printk: Add printk.console_no_auto_verbose boot parameter
console_verbose() increases console loglevel to CONSOLE_LOGLEVEL_MOTORMOUTH, which provides more information to debug a panic/oops. Unfortunately, in Arista we maintain some DUTs (Device Under Test) that are configured to have 9600 baud rate. While verbose console messages have their value to post-analyze crashes, on such setup they: - may prevent panic/oops messages being printed - take too long to flush on console resulting in watchdog reboot In all our setups we use kdump which saves dmesg buffer after panic, so in reality those extra messages on console provide no additional value, but rather add risk of not getting to __crash_kexec(). Provide printk.console_no_auto_verbose boot parameter, which allows to switch off printk being verbose on oops/panic/lockdep.

This was a reasonably active cycle for documentation; this pull includes:
- Some kernel-doc cleanups. That script is still regex onslaught from
hell, but it has gotten a little better.
- Improvements to the checkpatch docs, which are also used by the tool
itself.
- A major update to the pathname lookup documentation.
- Elimination of :doc: markup, since our automarkup magic can create
references from filenames without all the extra noise.
- The flurry of Chinese translation activity continues.
Plus, of course, the usual collection of updates, typo fixes, and warning
fixes.

Pull btrfs updates from David Sterba:
"A normal mix of improvements, core changes and features that user have
been missing or complaining about.
User visible changes:
- new sysfs exports:
- add sysfs knob to limit scrub IO bandwidth per device
- device stats are also available in
/sys/fs/btrfs/FSID/devinfo/DEVID/error_stats
- support cancellable resize and device delete ioctls
- change how the empty value is interpreted when setting a property,
so far we have only 'btrfs.compression' and we need to distinguish
a reset to defaults and setting "do not compress", in general the
empty value will always mean 'reset to defaults' for any other
property, for compression it's either 'no' or 'none' to forbid
compression
Performance improvements:
- no need for full sync when truncation does not touch extents,
reported run time change is -12%
- avoid unnecessary logging of xattrs during fast fsyncs (+17%
throughput, -17% runtime on xattr stress workload)
Core:
- preemptive flushing improvements and fixes
- adjust clamping logic on multi-threaded workloads to avoid
flushing too soon
- take into account global block reserve, may help on almost full
filesystems
- continue flushing when there are enough pending delalloc and
ordered bytes
- simplify logic around conditional transaction commit, a workaround
used in the past for throttling that's been superseded by ticket
reservations that manage the throttling in a better way
- subpage blocksize preparation:
- submit read time repair only for each corrupted sector
- scrub repair now works with sectors and not pages
- free space cache (v1) works with sectors and not pages
- more fine grained bio tracking for extents
- subpage support in page callbacks, extent callbacks, end io
callbacks
- simplify transaction abort logic and always abort and don't check
various potentially unreliable stats tracked by the transaction
- exclusive operations can do more checks when started and allow eg.
cancellation of the same running operation
- ensure relocation never runs while we have send operations running,
e.g. when zoned background auto reclaim starts
Fixes:
- zoned: more sanity checks of write pointer
- improve error handling in delayed inodes
- send:
- fix invalid path for unlink operations after parent
orphanization
- fix crash when memory allocations trigger reclaim
- skip compression of we have only one page (can't make things
better)
- empty value of a property newly means reset to default
Other:
- lots of cleanups, comment updates, yearly typo fixing
- disable build on platforms having page size 256K"

Changes in this cycle were:
- Add the "ratelimit:N" parameter to the split_lock_detect= boot option,
to rate-limit the generation of bus-lock exceptions. This is both
easier on system resources and kinder to offending applications than
the current policy of outright killing them.
- Document the split-lock detection feature and its parameters.

seccomp: Support atomic "addfd + send reply"
Alban Crequy reported a race condition userspace faces when we want to add some fds and make the syscall return them[1] using seccomp notify. The problem is that currently two different ioctl() calls are needed by the process handling the syscalls (agent) for another userspace process (target): SECCOMP_IOCTL_NOTIF_ADDFD to allocate the fd and SECCOMP_IOCTL_NOTIF_SEND to return that value. Therefore, it is possible for the agent to do the first ioctl to add a file descriptor but the target is interrupted (EINTR) before the agent does the second ioctl() call. This patch adds a flag to the ADDFD ioctl() so it adds the fd and returns that value atomically to the target program, as suggested by Kees Cook[2]. This is done by simply allowing seccomp_do_user_notification() to add the fd and return it in this case. Therefore, in this case the target wakes up from the wait in seccomp_do_user_notification() either to interrupt the syscall or to add the fd and return it. This "allocate an fd and return" functionality is useful for syscalls that return a file descriptor only, like connect(2). Other syscalls that return a file descriptor but not as return value (or return more than one fd), like socketpair(), pipe(), recvmsg with SCM_RIGHTs, will not work with this flag. This effectively combines SECCOMP_IOCTL_NOTIF_ADDFD and SECCOMP_IOCTL_NOTIF_SEND into an atomic opteration. The notification's return value, nor error can be set by the user. Upon successful invocation of the SECCOMP_IOCTL_NOTIF_ADDFD ioctl with the SECCOMP_ADDFD_FLAG_SEND flag, the notifying process's errno will be 0, and the return value will be the file descriptor number that was installed.

