Pull VDSO updates from Thomas Gleixner:

 - Provide the missing 64-bit variant of clock_getres()

   This allows the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and
   finally the removal of 32-bit time types from the kernel and UAPI.

 - Remove the useless and broken getcpu_cache from the VDSO

   The intention was to provide a trivial way to retrieve the CPU number
   from the VDSO, but as the VDSO data is per process there is no way to
   make it work.

 - Switch get/put_unaligned() from packed struct to memcpy()

   The packed struct violates strict aliasing rules which requires to
   pass -fno-strict-aliasing to the compiler. As this are scalar values
   __builtin_memcpy() turns them into simple loads and stores

 - Use __typeof_unqual__() for __unqual_scalar_typeof()

   The get/put_unaligned() changes triggered a new sparse warning when
   __beNN types are used with get/put_unaligned() as sparse builds add a
   special 'bitwise' attribute to them which prevents sparse to evaluate
   the Generic in __unqual_scalar_typeof().

   Newer sparse versions support __typeof_unqual__() which avoids the
   problem, but requires a recent sparse install. So this adds a sanity
   check to sparse builds, which validates that sparse is available and
   capable of handling it.

 - Force inline __cvdso_clock_getres_common()

   Compilers sometimes un-inline agressively, which results in function
   call overhead and problems with automatic stack variable
   initialization.

   Interestingly enough the force inlining results in smaller code than
   the un-inlined variant produced by GCC when optimizing for size.

 "Lock debugging:

   - Implement compiler-driven static analysis locking context checking,
     using the upcoming Clang 22 compiler's context analysis features
     (Marco Elver)

     We removed Sparse context analysis support, because prior to
     removal even a defconfig kernel produced 1,700+ context tracking
     Sparse warnings, the overwhelming majority of which are false
     positives. On an allmodconfig kernel the number of false positive
     context tracking Sparse warnings grows to over 5,200... On the plus
     side of the balance actual locking bugs found by Sparse context
     analysis is also rather ... sparse: I found only 3 such commits in
     the last 3 years. So the rate of false positives and the
     maintenance overhead is rather high and there appears to be no
     active policy in place to achieve a zero-warnings baseline to move
     the annotations & fixers to developers who introduce new code.

     Clang context analysis is more complete and more aggressive in
     trying to find bugs, at least in principle. Plus it has a different
     model to enabling it: it's enabled subsystem by subsystem, which
     results in zero warnings on all relevant kernel builds (as far as
     our testing managed to cover it). Which allowed us to enable it by
     default, similar to other compiler warnings, with the expectation
     that there are no warnings going forward. This enforces a
     zero-warnings baseline on clang-22+ builds (Which are still limited
     in distribution, admittedly)

     Hopefully the Clang approach can lead to a more maintainable
     zero-warnings status quo and policy, with more and more subsystems
     and drivers enabling the feature. Context tracking can be enabled
     for all kernel code via WARN_CONTEXT_ANALYSIS_ALL=y (default
     disabled), but this will generate a lot of false positives.

     ( Having said that, Sparse support could still be added back,
       if anyone is interested - the removal patch is still
       relatively straightforward to revert at this stage. )

 "x86 PMU driver updates:

   - Add support for the core PMU for Intel Diamond Rapids (DMR) CPUs
     (Dapeng Mi)

     Compared to previous iterations of the Intel PMU code, there's been
     a lot of changes, which center around three main areas:

      - Introduce the OFF-MODULE RESPONSE (OMR) facility to replace the
        Off-Core Response (OCR) facility

      - New PEBS data source encoding layout

      - Support the new "RDPMC user disable" feature

   - Likewise, a large series adds uncore PMU support for Intel Diamond
     Rapids (DMR) CPUs (Zide Chen)

     This centers around these four main areas:

      - DMR may have two Integrated I/O and Memory Hub (IMH) dies,
        separate from the compute tile (CBB) dies. Each CBB and each IMH
        die has its own discovery domain.

      - Unlike prior CPUs that retrieve the global discovery table
        portal exclusively via PCI or MSR, DMR uses PCI for IMH PMON
        discovery and MSR for CBB PMON discovery.

      - DMR introduces several new PMON types: SCA, HAMVF, D2D_ULA, UBR,
        PCIE4, CRS, CPC, ITC, OTC, CMS, and PCIE6.

      - IIO free-running counters in DMR are MMIO-based, unlike SPR.

   - Also add support for Add missing PMON units for Intel Panther Lake,
     and support Nova Lake (NVL), which largely maps to Panther Lake.
     (Zide Chen)

   - KVM integration: Add support for mediated vPMUs (by Kan Liang and
     Sean Christopherson, with fixes and cleanups by Peter Zijlstra,
     Sandipan Das and Mingwei Zhang)

   - Add Intel cstate driver to support for Wildcat Lake (WCL) CPUs,
     which are a low-power variant of Panther Lake (Zide Chen)

   - Add core, cstate and MSR PMU support for the Airmont NP Intel CPU
     (aka MaxLinear Lightning Mountain), which maps to the existing
     Airmont code (Martin Schiller)

   - Speed up kexec shutdown by avoiding unnecessary cross CPU calls
     (Jan H. Schönherr)

Pull vfs error reporting updates from Christian Brauner:
 "This contains the changes to support generic I/O error reporting.

  Filesystems currently have no standard mechanism for reporting
  metadata corruption and file I/O errors to userspace via fsnotify.
  Each filesystem (xfs, ext4, erofs, f2fs, etc.) privately defines
  EFSCORRUPTED, and error reporting to fanotify is inconsistent or
  absent entirely.

  This introduces a generic fserror infrastructure built around struct
  super_block that gives filesystems a standard way to queue metadata
  and file I/O error reports for delivery to fsnotify.

  Errors are queued via mempools and queue_work to avoid holding
  filesystem locks in the notification path; unmount waits for pending
  events to drain. A new super_operations::report_error callback lets
  filesystem drivers respond to file I/O errors themselves (to be used
  by an upcoming XFS self-healing patchset).

  On the uapi side, EFSCORRUPTED and EUCLEAN are promoted from private
  per-filesystem definitions to canonical errno.h values across all
  architectures"
