ec963d04ca pinctrl: provide new GPIO-to-pinctrl glue helpers 
Currently the pinctrl GPIO helpers all take a number from the global
GPIO numberspace - of which we're trying to get rid of as argument.

These helpers are almost universally called from GPIOLIB driver
callbacks which take a pointer to the backing gpio_chip and the
controller-relative offset as arguments.

Let's provide improved variants of these functions that match the
GPIOLIB signatures as the first step in removing the older flavor.

2c40c1c6ad USB/Thunderbolt changes for 6.7-rc1 
Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
 Nothing really major in here, just lots of constant development for new
 hardware.  Included in here are:
   - Thunderbolt (i.e. USB4) fixes for reported issues and support for
     new hardware types and devices
   - USB typec additions of new drivers and cleanups for some existing
     ones
   - xhci cleanups and expanded tracing support and some platform
     specific updates
   - USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi,
     and i2c drivers for that type of device (all acked by the respective
     subsystem maintainers.)
   - lots of USB gadget driver updates and cleanups
   - new USB dwc3 platforms supported, as well as other dwc3 fixes and
     cleanups
   - USB chipidea driver updates
   - other smaller driver cleanups and additions, full details in the
     shortlog
 
 All of these have been in the linux-next tree for a while with no
 reported problems, EXCEPT for some merge conflicts that you will run
 into in your tree.  2 of them are in device-tree files, which will be
 trivial to resolve (accept both sides), and the last in the
 drivers/gpio/gpio-ljca.c file, in the remove callback, resolution should
 be pretty trivial (take the version in this branch), see here:
 	https://lore.kernel.org/all/20231016134159.11d8f849@canb.auug.org.au/
 for details, or I can provide a resolved merge point if needed.

4c7a0c95ad Staging driver updates for 6.7-rc1 
Here is the big set of staging driver updates for 6.7-rc1.  A bit bigger
 than 6.6 this time around, as it coincided with the Outreachy and
 mentorship application process, so we got a bunch of new developers
 sending in their first changes, which is nice to see.
 
 Also in here is a removal of the qlge ethernet driver, and the rtl8192u
 wireless driver.  Both of these were very old and no one was maintaining
 them, the wireless driver removal was due to no one using it anymore,
 and no hardware to be found, and is part of a larger effort to remove
 unused and old wifi drivers from the system.
 
 The qlge ethernet driver did have one user pop up after it was dropped,
 and we are working with the network mainainers to figure out what tree
 it will come back in from and who will be responsible for it, and if it
 really is being used or not.  Odds are it will show up in a network
 subsystem pull request after -rc1 is out, but we aren't sure yet.
 
 Other smaller changes in here are:
   - Lots of vc04_services work by Umang to clean up the mess created by
     the rpi developers long ago, bringing it almost into good enough
     shape to get out of staging, hopefully next major release, it's
     getting close.
   - rtl8192e variable cleanups and removal of unused code and structures
   - vme_user coding style cleanups
   - other small coding style cleanups to lots of the staging drivers
   - octeon typedef removals, and then last-minute revert when it was
     found to break the build in some configurations (it's a hard driver
     to build properly, none of the normal automated testing catches it.)
 
 All of these have been in linux-next for a while with no reported
 issues.

Pull apparmor updates from John Johansen:
 "This adds initial support for mediating io_uring and userns creation.
  Adds a new restriction that tightens the use of change_profile, and a
  couple of optimizations to reduce performance bottle necks that have
  been found when retrieving the current task's secid and allocating
  work buffers.

  The majority of the patch set continues cleaning up and simplifying
  the code (fixing comments, removing now dead functions, and macros
  etc). Finally there are 4 bug fixes, with the regression fix having
  had a couple months of testing.

  Features:
   - optimize retrieving current task secid
   - add base io_uring mediation
   - add base userns mediation
   - improve buffer allocation
   - allow restricting unprivilege change_profile

  Cleanups:
   - Fix kernel doc comments
   - remove unused declarations
   - remove unused functions
   - remove unneeded #ifdef
   - remove unused macros
   - mark fns static
   - cleanup fn with unused return values

Merge tag 'landlock-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux

Pull landlock updates from Mickaël Salaün:
 "A Landlock ruleset can now handle two new access rights:
  LANDLOCK_ACCESS_NET_BIND_TCP and LANDLOCK_ACCESS_NET_CONNECT_TCP. When
  handled, the related actions are denied unless explicitly allowed by a
  Landlock network rule for a specific port.

