b3f4b679ff leds: flash: leds-qcom-flash: Fix an unsigned comparison which can never be negative
The variable 'count' is defined as unsigned type, so the following if
statement is invalid, we can modify the type of count to int.

if (count <= 0) {
	dev_err(dev, "No led-sources specified\n");
	return -ENODEV;
}

./drivers/leds/flash/leds-qcom-flash.c:546:5-10: WARNING: Unsigned expression compared with zero: count <= 0.

de416a9f91 leds: cht-wcove: Fix an unsigned comparison which can never be negative
The return value from the call to cht_wc_leds_find_freq() is int.
However, the return value is being assigned to an unsigned
int variable 'ctrl', so making it an int.

Eliminate the following warning:
drivers/leds/leds-cht-wcove.c:236 cht_wc_leds_set_effect() warn: unsigned 'ctrl' is never less than zero.

82f80ef5f3 leds: Clear LED_INIT_DEFAULT_TRIGGER when clearing current trigger
Not all triggers use LED_INIT_DEFAULT_TRIGGER, which means that it
will not get cleared when the default trigger is a trigger which
does not use it such as "default-on".

If the default trigger then later gets replaced by a trigger which
does check LED_INIT_DEFAULT_TRIGGER, such as "timer" then that trigger
will behave as if it is the default trigger which it should not do.

To fix this clear the LED_INIT_DEFAULT_TRIGGER flag when clearing
the current trigger, so that it will not be set for any subsequently
set (non default) triggers.

22720a87d0 leds: Fix oops about sleeping in led_trigger_blink()
led_trigger_blink() calls led_blink_set() from a RCU read-side critical
section so led_blink_set() must not sleep. Note sleeping was not allowed
before the switch to RCU either because a spinlock was held before.

led_blink_set() does not sleep when sw-blinking is used, but
many LED controller drivers with hw blink support have a blink_set
function which may sleep, leading to an oops like this one:

Add a new led_blink_set_nosleep() function which defers the actual
led_blink_set() call to a workqueue when necessary to fix this.

This also fixes an existing race where a pending led_set_brightness() has
been deferred to set_brightness_work and might then race with a later
led_cdev->blink_set() call. Note this race is only an issue with triggers
mixing led_trigger_event() and led_trigger_blink() calls, sysfs API
calls and led_trigger_blink_oneshot() are not affected.

Note rather then adding a separate blink_set_blocking callback this uses
the presence of the already existing brightness_set_blocking callback to
detect if the blinking call should be deferred to set_brightness_work.

fa15d8c692 leds: Fix set_brightness_delayed() race
When a trigger wants to switch from blinking to LED on it needs to call:
	led_set_brightness(LED_OFF);
	led_set_brightness(LED_FULL);

To first call disables blinking and the second then turns the LED on
(the power-supply charging-blink-full-solid triggers do this).

These calls happen immediately after each other, so it is possible
that set_brightness_delayed() from the first call has not run yet
when the led_set_brightness(LED_FULL) call finishes.

If this race hits then this is causing problems for both
sw- and hw-blinking:

For sw-blinking set_brightness_delayed() clears delayed_set_value
when LED_BLINK_DISABLE is set causing the led_set_brightness(LED_FULL)
call effects to get lost when hitting the race, resulting in the LED
turning off instead of on.

For hw-blinking if the race hits delayed_set_value has been
set to LED_FULL by the time set_brightness_delayed() runs.
So led_cdev->brightness_set_blocking() is never called with
LED_OFF as argument and the hw-blinking is never disabled leaving
the LED blinking instead of on.

Fix both issues by adding LED_SET_BRIGHTNESS and LED_SET_BRIGHTNESS_OFF
work_flags making this 2 separate actions to be run by
set_brightness_delayed().

e298d8a38b leds: Change led_trigger_blink[_oneshot]() delay parameters to pass-by-value
led_blink_set[_oneshot]()'s delay_on and delay_off function parameters
are pass by reference, so that hw-blink implementations can report
back the actual achieved delays when the values have been rounded
to something the hw supports.

This is really only interesting for the sysfs API / the timer trigger.
Other triggers don't really care about this and none of the callers of
led_trigger_blink[_oneshot]() do anything with the returned delay values.

