This is based on an earlier blog post at people.kernel.org,
it describes the concepts about page tables that were hardest
for me to grasp when dealing with them for the first time,
such as the prevalent three-letter acronyms pfn, pgd, p4d,
pud, pmd and pte.
I don't know if this is what people want, but it's what I would
have wanted. The wording, introduction, choice of initial subjects
and choice of style is mine.
I discussed at one point with Mike Rapoport to bring this into
the kernel documentation, so here is a small proposal.
The current form is augmented in response to feedback from
Mike Rapoport, Matthew Wilcox, Jonathan Cameron, Kuan-Ying Lee,
Randy Dunlap and Bagas Sanjaya.

Prior to this commit, the kernel docs writing guide spent over a page
describing exactly how *not* to write tables into the kernel docs,
without providing a example about the desired format.
This patch provides a positive example first in the guide so that it's
harder to miss, then leaves the existing less desirable approach below
for contributors to follow if they have some stronger justification for
why to use that approach.

This basically rewrites the 'Prioritize work on fixing regressions'
section of Documentation/process/handling-regressions.rst for various
reasons. Among them: some things were too demanding, some didn't align
well with the usual workflows, and some apparently were not clear enough
-- and of course a few things were missing that would be good to have in
there.
Linus for example recently stated that regressions introduced during the
past year should be handled similarly to regressions from the current
cycle, if it's a clear fix with no semantic subtlety. His exact
wording[1] didn't fit well into the text structure, but the author tried
to stick close to the apparent intention.
It was a noble goal from the original author to state "[prevent
situations that might force users to] continue running an outdated and
thus potentially insecure kernel version for more than two weeks after a
regression's culprit was identified"; this directly led to the goal "fix
regression in mainline within one week, if the issue made it into a
stable/longterm kernel", because the stable team needs time to pick up
and prepare a new release. But apparently all that was a bit too
demanding.
That "one week" target for example doesn't align well with the usual
habits of the subsystem maintainers, which normally send their fixes to
Linus once a week; and it doesn't align too well with stable/longterm
releases either, which often enter a -rc phase on Mondays or Tuesdays
and then are released two to three days later. And asking developers to
create, review, and mainline fixes within one week might be too much to
ask for in general. Hence tone the general goal down to three weeks and
use an approach that better aligns with the usual merging and release
habits.
While at it, also make the rules of thumb a bit easier to follow by
grouping them by topic (e.g. generic things, timing, procedures, ...).
Also add text for a few cases where recent discussions showed they need
covering. Among them are multiple points that better explain the
relations to stable and longterm kernels and the team that manages them;
they and the group seperators are the primary reason why this whole
section sadly grew somewhat in the rewrite.
The group about those relations led to one addition the author came up
with without any precedent from Linus: the text now tells developers to
add a stable tag for any regression that made it into a proper mainline
release during the past 12 months. This is meant to ensure the stable
team will definitely notice any fixes for recent regressions. That
includes those introduced shortly before a new mainline release and
found right after it; without such a rule the stable team might miss the
fix, which then would only reach users after weeks or months with later
releases.
Note, the aspect "Do not consider regressions from the current cycle as
something that can wait till the cycle's end [...]" might look like an
addition, but was kinda was in the old text as well -- but only
indirectly. That apparently was too subtle, as many developers seem to
assume waiting till the end of the cycle is fine (even for build
fixes).
In practice this was especially problematic when a cause of a regression
made it into a proper release (either directly or through a backport). A
revert performed by Linus shortly before the 6.3 release illustrated
that[2], as the developer of the culprit had been willing to revert the
culprit about three weeks earlier already -- but didn't do so when a fix
came into sight and a maintainer suggested it can wait. Due to that the
issue in the end plagued users of 6.2.y at least two weeks longer than
necessary, as the fix in the end didn't become ready in time. This issue
in fact could have been resolved one or two additional weeks earlier, if
the developer had reverted the culprit shortly after it had been
identified (which even the old version of the text suggest to do in such
cases).

