 "The big change here is obviously the revert of the pktcdvd driver

   - Fix for splitting of a bio marked as NOWAIT, causing either nowait
     reads or writes to error with EAGAIN even if parts of the IO
     completed (me)

There are apparently still users out there of this driver. While we'd
love to remove it to ease the maintenance burden, let's reinstate it
for now until better (userspace) solutions can be developed.

This adds a document about what specification features are supported by
the Linux NVMe driver, and what qualifies for a quirk if an implementation
has problems following the specification.

Commit a789aeba41 ("KVM: VMX: Rename "vmx/evmcs.{ch}" to
"vmx/hyperv.{ch}"") renames the VMX specific Hyper-V files, but does not
adjust the entry in MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Repair this file reference in KVM X86 HYPER-V (KVM/hyper-v).

158738ea75 Update to zstd-1.5.2
The major goal of this PR is to update the kernel to upstream zstd v1.5.2 [0].
 Specifically to the tag v1.5.2-kernel [1] which includes several cherrypicked
 fixes for the kernel on top of v1.5.2.
 
 Excepting the MAINTAINERS change, all the changes in this PR can be generated by:
 
 ```
 git clone https://github.com/facebook/zstd
 cd zstd/contrib/linux-kernel
 git checkout v1.5.2-kernel
 LINUX=/path/to/linux/repo make import
 ```
 
 These changes have been baking in linux-next since 2022/10/24 when I put up
 my patchset [2]. Notably the first commit is a small refactor of the only zstd
 commit since the last update [3] to fit the upstream import scheme.
 
 Additionally, this PR includes several minor typo fixes, which have all been
 fixed upstream so they are maintained on the next import.

aa4800e31c perf tools changes for v6.2: 1st batch
Libraries:
 
 - Drop the old copy of libtraceevent in tools/lib/traceevent/ now that all major distros
   ship it from its external repository.
 
   This is now just another feature detection, emitting a warning when the
   libtraceevent-dev[el] package isn't installed, disabling the build of perf features
   and tools that strictly require parsing things from tracefs while keeping
   the core functionality present and working with a subset of the events, the
   most used ones like CPU cycles, hardware cache and also vendor events, etc.
 
   This was tested with lots of containers for Fedora, Debian, OpenSUSE, Alpine Linux,
   Ubuntu, with cross builds, etc.
 
 Build:
 
 - Update to C standard to gnu11, like was done for the kernel.
 
 - Install the tools/lib/ libraries locally instead of having headers searched
   directly from the source code directories, to help the cases where we can
   build either from in-kernel source libraries or from the same library shipped
   as a distro package, as is the case with libbpf and was the case with
   libtraceevent.
 
 perf stat:
 
 - Do not delay the workload with --delay, the delay is just for starting to count
   the events, to skip noise at workload startup.
 
 - When we have events for each cgroup, the metric should be printed for each
   cgroup separately.
 
   $ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1
 
    Performance counter stats for 'system wide':
 
                    GHz  insn per cycle  branch-misses of all branches
    system.slice  3.792      0.61                  3.24%
    user.slice    3.661      2.32                  0.37%
 
 - Fix printing field separator in CSV metrics output.
 
 - Fix --metric-only --json output.
 
 - Fix summary output in CSV with --metric-only.
 
 - Update event group check for support of uncore event.
 
 perf test:
 
 - Stop requiring a C toolchain in shell tests, instead add a workload option that has
   all the previously C snippets built as part of 'perf test -w' that then get used in
   the 'perf test' shell scripts.
 
 - Add event group test for events in multiple PMUs
 
 - The "kernel lock contention analysis" test should not print warnings in quiet mode.
 
 - Add attr tests for ARM64's new VG register.
 
 - Fix record test on KVM guests, as using precise flag with the
   br_inst_retired.near_call event causes the test fail on KVM guests, even when
   the guests have PMU forwarding enabled and the event itself is supported, so just
   remove the precise flag from the event.
 
 - Add mechanism for skipping attr tests on specific kernel versions where it is known that
   these checks will fail.
 