Change the led_trigger_blink[_oneshot]() delay parameters to pass-by-value,
there are 2 reasons for this:

1. led_cdev->blink_set() may sleep, while led_trigger_blink() may not.
So on hw where led_cdev->blink_set() sleeps the call needs to be deferred
to a workqueue, in which case the actual achieved delays are unknown
(this is a preparation patch for the deferring).

2. Since the callers don't care about the actual achieved delays, allowing
callers to directly pass a value leads to simpler code for most callers.

ea0c0a8536 leds: cht-wcove: Use breathing when LED_INIT_DEFAULT_TRIGGER is set
The desired default behavior of LED1 / the charge LED is breathing
while charging and on/solid when full. Since triggers cannot select
breathing, blink_set() gets called when charging. Use breathing
when the default "charging-blink-full-solid" trigger is used to
achieve the desired default behavior.

5b916aa755 leds: cht-wcove: Add support for breathing mode use hw_pattern sysfs API
The hw-blinking of the LED controller in the Whiskey Cove PMIC can also
be used for a hw-breathing effect.

As discussed during review of v2 of the submission of the new
leds-cht-wcove driver, the LED subsystem already supports breathing mode
on several other LED controllers using the hw_pattern interface.

Implement a pattern_set callback to implement breathing mode modelled
after the breathing mode supported by the SC27xx breathing light and
Crane EL15203000 LED drivers. The Whiskey Cove PMIC's breathing mode
is closer to the EL15203000 one then to the SC27xx one since it does
not support staying high / low for a specific time, it only supports
rise and fall times.

As such the supported hw_pattern and the documentation for this is almost
a 1:1 copy of the pattern/docs for the EL15203000 breathing mode.

9697e2f01f leds: cht-wcove: Add suspend/resume handling
When LED1 is showing the tablet is charging and then the device gets
suspended followed by unplugging the charger, then it will incorrectly
still show it is charging.

To avoid this turn both LEDs off on suspend, just like the PMIC always
turns them off when the tablet is powered off (even if the tablet is
charging). If hw-control is supported for LED1, then restore the
initial hw-control settings to let the hw control LED1 while suspended.

To restore the state the LEDs had before suspending, save it before
turning the LEDs off and restore it on resume.

047da762b9 leds: Add Intel Cherry Trail Whiskey Cove PMIC LED driver
Add support for LEDs connected to the Intel Cherry Trail Whiskey Cove
PMIC. Charger and general-purpose LEDs are supported. Hardware blinking
is implemented, breathing is not.

This driver was tested with Lenovo Yoga Book notebook.

Changes by Hans de Goede (in response to review of v2):
- Since the PMIC is connected to the battery any changes we make to
  the LED settings are permanent, even surviving reboot / poweroff.
  Save LED1 register settings on probe() and if auto-/hw-control was
  enabled on probe() restore the settings on remove() and shutdown().
- Delay switching LED1 to software control mode to first brightness write.
- Use dynamically allocated drvdata instead of a global drvdata variable.
- Ensure the LED is on when activating blinking.
- Fix CHT_WC_LED_EFF_BREATHING val ((3 << 1) rather then BIT(3)).

Commit e91a4d5deb ("dt-bindings: leds: Document commonly used

'^cpu[0-9]*$' already exists.

This causes linux,default-trigger = "cpu" to have more than one match

Drop the explicit match against cpu since the pattern match already
covers the same.

The LP55xx range of devices have an internal charge pump which
can (automatically) increase the output voltage towards the
LED's, boosting the output voltage to 4.5V.

Implement this option from the devicetree. When the setting
is not present it will operate in automatic mode as before.

Tested on LP55231. Datasheet analysis shows that LP5521, LP5523

d1b9e1391a leds: trigger: netdev: Use mutex instead of spinlocks
Some LEDs may require to sleep while doing some operation like setting
brightness and other cleanup.

For this reason, using a spinlock will cause a sleep under spinlock
warning.

It should be safe to convert this to a sleepable lock since:
- sysfs read/write can sleep
- netdev_trig_work is a work queue and can sleep
- netdev _trig_notify can sleep

The spinlock was used when brightness didn't support sleeping, but this
changed and now it supported with brightness_set_blocking().