  The related patch series has been reviewed for almost two years, it
  has evolved a lot and we now have reached a decent design, code and
  testing. The refactored kernel code and the new test helpers also
  bring the foundation to support more network protocols.

  Test coverage for security/landlock is 92.4% of 710 lines according to
  gcc/gcov-13, and it was 93.1% of 597 lines before this series. The
  decrease in coverage is due to code refactoring to make the ruleset
  management more generic (i.e. dealing with inodes and ports) that also
  added new WARN_ON_ONCE() checks not possible to test from user space.

  syzkaller has been updated accordingly [4], and such patched instance
  (tailored to Landlock) has been running for a month, covering all the
  new network-related code [5]"

7ab89417ed perf tools changes for v6.7 
Build
 -----
 * Compile BPF programs by default if clang (>= 12.0.1) is available to
   enable more features like kernel lock contention, off-cpu profiling,
   kwork, sample filtering and so on.  It can be disabled by passing
   BUILD_BPF_SKEL=0 to make.
 
 * Produce better error messages for bison on debug build (make DEBUG=1)
   by defining YYDEBUG symbol internally.
 
 perf record
 -----------
 * Track sideband events (like FORK/MMAP) from all CPUs even if perf record
   targets a subset of CPUs only (using -C option).  Otherwise it may lose
   some information happened on a CPU out of the target list.
 
 * Fix checking raw sched_switch tracepoint argument using system BTF.
   This affects off-cpu profiling which attaches a BPF program to the raw
   tracepoint.
 
 perf lock contention
 --------------------
 * Add --lock-cgroup option to see contention by cgroups.  This should be
   used with BPF only (using -b option).
 
     $ sudo perf lock con -ab --lock-cgroup -- sleep 1
      contended   total wait     max wait     avg wait   cgroup
 
            835     14.06 ms     41.19 us     16.83 us   /system.slice/led.service
             25    122.38 us     13.77 us      4.89 us   /

              1       491 ns       491 ns       491 ns   /system.slice/connectd.service
 
 * Add -G/--cgroup-filter option to see contention only for given cgroups.
   This can be useful when you identified a cgroup in the above command and
   want to investigate more on it.  It also works with other output options
   like -t/--threads and -l/--lock-addr.
 
     $ sudo perf lock con -ab -G /user.slice/user-657345.slice/session-c4.scope -- sleep 1
      contended   total wait     max wait     avg wait         type   caller

 * Use per-cpu array for better spinlock tracking.  This is to improve
   performance of the BPF program and to avoid nested contention on a lock
   in the BPF hash map.
 
 * Update callstack check for PowerPC.  To find a representative caller of a
   lock, it needs to look up the call stacks.  It ends the lookup when it sees
   0 in the call stack buffer.  However, PowerPC call stacks can have 0 values
   in the beginning so skip them when it expects valid call stacks after.
 
 perf kwork
 ----------
 * Support 'sched' class (for -k option) so that it can see task scheduling
   event (using sched_switch tracepoint) as well as irq and workqueue items.
 
 * Add perf kwork top subcommand to show more accurate cpu utilization with
   sched class above.  It works both with a recorded data (using perf kwork
   record command) and BPF (using -b option).  Unlike perf top command, it
   does not support interactive mode (yet).
 
     $ sudo perf kwork top -b -k sched
     Starting trace, Hit <Ctrl+C> to stop and report

 perf bench
 ----------
 * Add -G/--cgroups option to perf bench sched pipe.  The pipe bench is
   good to measure context switch overhead.  With this option, it puts
   the reader and writer tasks in separate cgroups to enforce context
   switch between two different cgroups.
 
   Also it needs to set CPU affinity of the tasks in a CPU to accurately
   measure the impact of cgroup context switches.
 
     $ sudo perf stat -e context-switches,cgroup-switches -- \
     > taskset -c 0 perf bench sched pipe -l 100000
     # Running 'sched/pipe' benchmark:
     # Executed 100000 pipe operations between two processes
 
          Total time: 0.307 [sec]
 
            3.078180 usecs/op
              324867 ops/sec
 
      Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000':
 
                200,026      context-switches
                     63      cgroup-switches
 
            0.321637922 seconds time elapsed
 
   You can see small number of cgroup-switches because both write and read
   tasks are in the same cgroup.
 
