is bound over PCI and not firmware nodes

  Documentation:
   - update the recommended way of converting legacy boards to using
     software nodes for GPIO description
   - describe GPIO line value semantics
   - misc updates to kerneldocs

  Misc:
   - convert OMAP1 ams-delta board to using GPIO hogs described with

Pull power management updates from Rafael Wysocki:
 "Once again, cpufreq is the most active development area, mostly
  because of the new feature additions and documentation updates in the
  amd-pstate driver, but there are also changes in the cpufreq core
  related to boost support and other assorted updates elsewhere.

  Next up are power capping changes due to the major cleanup of the
  Intel RAPL driver.

  On the cpuidle front, a new C-states table for Intel Panther Lake is
  added to the intel_idle driver, the stopped tick handling in the menu
  and teo governors is updated, and there are a couple of cleanups.

  Apart from the above, support for Tegra114 is added to devfreq and
  there are assorted cleanups of that code, there are also two updates
  of the operating performance points (OPP) library, two minor updates
  related to hibernation, and cpupower utility man pages updates and
  cleanups.

  Specifics:

   - Update qcom-hw DT bindings to include Eliza hardware (Abel Vesa)

   - Update cpufreq-dt-platdev blocklist (Faruque Ansari)

   - Minor updates to driver and dt-bindings for Tegra (Thierry Reding,
     Rosen Penev)

   - Add MAINTAINERS entry for CPPC driver (Viresh Kumar)

   - Add support for new features: CPPC performance priority, Dynamic
     EPP, Raw EPP, and new unit tests for them to amd-pstate (Gautham
     Shenoy, Mario Limonciello)

   - Fix sysfs files being present when HW missing and broken/outdated
     documentation in the amd-pstate driver (Ninad Naik, Gautham Shenoy)

   - Pass the policy to cpufreq_driver->adjust_perf() to avoid using
     cpufreq_cpu_get() in the .adjust_perf() callback in amd-pstate
     which leads to a scheduling-while-atomic bug (K Prateek Nayak)

   - Clean up dead code in Kconfig for cpufreq (Julian Braha)

   - Remove max_freq_req update for pre-existing cpufreq policy and add
     a boost_freq_req QoS request to save the boost constraint instead
     of overwriting the last scaling_max_freq constraint (Pierre
     Gondois)

   - Embed cpufreq QoS freq_req objects in cpufreq policy so they all
     are allocated in one go along with the policy to simplify lifetime
     rules and avoid error handling issues (Viresh Kumar)

   - Use DMI max speed when CPPC is unavailable in the acpi-cpufreq
     scaling driver (Henry Tseng)

   - Switch policy_is_shared() in cpufreq to using cpumask_nth() instead
     of cpumask_weight() because the former is more efficient (Yury
     Norov)

   - Use sysfs_emit() in sysfs show functions for cpufreq governor
     attributes (Thorsten Blum)

   - Update intel_pstate to stop returning an error when "off" is
     written to its status sysfs attribute while the driver is already
     off (Fabio De Francesco)

   - Include current frequency in the debug message printed by
     __cpufreq_driver_target() (Pengjie Zhang)

   - Refine stopped tick handling in the menu cpuidle governor and
     rearrange stopped tick handling in the teo cpuidle governor (Rafael
     Wysocki)

   - Add Panther Lake C-states table to the intel_idle driver (Artem
     Bityutskiy)

   - Clean up dead dependencies on CPU_IDLE in Kconfig (Julian Braha)

   - Simplify cpuidle_register_device() with guard() (Huisong Li)

   - Use performance level if available to distinguish between rates in
     OPP debugfs (Manivannan Sadhasivam)

   - Fix scoped_guard in dev_pm_opp_xlate_required_opp() (Viresh Kumar)

   - Return -ENODATA if the snapshot image is not loaded (Alberto
     Garcia)

   - Remove inclusion of crypto/hash.h from hibernate_64.c on x86 (Eric
     Biggers)

   - Clean up and rearrange the intel_rapl power capping driver to make
     the respective interface drivers (TPMI, MSR, and MMOI) hold their
     own settings and primitives and consolidate PL4 and PMU support
     flags into rapl_defaults (Kuppuswamy Sathyanarayanan)

   - Correct kernel-doc function parameter names in the power capping
     core code (Randy Dunlap)

   - Remove unneeded casting for HZ_PER_KHZ in devfreq (Andy Shevchenko)

   - Use _visible attribute to replace create/remove_sysfs_files() in
     devfreq (Pengjie Zhang)

   - Add Tegra114 support to activity monitor device in tegra30-devfreq
     as a preparation to upcoming EMC controller support (Svyatoslav
     Ryhel)

   - Fix mistakes in cpupower man pages, add the boost and epp options
     to the cpupower-frequency-info man page, and add the perf-bias
     option to the cpupower-info man page (Roberto Ricci)

   - Remove unnecessary extern declarations from getopt.h in arguments
     parsing functions in cpufreq-set, cpuidle-info, cpuidle-set,
     cpupower-info, and cpupower-set utilities (Kaushlendra Kumar)"

Pull ACPI support updates from Rafael Wysocki:
 "These include an update of the CMOS RTC driver and the related ACPI
  and x86 code that, among other things, switches it over to using the
  platform device interface for device binding on x86 instead of the PNP
  device driver interface (which allows the code in question to be
  simplified quite a bit), a major update of the ACPI Time and Alarm
  Device (TAD) driver adding an RTC class device interface to it, and
  updates of core ACPI drivers that remove some unnecessary and not
  really useful code from them.

