Pull drm ci scripts from Dave Airlie:
 "This is a bunch of ci integration for the freedesktop gitlab instance
  where we currently do upstream userspace testing on diverse sets of
  GPU hardware. From my perspective I think it's an experiment worth
  going with and seeing how the benefits/noise playout keeping these
  files useful.

  Ideally I'd like to get this so we can do pre-merge testing on PRs
  eventually.

  Below is some info from danvet on why we've ended up making the
  decision and how we can roll it back if we decide it was a bad plan.

  Why in upstream?

   - like documentation, testcases, tools CI integration is one of these
     things where you can waste endless amounts of time if you
     accidentally have a version that doesn't match your source code

   - but also like the above, there's a balance, this is the initial cut
     of what we think makes sense to keep in sync vs out-of-tree,
     probably needs adjustment

   - gitlab supports out-of-repo gitlab integration and that's what's
     been used for the kernel in drm, but it results in per-driver
     fragmentation and lots of duplicated effort. the simple act of
     smashing an arbitrary winner into a topic branch already started
     surfacing patches on dri-devel and sparking good cross driver team
     discussions

  Why gitlab?

   - it's not any more shit than any of the other CI

   - drm userspace uses it extensively for everything in userspace, we
     have a lot of people and experience with this, including
     integration of hw testing labs

   - media userspace like gstreamer is also on gitlab.fd.o, and there's
     discussion to extend this to the media subsystem in some fashion

  Can this be shared?

   - there's definitely a pile of code that could move to scripts/ if
     other subsystem adopt ci integration in upstream kernel git. other
     bits are more drm/gpu specific like the igt-gpu-tests/tools
     integration

   - docker images can be run locally or in other CI runners

  Will we regret this?

   - it's all in one directory, intentionally, for easy deletion

   - probably 1-2 years in upstream to see whether this is worth it or a
     Big Mistake. that's roughly what it took to _really_ roll out solid
     CI in the bigger userspace projects we have on gitlab.fd.o like
     mesa3d"

535a265d7f perf tools changes for v6.6: 
perf tools maintainership:
 
 - Add git information for perf-tools and perf-tools-next trees/branches to the
   MAINTAINERS file. That is where development now takes place and myself and
   Namhyung Kim have write access, more people to come as we emulate other
   maintainer groups.
 
 perf record:
 
 - Record kernel data maps when 'perf record --data' is used, so that global variables can
   be resolved and used in tools that do data profiling.
 
 perf trace:
 
 - Remove the old, experimental support for BPF events in which a .c file was passed as
   an event: "perf trace -e hello.c" to then get compiled and loaded.
 
   The only known usage for that, that shipped with the kernel as an example for such events,
   augmented the raw_syscalls tracepoints and was converted to a libbpf skeleton, reusing all
   the user space components and the BPF code connected to the syscalls.
 
   In the end just the way to glue the BPF part and the user space type beautifiers changed,
   now being performed by libbpf skeletons.
 
   The next step is to use BTF to do pretty printing of all syscall types, as discussed with
   Alan Maguire and others.
 
   Now, on a perf built with BUILD_BPF_SKEL=1 we get most if not all path/filenames/strings,
   some of the networking data structures, perf_event_attr, etc, i.e. systemwide tracing of
   nanosleep calls and perf_event_open syscalls while 'perf stat' runs 'sleep' for 5 seconds:

 perf annotate:
 
 - Building with binutils' libopcode now is opt-in (BUILD_NONDISTRO=1) for
   licensing reasons, and we missed a build test on tools/perf/tests makefile.
 
   Since we now default to NDEBUG=1, we ended up segfaulting when building with
   BUILD_NONDISTRO=1 because a needed initialization routine was being "error
   checked" via an assert.
 
   Fix it by explicitly checking the result and aborting instead if it fails.
 
   We better back propagate the error, but at least 'perf annotate' on samples
   collected for a BPF program is back working when perf is built with
   BUILD_NONDISTRO=1.
 
 perf report/top:
 
 - Add back TUI hierarchy mode header, that is seen when using 'perf report/top --hierarchy'.
 
 - Fix the number of entries for 'e' key in the TUI that was preventing navigation of
   lines when expanding an entry.
 
 perf report/script:
 
 - Support cross platform register handling, allowing a perf.data file collected
   on one architecture to have registers sampled correctly displayed when
   analysis tools such as 'perf report' and 'perf script' are used on a different
   architecture.
 
 - Fix handling of event attributes in pipe mode, i.e. when one uses:
 
 	perf record -o - | perf report -i -
 
   When no perf.data files are used.
 
 - Handle files generated via pipe mode with a version of perf and then read
   also via pipe mode with a different version of perf, where the event attr
   record may have changed, use the record size field to properly support this
   version mismatch.
 
 perf probe:
 
 - Accessing global variables from uprobes isn't supported, make the error
   message state that instead of stating that some minimal kernel version is
   needed to have that feature. This seems just a tool limitation, the kernel
   probably has all that is needed.
 
 perf tests:
 
 - Fix a reference count related leak in the dlfilter v0 API where the result
   of a thread__find_symbol_fb() is not matched with an addr_location__exit()
   to drop the reference counts of the resolved components (machine, thread, map,
   symbol, etc). Add a dlfilter test to make sure that doesn't regresses.
 
 - Lots of fixes for the 'perf test' written in shell script related to problems
   found with the shellcheck utility.
 
 - Fixes for 'perf test' shell scripts testing features enabled when perf is
   built with BUILD_BPF_SKEL=1, such as 'perf stat' bpf counters.
 
 - Add perf record sample filtering test, things like the following example, that gets
   implemented as a BPF filter attached to the event:
 
    # perf record -e task-clock -c 10000 --filter 'ip < 0xffffffff00000000'
 
 - Improve the way the task_analyzer test checks if libtraceevent is linked,
   using 'perf version --build-options' instead of the more expensinve
   'perf record -e "sched:sched_switch"'.
 
 - Add support for riscv in the mmap-basic test. (This went as well via the RiscV tree, same contents).
 
 libperf:
 
 - Implement riscv mmap support (This went as well via the RiscV tree, same contents).
 
 perf script:
 
 - New tool that converts perf.data files to the firefox profiler format so that one can use
   the visualizer at https://profiler.firefox.com/. Done by Anup Sharma as part of this year's
   Google Summer of Code.
 