     $ sudo mkdir /sys/fs/cgroup/{AAA,BBB}
 
     $ sudo perf stat -e context-switches,cgroup-switches -- \
     > taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB
     # Running 'sched/pipe' benchmark:
     # Executed 100000 pipe operations between two processes
 
          Total time: 0.351 [sec]
 
            3.512990 usecs/op
              284657 ops/sec
 
      Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB':
 
                200,020      context-switches
                200,019      cgroup-switches
 
            0.365034567 seconds time elapsed
 
   Now context-switches and cgroup-switches are almost same.  And you can
   see the pipe operation took little more.
 
 * Kill child processes when perf bench sched messaging exited abnormally.
   Otherwise it'd leave the child doing unnecessary work.
 
 perf test
 ---------
 * Fix various shellcheck issues on the tests written in shell script.
 
 * Skip tests when condition is not satisfied:
   - object code reading test for non-text section addresses.
   - CoreSight test if cs_etm// event is not available.
   - lock contention test if not enough CPUs.
 
 Event parsing
 -------------
 * Make PMU alias name loading lazy to reduce the startup time in the
   event parsing code for perf record, stat and others in the general
   case.
 
 * Lazily compute PMU default config.  In the same sense, delay PMU
   initialization until it's really needed to reduce the startup cost.
 
 * Fix event term values that are raw events.  The event specification
   can have several terms including event name.  But sometimes it clashes
   with raw event encoding which starts with 'r' and has hex-digits.
 
   For example, an event named 'read' should be processed as a normal
   event but it was mis-treated as a raw encoding and caused a failure.
 
     $ perf stat -e 'uncore_imc_free_running/event=read/' -a sleep 1
     event syntax error: '..nning/event=read/'
                                       \___ parser error
     Run 'perf list' for a list of valid events
 
      Usage: perf stat [<options>] [<command>]
 
         -e, --event <event> event selector. use 'perf list' to list available events
 
 Event metrics
 -------------
 * Add "Compat" regex to match event with multiple identifiers.
 
 * Usual updates for Intel, Power10, Arm telemetry/CMN and AmpereOne.
 
 Misc
 ----
 * Assorted memory leak fixes and footprint reduction.
 
 * Add "bpf_skeletons" to perf version --build-options so that users can
   check whether their perf tools have BPF support easily.
 
 * Fix unaligned access in Intel-PT packet decoder found by undefined-behavior
   sanitizer.
 
 * Avoid frequency mode for the dummy event.  Surprisingly it'd impact
   kernel timer tick handler performance by force iterating all PMU events.
 
 * Update bash shell completion for events and metrics.

Merge tag 'perf-tools-for-v6.7-1-2023-11-01' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools updates from Namhyung Kim:
 "Build:

   - Compile BPF programs by default if clang (>= 12.0.1) is available
     to enable more features like kernel lock contention, off-cpu
     profiling, kwork, sample filtering and so on.

     This can be disabled by passing BUILD_BPF_SKEL=0 to make.

   - Produce better error messages for bison on debug build (make
     DEBUG=1) by defining YYDEBUG symbol internally.

  perf record:

   - Track sideband events (like FORK/MMAP) from all CPUs even if perf
     record targets a subset of CPUs only (using -C option). Otherwise
     it may lose some information happened on a CPU out of the target
     list.

   - Fix checking raw sched_switch tracepoint argument using system BTF.
     This affects off-cpu profiling which attaches a BPF program to the
     raw tracepoint.

  perf lock contention:

   - Add --lock-cgroup option to see contention by cgroups. This should
     be used with BPF only (using -b option).

       $ sudo perf lock con -ab --lock-cgroup -- sleep 1
        contended   total wait     max wait     avg wait   cgroup

              835     14.06 ms     41.19 us     16.83 us   /system.slice/led.service
               25    122.38 us     13.77 us      4.89 us   /
               44     23.73 us      3.87 us       539 ns   /user.slice/user-657345.slice/session-c4.scope
                1       491 ns       491 ns       491 ns   /system.slice/connectd.service

   - Add -G/--cgroup-filter option to see contention only for given
     cgroups.

     This can be useful when you identified a cgroup in the above
     command and want to investigate more on it. It also works with
     other output options like -t/--threads and -l/--lock-addr.

