Pull x86 TDX updates from Dave Hansen:
 "Intel Trust Domain updates.

  The existing TDX code needs a _bit_ of metadata from the TDX module.
  But KVM is going to need a bunch more very shortly. Rework the
  interface with the TDX module to be more consistent and handle the new
  higher volume.

  The TDX module has added a few new features. The first is a promise
  not to clobber RBP under any circumstances. Basically the kernel now
  will refuse to use any modules that don't have this promise. Second,
  enable the new "REDUCE_VE" feature. This ensures that the TDX module
  will not send some silly virtualization exceptions that the guest had
  no good way to handle anyway.

   - Centralize global metadata infrastructure

   - Use new TDX module features for exception suppression and RBP
     clobbering"

 - A large and involved preparatory series to pave the way to add
   exception handling for relocate_kernel - which will be a debugging
   facility that has aided in the field to debug an exceptionally hard
   to debug early boot bug. Plus assorted cleanups and fixes that were
   discovered along the way, by David Woodhouse:

      - Clean up and document register use in relocate_kernel_64.S
      - Use named labels in swap_pages in relocate_kernel_64.S
      - Only swap pages for ::preserve_context mode
      - Allocate PGD for x86_64 transition page tables separately
      - Copy control page into place in machine_kexec_prepare()
      - Invoke copy of relocate_kernel() instead of the original
      - Move relocate_kernel to kernel .data section
      - Add data section to relocate_kernel
      - Drop page_list argument from relocate_kernel()
      - Eliminate writes through kernel mapping of relocate_kernel page
      - Clean up register usage in relocate_kernel()
      - Mark relocate_kernel page as ROX instead of RWX
      - Disable global pages before writing to control page
      - Ensure preserve_context flag is set on return to kernel
      - Use correct swap page in swap_pages function
      - Fix stack and handling of re-entry point for ::preserve_context
      - Mark machine_kexec() with __nocfi
      - Cope with relocate_kernel() not being at the start of the page
      - Use typedef for relocate_kernel_fn function prototype
      - Fix location of relocate_kernel with -ffunction-sections (fix by Nathan Chancellor)

 - A series to remove the last remaining absolute symbol references from
   .head.text, and enforce this at build time, by Ard Biesheuvel:

      - Avoid WARN()s and panic()s in early boot code
      - Don't hang but terminate on failure to remap SVSM CA
      - Determine VA/PA offset before entering C code
      - Avoid intentional absolute symbol references in .head.text
      - Disable UBSAN in early boot code
      - Move ENTRY_TEXT to the start of the image
      - Move .head.text into its own output section
      - Reject absolute references in .head.text

 - The above build-time enforcement uncovered a handful of bugs of
   essentially non-working code, and a wrokaround for a toolchain bug,
   fixed by Ard Biesheuvel as well:

      - Fix spurious undefined reference when CONFIG_X86_5LEVEL=n, on GCC-12
      - Disable UBSAN on SEV code that may execute very early
      - Disable ftrace branch profiling in SEV startup code

Pull perf-tools updates from Namhyung Kim:
 "There are a lot of changes in the perf tools in this cycle.

  build:

   - Use generic syscall table to generate syscall numbers on supported
     archs

   - This also enables to get rid of libaudit which was used for syscall
     numbers

   - Remove python2 support as it's deprecated for years

   - Fix issues on static build with libzstd

  perf record:

   - Intel-PT supports "aux-action" config term to pause or resume
     tracing in the aux-buffer. Users can start the intel_pt event as
     "started-paused" and configure other events to control the Intel-PT
     tracing:

         # perf record --kcore -e intel_pt/aux-action=start-paused/   \
             -e syscalls:sys_enter_newuname/aux-action=resume/        \
             -e syscalls:sys_exit_newuname/aux-action=pause/ -- uname

     This requires kernel support (which was added in v6.13)

  perf lock:

   - 'perf lock contention' command has an ability to symbolize locks in
     dynamically allocated objects using slab cache name when it runs
     with BPF. Those dynamic locks would have "&" prefix in the name to
     distinguish them from ordinary (static) locks

Pull trace fing buffer fix from Steven Rostedt:
 "Fix atomic64 operations on some architectures for the tracing ring
  buffer:

   - Have emulating atomic64 use arch_spin_locks instead of
     raw_spin_locks

     The tracing ring buffer events have a small timestamp that holds
     the delta between itself and the event before it. But this can be
     tricky to update when interrupts come in. It originally just set
     the deltas to zero for events that interrupted the adding of
     another event which made all the events in the interrupt have the
     same timestamp as the event it interrupted. This was not suitable
     for many tools, so it was eventually fixed. But that fix required
     adding an atomic64 cmpxchg on the timestamp in cases where an event
     was added while another event was in the process of being added.