   One can generate the output and upload it to the web interface but Anup also automated
   everything:
 
      perf script gecko -F 99 -a sleep 60
 
 - Support syscall name parsing on arm64.
 
 - Print "cgroup" field on the same line as "comm".
 
 perf bench:
 
 - Add new 'uprobe' benchmark to measure the overhead of uprobes with/without
   BPF programs attached to it.
 
 - breakpoints are not available on power9, skip that test.
 
 perf stat:
 
 - Add #num_cpus_online literal to be used in 'perf stat' metrics, and add this extra
   'perf test' check that exemplifies its purpose:
 
 	TEST_ASSERT_VAL("#num_cpus_online",
                        expr__parse(&num_cpus_online, ctx, "#num_cpus_online") == 0);
 	TEST_ASSERT_VAL("#num_cpus", expr__parse(&num_cpus, ctx, "#num_cpus") == 0);
 	TEST_ASSERT_VAL("#num_cpus >= #num_cpus_online", num_cpus >= num_cpus_online);
 
 Miscellaneous:
 
 - Improve tool startup time by lazily reading PMU, JSON, sysfs data.
 
 - Improve error reporting in the parsing of events, passing YYLTYPE to error routines,
   so that the output can show were the parsing error was found.
 
 - Add 'perf test' entries to check the parsing of events improvements.
 
 - Fix various leak for things detected by -fsanitize=address, mostly things that would
   be freed at tool exit, including:
 
   - Free evsel->filter on the destructor.
 
   - Allow tools to register a thread->priv destructor and use it in 'perf trace'.
 
   - Free evsel->priv in 'perf trace'.
 
   - Free string returned by synthesize_perf_probe_point() when the caller fails
     to do all it needs.
 
 - Adjust various compiler options to not consider errors some warnings when
   building with broken headers found in things like python, flex, bison, as we
   otherwise build with -Werror. Some for gcc, some for clang, some for some
   specific version of those, some for some specific version of flex or bison, or
   some specific combination of these components, bah.
 
 - Allow customization of clang options for BPF target, this helps building on
   gentoo where there are other oddities where BPF targets gets passed some compiler
   options intended for the native build, so building with WERROR=0 helps while
   these oddities are fixed.
 
 - Dont pass ERR_PTR() values to perf_session__delete() in 'perf top' and 'perf lock',
   fixing some segfaults when handling some odd failures.
 
 - Add LTO build option.
 
 - Fix format of unordered lists in the perf docs (tools/perf/Documentation).
 
 - Overhaul the bison files, using constructs such as YYNOMEM.
 
 - Remove unused tokens from the bison .y files.
 
 - Add more comments to various structs.
 
 - A few LoongArch enablement patches.
 
 Vendor events (JSON):
 
 - Add JSON metrics for Yitian 710 DDR (aarch64). Things like:
 
 	EventName, BriefDescription
 	visible_window_limit_reached_rd, "At least one entry in read queue reaches the visible window limit.",
 	visible_window_limit_reached_wr, "At least one entry in write queue reaches the visible window limit.",
 	op_is_dqsosc_mpc	       , "A DQS Oscillator MPC command to DRAM.",
 	op_is_dqsosc_mrr	       , "A DQS Oscillator MRR command to DRAM.",
 	op_is_tcr_mrr		       , "A Temperature Compensated Refresh(TCR) MRR command to DRAM.",
 
 - Add AmpereOne metrics (aarch64).
 
 - Update N2 and V2 metrics (aarch64) and events using Arm telemetry repo.
 
 - Update scale units and descriptions of common topdown metrics on aarch64. Things like:
 
   - "MetricExpr": "stall_slot_frontend / (#slots * cpu_cycles)",
   - "BriefDescription": "Frontend bound L1 topdown metric",
   + "MetricExpr": "100 * (stall_slot_frontend / (#slots * cpu_cycles))",
   + "BriefDescription": "This metric is the percentage of total slots that were stalled due to resource constraints in the frontend of the processor.",
 
 - Update events for intel: meteorlake to 1.04, sapphirerapids to 1.15, Icelake+ metric constraints.
 
 - Update files for the power10 platform.

  perf annotate:

   - Building with binutils' libopcode now is opt-in (BUILD_NONDISTRO=1)
     for licensing reasons, and we missed a build test on
     tools/perf/tests makefile.

     Since we now default to NDEBUG=1, we ended up segfaulting when
     building with BUILD_NONDISTRO=1 because a needed initialization
     routine was being "error checked" via an assert.

     Fix it by explicitly checking the result and aborting instead if it
     fails.

     We better back propagate the error, but at least 'perf annotate' on
     samples collected for a BPF program is back working when perf is
     built with BUILD_NONDISTRO=1.

  perf report/top:

   - Add back TUI hierarchy mode header, that is seen when using 'perf
     report/top --hierarchy'.

   - Fix the number of entries for 'e' key in the TUI that was
     preventing navigation of lines when expanding an entry.

  perf report/script:

   - Support cross platform register handling, allowing a perf.data file
     collected on one architecture to have registers sampled correctly
     displayed when analysis tools such as 'perf report' and 'perf
     script' are used on a different architecture.

   - Fix handling of event attributes in pipe mode, i.e. when one uses:

  	perf record -o - | perf report -i -

     When no perf.data files are used.

   - Handle files generated via pipe mode with a version of perf and
     then read also via pipe mode with a different version of perf,
     where the event attr record may have changed, use the record size
     field to properly support this version mismatch.

  perf probe:

   - Accessing global variables from uprobes isn't supported, make the
     error message state that instead of stating that some minimal
     kernel version is needed to have that feature. This seems just a
     tool limitation, the kernel probably has all that is needed.

  perf tests:

   - Fix a reference count related leak in the dlfilter v0 API where the
     result of a thread__find_symbol_fb() is not matched with an
     addr_location__exit() to drop the reference counts of the resolved
     components (machine, thread, map, symbol, etc). Add a dlfilter test
     to make sure that doesn't regresses.

   - Lots of fixes for the 'perf test' written in shell script related
     to problems found with the shellcheck utility.

   - Fixes for 'perf test' shell scripts testing features enabled when
     perf is built with BUILD_BPF_SKEL=1, such as 'perf stat' bpf
     counters.