Convert to mutex lock to permit sleeping using brightness_set_blocking().

to set a blink mode as it's done by NETDEV_LED_LINK, NETDEV_LED_TX and
NETDEV_LED_RX. It's also wrong to put this state in the same bitmap of the

Merge tag 'perf-tools-for-v6.4-3-2023-05-06' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tool updates from Arnaldo Carvalho de Melo:
 "Third version of perf tool updates, with the build problems with with
  using a 'vmlinux.h' generated from the main build fixed, and the bpf
  skeleton build disabled by default.

  Build:

   - Require libtraceevent to build, one can disable it using
     NO_LIBTRACEEVENT=1.

     It is required for tools like 'perf sched', 'perf kvm', 'perf
     trace', etc.

     libtraceevent is available in most distros so installing
     'libtraceevent-devel' should be a one-time event to continue
     building perf as usual.

     Using NO_LIBTRACEEVENT=1 produces tooling that is functional and
     sufficient for lots of users not interested in those libtraceevent
     dependent features.

   - Allow Python support in 'perf script' when libtraceevent isn't
     linked, as not all features requires it, for instance Intel PT does
     not use tracepoints.

   - Error if the python interpreter needed for jevents to work isn't
     available and NO_JEVENTS=1 isn't set, preventing a build without
     support for JSON vendor events, which is a rare but possible
     condition. The two check error messages:

        $(error ERROR: No python interpreter needed for jevents generation. Install python or build with NO_JEVENTS=1.)
        $(error ERROR: Python interpreter needed for jevents generation too old (older than 3.6). Install a newer python or build with NO_JEVENTS=1.)

   - Make libbpf 1.0 the minimum required when building with out of
     tree, distro provided libbpf.

   - Use libsdtc++'s and LLVM's libcxx's __cxa_demangle, a portable C++
     demangler, add 'perf test' entry for it.

   - Make binutils libraries opt in, as distros disable building with it
     due to licensing, they were used for C++ demangling, for instance.

   - Switch libpfm4 to opt-out rather than opt-in, if libpfm-devel (or
     equivalent) isn't installed, we'll just have a build warning:

       Makefile.config:1144: libpfm4 not found, disables libpfm4 support. Please install libpfm4-dev

   - Add a feature test for scandirat(), that is not implemented so far
     in musl and uclibc, disabling features that need it, such as
     scanning for tracepoints in /sys/kernel/tracing/events.

  perf BPF filters:

   - New feature where BPF can be used to filter samples, for instance:

      $ sudo ./perf record -e cycles --filter 'period > 1000' true
      $ sudo ./perf script
           perf-exec 2273949 546850.708501:       5029 cycles:  ffffffff826f9e25 finish_wait+0x5 ([kernel.kallsyms])

   - In addition to 'period' (PERF_SAMPLE_PERIOD), the other
     PERF_SAMPLE_ can be used for filtering, and also some other sample
     accessible values, from tools/perf/Documentation/perf-record.txt:

        Essentially the BPF filter expression is:

        <term> <operator> <value> (("," | "||") <term> <operator> <value>)*

     The <term> can be one of:
        ip, id, tid, pid, cpu, time, addr, period, txn, weight, phys_addr,
        code_pgsz, data_pgsz, weight1, weight2, weight3, ins_lat, retire_lat,
        p_stage_cyc, mem_op, mem_lvl, mem_snoop, mem_remote, mem_lock,
        mem_dtlb, mem_blk, mem_hops

     The <operator> can be one of:
        ==, !=, >, >=, <, <=, &

     The <value> can be one of:
        <number> (for any term)
        na, load, store, pfetch, exec (for mem_op)
        l1, l2, l3, l4, cxl, io, any_cache, lfb, ram, pmem (for mem_lvl)
        na, none, hit, miss, hitm, fwd, peer (for mem_snoop)
        remote (for mem_remote)
        na, locked (for mem_locked)
        na, l1_hit, l1_miss, l2_hit, l2_miss, any_hit, any_miss, walk, fault (for mem_dtlb)
        na, by_data, by_addr (for mem_blk)
        hops0, hops1, hops2, hops3 (for mem_hops)

  perf lock contention:

   - Show lock type with address.

   - Track and show mmap_lock, siglock and per-cpu rq_lock with address.
     This is done for mmap_lock by following the current->mm pointer:

      $ sudo ./perf lock con -abl -- sleep 10

   - Update default map size to 16384.

