Pull scheduler updates from Borislav Petkov:
"Mostly minor things this time; some highlights:
- core-sched: Add 'Forced Idle' accounting; this allows to track how
much CPU time is 'lost' due to core scheduling constraints.
- psi: Fix for MEM_FULL; a task running reclaim would be counted as a
runnable task and prevent MEM_FULL from being reported.
- cpuacct: Long standing fixes for some cgroup accounting issues.
- rt: Bandwidth timer could, under unusual circumstances, be failed
to armed, leading to indefinite throttling."

Pull xfs updates from Darrick Wong:
"The big new feature here is that the mount code now only bothers to
try to free stale COW staging extents if the fs unmounted uncleanly.
This should reduce mount times, particularly on filesystems supporting
reflink and containing a large number of allocation groups.
Everything else this cycle are bugfixes, as the iomap folios
conversion should be plenty enough excitement for anyone. That and I
ran out of brain bandwidth after Thanksgiving last year.
Summary:
- Fix log recovery with da btree buffers when metauuid is in use.
- Fix type coercion problems in xattr buffer size validation.
- Fix a bug in online scrub dir leaf bestcount checking.
- Only run COW recovery when recovering the log.
- Fix symlink target buffer UAF problems and symlink locking problems
by not exposing xfs innards to the VFS.
- Fix incorrect quotaoff lock usage.
- Don't let transactions cancel cleanly if they have deferred work
items attached.
- Fix a UAF when we're deciding if we need to relog an intent item.
- Reduce kvmalloc overhead for log shadow buffers.
- Clean up sysfs attr group usage.
- Fix a bug where scrub's bmap/rmap checking could race with a quota
file block allocation due to insufficient locking.
- Teach scrub to complain about invalid project ids"

Pull btrfs updates from David Sterba:
"This end of the year branch is intentionally not that exciting. Most
of the changes are under the hood, but there are some minor user
visible improvements and several performance improvements too.
Features:
- make send work with concurrent block group relocation.
We're not allowed to prevent send failing or silently producing
some bad stream but with more fine grained locking and checks it's
possible. The send vs deduplication exclusion could reuse the same
logic in the future.
- new exclusive operation 'balance paused' to allow adding a device
to filesystem with paused balance
- new sysfs file for fsid stored in the per-device directory to help
distinguish devices when seeding is enabled, the fsid may differ
from the one reported by the filesystem
Performance improvements:
- less metadata needed for directory logging, directory deletion is
20-40% faster
- in zoned mode, cache zone information during mount to speed up
repeated queries (about 50% speedup)
- free space tree entries get indexed and searched by size (latency
-30%, search run time -30%)
- less contention in tree node locking when inserting a key and no
splits are needed (files/sec in fsmark improves by 1-20%)
Fixes:
- fix ENOSPC failure when attempting direct IO write into NOCOW range
- fix deadlock between quota enable and other quota operations
- global reserve minimum calculations fixed to account for free space
tree
- in zoned mode, fix condition for chunk allocation that may not find
the right zone for reuse and could lead to early ENOSPC
Core:
- global reserve stealing got simplified and cleaned up in evict
- remove async transaction commit based on manual transaction refs,
reuse existing kthread and mechanisms to let it commit transaction
before timeout
- preparatory work for extent tree v2, add wrappers for global tree
roots, truncation path cleanups
- remove readahead framework, it's a bit overengineered and used only
for scrub, and yet it does not cover all its needs, there is
another readahead built in the b-tree search that is now used,
performance drop on HDD is about 5% which is acceptable and scrub
is often throttled anyway, on SSDs there's no reported drop but
slight improvement
- self tests report extent tree state when error occurs
- replace assert with debugging information when an uncommitted
transaction is found at unmount time
Other:
- error handling improvements
- other cleanups and refactoring"

"In this cycle, tail-packing data inline for compressed files is now
supported so that tail pcluster can be stored and read together with
inode metadata in order to save data I/O and storage space.

fscache features, we also introduce meta buffers to get rid of

Pull fs idmapping updates from Christian Brauner:
"This contains the work to enable the idmapping infrastructure to
support idmapped mounts of filesystems mounted with an idmapping.
In addition this contains various cleanups that avoid repeated
open-coding of the same functionality and simplify the code in quite a
few places.
We also finish the renaming of the mapping helpers we started a few
kernel releases back and move them to a dedicated header to not
continue polluting the fs header needlessly with low-level idmapping
helpers. With this series the fs header only contains idmapping
helpers that interact with fs objects.
Currently we only support idmapped mounts for filesystems mounted
without an idmapping themselves. This was a conscious decision
mentioned in multiple places (cf. [1]).
As explained at length in [3] it is perfectly fine to extend support
for idmapped mounts to filesystem's mounted with an idmapping should
the need arise. The need has been there for some time now (cf. [2]).
Before we can port any filesystem that is mountable with an idmapping
to support idmapped mounts in the coming cycles, we need to first
extend the mapping helpers to account for the filesystem's idmapping.
This again, is explained at length in our documentation at [3] and
also in the individual commit messages so here's an overview.
Currently, the low-level mapping helpers implement the remapping
algorithms described in [3] in a simplified manner as we could rely on
the fact that all filesystems supporting idmapped mounts are mounted
without an idmapping.
In contrast, filesystems mounted with an idmapping are very likely to
not use an identity mapping and will instead use a non-identity
mapping. So the translation step from or into the filesystem's
idmapping in the remapping algorithm cannot be skipped for such
filesystems.
Non-idmapped filesystems and filesystems not supporting idmapped
mounts are unaffected by this change as the remapping algorithms can
take the same shortcut as before. If the low-level helpers detect that
they are dealing with an idmapped mount but the underlying filesystem
is mounted without an idmapping we can rely on the previous shortcut
and can continue to skip the translation step from or into the
filesystem's idmapping. And of course, if the low-level helpers detect
that they are not dealing with an idmapped mount they can simply
return the relevant id unchanged; no remapping needs to be performed
at all.
These checks guarantee that only the minimal amount of work is
performed. As before, if idmapped mounts aren't used the low-level
helpers are idempotent and no work is performed at all"