   - Add perf record sample filtering test, things like the following
     example, that gets implemented as a BPF filter attached to the
     event:

       # perf record -e task-clock -c 10000 --filter 'ip < 0xffffffff00000000'

   - Improve the way the task_analyzer test checks if libtraceevent is
     linked, using 'perf version --build-options' instead of the more
     expensinve 'perf record -e "sched:sched_switch"'.

   - Add support for riscv in the mmap-basic test. (This went as well
     via the RiscV tree, same contents).

  libperf:

   - Implement riscv mmap support (This went as well via the RiscV tree,
     same contents).

  perf script:

   - New tool that converts perf.data files to the firefox profiler
     format so that one can use the visualizer at
     https://profiler.firefox.com/. Done by Anup Sharma as part of this
     year's Google Summer of Code.

     One can generate the output and upload it to the web interface but
     Anup also automated everything:

       perf script gecko -F 99 -a sleep 60

   - Support syscall name parsing on arm64.

   - Print "cgroup" field on the same line as "comm".

  perf bench:

   - Add new 'uprobe' benchmark to measure the overhead of uprobes
     with/without BPF programs attached to it.

   - breakpoints are not available on power9, skip that test.

  perf stat:

   - Add #num_cpus_online literal to be used in 'perf stat' metrics, and
     add this extra 'perf test' check that exemplifies its purpose:

  	TEST_ASSERT_VAL("#num_cpus_online",
                         expr__parse(&num_cpus_online, ctx, "#num_cpus_online") == 0);
  	TEST_ASSERT_VAL("#num_cpus", expr__parse(&num_cpus, ctx, "#num_cpus") == 0);
  	TEST_ASSERT_VAL("#num_cpus >= #num_cpus_online", num_cpus >= num_cpus_online);

  Miscellaneous:

   - Improve tool startup time by lazily reading PMU, JSON, sysfs data.

   - Improve error reporting in the parsing of events, passing YYLTYPE
     to error routines, so that the output can show were the parsing
     error was found.

   - Add 'perf test' entries to check the parsing of events
     improvements.

   - Fix various leak for things detected by -fsanitize=address, mostly
     things that would be freed at tool exit, including:

       - Free evsel->filter on the destructor.

       - Allow tools to register a thread->priv destructor and use it in
         'perf trace'.

       - Free evsel->priv in 'perf trace'.

       - Free string returned by synthesize_perf_probe_point() when the
         caller fails to do all it needs.

   - Adjust various compiler options to not consider errors some
     warnings when building with broken headers found in things like
     python, flex, bison, as we otherwise build with -Werror. Some for
     gcc, some for clang, some for some specific version of those, some
     for some specific version of flex or bison, or some specific
     combination of these components, bah.

   - Allow customization of clang options for BPF target, this helps
     building on gentoo where there are other oddities where BPF targets
     gets passed some compiler options intended for the native build, so
     building with WERROR=0 helps while these oddities are fixed.

   - Dont pass ERR_PTR() values to perf_session__delete() in 'perf top'
     and 'perf lock', fixing some segfaults when handling some odd
     failures.

   - Add LTO build option.

   - Fix format of unordered lists in the perf docs
     (tools/perf/Documentation)

   - Overhaul the bison files, using constructs such as YYNOMEM.

   - Remove unused tokens from the bison .y files.

   - Add more comments to various structs.

   - A few LoongArch enablement patches.

  Vendor events (JSON):

   - Add JSON metrics for Yitian 710 DDR (aarch64). Things like:

  	EventName, BriefDescription
  	visible_window_limit_reached_rd, "At least one entry in read queue reaches the visible window limit.",
  	visible_window_limit_reached_wr, "At least one entry in write queue reaches the visible window limit.",
  	op_is_dqsosc_mpc	       , "A DQS Oscillator MPC command to DRAM.",
  	op_is_dqsosc_mrr	       , "A DQS Oscillator MRR command to DRAM.",
  	op_is_tcr_mrr		       , "A Temperature Compensated Refresh(TCR) MRR command to DRAM.",

   - Add AmpereOne metrics (aarch64).

   - Update N2 and V2 metrics (aarch64) and events using Arm telemetry
     repo.

   - Update scale units and descriptions of common topdown metrics on
     aarch64. Things like:
       - "MetricExpr": "stall_slot_frontend / (#slots * cpu_cycles)",
       - "BriefDescription": "Frontend bound L1 topdown metric",
       + "MetricExpr": "100 * (stall_slot_frontend / (#slots * cpu_cycles))",
       + "BriefDescription": "This metric is the percentage of total slots that were stalled due to resource constraints in the frontend of the processor.",

   - Update events for intel: meteorlake to 1.04, sapphirerapids to
     1.15, Icelake+ metric constraints.

   - Update files for the power10 platform"

Merge patch series "Add non-coherent DMA support for AX45MP" 
Prabhakar <prabhakar.csengg@gmail.com> says:

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

non-coherent DMA support for AX45MP
====================================

On the Andes AX45MP core, cache coherency is a specification option so it
may not be supported. In this case DMA will fail. To get around with this
issue this patch series does the below:

1] Andes alternative ports is implemented as errata which checks if the
IOCP is missing and only then applies to CMO errata. One vendor specific
SBI EXT (ANDES_SBI_EXT_IOCP_SW_WORKAROUND) is implemented as part of
errata.

Below are the configs which Andes port provides (and are selected by
RZ/Five):
      - ERRATA_ANDES
      - ERRATA_ANDES_CMO

OpenSBI patch supporting ANDES_SBI_EXT_IOCP_SW_WORKAROUND SBI is now
part v1.3 release.

2] Andes AX45MP core has a Programmable Physical Memory Attributes (PMA)
block that allows dynamic adjustment of memory attributes in the runtime.
It contains a configurable amount of PMA entries implemented as CSR
registers to control the attributes of memory locations in interest.
OpenSBI configures the PMA regions as required and creates a reserve memory
node and propagates it to the higher boot stack.

Currently OpenSBI (upstream) configures the required PMA region and passes
this a shared DMA pool to Linux.

    reserved-memory {
        #address-cells = <2>;
        #size-cells = <2>;
        ranges;

        pma_resv0@58000000 {
            compatible = "shared-dma-pool";
            reg = <0x0 0x58000000 0x0 0x08000000>;
            no-map;
            linux,dma-default;
        };
    };

The above shared DMA pool gets appended to Linux DTB so the DMA memory
requests go through this region.

