xfs: improve CIL scalability
This series aims to improve the scalability of XFS transaction
commits on large CPU count machines. My 32p machine hits contention
limits in xlog_cil_commit() at about 700,000 transaction commits a
section. It hits this at 16 thread workloads, and 32 thread
workloads go no faster and just burn CPU on the CIL spinlocks.
This patchset gets rid of spinlocks and global serialisation points
in the xlog_cil_commit() path. It does this by moving to a
combination of per-cpu counters, unordered per-cpu lists and
post-ordered per-cpu lists.
This results in transaction commit rates exceeding 1.4 million
commits/s under unlink certain workloads, and while the log lock
contention is largely gone there is still significant lock
contention in the VFS (dentry cache, inode cache and security layers)
at >600,000 transactions/s that still limit scalability.
The changes to the CIL accounting and behaviour, combined with the
structural changes to xlog_write() in prior patchsets make the
per-cpu restructuring possible and sane. This allows us to move to
precalculated reservation requirements that allow for reservation
stealing to be accounted across multiple CPUs accurately.
That is, instead of trying to account for continuation log opheaders
on a "growth" basis, we pre-calculate how many iclogs we'll need to
write out a maximally sized CIL checkpoint and steal that reserveD
that space one commit at a time until the CIL has a full
reservation. If we ever run a commit when we are already at the hard
limit (because post-throttling) we simply take an extra reservation
from each commit that is run when over the limit. Hence we don't
need to do space usage math in the fast path and so never need to
sum the per-cpu counters in this fast path.
Similarly, per-cpu lists have the problem of ordering - we can't
remove an item from a per-cpu list if we want to move it forward in
the CIL. We solve this problem by using an atomic counter to give
every commit a sequence number that is copied into the log items in
that transaction. Hence relogging items just overwrites the sequence
number in the log item, and does not move it in the per-cpu lists.
Once we reaggregate the per-cpu lists back into a single list in the
CIL push work, we can run it through list-sort() and reorder it back
into a globally ordered list. This costs a bit of CPU time, but now
that the CIL can run multiple works and pipelines properly, this is
not a limiting factor for performance. It does increase fsync
latency when the CIL is full, but workloads issuing large numbers of
fsync()s or sync transactions end up with very small CILs and so the
latency impact or sorting is not measurable for such workloads.
OVerall, this pushes the transaction commit bottleneck out to the
lockless reservation grant head updates. These atomic updates don't
start to be a limiting fact until > 1.5 million transactions/s are
being run, at which point the accounting functions start to show up
in profiles as the highest CPU users. Still, this series doubles
transaction throughput without increasing CPU usage before we get
to that cacheline contention breakdown point...

A description is missing for the net.core.high_order_alloc_disable
option in admin-guide/sysctl/net.rst ; add it. The above sysctl option
was introduced by commit ce27ec60648d ("net: add high_order_alloc_disable
sysctl/static key").
Thanks to Eric for running again the benchmark cited in the above
commit, showing this knob is now mostly of historical importance.

The gpio-keys DT schema matches all properties with a wide pattern and
applies specific schema to children. This has drawback - all regular
properties are also matched and are silently ignored, even if they are
not described in schema. Basically this allows any non-object property
to be present.
Enforce specific naming pattern for children (keys) to narrow the
pattern thus do not match other properties. This will require all
children to be properly prefixed or suffixed (button, event, switch or
key).
Removal of "if:" within patternProperties causes drop of one indentation
level, but there are no other changes in the affected block.

The "Run Tests on qemu" section of run_wrapper.rst had a few issues left
over from the last big documentation refactor[1]:
- It referenced a non_uml.rst page, which was integrated into the other
pages (including run_wrapper.rst).
- It skimmed over the use of --arch= and --cross_compile= in favour of
using a custom --qemu_config. Since most users will want to use the
former, let's give examples.
Remove the reference to the non-existant page, and add a couple of
examples to encourage the use of --arch= and --cross_compile=.
With this change, there should be no more broken references in the KUnit
documentation (i.e., the one mentioned in [2] is gone).

Convert the Samsung SoC JPEG codec bindings to DT schema.
The original bindings were quite old and incomplete, so change during
conversion:
1. Add typical (already used) properties like iommus and power domains.
2. Document samsung,exynos4212-jpeg compatible (already used in DTS and
driver).
3. List clocks per each variant.