     Originally, for 32 bit architectures, the manipulation of the 64
     bit timestamp was done by a structure that held multiple 32bit
     words to hold parts of the timestamp and a counter. But as updates
     to the ring buffer were done, maintaining this became too complex
     and was replaced by the atomic64 generic operations which are now
     used by both 64bit and 32bit architectures. Shortly after that, it
     was reported that riscv32 and other 32 bit architectures that just
     used the generic atomic64 were locking up. This was because the
     generic atomic64 operations defined in lib/atomic64.c uses a
     raw_spin_lock() to emulate an atomic64 operation. The problem here
     was that raw_spin_lock() can also be traced by the function tracer
     (which is commonly used for debugging raw spin locks). Since the
     function tracer uses the tracing ring buffer, which now is being
     traced internally, this was triggering a recursion and setting off
     a warning that the spin locks were recusing.

     There's no reason for the code that emulates atomic64 operations to
     be using raw_spin_locks which have a lot of debugging
     infrastructure attached to them (depending on the config options).
     Instead it should be using the arch_spin_lock() which does not have
     any infrastructure attached to them and is used by low level
     infrastructure like RCU locks, lockdep and of course tracing. Using
     arch_spin_lock()s fixes this issue.

   - Do not trace in NMI if the architecture uses emulated atomic64
     operations

     Another issue with using the emulated atomic64 operations that uses
     spin locks to emulate the atomic64 operations is that they cannot
     be used in NMI context. As an NMI can trigger while holding the
     atomic64 spin locks it can try to take the same lock and cause a
     deadlock.

     Have the ring buffer fail recording events if in NMI context and
     the architecture uses the emulated atomic64 operations"

Pull tracing updates from Steven Rostedt:

 - Cleanup with guard() and free() helpers

   There were several places in the code that had a lot of "goto out" in
   the error paths to either unlock a lock or free some memory that was
   allocated. But this is error prone. Convert the code over to use the
   guard() and free() helpers that let the compiler unlock locks or free
   memory when the function exits.

 - Update the Rust tracepoint code to use the C code too

   There was some duplication of the tracepoint code for Rust that did
   the same logic as the C code. Add a helper that makes it possible for
   both algorithms to use the same logic in one place.

 - Add poll to trace event hist files

   It is useful to know when an event is triggered, or even with some
   filtering. Since hist files of events get updated when active and the
   event is triggered, allow applications to poll the hist file and wake
   up when an event is triggered. This will let the application know
   that the event it is waiting for happened.

 - Add :mod: command to enable events for current or future modules

   The function tracer already has a way to enable functions to be
   traced in modules by writing ":mod:<module>" into set_ftrace_filter.
   That will enable either all the functions for the module if it is
   loaded, or if it is not, it will cache that command, and when the
   module is loaded that matches <module>, its functions will be
   enabled. This also allows init functions to be traced. But currently
   events do not have that feature.

   Add the command where if ':mod:<module>' is written into set_event,
   then either all the modules events are enabled if it is loaded, or
   cache it so that the module's events are enabled when it is loaded.
   This also works from the kernel command line, where
   "trace_event=:mod:<module>", when the module is loaded at boot up,
   its events will be enabled then.

Pull fsnotify pre-content notification support from Jan Kara:
 "This introduces a new fsnotify event (FS_PRE_ACCESS) that gets
  generated before a file contents is accessed.

  The event is synchronous so if there is listener for this event, the
  kernel waits for reply. On success the execution continues as usual,
  on failure we propagate the error to userspace. This allows userspace
  to fill in file content on demand from slow storage. The context in
  which the events are generated has been picked so that we don't hold
  any locks and thus there's no risk of a deadlock for the userspace
  handler.

  The new pre-content event is available only for users with global
  CAP_SYS_ADMIN capability (similarly to other parts of fanotify
  functionality) and it is an administrator responsibility to make sure
  the userspace event handler doesn't do stupid stuff that can DoS the
  system.