3] We provide callbacks to synchronize specific content between memory and
cache.

4] RZ/Five SoC selects the below configs
        - AX45MP_L2_CACHE
        - DMA_GLOBAL_POOL
        - ERRATA_ANDES
        - ERRATA_ANDES_CMO

* Clean up vCPU targets, always returning generic v8 as the preferred target
 
 * Trap forwarding infrastructure for nested virtualization (used for traps
   that are taken from an L2 guest and are needed by the L1 hypervisor)
 
 * FEAT_TLBIRANGE support to only invalidate specific ranges of addresses
   when collapsing a table PTE to a block PTE.  This avoids that the guest
   refills the TLBs again for addresses that aren't covered by the table PTE.
 
 * Fix vPMU issues related to handling of PMUver.
 
 * Don't unnecessary align non-stack allocations in the EL2 VA space
 
 * Drop HCR_VIRT_EXCP_MASK, which was never used...
 
 * Don't use smp_processor_id() in kvm_arch_vcpu_load(),
   but the cpu parameter instead
 
 * Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()
 
 * Remove prototypes without implementations
 
 RISC-V:
 
 * Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest
 
 * Added ONE_REG interface for SATP mode
 
 * Added ONE_REG interface to enable/disable multiple ISA extensions
 
 * Improved error codes returned by ONE_REG interfaces
 
 * Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V
 
 * Added get-reg-list selftest for KVM RISC-V
 
 s390:
 
 * PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
   Allows a PV guest to use crypto cards. Card access is governed by
   the firmware and once a crypto queue is "bound" to a PV VM every
   other entity (PV or not) looses access until it is not bound
   anymore. Enablement is done via flags when creating the PV VM.
 
 * Guest debug fixes (Ilya)
 
 x86:
 
 * Clean up KVM's handling of Intel architectural events
 
 * Intel bugfixes
 
 * Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use debug
   registers and generate/handle #DBs
 
 * Clean up LBR virtualization code
 
 * Fix a bug where KVM fails to set the target pCPU during an IRTE update
 
 * Fix fatal bugs in SEV-ES intrahost migration
 
 * Fix a bug where the recent (architecturally correct) change to reinject
   #BP and skip INT3 broke SEV guests (can't decode INT3 to skip it)
 
 * Retry APIC map recalculation if a vCPU is added/enabled
 
 * Overhaul emergency reboot code to bring SVM up to par with VMX, tie the
   "emergency disabling" behavior to KVM actually being loaded, and move all of
   the logic within KVM
 
 * Fix user triggerable WARNs in SVM where KVM incorrectly assumes the TSC
   ratio MSR cannot diverge from the default when TSC scaling is disabled
   up related code
 
 * Add a framework to allow "caching" feature flags so that KVM can check if
   the guest can use a feature without needing to search guest CPUID
 
 * Rip out the ancient MMU_DEBUG crud and replace the useful bits with
   CONFIG_KVM_PROVE_MMU
 
 * Fix KVM's handling of !visible guest roots to avoid premature triple fault
   injection
 
 * Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the API surface
   that is needed by external users (currently only KVMGT), and fix a variety
   of issues in the process
 
 This last item had a silly one-character bug in the topic branch that
 was sent to me.  Because it caused pretty bad selftest failures in
 some configurations, I decided to squash in the fix.  So, while the
 exact commit ids haven't been in linux-next, the code has (from the
 kvm-x86 tree).
 
 Generic:
 
 * Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier events to pass
   action specific data without needing to constantly update the main handlers.
 
 * Drop unused function declarations
 
 Selftests:
 
 * Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs
 
 * Add support for printf() in guest code and covert all guest asserts to use
   printf-based reporting
 
 * Clean up the PMU event filter test and add new testcases
 
 * Include x86 selftests in the KVM x86 MAINTAINERS entry

65d6e954e3 gfs2 fixes 
- Fix a glock state (non-)transition bug when a dlm request times out
   and is canceled, and we have locking requests that can now be granted
   immediately.
 
 - Various fixes and cleanups in how the logd and quotad daemons are
   woken up and terminated.
 
 - Fix several bugs in the quota data reference counting and shrinking.
   Free quota data objects synchronously in put_super() instead of
   letting call_rcu() run wild.
 
 - Make sure not to deallocate quota data during a withdraw; rather, defer
   quota data deallocation to put_super().  Withdraws can happen in
   contexts in which callers on the stack are holding quota data references.
 
 - Many minor quota fixes and cleanups by Bob.
 
 - Update the the mailing list address for gfs2 and dlm.  (It's the same
   list for both and we are moving it to gfs2@lists.linux.dev.)

     .set_trips callback (Mikko Perttunen).
 
   - Add new Loongson-2 thermal sensor along with the DT bindings (Yinbo
     Zhu).
 
   - Use IS_ERR_OR_NULL() helper to replace a double test on the TI
     bandgap sensor (Li Zetao).
 
   - Remove redundant platform_set_drvdata() calls, as there are no
     corresponding calls to platform_get_drvdata(), from a bunch of
     drivers (Andrei Coardos).
 
   - Switch the Mediatek LVTS mode to filtered in order to enable
     interrupts (Nícolas F. R. A. Prado).
 
   - Fix Wvoid-pointer-to-enum-cast warning on the Exynos TMU (Krzysztof
     Kozlowski).
 
   - Remove redundant dev_err_probe(), because the underlying function
     already called it, from the Mediatek sensor (Chen Jiahao).
 
    - Free calibration nvmem after reading it on sun8i (Mark Brown).
 
    - Remove useless comment from the sun8i driver (Yangtao Li).
 
    - Make tsens_xxxx_nvmem static to fix a sparse warning on QCom
      tsens (Min-Hua Chen).
 
    - Remove error message at probe deferral on imx8mm (Ahmad Fatoum).
 
    - Fix parameter check in lvts_debugfs_init() with IS_ERR() on
      Mediatek LVTS (Minjie Du).
 
    - Fix interrupt routine and configuratoin for Mediatek LVTS (Nícolas
      F. R. A. Prado).
 
    - Drop unused .get_trip_type(), .get_trip_temp() and .get_trip_hyst()
      thermal zone callbacks from the core and rework the .get_trend()
      one to take a trip point pointer as an argument (Rafael Wysocki).