 - Skip watchpoint tests if no watchpoints available.
 
 - Add more Intel PT 'perf test' entries: hybrid CPUs, split the packet decoder
   into a suite of subtests.
 
 perf script:
 
 - Introduce task analyzer python script, where one first records some events:
 
 Recording can be done in two ways:
 
   $ perf script record tasks-analyzer -- sleep 10
   $ perf record -e sched:sched_switch -a -- sleep 10
 
 The script can parse any perf.data files, as long as it has sched:sched_switch events,
 other events will be ignored.
 
 The most simple report use case is to just call the script without arguments.
 
 Runtime is the time the task was running on the CPU, Time Out-In is the time
 between the process being scheduled *out* and scheduled back *in*. So the last
 time span between two executions:
 
   $ perf script report tasks-analyzer
       Switched-In     Switched-Out CPU    PID    TID             Comm  Runtime  Time Out-In

   [...]
 
 perf lock:
 
 - Allow concurrent record and report to support live monitoring of kernel lock
   contention without BPF:
 
   # perf lock record -a -o- sleep 1 | perf lock contention -i-
    contended   total wait     max wait     avg wait         type   caller

            1      436 ns    436 ns    436 ns  ffff9260bfda4f60
 
 perf record:
 
 - Add remaining branch filters: "no_cycles", "no_flags" & "hw_index", to be
   used with hardware such as Intel's LBR that allows things like stitching
   stacks of two samples to overcome the limits of the number of LBR registers.
 
 Symbol resolution:
 
 - Handle .debug files created with 'objcopy --only-keep-debug', where program
   headers are zeroed and thus can't be used for adjustments, use the info in
   the runtime_ss (runtime ELF) instead.
 
 perf trace:
 
 - Add BPF based augmenter for the 'perf_event_open's 'struct perf_event_attr' argument.
 
 - Add BPF based augmenter for the 'clock_gettime's 'struct timespec' argument.
 
 - In both cases the syscall tracepoint has just the pointer value, we
   need to hook a BPF program to collect the pointer contents, and then,
   in userspace, pretty print it in 'perf trace'.
 
 perf list:
 
 - Introduce JSON output of events.
 
 - Streamline how the expression specifying what events should be shown is handled,
   fixing several corner cases, such as the metric filter that is specified as a glob
   but was using strstr().
 
 perf probe:
 
 - Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang generating
   DWARF5 like that.
 
 - Use dwarf_attr_integrate() as generic DWARF attr accessor as it supersedes dwarf_attr(),
   supporting abstact origin DIEs.
 
 perf inject:
 
 - Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID so that
   perf.data readers can get the real build-id size and avoid trailing zeros.
 
 perf data:
 
 - Add tracepoint fields when converting a perf.data file to JSON.
 
 arm64:
 
 - Fix mksyscalltbl, don't lose syscalls due to sort -nu.
 
 - Add Arm Neoverse V2 PMU events.
 
 riscv:
 
 - Add riscv sbi firmware std event files.
 
 - Add Sifive U74 vendor events (JSON) file.
 
 - Add some more events and metrics for Alderlake/Alderlake-N.
 
 Documentation:
 
 - Add data documentation for the PMU structs in the C source code.
 
 Miscellaneous:
 
 - Periodic sanitization of headers, adding missing includes, removing needless ones,
   creating new ones, etc.
 
 - Use sig_atomic_t for signal handlers to avoid undefined behaviour in all perf
   tools.
 
 - Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF examples.
 
 - Remove some old perf bpf examples, leave the best ones that demonstrate how
   to associate BPF functions to points in the kernel.
 
 - Make quiet mode consistent between tools.
 
 - Use dedicated non-atomic clear/set bit helpers.
 
 - Use "grep -E" instead of "egrep" as recommended by warning emitted by GNU
   grep since at least version 3.8.
 
 - Complete list of supported subcommands in the 'perf daemon' help message.
 