   - Allocate single letter option -M for --map-nr-entries, as it is
     proving being frequently used.

   - Fix struct rq lock access for older kernels with BPF's CO-RE
     (Compile once, run everywhere).

   - Fix problems found with MSAn.

  perf report/top:

   - Add inline information when using --call-graph=fp or lbr, as was
     already done to the --call-graph=dwarf callchain mode.

   - Improve the 'srcfile' sort key performance by really using an
     optimization introduced in 6.2 for the 'srcline' sort key that
     avoids calling addr2line for comparision with each sample.

  perf sched:

   - Make 'perf sched latency/map/replay' to use "sched:sched_waking"
     instead of "sched:sched_waking", consistent with 'perf record'
     since d566a9c2d4 ("perf sched: Prefer sched_waking event when it
     exists").

  perf ftrace:

   - Make system wide the default target for latency subcommand, run the
     following command then generate some network traffic and press
     control+C:

       # perf ftrace latency -T __kfree_skb
     ^C

       #

  perf top:

   - Add --branch-history (LBR: Last Branch Record) option, just like
     already available for 'perf record'.

   - Fix segfault in thread__comm_len() where thread->comm was being
     used outside thread->comm_lock.

  perf annotate:

   - Allow configuring objdump and addr2line in ~/.perfconfig., so that
     you can use alternative binaries, such as llvm's.

  perf kvm:

   - Add TUI mode for 'perf kvm stat report'.

  Reference counting:

   - Add reference count checking infrastructure to check for use after
     free, done to the 'cpumap', 'namespaces', 'maps' and 'map' structs,
     more to come.

     To build with it use -DREFCNT_CHECKING=1 in the make command line
     to build tools/perf. Documented at:

       https://perf.wiki.kernel.org/index.php/Reference_Count_Checking

   - The above caught, for instance, fix, present in this series:

        - Fix maps use after put in 'perf test "Share thread maps"':

          'maps' is copied from leader, but the leader is put on line 79
          and then 'maps' is used to read the reference count below - so
          a use after put, with the put of maps happening within
          thread__put.

     Fixed by reversing the order of puts so that the leader is put
     last.

   - Also several fixes were made to places where reference counts were
     not being held.

   - Make this one of the tests in 'make -C tools/perf build-test' to
     regularly build test it and to make sure no direct access to the
     reference counted structs are made, doing that via accessors to
     check the validity of the struct pointer.

  ARM64:

   - Fix 'perf report' segfault when filtering coresight traces by
     sparse lists of CPUs.

   - Add support for 'simd' as a sort field for 'perf report', to show
     ARM's NEON SIMD's predicate flags: "partial" and "empty".

  arm64 vendor events:

   - Add N1 metrics.

  Intel vendor events:

   - Add graniterapids, grandridge and sierraforrest events.

   - Refresh events for: alderlake, aldernaken, broadwell, broadwellde,
     broadwellx, cascadelakx, haswell, haswellx, icelake, icelakex,
     jaketown, meteorlake, knightslanding, sandybridge, sapphirerapids,
     silvermont, skylake, tigerlake and westmereep-dp

   - Refresh metrics for alderlake-n, broadwell, broadwellde,
     broadwellx, haswell, haswellx, icelakex, ivybridge, ivytown and
     skylakex.

  perf stat:

   - Implement --topdown using JSON metrics.

   - Add TopdownL1 JSON metric as a default if present, but disable it
     for now for some Intel hybrid architectures, a series of patches
     addressing this is being reviewed and will be submitted for v6.5.

   - Use metrics for --smi-cost.

   - Update topdown documentation.

  Vendor events (JSON) infrastructure:

   - Add support for computing and printing metric threshold values. For
     instance, here is one found in thesapphirerapids json file:

       {
           "BriefDescription": "Percentage of cycles spent in System Management Interrupts.",
           "MetricExpr": "((msr@aperf@ - cycles) / msr@aperf@ if msr@smi@ > 0 else 0)",
           "MetricGroup": "smi",
           "MetricName": "smi_cycles",
           "MetricThreshold": "smi_cycles > 0.1",
           "ScaleUnit": "100%"
       },

   - Test parsing metric thresholds with the fake PMU in 'perf test
     pmu-events'.

