      Pull coccinelle semantic patch updates from Julia Lawall:
      
       - Update the semantic patches in the kernel that contain a URL for
         Coccinelle with a URL that is currently valid (from myself).
      
       - Add a semantic patch checking for unnecessary NULL tests on dev_{put,
         hold} functions (from Ziyang Xuan, followed bt a modification from
         myself).
      
       - Drop a semantic patch that replaces 0/1 by booleans, as this change
         was considered to be not worthwhile by some maintainers (from Steve
         Rostedt).
      
       - Extend an existing semantic patch with more checks for useless tests
         on variables addresses (from Jérémy Lefaure).

         This includes a few prerequisite updates and fixes to the oldmem
         reading code.
      
       - Rework cpufeature implementation to allow for various CPU feature
         indications, which is not only limited to hardware capabilities, but
         also allows CPU facilities.

         facility 158 is available.
      
       - Add ELF note type for encrypted CPU state of a protected virtual CPU.
         The zgetdump tool from s390-tools package will decrypt the CPU state
         using a Customer Communication Key and overwrite respective notes to
         make the data accessible for crash and other debugging tools.
      
       - Use vzalloc() instead of vmalloc() + memset() in ChaCha20 crypto
         test.

         stacktrace.
      
       - Switch the NMI handler to use generic irqentry_nmi_enter() and
         irqentry_nmi_exit() helper functions.
      
       - Rework the cryptographic Adjunct Processors (AP) pass-through design
         to support dynamic changes to the AP matrix of a running guest as
         well as to implement more of the AP architecture.

      Linus Torvalds authored
      This reverts commit 4bf7fda4.
      
      It turns out that it was hopelessly naive to think that this would work,
      considering that we've always done this.  The first machine I actually
      tested this on broke at bootup, getting to
      
          Reached target cryptsetup.target - Local Encrypted Volumes.
      
      and then hanging.  It's unclear what actually fails, since there's a lot
      else going on around that time (eg amdgpu probing also happens around
      that same time, but it could be some other random init thing that didn't
      complete earlier and just caused the boot to hang at that point).
      
      The expectations that we should default to some unsafe and untested mode
      seems entirely unfounded, and the belief that this wouldn't affect
      modern systems is clearly entirely false.  The machine in question is
      about two years old, so it's not exactly shiny, but it's also not some
      dusty old museum piece PDP-11 in a closet.

      Pull more device mapper updates from Mike Snitzer:
      
       - Add flags argument to dm_bufio_client_create and introduce
         DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather
         than mutex for its locking.
      
       - Add optional "try_verify_in_tasklet" feature to DM verity target.
         This feature gives users the option to improve IO latency by using a
         tasklet to verify, using hashes in bufio's cache, rather than wait to
         schedule a work item via workqueue. But if there is a bufio cache
         miss, or an error, then the tasklet will fallback to using workqueue.
      
       - Incremental changes to both dm-bufio and the DM verity target to use
         jump_label to minimize cost of branching associated with the niche
         "try_verify_in_tasklet" feature. DM-bufio in particular is used by
         quite a few other DM targets so it doesn't make sense to incur
         additional bufio cost in those targets purely for the benefit of this
         niche verity feature if the feature isn't ever used.
      
       - Optimize verity_verify_io, which is used by both workqueue and
         tasklet based verification, if FEC is not configured or tasklet based
         verification isn't used.
      
       - Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE
         flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if
         "try_verify_in_tasklet" is specified.

      Pull iommu updates from Joerg Roedel:
      
       - The most intrusive patch is small and changes the default allocation
         policy for DMA addresses.
      
         Before the change the allocator tried its best to find an address in
         the first 4GB. But that lead to performance problems when that space
         gets exhaused, and since most devices are capable of 64-bit DMA these
         days, we changed it to search in the full DMA-mask range from the
         beginning.
      
         This change has the potential to uncover bugs elsewhere, in the
         kernel or the hardware. There is a Kconfig option and a command line
         option to restore the old behavior, but none of them is enabled by
         default.

      Pull sound updates from Takashi Iwai:
       "As the diffstat shows, we've had lots of developments in a wide range
        at this time; the majority of changes are about ASoC, including
        subsystem-wide cleanups, continued SOF / Intel updates and a bunch of
        new drivers (as usual), while there have been some significant (but
        almost invisible) improvements in ALSA core side, too.
      
