      Pull perf events updates from Ingo Molnar:
       "Platform PMU changes:
      
         - x86/intel:
            - Add new Intel Alder Lake and Raptor Lake support
      
         - x86/amd:
            - AMD Zen4 IBS extensions support
            - Add AMD PerfMonV2 support
            - Add AMD Fam19h Branch Sampling support
      
        Generic changes:
      
         - signal: Deliver SIGTRAP on perf event asynchronously if blocked
      
           Perf instrumentation can be driven via SIGTRAP, but this causes a
           problem when SIGTRAP is blocked by a task & terminate the task.
      
           Allow user-space to request these signals asynchronously (after
           they get unblocked) & also give the information to the signal
           handler when this happens:
      
             "To give user space the ability to clearly distinguish
              synchronous from asynchronous signals, introduce
              siginfo_t::si_perf_flags and TRAP_PERF_FLAG_ASYNC (opted for
              flags in case more binary information is required in future).
      
              The resolution to the problem is then to (a) no longer force the
              signal (avoiding the terminations), but (b) tell user space via
              si_perf_flags if the signal was synchronous or not, so that such
              signals can be handled differently (e.g. let user space decide
              to ignore or consider the data imprecise). "
      
         - Unify/standardize the /sys/devices/cpu/events/* output format.

      Pull objtool updates from Ingo Molnar:
      
       - Comprehensive interface overhaul:
         =================================
      
         Objtool's interface has some issues:
      
           - Several features are done unconditionally, without any way to
             turn them off. Some of them might be surprising. This makes
             objtool tricky to use, and prevents porting individual features
             to other arches.
      
           - The config dependencies are too coarse-grained. Objtool
             enablement is tied to CONFIG_STACK_VALIDATION, but it has several
             other features independent of that.
      
           - The objtool subcmds ("check" and "orc") are clumsy: "check" is
             really a subset of "orc", so it has all the same options.
      
             The subcmd model has never really worked for objtool, as it only
             has a single purpose: "do some combination of things on an object
             file".
      
           - The '--lto' and '--vmlinux' options are nonsensical and have
             surprising behavior.
      
         Overhaul the interface:
      
            - get rid of subcmds
      
            - make all features individually selectable
      
            - remove and/or clarify confusing/obsolete options
      
            - update the documentation
      
            - fix some bugs found along the way
      
       - Fix x32 regression
      
       - Fix Kbuild cleanup bugs
      
       - Add scripts/objdump-func helper script to disassemble a single
         function from an object file.
      
       - Rewrite scripts/faddr2line to be section-aware, by basing it on
         'readelf', moving it away from 'nm', which doesn't handle multiple
         sections well, which can result in decoding failure.
      
       - Rewrite & fix symbol handling - which had a number of bugs wrt.
         object files that don't have global symbols - which is rare but
         possible. Also fix a bunch of symbol handling bugs found along the
         way.

      Pull arm64 updates from Catalin Marinas:
      
       - Initial support for the ARMv9 Scalable Matrix Extension (SME).
      
         SME takes the approach used for vectors in SVE and extends this to
         provide architectural support for matrix operations. No KVM support
         yet, SME is disabled in guests.
      
       - Support for crashkernel reservations above ZONE_DMA via the
         'crashkernel=X,high' command line option.
      
       - btrfs search_ioctl() fix for live-lock with sub-page faults.

         monitoring coherent I/O traffic, support for Arm's CMN-650 and
         CMN-700 interconnect PMUs, minor driver fixes, kerneldoc cleanup.
      
       - Kselftest updates for SME, BTI, MTE.
      
       - Automatic generation of the system register macros from a 'sysreg'
         file describing the register bitfields.
      
       - Update the type of the function argument holding the ESR_ELx register
         value to unsigned long to match the architecture register size
         (originally 32-bit but extended since ARMv8.0).
      
       - stacktrace cleanups.
      
       - ftrace cleanups.
      
       - Miscellaneous updates, most notably: arm64-specific huge_ptep_get(),
         avoid executable mappings in kexec/hibernate code, drop TLB flushing
         from get_clear_flush() (and rename it to get_clear_contig()),
         ARCH_NR_GPIO bumped to 2048 for ARCH_APPLE.

        pressure:
      
        SGX uses normal RAM allocated from special shmem files as backing
        storage when it runs out of SGX memory (EPC). The code was overly
        aggressive when freeing shmem pages and was inadvertently freeing
        perfectly good data. This resulted in failures in the SGX instructions
        used to swap data back into SGX memory.
      
        This turned out to be really hard to trigger in mainline. It was
        originally encountered testing the out-of-tree "SGX2" patches, but
        later reproduced on mainline.

        the backing storage and more judiciously setting pages dirty"

      Pull Intel TDX support from Borislav Petkov:
       "Intel Trust Domain Extensions (TDX) support.
      
        This is the Intel version of a confidential computing solution called
        Trust Domain Extensions (TDX). This series adds support to run the
        kernel as part of a TDX guest. It provides similar guest protections
        to AMD's SEV-SNP like guest memory and register state encryption,
        memory integrity protection and a lot more.
      
        Design-wise, it differs from AMD's solution considerably: it uses a
        software module which runs in a special CPU mode called (Secure
        Arbitration Mode) SEAM. As the name suggests, this module serves as
        sort of an arbiter which the confidential guest calls for services it
        needs during its lifetime.
      
        Just like AMD's SNP set, this series reworks and streamlines certain
        parts of x86 arch code so that this feature can be properly
        accomodated"

       "The third AMD confidential computing feature called Secure Nested
        Paging.
      
        Add to confidential guests the necessary memory integrity protection
        against malicious hypervisor-based attacks like data replay, memory
        remapping and others, thus achieving a stronger isolation from the
        hypervisor.
      
        At the core of the functionality is a new structure called a reverse
        map table (RMP) with which the guest has a say in which pages get
        assigned to it and gets notified when a page which it owns, gets
        accessed/modified under the covers so that the guest can take an
        appropriate action.
      
        In addition, add support for the whole machinery needed to launch a
        SNP guest, details of which is properly explained in each patch.