Merge tag 'thermal-6.6-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more thermal control updates from Rafael Wysocki:
 "These are mostly updates of thermal control drivers for ARM platforms,
  new thermal control support for Loongson-2 and a couple of core
  cleanups made possible by recent changes merged previously.

  Specifics:

   - Check if the Tegra BPMP supports the trip points in order to set
     the .set_trips callback (Mikko Perttunen)

   - Add new Loongson-2 thermal sensor along with the DT bindings (Yinbo
     Zhu)

   - Use IS_ERR_OR_NULL() helper to replace a double test on the TI
     bandgap sensor (Li Zetao)

   - Remove redundant platform_set_drvdata() calls, as there are no
     corresponding calls to platform_get_drvdata(), from a bunch of
     drivers (Andrei Coardos)

   - Switch the Mediatek LVTS mode to filtered in order to enable
     interrupts (Nícolas F. R. A. Prado)

   - Fix Wvoid-pointer-to-enum-cast warning on the Exynos TMU (Krzysztof
     Kozlowski)

   - Remove redundant dev_err_probe(), because the underlying function
     already called it, from the Mediatek sensor (Chen Jiahao)

   - Free calibration nvmem after reading it on sun8i (Mark Brown)

   - Remove useless comment from the sun8i driver (Yangtao Li)

   - Make tsens_xxxx_nvmem static to fix a sparse warning on QCom tsens
     (Min-Hua Chen)

   - Remove error message at probe deferral on imx8mm (Ahmad Fatoum)

   - Fix parameter check in lvts_debugfs_init() with IS_ERR() on
     Mediatek LVTS (Minjie Du)

   - Fix interrupt routine and configuratoin for Mediatek LVTS (Nícolas
     F. R. A. Prado)

   - Drop unused .get_trip_type(), .get_trip_temp() and .get_trip_hyst()
     thermal zone callbacks from the core and rework the .get_trend()
     one to take a trip point pointer as an argument (Rafael Wysocki)"

7716f383a5 cgroup: Changes for v6.6 
* Per-cpu cpu usage stats are now tracked. This currently isn't printed out
   in the cgroupfs interface and can only be accessed through e.g. BPF.
   Should decide on a not-too-ugly way to show per-cpu stats in cgroupfs.
 
 * cpuset received some cleanups and prepatory patches for the pending
   cpus.exclusive patchset which will allow cpuset partitions to be created
   below non-partition parents, which should ease the management of partition
   cpusets.
 
 * A lot of code and documentation cleanup patches.
 
 * tools/testing/selftests/cgroup/test_cpuset.c is added. This causes trivial
   conflicts in .gitignore and Makefile under the directory against
   fe3b1bf19b ("selftests: cgroup: add test_zswap program"). They can be
   resolved by keeping lines from both branches.

Merge tag 'cgroup-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup

Pull cgroup updates from Tejun Heo:

 - Per-cpu cpu usage stats are now tracked

   This currently isn't printed out in the cgroupfs interface and can
   only be accessed through e.g. BPF. Should decide on a not-too-ugly
   way to show per-cpu stats in cgroupfs

 - cpuset received some cleanups and prepatory patches for the pending
   cpus.exclusive patchset which will allow cpuset partitions to be
   created below non-partition parents, which should ease the management
   of partition cpusets

 - A lot of code and documentation cleanup patches

 - tools/testing/selftests/cgroup/test_cpuset.c added

d34599bcd2
cache: Add L2 cache management for Andes AX45MP RISC-V core 
I/O Coherence Port (IOCP) provides an AXI interface for connecting
external non-caching masters, such as DMA controllers. The accesses
from IOCP are coherent with D-Caches and L2 Cache.

IOCP is a specification option and is disabled on the Renesas RZ/Five
SoC due to this reason IP blocks using DMA will fail.

The Andes AX45MP core has a Programmable Physical Memory Attributes (PMA)
block that allows dynamic adjustment of memory attributes in the runtime.
It contains a configurable amount of PMA entries implemented as CSR
registers to control the attributes of memory locations in interest.
Below are the memory attributes supported:
* Device, Non-bufferable
* Device, bufferable
* Memory, Non-cacheable, Non-bufferable
* Memory, Non-cacheable, Bufferable
* Memory, Write-back, No-allocate
* Memory, Write-back, Read-allocate
* Memory, Write-back, Write-allocate
* Memory, Write-back, Read and Write-allocate

More info about PMA (section 10.3):
Link: http://www.andestech.com/wp-content/uploads/AX45MP-1C-Rev.-5.0.0-Datasheet.pdf

As a workaround for SoCs with IOCP disabled CMO needs to be handled by
software. Firstly OpenSBI configures the memory region as
"Memory, Non-cacheable, Bufferable" and passes this region as a global
shared dma pool as a DT node. With DMA_GLOBAL_POOL enabled all DMA
allocations happen from this region and synchronization callbacks are
implemented to synchronize when doing DMA transactions.

Example PMA region passes as a DT node from OpenSBI:
    reserved-memory {
        #address-cells = <2>;
        #size-cells = <2>;
        ranges;

        pma_resv0@58000000 {
            compatible = "shared-dma-pool";
            reg = <0x0 0x58000000 0x0 0x08000000>;
            no-map;
            linux,dma-default;
        };
    };

    the vfio device fd from the container and group model, and is intended
    to be the native uAPI for use with IOMMUFD. (Yi Liu)
 
  - Enhancements to the PCI hot reset interface in support of cdev usage.
    (Yi Liu)
 
  - Fix a potential race between registering and unregistering vfio files
    in the kvm-vfio interface and extend use of a lock to avoid extra
    drop and acquires. (Dmitry Torokhov)

f8fd5c2483 This pull request is full of clk driver changes. In fact, there aren't any 
changes to the clk framework this time around. That's probably because everyone
 was on vacation (yours truly included). We did lose a couple clk drivers this
 time around because nobody was using those devices. That skews the diffstat a
 bit, but either way, nothing looks out of the ordinary here. The usual suspects
 are chugging along adding support for more SoCs and fixing bugs.
 
