While debugging a issue, we needed to stress test the percpu alloc/free
path. Hence added some tests in lib/percpu_test to stress test
percpu subsystem for allocation with different sizes.

This patch keeps the default behavior of insmod module same for default
test. But when given insmod with different option, it can run a
percpu_stressd daemon (percpu_test_num=2) which does a stress test
evey 10secs unless the module is unloaded.

We found this to be helpful in our testing, since with this we could
easily excercise percpu allo/free path. Hence cleaned this up for
inclusion in percpu_test module.

Make schedule_on_each_cpu as EXPORT_SYMBOL.

Prior to "percpu: implement partial chunk depopulation",
pcpu_depopulate_chunk() was called only on the destruction path. This
meant the virtual address range was on its way back to vmalloc which
will handle flushing the tlbs for us.

However, with pcpu_reclaim_populated(), we are now calling
pcpu_depopulate_chunk() during the active lifecycle of a chunk.
Therefore, we need to flush the tlb as well otherwise we can end up
accessing the wrong page through an invalid tlb mapping as reported in
[1].

Pull tracing updates from Steven Rostedt:

 - Added option for per CPU threads to the hwlat tracer

 - Have hwlat tracer handle hotplug CPUs

 - New tracer: osnoise, that detects latency caused by interrupts,
   softirqs and scheduling of other tasks.

 - Added timerlat tracer that creates a thread and measures in detail
   what sources of latency it has for wake ups.

 - Removed the "success" field of the sched_wakeup trace event. This has
   been hardcoded as "1" since 2015, no tooling should be looking at it
   now. If one exists, we can revert this commit, fix that tool and try
   to remove it again in the future.

 - tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids.

 - New boot command line option "tp_printk_stop", as tp_printk causes
   trace events to write to console. When user space starts, this can
   easily live lock the system. Having a boot option to stop just after
   boot up is useful to prevent that from happening.

 - Have ftrace_dump_on_oops boot command line option take numbers that
   match the numbers shown in /proc/sys/kernel/ftrace_dump_on_oops.

 - Bootconfig clean ups, fixes and enhancements.

 - New ktest script that tests bootconfig options.

 - Add tracepoint_probe_register_may_exist() to register a tracepoint
   without triggering a WARN*() if it already exists. BPF has a path
   from user space that can do this. All other paths are considered a
   bug.

This reverts commit 9ce650a.

This commit causes watchdog lockups on my machine, and while I have no
idea what the cause is, it bisected right to this commit, and reverting
the change promptly fixes it.

At least occasionally one of the watchdog call traces was

  Call Trace:
    _raw_spin_lock_irqsave+0x35/0x40
    snd_pcm_period_elapsed+0x1b/0xa0 [snd_pcm]
    snd_usb_endpoint_start+0x1a0/0x3c0 [snd_usb_audio]
    start_endpoints+0x23/0x90 [snd_usb_audio]
    snd_usb_substream_playback_trigger+0x7b/0x1a0 [snd_usb_audio]
    snd_pcm_common_ioctl+0x1c44/0x2360 [snd_pcm]
    snd_pcm_ioctl+0x2e/0x40 [snd_pcm]
    __se_sys_ioctl+0x72/0xc0
    do_syscall_64+0x4c/0xa0
    entry_SYSCALL_64_after_hwframe+0x44/0xae

so presumably it's a locking error on that substream spinlock that
snd_pcm_period_elapsed() takes.  But at this point I just want to have a
working system so that I can continue the merge window work tomorrow.

Pull xfs updates from Darrick Wong:
 "Most of the work this cycle has been on refactoring various parts of
  the codebase. The biggest non-cleanup changes are (1) reducing the
  number of cache flushes sent when writing the log; (2) a substantial
  number of log recovery fixes; and (3) I started accepting pull
  requests from contributors if the commits in their branches match
  what's been sent to the list.

  For a week or so I /had/ staged a major cleanup of the logging code
  from Dave Chinner, but it exposed so many lurking bugs in other parts
  of the logging and log recovery code that I decided to defer that
  patchset until we can address those latent bugs.

  Larger cleanups this time include walking the incore inode cache (me)
  and rework of the extended attribute code (Allison) to prepare it for
  adding logged xattr updates (and directory tree parent pointers) in
  future releases.