Fixes the following error in the docs build that occurs with recent
versions of Sphinx when parsing kerneldocs for a function with the
'__force' macro in its signature:
./include/linux/err.h:51: WARNING: Error in declarator or parameters
Error in declarator or parameters
Invalid C declaration: Expected identifier, got keyword: void [error at 35]
void * ERR_CAST (__force const void *ptr)
-----------------------------------^
Currently, almost all of the few in-signature occurrences of '__force'
are in the error pointer functions. Of those, ERR_CAST() is the only
one with kerneldocs, but the kerneldocs aren't even being used to
generate documentation. This change will allow all the error pointer
functions to be properly documented.
In addition to '__force', <linux/compiler_types.h> also defines
'__nocast', '__safe', and '__private'. These are not currently used in
any function signatures and do not need to be added to the docs config.

The descriptions of certain KVM related kernel parameters can be
confusing. They state "Disable ...," which may make people think that
setting them to 1 will disable the associated feature when in fact the
opposite is true.
This commit addresses this issue by revising the descriptions of these
parameters by using "Control..." rather than "Enable/Disable...".
1==enabled or 0==disabled can be communicated by the description of
default value such as "1 (enabled)" or "0 (disabled)".
Also update the description of KVM's default value for kvm-intel.nested
as it is enabled by default.

assigned-clocks are a dependency of clocks, however the dtschema has
limitation and expects clocks to be present in the binding using
assigned-clocks, not in other referenced bindings. The clocks were
defined in common fsl,imx6q-pcie-common.yaml, which is referenced by
fsl,imx6q-pcie-ep.yaml. The fsl,imx6q-pcie-ep.yaml used assigned-clocks
thus leading to warnings:
Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.example.dtb: pcie-ep@33800000:
Unevaluated properties are not allowed ('assigned-clock-parents', 'assigned-clock-rates', 'assigned-clocks' were unexpected)

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull more tracing updates from Steven Rostedt:
- Make buffer_percent read/write.
The buffer_percent file is how users can state how long to block on
the tracing buffer depending on how much is in the buffer. When it
hits the "buffer_percent" it will wake the task waiting on the
buffer. For some reason it was set to read-only.
This was not noticed because testing was done as root without
SELinux, but with SELinux it will prevent even root to write to it
without having CAP_DAC_OVERRIDE.
- The "touched_functions" was added this merge window, but one of the
reasons for adding it was not implemented.
That was to show what functions were not only touched, but had either
a direct trampoline attached to it, or a kprobe or live kernel
patching that can "hijack" the function to run a different function.
The point is to know if there's functions in the kernel that may not
be behaving as the kernel code shows. This can be used for debugging.
TODO: Add this information to kernel oops too.

If a function had ever had IPMODIFY or DIRECT attached to it, where this
is how live kernel patching and BPF overrides work, mark them and display
an "M" in the enabled_functions and touched_functions files. This can be
used for debugging. If a function had been modified and later there's a bug
in the code related to that function, this can be used to know if the cause
is possibly from a live kernel patch or a BPF program that changed the
behavior of the code.
Also update the documentation on the enabled_functions and
touched_functions output, as it was missing direct callers and CALL_OPS.
And include this new modify attribute.

Seemingly I mis-implemented the dependencies here. The OpenSBI docs only
point out that the "riscv,event-to-mhpmcounters property is mandatory if
riscv,event-to-mhpmevent is present". It never claims that
riscv,event-to-mhpmcounters requires riscv,event-to-mhpmevent.
Drop the dependency of riscv,event-to-mhpmcounters on
riscv,event-to-mhpmevent.

"This includes a number of patches that didn't quite make the cut last
merge window while we addressed some outstanding issues and review
comments. It includes some new caching modes for those that only want
readahead caches and reworks how we do writeback caching so we are not
keeping extra references around which both causes performance problems
and uses lots of additional resources on the server.
It also includes a new flag to force disabling of xattrs which can
also cause major performance issues, particularly if the underlying
filesystem on the server doesn't support them.
Finally it adds a couple of additional mount options to better support
directio and enabling caches when the server doesn't support
qid.version.

its own patch where I forgot to propagate an embarassing bit-logic fix