 If I had to choose, I'd say the theme for the past few months has been
 "polish". There's quite a few patches that migrate to
 devm_platform_ioremap_resource() in here. And there's more than a handful of
 patches that move the NR_CLKS define from the DT binding header to the driver.
 There's even patches that migrate drivers to use clk_parent_data and clk_hw to
 describe clk tree topology. It seems that the spring (summer?) cleaning bug got
 some folks, or the semiconductor shortage finally hit the software side.
 
 New Drivers:
  - StarFive JH7110 SoC clock drivers
  - Qualcomm IPQ5018 Global Clock Controller driver
  - Versa3 clk generator to support 48KHz playback/record with audio codec on
    RZ/G2L SMARC EVK
 
 Removed Drivers:
  - Remove non-OF mmp clk drivers
  - Remove OXNAS clk driver
 
 Updates:
  - Add __counted_by to struct clk_hw_onecell_data and struct spmi_pmic_div_clk_cc
  - Move defines for numbers of clks (NR_CLKS) from DT headers to drivers
  - Introduce kstrdup_and_replace() and use it
  - Add PLL rates for Rockchip rk3568
  - Add the display clock tree for Rockchip rv1126
  - Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and RZ/G2 SoCs
  - Convert sun9i-mmc clock to use devm_platform_get_and_ioremap_resource()
  - Fix function name in a comment in ccu_mmc_timing.c
  - Parameter name correction for ccu_nkm_round_rate()
  - Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e. consider alternative
    parent rates when determining clock rates
  - Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
  - Support finding closest (as opposed to closest but not higher) clock rate
    for NM, NKM, mux and div type clocks, as use it for Allwinner A64 pll-video0
  - Prefer current parent rate if able to generate ideal clock rate for Allwinner NKM clocks
  - Clean up Qualcomm SMD RPM driver, with interconnect bus clocks moved out to
    the interconnect drivers
  - Fix various PM runtime bugs across many Qualcomm clk drivers
  - Migrate Qualcomm MDM9615 is to parent_hw and parent_data
  - Add network related resets on Qualcomm IPQ4019
  - Add a couple missing USB related clocks to Qualcomm IPQ9574
  - Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock controller
  - In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs, and GPLL1 are
    added, while PCIe pipe clock, SDCC rcg ops are corrected
  - Add missing GDSCs to and correct GDSCs for the SC8280XP global clock controller driver
  - Support retention for the Qualcomm SC8280XP display clock controller GDSCs.
  - Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE to fix
    issues with missing parent clocks across sc7180, sm7150, sm6350 and sm8250,
    while sm8450 is corrected to use floor ops
  - Correct Qualcomm SM6350 GPU clock controller's clock supplies
  - Drop unwanted clocks from the Qualcomm IPQ5332 GCC driver
  - Add missing OXILICX GDSC to Qualcomm MSM8226 GCC
  - Change the delay in the Qualcomm reset controller to fsleep() for correctness
  - Extend the Qualcomm SM83550 Video clock controller to support SC8280XP
  - Add graphics clock support on Renesas RZ/G2M, RZ/G2N, RZ/G2E, and R-Car H3,
    M3-W, and M3-N SoCs
  - Add Clocked Serial Interface (CSI) clocks on Renesas RZ/V2M
  - Add PWM (MTU3) clock and reset on Renesas RZ/G2UL and RZ/Five
  - Add the PDM IPC clock for i.MX93
  - Add 519.75MHz frequency support for i.MX9 PLL
  - Simplify the .determine_rate() implementation for i.MX GPR mux
  - Make the i.MX8QXP LPCG clock use devm_platform_ioremap_resource()
  - Add the audio mux clock to i.MX8
  - Fix the SPLL2 MULT range for PLLv4
  - Update the SPLL2 type in i.MX8ULP
  - Fix the SAI4 clock on i.MX8MP

  - Drop restrictions for i.MX PLL14xx and fix its max prediv value
  - Drop the 393216000 and 361267200 from i.MX PLL14xx rate table to allow
    glitch free switching

8f447694c2 Devicetree updates for v6.6: 
DT core:
 - Add support for generating DT nodes for PCI devices. This is the
   groundwork for applying overlays to PCI devices containing
   non-discoverable downstream devices.
 
 - DT unittest additions to check reverted changesets, to test for
   refcount issues, and to test unresolved symbols. Also, various
   clean-ups of the unittest along the way.
 
 - Refactor node and property manipulation functions to better share code
   with old API and changeset API
 
 - Refactor changeset print functions to a common implementation
 
 - Move some platform_device specific functions into of_platform.c
 
 Bindings:
 - Treewide fixing of typos
 
 - Treewide clean-up of SPDX tags to use 'OR' consistently
 
 - Last chunk of dropping unnecessary quotes. With that, the check
   for unnecessary quotes is enabled in yamllint.
 
 - Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
   bindings to DT schema format
 
 - Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450 Inline
   Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt controller,
   Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings

Pull devicetree updates from Rob Herring:
 "DT core:

   - Add support for generating DT nodes for PCI devices. This is the
     groundwork for applying overlays to PCI devices containing
     non-discoverable downstream devices.

   - DT unittest additions to check reverted changesets, to test for
     refcount issues, and to test unresolved symbols. Also, various
     clean-ups of the unittest along the way.

   - Refactor node and property manipulation functions to better share
     code with old API and changeset API

   - Refactor changeset print functions to a common implementation

   - Move some platform_device specific functions into of_platform.c

  Bindings:

   - Treewide fixing of typos

   - Treewide clean-up of SPDX tags to use 'OR' consistently

   - Last chunk of dropping unnecessary quotes. With that, the check for
     unnecessary quotes is enabled in yamllint.

   - Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
     bindings to DT schema format

   - Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450
     Inline Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt
     controller, Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings

0e72db7767 ARM: devicetree updates for 6.6 
These are the devicetree updates for Arm and RISC-V based SoCs,
 mainly from Qualcomm, NXP/Freescale, Aspeed, TI, Rockchips,
 Samsung, ST and Starfive.
 
 Only a few new SoC got added:
 
  - TI AM62P5, a variant of the existing Sitara AM62x family
 
  - Intel Agilex5, an FPGFA platform that includes an
    Cortex-A76/A55 SoC.
 
  - Qualcomm ipq5018 is used in wireless access points
 
  - Qualcomm SM4450 (Snapdragon 4 Gen 2) is a new low-end mobile
    phone platform.
 