Pull gpio updates from Bartosz Golaszewski:
"The gpio-sim module is back, this time without any changes to
configfs. This results in a less elegant user-space interface but I
never got any follow-up on the committable items and didn't want to
delay this module for several more months.
Other than that we have support for several new models and some
support going away. We started working on converting GPIO drivers to
using fwnode exclusively in order to limit references to OF symbols to
gpiolib-of.c exclusively. We also have regular tweaks and improvements
all over the place.
Summary:
- new testing module: gpio-sim that is scheduled to replace
gpio-mockup
- initial changes aiming at converting all GPIO drivers to using the
fwnode interface and limiting any references to OF symbols to
gpiolib-of.c
- add support for Tegra234 and Tegra241 to gpio-tegra186
- add support for new models (SSD201 and SSD202D) to gpio-msc313
- add basic support for interrupts to gpio-aggregator
- add support for AMDIF031 HID device to gpio-amdpt
- drop support for unused platforms in gpio-xlp
- cleanup leftovers from the removal of the legacy Samsung Exynos
GPIO driver
- use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make
PREEMPT_RT happy
- generalize the common 'ngpios' device property by reading it in the
core gpiolib code so that we can remove duplicate reads from
drivers
- allow line names from device properties to override names set by
drivers
- code shrink in gpiod_add_lookup_table()
- add new model to the DT bindings for gpio-vf610
- convert DT bindings for tegra devices to YAML
- improvements to interrupt handling in gpio-rcar and gpio-rockchip
- updates to intel drivers from Andy (details in the merge commit)
- some minor tweaks, improvements and coding-style fixes all around
the subsystem"

Pull printk updates from Petr Mladek:
- Remove some twists in the console registration code. It does not
change the existing behavior except for one corner case. The proper
default console (with tty binding) will be registered again even when
it has been removed in the meantime. It is actually a bug fix.
Anyway, this modified behavior requires some manual interaction.

Pull workqueue updates from Tejun Heo:
- The code around workqueue scheduler hooks got reorganized early 2019
which unfortuately introdued a couple subtle and rare race conditions
where preemption can mangle internal workqueue state triggering a
WARN and possibly causing a stall or at least delay in execution.
Frederic fixed both early December and the fixes were sitting in
for-5.16-fixes which I forgot to push. They are here now. I'll
forward them to stable after they land.
- The scheduler hook reorganization has more implicatoins for workqueue
code in that the hooks are now more strictly synchronized and thus
the interacting operations can become more straight-forward.
Lai is in the process of simplifying workqueue code and this pull
request contains some of the patches.

A task can end up indefinitely sleeping in do_select() ->
poll_schedule_timeout() when the following race happens:
TASK1 (thread1) TASK2 TASK1 (thread2)
do_select()
setup poll_wqueues table
with 'fd'
write data to 'fd'
pollwake()
table->triggered = 1
closes 'fd' thread1 is
waiting for
poll_schedule_timeout()
- sees table->triggered
table->triggered = 0
return -EINTR
loop back in do_select()
But at this point when TASK1 loops back, the fdget() in the setup of
poll_wqueues fails. So now so we never find 'fd' is ready for reading
and sleep in poll_schedule_timeout() indefinitely.
Treat an fd that got closed as a fd on which some event happened. This
makes sure cannot block indefinitely in do_select().
Another option would be to return -EBADF in this case but that has a
potential of subtly breaking applications that excercise this behavior
and it happens to work for them. So returning fd as active seems like a
safer choice.

Before this patch, glock dumps would not dump the gl_object for iopen
glocks. This information can help us debug problems related to eviction:
when AN iopen glock is blocked we can see the status of its underlying
inode and its flags, etc.

With CONFIG_KALLSYMS_ALL=y, the function is_ksym_addr() is used to
determine if a symbol is from inside the kernel range. For that the
given symbol address is checked if it's inside the _stext to _end range.
Although this is correct, some architectures (e.g. parisc) may have the
init area before the _stext address and as such the check in
is_ksym_addr() fails. By extending the range check to include the init
section, __is_kernel() will now detect symbols in this range as well.
This fixes an issue on parisc where addresses of kernel functions in
init sections aren't resolved to their symbol names.

No need to have an own hpmc_stack. Just re-use the toc_stack of the
monarch CPU as either a TOC or a HPMC will happen at the same time.
This reduces the kernel memory footprint by 16k.
Signed-off-by: Helge Deller <deller@gmx.de>

Before this patch, the TOC code used a pre-allocated stack of 16kb for
each possible CPU. That space overhead was the reason why the TOC
feature wasn't enabled by default for 32-bit kernels.
This patch rewrites the TOC code to use a per-cpu stack. That way we use
much less memory now and as such we enable the TOC feature by default on
all kernels.
Additionally the dump of the registers and the stacktrace wasn't
serialized, which led to multiple CPUs printing the stack backtrace at
once which rendered the output unreadable.
Now the backtraces are nicely serialized by a lock.