  Apart from that, two drivers are converted to using the platform
  driver interface for device binding instead of the ACPI driver one,
  which is slated for removal, support for the Performance Limited
  register is added to the ACPI CPPC library and there are some
  janitorial updates of it and the related cpufreq CPPC driver, the ACPI
  processor driver is fixed and cleaned up, and NVIDIA vendor CPER
  record handler is added to the APEI GHES code.

  Also, the interface for obtaining a CPU UID from ACPI is consolidated
  across architectures and used for fixing a problem with the PCI TPH
  Steering Tag on ARM64, there are two updates related to ACPICA, a
  minor ACPI OS Services Layer (OSL) update, and a few assorted updates
  related to ACPI tables parsing.

  Specifics:

   - Update maintainers information regarding ACPICA (Rafael Wysocki)

   - Replace strncpy() with strscpy_pad() in acpi_ut_safe_strncpy()
     (Kees Cook)

   - Trigger an ordered system power off after encountering a fatal
     error operator in AML (Armin Wolf)

   - Enable ACPI FPDT parsing on LoongArch (Xi Ruoyao)

   - Remove the temporary stop-gap acpi_pptt_cache_v1_full structure
     from the ACPI PPTT parser (Ben Horgan)

   - Add support for exposing ACPI FPDT subtables FBPT and S3PT (Nate
     DeSimone)

   - Address multiple assorted issues and clean up the code in the ACPI
     processor idle driver (Huisong Li)

   - Replace strlcat() in the ACPI processor idle drive with a better
     alternative (Andy Shevchenko)

   - Rearrange and clean up acpi_processor_errata_piix4() (Rafael
     Wysocki)

   - Move reference performance to capabilities and fix an uninitialized
     variable in the ACPI CPPC library (Pengjie Zhang)

   - Add support for the Performance Limited Register to the ACPI CPPC
     library (Sumit Gupta)

   - Add cppc_get_perf() API to read performance controls, extend
     cppc_set_epp_perf() for FFH/SystemMemory, and make the ACPI CPPC
     library warn on missing mandatory DESIRED_PERF register (Sumit
     Gupta)

   - Modify the cpufreq CPPC driver to update MIN_PERF/MAX_PERF in
     target callbacks to allow it to control performance bounds via
     standard scaling_min_freq and scaling_max_freq sysfs attributes and
     add sysfs documentation for the Performance Limited Register to it
     (Sumit Gupta)

   - Add ACPI support to the platform device interface in the CMOS RTC
     driver, make the ACPI core device enumeration code create a
     platform device for the CMOS RTC, and drop CMOS RTC PNP device
     support (Rafael Wysocki)

   - Consolidate the x86-specific CMOS RTC handling with the ACPI TAD
     driver and clean up the CMOS RTC ACPI address space handler (Rafael
     Wysocki)

   - Enable ACPI alarm in the CMOS RTC driver if advertised in ACPI FADT
     and allow that driver to work without a dedicated IRQ if the ACPI
     alarm is used (Rafael Wysocki)

   - Clean up the ACPI TAD driver in various ways and add an RTC class
     device interface, including both the RTC setting/reading and alarm
     timer support, to it (Rafael Wysocki)

   - Clean up the ACPI AC and ACPI PAD (processor aggregator device)
     drivers (Rafael Wysocki)

   - Rework checking for duplicate video bus devices and consolidate
     pnp.bus_id workarounds handling in the ACPI video bus driver
     (Rafael Wysocki)

   - Update the ACPI core device drivers to stop setting
     acpi_device_name() unnecessarily (Rafael Wysocki)

   - Rearrange code using acpi_device_class() in the ACPI core device
     drivers and update them to stop setting acpi_device_class()
     unnecessarily (Rafael Wysocki)

   - Define ACPI_AC_CLASS in one place (Rafael Wysocki)

   - Convert the ni903x_wdt watchdog driver and the xen ACPI PAD driver
     to bind to platform devices instead of ACPI devices (Rafael
     Wysocki)

   - Add devm_ghes_register_vendor_record_notifier(), use it in the PCI
     hisi driver, and Add NVIDIA vendor CPER record handler (Kai-Heng
     Feng)

   - Consolidate the interface for obtaining a CPU UID from ACPI across
     architectures and use it to address incorrect PCI TPH Steering Tag
     on ARM64 resulting from the invalid assumption that the ACPI
     Processor UID would always be the same as the corresponding logical
     CPU ID in Linux (Chengwen Feng)"

3383589700 Merge tag 'vfs-7.1-rc1.directory' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs 
Pull vfs directory updates from Christian Brauner:
 "Recently 'start_creating', 'start_removing', 'start_renaming' and
  related interfaces were added which combine the locking and the
  lookup.

  At that time many callers were changed to use the new interfaces.
  However there are still an assortment of places out side of the core
  vfs where the directory is locked explictly, whether with inode_lock()
  or lock_rename() or similar. These were missed in the first pass for
  an assortment of uninteresting reasons.

  This addresses the remaining places where explicit locking is used,
  and changes them to use the new interfaces, or otherwise removes the
  explicit locking.

  The biggest changes are in overlayfs. The other changes are quite
  simple, though maybe the cachefiles changes is the least simple of
  those"