  Summary:

   - Refactor the buffer cache to use bulk page allocation

   - Convert agnumber-based AG iteration to walk per-AG structures

   - Clean up some unit conversions and other code warts

   - Reduce spinlock contention in the directio fastpath

   - Collapse all the inode cache walks into a single function

   - Remove indirect function calls from the inode cache walk code

   - Dramatically reduce the number of cache flushes sent when writing
     log buffers

   - Preserve inode sickness reports for longer

   - Rename xfs_eofblocks since it controls inode cache walks

   - Refactor the extended attribute code to prepare it for the addition
     of log intent items to make xattrs fully transactional

   - A few fixes to earlier large patchsets

   - Log recovery fixes so that we don't accidentally mark the log clean
     when log intent recovery fails

   - Fix some latent SOB errors

   - Clean up shutdown messages that get logged to dmesg

   - Fix a regression in the online shrink code

   - Fix a UAF in the buffer logging code if the fs goes offline

   - Fix uninitialized error variables

   - Fix a UAF in the CIL when commited log item callbacks race with a
     shutdown

   - Fix a bug where the CIL could hang trying to push part of the log
     ring buffer that hasn't been filled yet"

…m/linux/kernel/git/arnd/asm-generic

Pull asm/unaligned.h unification from Arnd Bergmann:
 "Unify asm/unaligned.h around struct helper

  The get_unaligned()/put_unaligned() helpers are traditionally
  architecture specific, with the two main variants being the
  "access-ok.h" version that assumes unaligned pointer accesses always
  work on a particular architecture, and the "le-struct.h" version that
  casts the data to a byte aligned type before dereferencing, for
  architectures that cannot always do unaligned accesses in hardware.

  Based on the discussion linked below, it appears that the access-ok
  version is not realiable on any architecture, but the struct version
  probably has no downsides. This series changes the code to use the
  same implementation on all architectures, addressing the few
  exceptions separately"

 "This is the bulk of pin control changes for the v5.14 kernel. Not so
  much going on. No core changes, just drivers.

  The most interesting would be that MIPS Ralink is migrating to pin
  control and we have some bindings but not yet code for the Apple M1
  pin controller.

  New drivers:

   - Last merge window we created a driver for the Ralink RT2880. We are
     now moving the Ralink SoC pin control drivers out of the MIPS
     architecture code and into the pin control subsystem. This concerns
     RT288X, MT7620, RT305X, RT3883 and MT7621.

   - Qualcomm SM6125 SoC pin control driver.

   - Qualcomm spmi-gpio support for PM7325.

   - Qualcomm spmi-mpp also handles PMI8994 (just a compatible string)

   - Mediatek MT8365 SoC pin controller.

   - New device HID for the AMD GPIO controller.

  Improvements:

   - Pin bias config support for a slew of Renesas pin controllers.

   - Incremental improvements and non-urgent bug fixes to the Renesas
     SoC drivers.

   - Implement irq_set_wake on the AMD pin controller so we can wake up
     from external pin events.

  Misc:

   - Devicetree bindings for the Apple M1 pin controller, we will
     probably see a proper driver for this soon as well"

…l/git/clk/linux

Pull clk updates from Stephen Boyd:
 "This round has a diffstat dominated by Qualcomm clk drivers. Honestly
  though that's just a bunch of data so the diffstat reflects that.
  Looking beyond that there's just a bunch of updates all around in
  various clk drivers. Renesas and NXP (for i.MX) are two SoC vendors
  that have a lot of patches in here.

  Overall the driver changes look to be mostly enabling more clks and
  non-critical fixes that we could hold until the next merge window.

  I'm especially excited about the series from Arnd that graduates
  clkdev to be the only implementation of clk_get() and clk_put().
  That's a good step in the right direction to migreate eveerything over
  to the common clk framework. Now we don't have to worry about clkdev
  specific details, they're just part of the clk API now.

  Core:
   - clkdev is now the only option, i.e. clk_get()/clk_put() is
     implemented in only one place in the kernel instead of in
     drivers/clk/clkdev.c and in architectures that want their own
     implementation

  New Drivers:
   - Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant
     Clock Jitter Cleaner With Dual Loop PLLs
   - Qualcomm MDM9607 GCC
   - Qualcomm SC8180X display clks
   - Qualcomm SM6125 GCC
   - Qualcomm SM8250 CAMCC (camera)
   - Renesas RZ/G2L SoC
   - Hisilicon hi3559A SoC

  Updates:
   - Stop using clock-output-names in ST clk drivers (yay!)
   - Support secure mode of STM32MP1 SoCs
   - Improve clock support for Actions S500 SoC
   - duty cycle setting support on qcom clks
   - Add TI am33xx spread spectrum clock support
   - Use determine_rate() for the Amlogic pll ops instead of

ASan reports a memory leak caused by evlist not being deleted on exit in
perf-report, perf-script and perf-data.
The problem is caused by evlist->session not being deleted, which is
allocated in perf_session__read_header, called in perf_session__new if
perf_data is in read mode.
In case of write mode, the session->evlist is filled by the caller.
This patch solves the problem by calling evlist__delete in
perf_session__delete if perf_data is in read mode.

Changes in v2:
 - call evlist__delete from within perf_session__delete

v1: https://lore.kernel.org/lkml/20210621234317.235545-1-rickyman7@gmail.com/

ASan report follows:

In perf annotate, when 's' is pressed on a line containing source code,
it shows the message "Only available for assembly lines".

This patch gets rid of the error, moving the cursr to the next available
asm line (or the closest previous one if no asm line is found moving
forwards), before hiding source code lines.

Changes in v2:
 - handle case of no asm line found in
   annotate_browser__find_next_asm_line by returning NULL and
   handling error in caller.