Updates to the tick/nohz code in this cycle:
- Micro-optimize tick_nohz_full_cpu()
- Optimize idle exit tick restarts to be less eager
- Optimize tick_nohz_dep_set_task() to only wake up
a single CPU. This reduces IPIs and interruptions
on nohz_full CPUs.
- Optimize tick_nohz_dep_set_signal() in a similar
fashion.
- Skip IPIs in tick_nohz_kick_task() when trying
to kick a non-running task.
- Micro-optimize tick_nohz_task_switch() IRQ flags
handling to reduce context switching costs.
- Misc cleanups and fixes

Scheduler udpates for this cycle:
- Changes to core scheduling facilities:
- Add "Core Scheduling" via CONFIG_SCHED_CORE=y, which enables
coordinated scheduling across SMT siblings. This is a much
requested feature for cloud computing platforms, to allow
the flexible utilization of SMT siblings, without exposing
untrusted domains to information leaks & side channels, plus
to ensure more deterministic computing performance on SMT
systems used by heterogenous workloads.
There's new prctls to set core scheduling groups, which
allows more flexible management of workloads that can share
siblings.
- Fix task->state access anti-patterns that may result in missed
wakeups and rename it to ->__state in the process to catch new
abuses.
- Load-balancing changes:
- Tweak newidle_balance for fair-sched, to improve
'memcache'-like workloads.
- "Age" (decay) average idle time, to better track & improve workloads
such as 'tbench'.
- Fix & improve energy-aware (EAS) balancing logic & metrics.
- Fix & improve the uclamp metrics.
- Fix task migration (taskset) corner case on !CONFIG_CPUSET.
- Fix RT and deadline utilization tracking across policy changes
- Introduce a "burstable" CFS controller via cgroups, which allows
bursty CPU-bound workloads to borrow a bit against their future
quota to improve overall latencies & batching. Can be tweaked
via /sys/fs/cgroup/cpu/<X>/cpu.cfs_burst_us.
- Rework assymetric topology/capacity detection & handling.
- Scheduler statistics & tooling:
- Disable delayacct by default, but add a sysctl to enable
it at runtime if tooling needs it. Use static keys and
other optimizations to make it more palatable.
- Use sched_clock() in delayacct, instead of ktime_get_ns().
- Misc cleanups and fixes.

Locking changes for this cycle:

and all the transitory facilities and #ifdefs.
Much reduction in complexity from that series:
63 files changed, 756 insertions(+), 4094 deletions(-)
- Self-test enhancements
- Futexes:
- Add the new FUTEX_LOCK_PI2 ABI, which is a variant that
doesn't set FLAGS_CLOCKRT (.e. uses CLOCK_MONOTONIC).
[ The temptation to repurpose FUTEX_LOCK_PI's implicit
setting of FLAGS_CLOCKRT & invert the flag's meaning

spi: Updates for v5.14
The biggest single thing in the diffstat here is a massive overhaul of
the PXA2xx driver from Andy Shevchenko (the IP is still in use on modern
Intel systems), though we also have quite a lot of core work as well:
- Better support for mixing native and GPIO chip selects also from
Andy.
- Support for devices with multiple chip selects from Sebastian
Reichel.
- Helper for polling status registers in spi-mem from Patrice Chotard.
- Support for Renesas RZ/N1 and Rockchip RV1126.

regulator: Updates for v5.14
The main core change this release is generic support for handling of
hardware errors from Matti Vaittinen, including some small updates to
the reboot and thermal code so we can share support for powering off the
system if things are going wrong enough. Otherwise this release we've
mainly seen the addition of new drivers, including MT6359 which has
pulled in some small changes from the MFD tree for build dependencies.
- Support for controlling the trigger points for hardware error
detection, and shared handlers for this.
- Support for Maxim MAX8993, Mediatek MT6359 and MT6359P, Qualcomm
PM8226 and SA8115P-ADP, and Sylergy TCS4526.