 - Update John Garry's email address for arm64 perf tooling on the MAINTAINERS file,
   he moved from Huawei to Oracle.

  perf lock:

   - Allow concurrent record and report to support live monitoring of
     kernel lock contention without BPF:

         contended   total wait     max wait     avg wait         type   caller

   - Implement -t/--threads option when using BPF:

  perf record:

   - Add remaining branch filters: "no_cycles", "no_flags" & "hw_index",
     to be used with hardware such as Intel's LBR that allows things
     like stitching stacks of two samples to overcome the limits of the
     number of LBR registers.

  Symbol resolution:

   - Handle .debug files created with 'objcopy --only-keep-debug', where
     program headers are zeroed and thus can't be used for adjustments,
     use the info in the runtime_ss (runtime ELF) instead.

  perf trace:

   - Add BPF based augmenter for the 'perf_event_open's 'struct
     perf_event_attr' argument.

   - Add BPF based augmenter for the 'clock_gettime's 'struct timespec'
     argument.

   - In both cases the syscall tracepoint has just the pointer value, we
     need to hook a BPF program to collect the pointer contents, and
     then, in userspace, pretty print it in 'perf trace'.

  perf list:

   - Introduce JSON output of events.

   - Streamline how the expression specifying what events should be
     shown is handled, fixing several corner cases, such as the metric
     filter that is specified as a glob but was using strstr().

  perf probe:

   - Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang
     generating DWARF5 like that.

   - Use dwarf_attr_integrate() as generic DWARF attr accessor as it
     supersedes dwarf_attr(), supporting abstact origin DIEs.

  perf inject:

   - Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID
     so that perf.data readers can get the real build-id size and avoid
     trailing zeroes.

  perf data:

   - Add tracepoint fields when converting a perf.data file to JSON.

  arm64:

   - Fix mksyscalltbl, don't lose syscalls due to sort -nu.

   - Add Arm Neoverse V2 PMU events.

  riscv:

   - Add riscv sbi firmware std event files.

   - Add Sifive U74 vendor events (JSON) file.

   - Add some more events and metrics for Alderlake/Alderlake-N.

  Documentation:

   - Add data documentation for the PMU structs in the C source code.

  Miscellaneous:

   - Periodic sanitization of headers, adding missing includes, removing
     needless ones, creating new ones, etc.

   - Use sig_atomic_t for signal handlers to avoid undefined behaviour
     in all perf tools.

   - Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF
     examples.

   - Remove some old perf bpf examples, leave the best ones that
     demonstrate how to associate BPF functions to points in the kernel.

   - Make quiet mode consistent between tools.

   - Use dedicated non-atomic clear/set bit helpers.

   - Use "grep -E" instead of "egrep" as recommended by warning emitted
     by GNU grep since at least version 3.8.

   - Complete list of supported subcommands in the 'perf daemon' help
     message.

   - Update John Garry's email address for arm64 perf tooling on the
     MAINTAINERS file, he moved from Huawei to Oracle"

ba54ff1fb6 Char/Misc driver changes for 6.2-rc1
Here is the large set of char/misc and other driver subsystem changes
 for 6.2-rc1.  Nothing earth-shattering in here at all, just a lot of new
 driver development and minor fixes.  Highlights include:
  - fastrpc driver updates
  - iio new drivers and updates
  - habanalabs driver updates for new hardware and features
  - slimbus driver updates
  - speakup module parameters added to aid in boot time configuration
  - i2c probe_new conversions for lots of different drivers
  - other small driver fixes and additions
 
 One semi-interesting change in here is the increase of the number of
 misc dynamic minors available to 1048448 to handle new huge-cpu systems.
 
 All of these have been in linux-next for a while with no reported
 problems.

