iov_iter work, part 1 - isolated cleanups and optimizations.
One of the goals is to reduce the overhead of using ->read_iter()
and ->write_iter() instead of ->read()/->write(); new_sync_{read,write}()
has a surprising amount of overhead, in particular inside iocb_flags().
That's why the beginning of the series is in this pile; it's not directly
iov_iter-related, but it's a part of the same work...

Main part here is making parallel lookups safe for RT - making
sure preemption is disabled in start_dir_add()/ end_dir_add() sections (on non-RT it's automatic, on RT it needs to to be done explicitly) and moving wakeups from __d_lookup_done() inside of such to the end of those sections. Wakeups can be safely delayed for as long as ->d_lock on in-lookup dentry is held; proving that has caught a bug in d_add_ci() that allows memory corruption when sufficiently bogus ntfs (or case-insensitive xfs) image is mounted.

Several core optimizations:
* threadgroup_rwsem write locking is skipped when configuring controllers in
empty subtrees. Combined with CLONE_INTO_CGROUP, this allows the common
static usage pattern to not grab threadgroup_rwsem at all (glibc still
doesn't seem ready for CLONE_INTO_CGROUP unfortunately).
* threadgroup_rwsem used to be put into non-percpu mode by default due to
latency concerns in specific use cases. There's no reason for everyone
else to pay for it. Make the behavior optional.
* psi no longer allocates memory when disabled.

linux-kselftest-kunit-5.20-rc1
This KUnit update for Linux 5.20-rc1 consists of several fixes and an
important feature to discourage running KUnit tests on production
systems. Running tests on a production system could leave the system
in a bad state. This new feature adds:
- adds a new taint type, TAINT_TEST to signal that a test has been run.
This should discourage people from running these tests on production
systems, and to make it easier to tell if tests have been run
accidentally (by loading the wrong configuration, etc.)
- several documentation and tool enhancements and fixes.

This was a moderately busy cycle for documentation, but nothing all that
earth-shaking:
- More Chinese translations, and an update to the Italian translations.
The Japanese, Korean, and traditional Chinese translations are
more-or-less unmaintained at this point, instead.
- Some build-system performance improvements.

RCU pull request for v5.20 (or whatever)
This pull request contains the following branches: doc.2022.06.21a: Documentation updates. fixes.2022.07.19a: Miscellaneous fixes. nocb.2022.07.19a: Callback-offload updates, perhaps most notably a new RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to be offloaded at boot time, regardless of kernel boot parameters.

In addition, a new RCU_NOCB_CPU_CB_BOOST kernel boot parameter prevents offloaded callbacks from interfering with real-time workloads and with energy-efficiency mechanisms. poll.2022.07.21a: Polled grace-period updates, perhaps most notably making these APIs account for both normal and expedited grace periods. rcu-tasks.2022.06.21a: Tasks RCU updates, perhaps most notably reducing the CPU overhead of RCU tasks trace grace periods by more than a factor of two on a system with 15,000 tasks.

Merge tag 'random-6.0-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld:
"Though there's been a decent amount of RNG-related development during
this last cycle, not all of it is coming through this tree, as this
cycle saw a shift toward tackling early boot time seeding issues,
which took place in other trees as well.
Here's a summary of the various patches:
- The CONFIG_ARCH_RANDOM .config option and the "nordrand" boot
option have been removed, as they overlapped with the more widely
supported and more sensible options, CONFIG_RANDOM_TRUST_CPU and
"random.trust_cpu". This change allowed simplifying a bit of arch
code.
- x86's RDRAND boot time test has been made a bit more robust, with
RDRAND disabled if it's clearly producing bogus results. This would
be a tip.git commit, technically, but I took it through random.git
to avoid a large merge conflict.
- The RNG has long since mixed in a timestamp very early in boot, on
the premise that a computer that does the same things, but does so
starting at different points in wall time, could be made to still
produce a different RNG state. Unfortunately, the clock isn't set
early in boot on all systems, so now we mix in that timestamp when
the time is actually set.
- User Mode Linux now uses the host OS's getrandom() syscall to
generate a bootloader RNG seed and later on treats getrandom() as
the platform's RDRAND-like faculty.
- The arch_get_random_{seed_,}_long() family of functions is now
arch_get_random_{seed_,}_longs(), which enables certain platforms,
such as s390, to exploit considerable performance advantages from
requesting multiple CPU random numbers at once, while at the same
time compiling down to the same code as before on platforms like
x86.
- A small cleanup changing a cmpxchg() into a try_cmpxchg(), from
Uros.
- A comment spelling fix"
More info about other random number changes that come in through various
architecture trees in the full commentary in the pull request:

