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. - Small clean ups and fixes * tag 'trace-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (49 commits) tracing: Resize tgid_map to pid_max, not PID_MAX_DEFAULT tracing: Simplify & fix saved_tgids logic treewide: Add missing semicolons to __assign_str uses tracing: Change variable type as bool for clean-up trace/timerlat: Fix indentation on timerlat_main() trace/osnoise: Make 'noise' variable s64 in run_osnoise() tracepoint: Add tracepoint_probe_register_may_exist() for BPF tracing tracing: Fix spelling in osnoise tracer "interferences" -> "interference" Documentation: Fix a typo on trace/osnoise-tracer trace/osnoise: Fix return value on osnoise_init_hotplug_support trace/osnoise: Make interval u64 on osnoise_main trace/osnoise: Fix 'no previous prototype' warnings tracing: Have osnoise_main() add a quiescent state for task rcu seq_buf: Make trace_seq_putmem_hex() support data longer than 8 seq_buf: Fix overflow in seq_buf_putmem_hex() trace/osnoise: Support hotplug operations trace/hwlat: Support hotplug operations trace/hwlat: Protect kdata->kthread with get/put_online_cpus trace: Add timerlat tracer trace: Add osnoise tracer ...

This reverts commit 9ce650a7. 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" * tag 'xfs-5.14-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (102 commits) xfs: don't wait on future iclogs when pushing the CIL xfs: Fix a CIL UAF by getting get rid of the iclog callback lock xfs: remove callback dequeue loop from xlog_state_do_iclog_callbacks xfs: don't nest icloglock inside ic_callback_lock xfs: Initialize error in xfs_attr_remove_iter xfs: fix endianness issue in xfs_ag_shrink_space xfs: remove dead stale buf unpin handling code xfs: hold buffer across unpin and potential shutdown processing xfs: force the log offline when log intent item recovery fails xfs: fix log intent recovery ENOSPC shutdowns when inactivating inodes xfs: shorten the shutdown messages to a single line xfs: print name of function causing fs shutdown instead of hex pointer xfs: fix type mismatches in the inode reclaim functions xfs: separate primary inode selection criteria in xfs_iget_cache_hit xfs: refactor the inode recycling code xfs: add iclog state trace events xfs: xfs_log_force_lsn isn't passed a LSN xfs: Fix CIL throttle hang when CIL space used going backwards xfs: journal IO cache flush reductions xfs: remove need_start_rec parameter from xlog_write() ...

Merge tag 'asm-generic-unaligned-5.14' of git://git.kernel.org/pub/scm/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" Link: https://lore.kernel.org/lkml/75d07691-1e4f-741f-9852-38c0b4f520bc@synopsys.com/ Link: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100363 Link: https://lore.kernel.org/lkml/20210507220813.365382-14-arnd@kernel.org/ Link: git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic.git unaligned-rework-v2 Link: https://lore.kernel.org/lkml/CAHk-=whGObOKruA_bU3aPGZfoDqZM1_9wBkwREp0H0FgR-90uQ@mail.gmail.com/ * tag 'asm-generic-unaligned-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic: simplify asm/unaligned.h asm-generic: uaccess: 1-byte access is always aligned netpoll: avoid put_unaligned() on single character mwifiex: re-fix for unaligned accesses apparmor: use get_unaligned() only for multi-byte words partitions: msdos: fix one-byte get_unaligned() asm-generic: unaligned always use struct helpers asm-generic: unaligned: remove byteshift helpers powerpc: use linux/unaligned/le_struct.h on LE power7 m68k: select CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS sh: remove unaligned access for sh4a openrisc: always use unaligned-struct header asm-generic: use asm-generic/unaligned.h for most architectures

Pull pin control updates from Linus Walleij: "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.

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.

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: $ ./perf script report

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.

filter_event_early() can be more than 30% faster than filter_event() because it is called before internal filtering. In other respects it is the same as filter_event(), except that it will be passed events that have yet to be filtered out.

In some cases, users want to filter very large amounts of data (e.g. from AUX area tracing like Intel PT) looking for something specific. While scripting such as Python can be used, Python is 10 to 20 times slower than C. So define a C API so that custom filters can be written and loaded.