58bcac11fd USB/Thunderbolt driver changes for 6.2-rc1
Here is the large set of USB and Thunderbolt driver changes for 6.2-rc1.
 Overall, thanks to the removal of a driver, more lines were removed than
 added, a nice change.  Highlights include:
   - removal of the sisusbvga driver that was not used by anyone anymore
   - minor thunderbolt driver changes and tweaks
   - chipidea driver updates
   - usual set of typec driver features and hardware support added
   - musb minor driver fixes
   - fotg210 driver fixes, bringing that hardware back from the "dead"
   - minor dwc3 driver updates
   - addition, and then removal, of a list.h helper function for many USB
     and other subsystem drivers, that ended up breaking the build.  That
     will come back for 6.3-rc1, it missed this merge window.
   - usual xhci updates and enhancements
   - usb-serial driver updates and support for new devices
   - other minor USB driver updates

fe36bb8736 Tracing updates for 6.2:
- Add options to the osnoise tracer
   o panic_on_stop option that panics the kernel if osnoise is greater than some
     user defined threshold.
   o preempt option, to test noise while preemption is disabled
   o irq option, to test noise when interrupts are disabled
 
 - Add .percent and .graph suffix to histograms to give different outputs
 
 - Add nohitcount to disable showing hitcount in histogram output
 
 - Add new __cpumask() to trace event fields to annotate that a unsigned long
   array is a cpumask to user space and should be treated as one.
 
 - Add trace_trigger kernel command line parameter to enable trace event
   triggers at boot up. Useful to trace stack traces, disable tracing and take
   snapshots.
 
 - Fix x86/kmmio mmio tracer to work with the updates to lockdep
 
 - Unify the panic and die notifiers
 
 - Add back ftrace_expect reference that is used to extract more information in
   the ftrace_bug() code.
 
 - Have trigger filter parsing errors show up in the tracing error log.
 
 - Updated MAINTAINERS file to add kernel tracing  mailing list and patchwork
   info
 
 - Use IDA to keep track of event type numbers.

In this round, we've added two features: 1) F2FS_IOC_START_ATOMIC_REPLACE and
 2) per-block age-based extent cache. 1) is a variant of the previous atomic
 write feature which guarantees a per-file atomicity. It would be more efficient
 than AtomicFile implementation in Android framework. 2) implements another type
 of extent cache in memory which keeps the per-block age in a file, so that block
 allocator could split the hot and cold data blocks more accurately.
 
 Enhancement:
  - introduce F2FS_IOC_START_ATOMIC_REPLACE
  - refactor extent_cache to add a new per-block-age-based extent cache support
  - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs
  - add proc entry to show discard_plist info
  - optimize iteration over sparse directories
  - add barrier mount option
 
 Bug fix
  - avoid victim selection from previous victim section
  - fix to enable compress for newly created file if extension matches
  - set zstd compress level correctly
  - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot
  - correct i_size change for atomic writes
  - allow to read node block after shutdown
  - allow to set compression for inlined file
  - fix gc mode when gc_urgent_high_remaining is 1
  - should put a page when checking the summary info
 
 Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc.

48ea09cdda hardening updates for v6.2-rc1
- Convert flexible array members, fix -Wstringop-overflow warnings,
   and fix KCFI function type mismatches that went ignored by
   maintainers (Gustavo A. R. Silva, Nathan Chancellor, Kees Cook).
 
 - Remove the remaining side-effect users of ksize() by converting
   dma-buf, btrfs, and coredump to using kmalloc_size_roundup(),
   add more __alloc_size attributes, and introduce full testing
   of all allocator functions. Finally remove the ksize() side-effect
   so that each allocation-aware checker can finally behave without
   exceptions.
 
 - Introduce oops_limit (default 10,000) and warn_limit (default off)
   to provide greater granularity of control for panic_on_oops and
   panic_on_warn (Jann Horn, Kees Cook).
 
 - Introduce overflows_type() and castable_to_type() helpers for
   cleaner overflow checking.
 
 - Improve code generation for strscpy() and update str*() kern-doc.
 
 - Convert strscpy and sigphash tests to KUnit, and expand memcpy
   tests.
 
 - Always use a non-NULL argument for prepare_kernel_cred().
 
 - Disable structleak plugin in FORTIFY KUnit test (Anders Roxell).
 
 - Adjust orphan linker section checking to respect CONFIG_WERROR
   (Xin Li).
 
 - Make sure siginfo is cleared for forced SIGKILL (haifeng.xu).
 
 - Fix um vs FORTIFY warnings for always-NULL arguments.