  Based on your feedback from the last submission, fsnotify code has
  been improved and now file->f_mode encodes whether pre-content event
  needs to be generated for the file so the fast path when nobody wants
  pre-content event for the file just grows the additional file->f_mode
  check. As a bonus this also removes the checks whether the old
  FS_ACCESS event needs to be generated from the fast path. Also the
  place where the event is generated during page fault has been moved so
  now filemap_fault() generates the event if and only if there is no
  uptodate folio in the page cache.

  Also we have dropped FS_PRE_MODIFY event as current real-world users
  of the pre-content functionality don't really use it so let's start
  with the minimal useful feature set"

Pull bpf updates from Alexei Starovoitov:
 "A smaller than usual release cycle.

  The main changes are:

   - Prepare selftest to run with GCC-BPF backend (Ihor Solodrai)

     In addition to LLVM-BPF runs the BPF CI now runs GCC-BPF in compile
     only mode. Half of the tests are failing, since support for
     btf_decl_tag is still WIP, but this is a great milestone.

   - Convert various samples/bpf to selftests/bpf/test_progs format
     (Alexis Lothoré and Bastien Curutchet)

   - Teach verifier to recognize that array lookup with constant
     in-range index will always succeed (Daniel Xu)

   - Cleanup migrate disable scope in BPF maps (Hou Tao)

   - Fix bpf_timer destroy path in PREEMPT_RT (Hou Tao)

   - Always use bpf_mem_alloc in bpf_local_storage in PREEMPT_RT (Martin
     KaFai Lau)

   - Refactor verifier lock support (Kumar Kartikeya Dwivedi)

     This is a prerequisite for upcoming resilient spin lock.

   - Remove excessive 'may_goto +0' instructions in the verifier that
     LLVM leaves when unrolls the loops (Yonghong Song)

   - Remove unhelpful bpf_probe_write_user() warning message (Marco
     Elver)

   - Add fd_array_cnt attribute for prog_load command (Anton Protopopov)

6c8ad3ab45 atomic64: Use arch_spin_locks instead of raw_spin_locks
raw_spin_locks can be traced by lockdep or tracing itself. Atomic64
operations can be used in the tracing infrastructure. When an architecture
does not have true atomic64 operations it can use the generic version that
disables interrupts and uses spin_locks.

The tracing ring buffer code uses atomic64 operations for the time
keeping. But because some architectures use the default operations, the
locking inside the atomic operations can cause an infinite recursion.

As atomic64 implementation is architecture specific, it should not be
using raw_spin_locks() but instead arch_spin_locks as that is the purpose
of arch_spin_locks. To be used in architecture specific implementations of
generic infrastructure like atomic64 operations.

Note, by switching from raw_spin_locks to arch_spin_locks, the locks taken
to emulate the atomic64 operations will not have lockdep, mmio, or any
kind of checks done on them. They will not even disable preemption,
although the code will disable interrupts preventing the tasks that hold
the locks from being preempted. As the locks held are done so for very
short periods of time, and the logic is only done to emulate atomic64, not
having them be instrumented should not be an issue.

Pull ACPI updates from Rafael Wysocki:
 "The most significant change here is replacing msleep() in
  acpi_os_sleep() with usleep_range() to reduce spurious sleep time due
  to timer inaccuracy which may spectacularly reduce the duration of
  system suspend and resume transitions on some systems.

  All of the other changes fall into the fixes and cleanups category
  this time.

  Specifics:

   - Use usleep_range() instead of msleep() in acpi_os_sleep() to reduce
     excessive delays due to timer inaccuracy, mostly affecting system
     suspend and resume (Rafael Wysocki)

   - Use str_enabled_disabled() string helpers in the ACPI tables
     parsing code to make it easier to follow (Sunil V L)

   - Update device properties parsing on systems using ACPI so that data
     firmware nodes resulting from _DSD evaluation are treated as
     available in firmware nodes walks (Sakari Ailus)

   - Fix missing guid_t declaration in linux/prmt.h (Robert Richter)

   - Update the GHES handling code to follow the global panic= policy
     instead of overriding it by force-rebooting the system after a
     fatal HW error has been reported (Borislav Petkov)

   - Update messages printed by the ACPI battery driver to always refer
     to driver extensions as "hooks" to avoid confusion with similar
     functionality in the power supply subsystem in the future (Thomas
     Weißschuh)

   - Fix .probe() error path cleanup in the ACPI fan driver to avoid
     memory leaks (Joe Hattori)

   - Constify 'struct bin_attribute' in some places in the ACPI
     subsystem and mark it as __ro_after_init in one place to prevent
     binary blob attributes from being updated (Thomas Weißschuh)

   - Add empty stubs for several ACPI-related symbols so that they can
     be used when CONFIG_ACPI is unset and use them for removing
     unnecessary conditional compilation from the ipu-bridge driver
     (Ricardo Ribalda)"

Pull power management updates from Rafael Wysocki:
 "The majority of changes here are cpufreq updates which are dominated
  by amd-pstate driver changes, like in the previous cycle. Moreover,
  changes related to amd-pstate are also the majority of cpupower
  utility updates.