Pull selinux updates from Paul Moore:
"A relatively small set of patches for SELinux this time, eight patches
in total with really only one significant change.
The highlights are:
- Add support for proper labeling of memfd_secret anonymous inodes.
This will allow LSMs that implement the anonymous inode hooks to
apply security policy to memfd_secret() fds.
- Various small improvements to memory management: fixed leaks, freed
memory when needed, boundary checks.
- Hardened the selinux_audit_data struct with __randomize_layout.
- A minor documentation tweak to fix a formatting/style issue"

This isn't very efficient, and we even have specific code in io-wq to serialize buffered writes to the same inode to avoid further inefficiencies with thread offload. This is particularly sad since most buffered writes don't block, they simply copy data to a page and dirty it. With this pull request, we can handle buffered writes a lot more effiently. If balance_dirty_pages() needs to block, we back off on writes as indicated. This improves buffered write support by 2-3x.

The code is organized a lot better like this, and io_uring.c is now < 4K LOC (me). - Deprecate the epoll_ctl opcode. It'll still work, just trigger a warning once if used.

- Remove as unnecessary call to dev_err() as the error is already
printed by the failing function on u8500 (Yang Li).
- Register the thermal zones as hwmon sensors for the Qcom thermal
sensors (Dmitry Baryshkov).
- Fix 'tmon' tool compilation issue by adding phtread.h include
(Markus Mayer).

spi: Updates for v5.20
The big update this time around is some excellent work from David Jander
who went through the fast path and really eliminated overheads, meaning
that we are seeing a huge reduction in the time spent between transfers
for single threaded clients. Benchmarking has been coming out at about a
halving of overhead which is clearly visible in system level usage that
stresses SPI like some CAN and IIO applications, especially with small
transfers. Thanks to David for taking the time to drill down into this
and push the work upstream.
Otherwise there's been a bunch of new device support and the usual
- Optimisation of the fast path, particularly around the number and
types of locking operations, from David Jander.
- Support for Arbel NPCM845, HP GXP, Intel Meteor Lake and Thunder Bay,
MediaTek MT8188 and MT8365, Microchip FPGAs, nVidia Tegra 241 and
Samsung Exynos Auto v9 and 4210.

regulator: Updates for v5.20
This has been a fairly quiet release for the regulator API, a few new
drivers and a small API update:
- Support for specifying an initial load as part of requesting
regulators through the bulk API.
- Support for Maxim MAX597x, Qualcomm PM8074, PM8909 and Realtek RT5120
devices.

regmap: Updates for v5.20
The big thing this release is a big cleanup of the interrupt code from
Aidan MacDonald, plus a few new API updates:
- Rework of the interrupt code, making it much simpler and easier to
extend.
- Support for device specific update bits operations with devices that
otherwise use bitstream interfaces.
- Support for bit operations on fields as well as whole registers.

fs: don't call ->writepage from __mpage_writepage
All callers of mpage_writepage use block_write_full_page as their ->writepage implementation when called from mpage_writepages (although for ntfs3 this is obsfucated a bit). Just call block_write_full_page directly instead of going through the ->writepage indirection.

jfs: stop using the nobh helper
The nobh mode is an obscure feature to save lowlevel for large memory 32-bit configurations while trading for much slower performance and has been long obsolete.
