Pull s390 updates from Vasily Gorbik:

 - Add a cpuidle driver with polling and enabled wait states using the
   existing CPU idle infrastructure and idle governor to improve latency
   for frequent sleep/wakeup cycles. Remove the obsolete tick delay
   heuristic and generic arch_needs_cpu() hook. Add the corresponding
   driver entry to MAINTAINERS

 - Add kCFI support using the generic support provided by Clang

 - Enable Clang CONTEXT_ANALYSIS for various architecture code and for
   char, PCI, CIO and virtio drivers. Add required lock annotations,
   exclude unsupported mm helpers and remove conditional PCI locking

 - Fix secure storage access exception handling and reintroduce
   DCACHE_WORD_ACCESS previously removed as a workaround

 - Fix cpum_cf perf crashes when CPUs are brought online while per-task
   events are active. Allocate and remove per-CPU counter data from CPU
   hotplug callbacks

 - Fix a deadlock when an s390dbf debug area is unregistered while one
   of its debugfs files is being written to

 - Fix MVIY_PERCPU() with binutils older than 2.39, where an assembler
   macro silently omitted an instruction needed to repair interrupted
   operations after CPU migration

 - Remove/replace cond_resched() calls which are no-ops with the
   supported s390 preemption models

 - Fix AP queue depth and maximum message length decoding according to
   the architecture. Current hardware is not affected, but future
   hardware could report values which were handled incorrectly

 - Reflect the configured CPU state in cpu_enabled_mask so deconfigured
   CPUs are not presented as available for onlining

 - Restore the vDSO GNU_EH_FRAME program header which was lost when the
   build switched to direct linker invocation, and mark it read-only

 - Add SCLP action qualifiers used by Spyre for card initialization,
   recoverable error and telemetry reporting

 - Move KMSAN interrupt flag helpers out of line to fix
   -Wstatic-in-inline build warnings

 - Use level-specific page table entry accessors for hugetlb entries and
   ptep_get() when accessing crashed kernel memory in kdump

 - Make forced AP bus rescans killable so that a user process blocked
   behind an ongoing scan can still be terminated with SIGKILL

 - Rework pkey ioctl error paths to remove duplicated cleanup code and
   avoid freeing error pointers

 - Allow the protected guest SWIOTLB buffer to be allocated outside the
   first 2GB. Also enable dynamic SWIOTLB growth and the coherent atomic
   pool fallback to improve I/O behavior when the initial pool is
   exhausted

 - Add program check statistics and spinlock contention tracepoints.
   Increase the lockdep chain capacity to keep lockdep enabled for
   complex code paths such as btrfs

 - Simplify IPL, trap and syscall code and remove the obsolete
   unistd_32.h generation entry

Move the DBx500 PRCMU definitions into the DB8500 PRCMU
header and delete the wrapper header.

Convert users of simple PRCMU wrappers to call the DB8500 helpers
directly.

The dbx500-prcmu.h header was the result of an earlier attempt to
abstract several DBx5x SoC PRCMU units to use the same abstract
header. They are deleted from the kernel and this is not just
causing maintenance burden and build errors.

The stub code is using -ENOSYS in a way checkpatch complains about
so replace these with -EINVAL while we're at it.

QCOM_SCM and QCOM_SPM are user-selectable drivers, thus
ARM_QCOM_SPM_CPUIDLE should rather avoid selecting them but instead
depend to avoid any possible unmet dependencies.

ARM_QCOM_SPM_CPUIDLE does use symbols from SCM and SPM, and since it
cannot be built-in, the dependency must be as built-in.

Introduce generic cpuidle driver on s390. Use a two stage approach to
handle idle scenarios and use idle governor for idle stage selection.
Two stages are, from shallow to deep, idle polling and enabled wait.

Commit 76934e495cdc ("cpuidle: Add sanity check for exit latency and
target residency") had added a check to prevent the exit latency of an
idle state from exceeding its target residency that later was limited to
printing a warning message in that case in commit 4bf944f3fcb6 ("cpuidle:
Warn instead of bailing out if target residency check fails").

However, a thorough code inspection with that in mind leads to the
conclusion that actually there are no assumptions in cpuidle regarding
the relationship between the exit latency and target residency of a
given idle state.  It is generally assumed that the idle states table
provided by a cpuidle driver will be sorted by both the target residency
and exit latency in ascending order, but that's a different matter.

Accordingly, drop the check in question along with the message printed
when it triggers and the inaccurate comment preceding it.

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)"

The cpuidle_unregister_device() function always acquires the internal
cpuidle_lock (or pause/resume idle) during their execution.

However, in some power notification scenarios (e.g., when old idle
states may become unavailable), it is necessary to efficiently disable
cpuidle first, then remove and re-create all cpuidle devices for all
CPUs. To avoid frequent lock overhead and ensure atomicity across the
entire batch operation, the caller needs to hold the cpuidle_lock once
outside the loop.

To address this, extract the core logic into the new function
cpuidle_unregister_device_no_lock() and export it.