        Below are some highlights:
      
        Core:
      
         - Faster lookups of control elements with Xarray; normal user won't
           notice, but on the devices with tons of control elements, it can be
           visibly faster
      
         - Support for input validation for controls; this will harden for
           badly written drivers in general with a slight overhead
      
         - Deferred async signal handling for working around the potential
           deadlocks
      
         - Cleanup / refactoring raw MIDI locking code
      
        ASoC:
      
         - Restructing of the set_fmt() callbacks for making things clearer in
           situations like CODEC to CODEC links
      
         - Clean up and modernizing the DAI naming scheme setups
      
         - Merge of more of the Intel AVS driver stack, including some board
           integrations
      
         - New version 4 mechanism for communication with SOF DSPs
      
         - Suppoort for dynamically selecting the PLL to use at runtime on
           i.MX platforms
      
         - Improvements for CODEC to CODEC support in the generic cards
      
         - Support for AMD Jadeite and various machines, AMD RPL, Intel
           MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
           MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
           WAS883x, and Texas Instruments TAS2780
      
        HD- and USB-audio:
      
         - Continued improvement for CS35L41 (sub)codec support
      
         - More quirks for various devices (HP, Lenovo, Dell, Clevo)"

      Pull perf tools updates from Arnaldo Carvalho de Melo:
      
       - Introduce 'perf lock contention' subtool, using new lock contention
         tracepoints and using BPF for in kernel aggregation and then
         userspace processing using the perf tooling infrastructure for
         resolving symbols, target specification, etc.
      
         Since the new lock contention tracepoints don't provide lock names,
         get up to 8 stack traces and display the first non-lock function
         symbol name as a caller:
      
          $ perf lock report -F acquired,contended,avg_wait,wait_total

         Supports the usual 'perf record' + 'perf report' workflow as well as
         a BCC/bpftrace like mode where you start the tool and then press
         control+C to get results:

       - Add new 'perf kwork' tool to trace time properties of kernel work
         (such as softirq, and workqueue), uses eBPF skeletons to collect info
         in kernel space, aggregating data that then gets processed by the
         userspace tool, e.g.:
      
          # perf kwork report
      
           Kwork Name      | Cpu | Total Runtime | Count | Max runtime | Max runtime start | Max runtime end |

         See commit log messages for more examples with extra options to limit
         the events time window, etc.
      
       - Add support for new AMD IBS (Instruction Based Sampling) features:
      
         With the DataSrc extensions, the source of data can be decoded among:
           - Local L3 or other L1/L2 in CCX.
           - A peer cache in a near CCX.
           - Data returned from DRAM.
           - A peer cache in a far CCX.
           - DRAM address map with "long latency" bit set.
           - Data returned from MMIO/Config/PCI/APIC.
           - Extension Memory (S-Link, GenZ, etc - identified by the CS target
             and/or address map at DF's choice).
           - Peer Agent Memory.
      
       - Support hardware tracing with Intel PT on guest machines, combining
         the traces with the ones in the host machine.
      
       - Add a "-m" option to 'perf buildid-list' to show kernel and modules
         build-ids, to display all of the information needed to do external
         symbolization of kernel stack traces, such as those collected by
         bpf_get_stackid().
      
       - Add arch TSC frequency information to perf.data file headers.
      
       - Handle changes in the binutils disassembler function signatures in
         perf, bpftool and bpf_jit_disasm (Acked by the bpftool maintainer).
      
       - Fix building the perf perl binding with the newest gcc in distros
         such as fedora rawhide, where some new warnings were breaking the
         build as perf uses -Werror.
      
       - Add 'perf test' entry for branch stack sampling.
      
       - Add ARM SPE system wide 'perf test' entry.
      
       - Add user space counter reading tests to 'perf test'.

       - Add vendor JSON File for Intel meteorlake.
      
       - Add Arm Cortex-A78C and X1C JSON vendor event files.
      
       - Add workaround to symbol address reading from ELF files without phdr,
         falling back to the previoous equation.
      
       - Convert legacy map definition to BTF-defined in the perf BPF script
         test.
      
       - Rework prologue generation code to stop using libbpf deprecated APIs.
      
       - Add default hybrid events for 'perf stat' on x86.
      
       - Add topdown metrics in the default 'perf stat' on the hybrid machines
         (big/little cores).
      
       - Prefer sampled CPU when exporting JSON in 'perf data convert'
      
       - Fix ('perf stat CSV output linter') and ("Check branch stack
         sampling") 'perf test' entries on s390.

      This reverts commit 7d06fed7.
      
      This introduced vmem_mutex locking from vmem_map_4k_page()
      function called from smp_reinit_ipl_cpu() with interrupts
      disabled. While it is a pre-SMP early initcall no other CPUs
      running in parallel nor other code taking vmem_mutex on this
      boot stage - it still needs to be fixed.

       "Most of the MM queue. A few things are still pending.
      
        Liam's maple tree rework didn't make it. This has resulted in a few
        other minor patch series being held over for next time.
      
        Multi-gen LRU still isn't merged as we were waiting for mapletree to
        stabilize. The current plan is to merge MGLRU into -mm soon and to
        later reintroduce mapletree, with a view to hopefully getting both
        into 6.1-rc1.
      
        Summary:
      
         - The usual batches of cleanups from Baoquan He, Muchun Song, Miaohe
           Lin, Yang Shi, Anshuman Khandual and Mike Rapoport

         - do not change nor->addr_nbytes at SFDP parsing time. At the SFDP
           parsing time we should not change members of struct spi_nor, but
           instead fill members of struct spi_nor_flash_parameters which could
           later on be used by the callers.