 In total, 29 machines get added, which is low because of the summer
 break. These cover SoCs from Aspeed, Broadcom, NXP, Samsung, ST,
 Allwinner, Amlogic, Intel, Qualcomm, Rockchip, TI and T-Head.  Most of
 these are development and reference boards.
 
 Despite not adding a lot of new machines, there are over 700 patches in
 total, most of which are cleanups and minor fixes.

1544df9ab4 ARM: SoC drivers for 6.6 
The main change this time is the introduction of the drivers/genpd
 subsystem that gets split out from drivers/soc to keep common
 functionality together. Ulf Hansson is taking over maintainership for
 these and is sending a separate pull request with the same commits,
 but they are in the soc drivers tree to avoid conflicts against other
 soc driver patches.
 
 The SCMI driver subsystem gets an update to version 3.2 of the
 specification. There are also updates to memory, reset and other firmware
 drivers.
 
 On the soc driver side, the updates are mostly cleanups across a number
 of Arm platforms. On driver for loongarch adds power management for DT
 based systems, another driver is for HiSilicon's Arm server chips with
 their HCCS system health interface.
 
 The remaining updates for the most part add support for additional
 hardware in existing drivers or contain minor cleanups. Most of these
 are for the Qualcomm Snapdragon platform.

53ea7f624f New code for 6.6: 
* Chandan Babu will be taking over as the XFS release manager.  He has
    reviewed all the patches that are in this branch, though I'm signing
    the branch one last time since I'm still technically maintainer. :P
  * Create a maintainer entry profile for XFS in which we lay out the
    various roles that I have played for many years.  Aside from release
    manager, the remaining roles are as yet unfilled.
  * Start merging online repair -- we now have in-memory pageable memory
    for staging btrees, a bunch of pending fixes, and we've started the
    process of refactoring the scrub support code to support more of
    repair.  In particular, reaping of old blocks from damaged structures.
  * Scrub the realtime summary file.
  * Fix a bug where scrub's quota iteration only ever returned the root
    dquot.  Oooops.
  * Fix some typos.

Pull io_uring updates from Jens Axboe:
 "Fairly quiet round in terms of features, mostly just improvements all
  over the map for existing code. In detail:

   - Initial support for socket operations through io_uring. Latter half
     of this will likely land with the 6.7 kernel, then allowing things
     like get/setsockopt (Breno)

   - Cleanup of the cancel code, and then adding support for canceling
     requests with the opcode as the key (me)

   - Improvements for the io-wq locking (me)

   - Fix affinity setting for SQPOLL based io-wq (me)

   - Remove the io_uring userspace code. These were added initially as
     copies from liburing, but all of them have since bitrotted and are
     way out of date at this point. Rather than attempt to keep them in
     sync, just get rid of them. People will have liburing available
     anyway for these examples. (Pavel)

   - Series improving the CQ/SQ ring caching (Pavel)

   - Misc fixes and cleanups (Pavel, Yue, me)"

    pressure.
 
  - Remove hard coded limitation on IPv6 specific info placement
    inside the socket struct.
 
  - Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated
    per socket scaling factor.
 
  - Scaling-up the IPv6 expired route GC via a separated list of
    expiring routes.
 
  - In-kernel support for the TLS alert protocol.
 
  - Better support for UDP reuseport with connected sockets.
 
  - Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
    header size.
 
  - Get rid of additional ancillary per MPTCP connection struct socket.
 
  - Implement support for BPF-based MPTCP packet schedulers.
 
  - Format MPTCP subtests selftests results in TAP.
 
  - Several new SMC 2.1 features including unique experimental options,
    max connections per lgr negotiation, max links per lgr negotiation.
 
 BPF
 ---
 
  - Multi-buffer support in AF_XDP.
 
  - Add multi uprobe BPF links for attaching multiple uprobes
    and usdt probes, which is significantly faster and saves extra fds.
 
  - Implement an fd-based tc BPF attach API (TCX) and BPF link support on
    top of it.
 
  - Add SO_REUSEPORT support for TC bpf_sk_assign.
 
  - Support new instructions from cpu v4 to simplify the generated code and
    feature completeness, for x86, arm64, riscv64.

  - Teach verifier actual bounds of bpf_get_smp_processor_id()
    and fix perf+libbpf issue related to custom section handling.
 
  - Introduce bpf map element count and enable it for all program types.
 
  - Add a BPF hook in sys_socket() to change the protocol ID
    from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy.
 
  - Introduce bpf_me_mcache_free_rcu() and fix OOM under stress.
 
  - Add uprobe support for the bpf_get_func_ip helper.
 
  - Check skb ownership against full socket.
 
  - Support for up to 12 arguments in BPF trampoline.
 
  - Extend link_info for kprobe_multi and perf_event links.
 
 Netfilter
 ---------
 
  - Speed-up process exit by aborting ruleset validation if a
    fatal signal is pending.
 
  - Allow NLA_POLICY_MASK to be used with BE16/BE32 types.
 
 Driver API
 ----------
 
  - Page pool optimizations, to improve data locality and cache usage.
 
  - Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
    for raw ioctl() handling in drivers.
 
  - Simplify genetlink dump operations (doit/dumpit) providing them
    the common information already populated in struct genl_info.
 
  - Extend and use the yaml devlink specs to [re]generate the split ops.
 
  - Introduce devlink selective dumps, to allow SF filtering SF based on
    handle and other attributes.

0119c894ab drm: Add initial ci/ subdirectory 
Developers can easily execute several tests on different devices
by just pushing their branch to their fork in a repository hosted
on gitlab.freedesktop.org which has an infrastructure to run jobs
in several runners and farms with different devices.

There are also other automated tools that uprev dependencies,
monitor the infra, and so on that are already used by the Mesa
project, and we can reuse them too.

Also, store expectations about what the DRM drivers are supposed
to pass in the IGT test suite. By storing the test expectations
along with the code, we can make sure both stay in sync with each
other so we can know when a code change breaks those expectations.

Also, include a configuration file that points to the out-of-tree
CI scripts.

This will allow all contributors to drm to reuse the infrastructure
already in gitlab.freedesktop.org to test the driver on several
generations of the hardware.

a031fe8d1d Rust changes for v6.6 
In terms of lines, most changes this time are on the pinned-init API
 and infrastructure. While we have a Rust version upgrade, and thus a
 bunch of changes from the vendored 'alloc' crate as usual, this time
 those do not account for many lines.
 