       $ sudo perf lock con -ab -G /user.slice/user-657345.slice/session-c4.scope -- sleep 1
        contended   total wait     max wait     avg wait         type   caller

   - Use per-cpu array for better spinlock tracking. This is to improve
     performance of the BPF program and to avoid nested contention on a
     lock in the BPF hash map.

   - Update callstack check for PowerPC. To find a representative caller
     of a lock, it needs to look up the call stacks. It ends the lookup
     when it sees 0 in the call stack buffer. However, PowerPC call
     stacks can have 0 values in the beginning so skip them when it
     expects valid call stacks after.

  perf kwork:

   - Support 'sched' class (for -k option) so that it can see task
     scheduling event (using sched_switch tracepoint) as well as irq and
     workqueue items.

   - Add perf kwork top subcommand to show more accurate cpu utilization
     with sched class above. It works both with a recorded data (using
     perf kwork record command) and BPF (using -b option). Unlike perf
     top command, it does not support interactive mode (yet).

       $ sudo perf kwork top -b -k sched

       Starting trace, Hit <Ctrl+C> to stop and report

  perf bench:

   - Add -G/--cgroups option to perf bench sched pipe. The pipe bench is
     good to measure context switch overhead. With this option, it puts
     the reader and writer tasks in separate cgroups to enforce context
     switch between two different cgroups.

     Also it needs to set CPU affinity of the tasks in a CPU to
     accurately measure the impact of cgroup context switches.

       $ sudo perf stat -e context-switches,cgroup-switches -- \
       > taskset -c 0 perf bench sched pipe -l 100000
       # Running 'sched/pipe' benchmark:
       # Executed 100000 pipe operations between two processes

            Total time: 0.307 [sec]

              3.078180 usecs/op
                324867 ops/sec

        Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000':

                  200,026      context-switches
                       63      cgroup-switches

              0.321637922 seconds time elapsed

     You can see small number of cgroup-switches because both write and
     read tasks are in the same cgroup.

       $ sudo mkdir /sys/fs/cgroup/{AAA,BBB}

       $ sudo perf stat -e context-switches,cgroup-switches -- \
       > taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB
       # Running 'sched/pipe' benchmark:
       # Executed 100000 pipe operations between two processes

            Total time: 0.351 [sec]

              3.512990 usecs/op
                284657 ops/sec

        Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB':

                  200,020      context-switches
                  200,019      cgroup-switches

              0.365034567 seconds time elapsed

     Now context-switches and cgroup-switches are almost same. And you
     can see the pipe operation took little more.

   - Kill child processes when perf bench sched messaging exited
     abnormally. Otherwise it'd leave the child doing unnecessary work.

  perf test:

   - Fix various shellcheck issues on the tests written in shell script.

   - Skip tests when condition is not satisfied:
      - object code reading test for non-text section addresses.
      - CoreSight test if cs_etm// event is not available.
      - lock contention test if not enough CPUs.

  Event parsing:

   - Make PMU alias name loading lazy to reduce the startup time in the
     event parsing code for perf record, stat and others in the general
     case.

   - Lazily compute PMU default config. In the same sense, delay PMU
     initialization until it's really needed to reduce the startup cost.

   - Fix event term values that are raw events. The event specification
     can have several terms including event name. But sometimes it
     clashes with raw event encoding which starts with 'r' and has
     hex-digits.

     For example, an event named 'read' should be processed as a normal
     event but it was mis-treated as a raw encoding and caused a
     failure.

       $ perf stat -e 'uncore_imc_free_running/event=read/' -a sleep 1
       event syntax error: '..nning/event=read/'
                                         \___ parser error
       Run 'perf list' for a list of valid events

        Usage: perf stat [<options>] [<command>]

           -e, --event <event> event selector. use 'perf list' to list available events

  Event metrics:

   - Add "Compat" regex to match event with multiple identifiers.

   - Usual updates for Intel, Power10, Arm telemetry/CMN and AmpereOne.

  Misc:

   - Assorted memory leak fixes and footprint reduction.

   - Add "bpf_skeletons" to perf version --build-options so that users
     can check whether their perf tools have BPF support easily.

   - Fix unaligned access in Intel-PT packet decoder found by
     undefined-behavior sanitizer.

   - Avoid frequency mode for the dummy event. Surprisingly it'd impact
     kernel timer tick handler performance by force iterating all PMU
     events.

   - Update bash shell completion for events and metrics"