  Included are some pieces of new hardware support, like the addition of
  Clearwater Forest processors support to intel_idle, new cpufreq driver
  for Airoha SoCs, and Apple cpufreq driver extensions to support more
  SoCs. The intel_pstate driver is also extended to be able to support
  new platforms by using ACPI CPPC to compute scaling factors between
  HWP performance states and frequency.

  The rest is mostly fixes and cleanups in assorted pieces of power
  management code.

  Specifics:

   - Use str_enable_disable()-like helpers in cpufreq (Krzysztof
     Kozlowski)

   - Extend the Apple cpufreq driver to support more SoCs (Hector
     Martin, Nick Chan)

   - Add new cpufreq driver for Airoha SoCs (Christian Marangi)

   - Fix using cpufreq-dt as module (Andreas Kemnade)

   - Minor fixes for Sparc, SCMI, and Qcom cpufreq drivers (Ethan Carter
     Edwards, Sibi Sankar, Manivannan Sadhasivam)

   - Fix the maximum supported frequency computation in the ACPI cpufreq
     driver to avoid relying on unfounded assumptions (Gautham Shenoy)

   - Fix an amd-pstate driver regression with preferred core rankings
     not being used (Mario Limonciello)

   - Fix a precision issue with frequency calculation in the amd-pstate
     driver (Naresh Solanki)

   - Add ftrace event to the amd-pstate driver for active mode (Mario
     Limonciello)

   - Set default EPP policy on Ryzen processors in amd-pstate (Mario
     Limonciello)

   - Clean up the amd-pstate cpufreq driver and optimize it to increase
     code reuse (Mario Limonciello, Dhananjay Ugwekar)

   - Use CPPC to get scaling factors between HWP performance levels and
     frequency in the intel_pstate driver and make it stop using a
     built-in scaling factor for Arrow Lake processors (Rafael Wysocki)

   - Make intel_pstate initialize epp_policy to CPUFREQ_POLICY_UNKNOWN
     for consistency with CPU offline (Christian Loehle)

   - Fix superfluous updates caused by need_freq_update in the schedutil
     cpufreq governor (Sultan Alsawaf)

   - Allow configuring the system suspend-resume (DPM) watchdog to warn
     earlier than panic (Douglas Anderson)

   - Implement devm_device_init_wakeup() helper and introduce a device-
     managed variant of dev_pm_set_wake_irq() (Joe Hattori, Peng Fan)

   - Remove direct inclusions of 'pm_wakeup.h' which should be only
     included via 'device.h' (Wolfram Sang)

   - Clean up two comments in the core system-wide PM code (Rafael
     Wysocki, Randy Dunlap)

   - Add Clearwater Forest processor support to the intel_idle cpuidle
     driver (Artem Bityutskiy)

   - Clean up the Exynos devfreq driver and devfreq core (Markus
     Elfring, Jeongjun Park)

   - Minor cleanups and fixes for OPP (Dan Carpenter, Neil Armstrong,
     Joe Hattori)

   - Implement dev_pm_opp_get_bw() (Neil Armstrong)

   - Expose OPP reference counting helpers for Rust (Viresh Kumar)

   - Fix TSC MHz calculation in cpupower (He Rongguang)

   - Add install and uninstall options to bindings Makefile and add
     header changes for cpufreq.h to SWIG bindings in cpupower (John B.
     Wyatt IV)

   - Add missing residency header changes in cpuidle.h to SWIG bindings
     in cpupower (John B. Wyatt IV)

   - Add output files to .gitignore and clean them up in "make clean" in
     selftests/cpufreq (Li Zhijian)

   - Fix cross-compilation in cpupower Makefile (Peng Fan)

   - Revise the is_valid flag handling for idle_monitor in the cpupower
     utility (wangfushuai)

   - Extend and clean up AMD processors support in cpupower (Mario
     Limonciello)"