 Toolchain and infrastructure:
 
  - Upgrade to Rust 1.71.1. This is the second such upgrade, which is a
    smaller jump compared to the last time.
 
    This version allows us to remove the '__rust_*' allocator functions
    -- the compiler now generates them as expected, thus now our
    'KernelAllocator' is used.
 
    It also introduces the 'offset_of!' macro in the standard library
    (as an unstable feature) which we will need soon. So far, we were
    using a declarative macro as a prerequisite in some not-yet-landed
    patch series, which did not support sub-fields (i.e. nested structs):
 
        #[repr(C)]
        struct S {
            a: u16,
            b: (u8, u8),
        }
 
        assert_eq!(offset_of!(S, b.1), 3);
 
  - Upgrade to bindgen 0.65.1. This is the first time we upgrade its
    version.
 
    Given it is a fairly big jump, it comes with a fair number of
    improvements/changes that affect us, such as a fix needed to support
    LLVM 16 as well as proper support for '__noreturn' C functions, which
    are now mapped to return the '!' type in Rust:
 
        void __noreturn f(void); // C
        pub fn f() -> !;         // Rust
 
  - 'scripts/rust_is_available.sh' improvements and fixes.
 
    This series takes care of all the issues known so far and adds a few
    new checks to cover for even more cases, plus adds some more help
    texts. All this together will hopefully make problematic setups
    easier to identify and to be solved by users building the kernel.
 
    In addition, it adds a test suite which covers all branches of the
    shell script, as well as tests for the issues found so far.
 
  - Support rust-analyzer for out-of-tree modules too.
 
  - Give 'cfg's to rust-analyzer for the 'core' and 'alloc' crates.
 
  - Drop 'scripts/is_rust_module.sh' since it is not needed anymore.
 
 Macros crate:
 
  - New 'paste!' proc macro.
 
    This macro is a more flexible version of 'concat_idents!': it allows
    the resulting identifier to be used to declare new items and it
    allows to transform the identifiers before concatenating them, e.g.
 
        let x_1 = 42;
        paste!(let [<x _2>] = [<x _1>];);
        assert!(x_1 == x_2);
 
    The macro is then used for several of the pinned-init API changes in
    this pull.
 
 Pinned-init API:
 
  - Make '#[pin_data]' compatible with conditional compilation of fields,
    allowing to write code like:
 
        #[pin_data]
        pub struct Foo {
            #[cfg(CONFIG_BAR)]
            a: Bar,
            #[cfg(not(CONFIG_BAR))]
            a: Baz,
        }
 
  - New '#[derive(Zeroable)]' proc macro for the 'Zeroable' trait, which
    allows 'unsafe' implementations for structs where every field
    implements the 'Zeroable' trait, e.g.:
 
        #[derive(Zeroable)]
        pub struct DriverData {
            id: i64,
            buf_ptr: *mut u8,
            len: usize,
        }
 
  - Add '..Zeroable::zeroed()' syntax to the 'pin_init!'  macro for
    zeroing all other fields, e.g.:
 
        pin_init!(Buf {
            buf: [1; 64],
            ..Zeroable::zeroed()
        });
 
  - New '{,pin_}init_array_from_fn()' functions to create array
    initializers given a generator function, e.g.:
 
        let b: Box<[usize; 1_000]> = Box::init::<Error>(
            init_array_from_fn(|i| i)
        ).unwrap();
 
        assert_eq!(b.len(), 1_000);
        assert_eq!(b[123], 123);
 
  - New '{,pin_}chain' methods for '{,Pin}Init<T, E>' that allow to
    execute a closure on the value directly after initialization, e.g.:
 
        let foo = init!(Foo {
            buf <- init::zeroed()
        }).chain(|foo| {
            foo.setup();
            Ok(())
        });
 
  - Support arbitrary paths in init macros, instead of just identifiers
    and generic types.
 
  - Implement the 'Zeroable' trait for the 'UnsafeCell<T>' and
    'Opaque<T>' types.
 
  - Make initializer values inaccessible after initialization.
 
  - Make guards in the init macros hygienic.
 
 'allocator' module:
 
  - Use 'krealloc_aligned()' in 'KernelAllocator::alloc' preventing
    misaligned allocations when the Rust 1.71.1 upgrade is applied later
    in this pull.
 
    The equivalent fix for the previous compiler version (where
    'KernelAllocator' is not yet used) was merged into 6.5 already,
    which added the 'krealloc_aligned()' function used here.
 
  - Implement 'KernelAllocator::{realloc, alloc_zeroed}' for performance,
    using 'krealloc_aligned()' too, which forwards the call to the C API.
 
 'types' module:
 
  - Make 'Opaque' be '!Unpin', removing the need to add a 'PhantomPinned'
    field to Rust structs that contain C structs which must not be moved.
 
  - Make 'Opaque' use 'UnsafeCell' as the outer type, rather than inner.
 
 Documentation:
 
  - Suggest obtaining the source code of the Rust's 'core' library using
    the tarball instead of the repository.

    as reviewers of the "RUST" entry.

1c59d38339 linux-kselftest-nolibc-6.6-rc1 
This nolibc update for Linux 6.6-rc1 consists of:
 
 Nolibc:
   - improved portability by removing build errors with -ENOSYS
   - added syscall6() on MIPS to support pselect6() and mmap()
   - added setvbuf(), rmdir(), pipe(), pipe2()
   - add support for ppc/ppc64
   - environ is no longer optional
   - fixed frame pointer issues at -O0
   - dropped sys_stat() in favor of sys_statx()
   - centralized _start_c() to remove lots of asm code
   - switched size_t to __SIZE_TYPE__
 
 Selftests:
   - improved status reporting (success/warning/failure counts,
     path to log file)
   - various code cleanups (indent, unused variables, ...)
   - more consistent test numbering
   - enabled compiler warnings
   - dropped unreliable chmod_net test
   - improved reliability (create /dev/zero & /tmp, rely less on /proc)
   - new tests (brk/sbrk/mmap/munmap)
   - improved compatibility with musl
   - new run-nolibc-test target to build and run natively
   - new run-libc-test target to build and run against native libc
   - made the cmdline parser more reliable against boolean arguments
   - dropped dependency on memfd for vfprintf() test
   - nolibc-test is no longer stripped
   - added support for extending ARCH via XARCH