   - Support for printing metric thresholds in 'perf list'.

   - Add --metric-no-threshold option to 'perf stat'.

   - Add rand (reverse and) and has_pmem (optane memory) support to
     metrics.

   - Sort list of input files to avoid depending on the order from
     readdir() helping in obtaining reproducible builds.

  S/390:

   - Add common metrics: - CPI (cycles per instruction), prbstate (ratio
     of instructions executed in problem state compared to total number
     of instructions), l1mp (Level one instruction and data cache misses
     per 100 instructions).

   - Add cache metrics for z13, z14, z15 and z16.

   - Add metric for TLB and cache.

  ARM:

   - Add raw decoding for SPE (Statistical Profiling Extension) v1.3 MTE
     (Memory Tagging Extension) and MOPS (Memory Operations) load/store.

  Intel PT hardware tracing:

   - Add event type names UINTR (User interrupt delivered) and UIRET
     (Exiting from user interrupt routine), documented in table 32-50
     "CFE Packet Type and Vector Fields Details" in the Intel Processor
     Trace chapter of The Intel SDM Volume 3 version 078.

   - Add support for new branch instructions ERETS and ERETU.

   - Fix CYC timestamps after standalone CBR

  ARM CoreSight hardware tracing:

   - Allow user to override timestamp and contextid settings.

   - Fix segfault in dso lookup.

   - Fix timeless decode mode detection.

   - Add separate decode paths for timeless and per-thread modes.

  auxtrace:

   - Fix address filter entire kernel size.

  Miscellaneous:

   - Fix use-after-free and unaligned bugs in the PLT handling routines.

   - Use zfree() to reduce chances of use after free.

   - Add missing 0x prefix for addresses printed in hexadecimal in 'perf
     probe'.

   - Suppress massive unsupported target platform errors in the unwind
     code.

   - Fix return incorrect build_id size in elf_read_build_id().

   - Fix 'perf scripts intel-pt-events.py' IPC output for Python 2 .

   - Add missing new parameter in kfree_skb tracepoint to the python
     scripts using it.

   - Add 'perf bench syscall fork' benchmark.

   - Add support for printing PERF_MEM_LVLNUM_UNC (Uncached access) in
     'perf mem'.

   - Fix wrong size expectation for perf test 'Setup struct
     perf_event_attr' caused by the patch adding
     perf_event_attr::config3.

   - Fix some spelling mistakes"

17784de648 A single fix for debugobjects:
The recent fix to ensure atomicity of lookup and allocation inadvertently
   broke the pool refill mechanism, so that debugobject OOMs now in certain
   situations. The reason is that the functions which got updated no longer
   invoke debug_objecs_init(), which is now the only place to care about
   refilling the tracking object pool.
 
   Restore the original behaviour by adding explicit refill opportunities to
   those places.

d6b8a8c49a A couple more patches that would be good to get into -rc1.
- Revert an i.MX patch that's causing video failures because division
    math goes sideways
  - Fix a clang + W=1 build isue where FIELD_PREP() is taking a 32-bit
    variable instead of the usual u64 type
  - Fix a Kconfig bug in the StarFive JH7110 clk config that selects a
    reset controller when it can't be selected

Merge tag 'for-6.4/io_uring-2023-05-07' of git://git.kernel.dk/linux

Pull more io_uring updates from Jens Axboe:
 "Nothing major in here, just two different parts:

   - A small series from Breno that enables passing the full SQE down
     for ->uring_cmd().

     This is a prerequisite for enabling full network socket operations.
     Queued up a bit late because of some stylistic concerns that got
     resolved, would be nice to have this in 6.4-rc1 so the dependent
     work will be easier to handle for 6.5.

   - Fix for the huge page coalescing, which was a regression introduced
     in the 6.3 kernel release (Tobias)"

* tag 'for-6.4/io_uring-2023-05-07' of git://git.kernel.dk/linux:
  io_uring: Remove unnecessary BUILD_BUG_ON
  io_uring: Pass whole sqe to commands

9a2d5178b9 Revert "perf build: Make BUILD_BPF_SKEL default, rename to NO_BPF_SKEL"
This reverts commit a980755beb.

We need to better polish building with BPF skels, so revert back to
making it an experimental feature that has to be explicitely enabled
using BUILD_BPF_SKEL=1.
