docs: clarify rules wrt tagging other people

Point out that explicit permission is usually needed to tag other people
in changes, but mention that implicit permission can be sufficient in
certain cases. This fixes slight inconsistencies between Reported-by:
and Suggested-by: and makes the usage more intuitive.

While at it, explicitly mention the dangers of our bugzilla instance, as
it makes it easy to forget that email addresses visible there are only
shown to logged-in users.

The latter is not a theoretical issue, as one maintainer mentioned that
his employer received a EU GDPR (general data protection regulation)
complaint after exposing a email address used in bugzilla through a tag
in a patch description.

Following a recent discussion at last Plumbers, John Stultz, Sumit
Sewal, TJ Mercier and I came to an agreement that we should document
what the dma-buf heaps names are expected to be, and what the buffers
attributes you'll get should be documented.

Let's create that doc to make sure those attributes and names are

docs/.../submit-checklist: Use Documentation/admin-guide/abi.rst for cross-ref of README

Commit fb12098d8ee4 ("docs: submit-checklist: Allow creating
cross-references for ABI README") assumes that the path of
"Documentation/ABI/README" would be converted to a cross-ref to
the README.

However, as the README is included by the "kernel-abi" directive
at Documentation/admin-guide/abi.rst, the expected conversion
does not happen.

Instead, use the path where the "kernel-abi" directive exists for
the conversion to work.  Restore the original path of README in
inline-literal form as an additional note for readers of the .rst
file.

Apply the same changes for translations.

Documentation/CoC: Spell out the TAB role in enforcement decisions

Updates the document to clearly describe the scope and role the TAB plays
in making decisions on unresolved violations. If and when the CoC has to
make a call on instituting a ban, it doesn't act without the TAB's approval
and only when the TAB approves it with 2/3 vote in favor of the measure.

These changes ensure that the TAB role and its oversight on CoC measures
is consistently described throughout the document.

scripts: get_feat.pl: substitute s390x with s390

Both get_feat.pl and list-arch.sh use uname -m to get the machine hardware
name to figure out the current architecture if no architecture is specified
with a command line option.

This doesn't work for s390, since for 64 bit kernels the hardware name is
s390x, while the architecture name within the kernel, as well as in all
feature files is s390.

Therefore substitute s390x with s390 similar to what is already done for
x86_64 and i386.

This is a brand-new translation against
commit 2783096fb1dd ("docs: submit-checklist: Expand on build tests

ja_JP/SubmitChecklist, which has never updated since 2008 except for
trivial changes not involving translation.

docs: iostats: Rewrite intro, remove outdated formats

The introduction discussed stat file formats for very old kernel versions,
which obscured key information that readers may find useful. Additionally,
the example file contents and the reference to "15 fields" did not account
for the flush fields added in b6866318657 ("block: add iostat counters for
flush requests") [1].

Rewrite the introduction to focus only on the current kernel's disk I/O stat
file formats. Also, clean up wording for conciseness.

Merge branch 'mauro' into docs-mw

Mauro says:

This series  increases the minimal requirements for Sphinx and Python, and
drop some backward-compatible code from Sphinx extension.

Looking at Sphinx release dates:

Release 2.4.0 (released Feb 09, 2020)
Release 2.4.4 (released Mar 05, 2020) (current minimal requirement)
Release 3.4.0 (released Dec 20, 2020)
Release 3.4.3 (released Jan 08, 2021)

(https://www.sphinx-doc.org/en/master/changes/index.html)

And Python release dates, we have:

Python Release date
3.5 2015-09-13    (current minimal requirement)
3.6 2016-12-23
3.7  2018-06-27
3.8  2019-10-14
3.9  2020-10-05
3.10 2021-10-04

(according with https://en.wikipedia.org/w/index.php?title=History_of_Python)

The new minimal requirements are now compatible with the toolset available on Jan, 2021,
e.g.:
- Sphinx 3.4.3;
- Python 3.9

The new Sphinx minimal requirement allows dropping all backward-compatible code
we have at kernel-doc and at Sphinx extensions.

The new Python minimal requirement also matches the current required level for
almost  all scripts (*).

Those matches a 4-years old toolchain, which sounds a reasonable period
of time, as Python/Sphinx aren't required for the Kernel build.

(*) Except for a couple scripts inside tools that require python 3.10:

    $ vermin -v $(git ls-files '*.py')|grep 3.10
    !2, 3.10     tools/net/sunrpc/xdrgen/generators/__init__.py
    !2, 3.10     tools/net/sunrpc/xdrgen/generators/program.py
    !2, 3.10     tools/net/sunrpc/xdrgen/subcmds/source.py
    !2, 3.10     tools/net/sunrpc/xdrgen/xdr_ast.py
    !2, 3.10     tools/perf/scripts/python/mem-phys-addr.py
    !2, 3.10     tools/power/cpupower/bindings/python/test_raw_pylibcpupower.py

Such scripts aren't required for Kernel builds, so it should be OK to set minimal
python version to 3.9.

scripts/kernel-doc: drop Sphinx version check

As the current minimal supported Sphinx version is 3.4.3, drop
support for older versions.

scripts/kernel-doc: remove an obscure logic from kernel-doc

Kernel-doc has an obscure logic that uses an external file
to map files via a .tmp_filelist.txt file stored at the current
directory. The rationale for such code predates git time,
as it was added on Kernel v2.4.5.5, with the following description:

# 26/05/2001 -         Support for separate source and object trees.
#              Return error code.
#              Keith Owens <kaos@ocs.com.au>

from commit 396a6123577d ("v2.4.5.4 -> v2.4.5.5") at the historic
tree:
https://git.kernel.org/pub/scm/linux/kernel/git/history/history.git/

Support for separate source and object trees is now done on a different
way via make O=<object>.

There's no logic to create such file, so it sounds to me that this is
just dead code.

So, drop it.

Merge branch 'mauro' into docs-mw

Mauro says:

This series replace get_abi.pl with a Python version.

I originally started it due to some issues I noticed when searching for
ABI symbols. While I could just go ahead and fix the already existing
script, I noticed that the script maintainance didn't have much care over
all those years, probably because it is easier to find Python programmers
those days.

Also, the code is complex and was not using modules or classes and
were using lots of global variables.

So, I decided to rewrite it in Python. I started with a manual conversion
for each function. Yet, to avoid future maintainership issues, I opted to
divide the main code on three classes, each on a sepaparate file.

Just like the original RFC, I opted to keep the Sphinx kernel-abi module
on three different phases:

- call get_abi.py as an exec file;
- import AbiParser on a minimal integration scenario;
- cleanup the code to avoid needing to parse line numbers from the text.

This way, if something goes wrong, it would be easier to just revert any
offending patches, It also provides a better rationale about what each
logical change is doing.

The initial patches on this series do some preparation work and
cleans some ABI symbol bugs that lack ":" delimiter.

scripts/get_abi.pl: drop now obsoleted script

scripts/get_abi.py: add support for undefined ABIs

The undefined logic is complex and has lots of magic on it.

Implement it, using the same algorithm we have at get_abi.pl. Yet,
some tweaks to optimize performance and to make the code simpler
were added here:
- at the perl version, the tree graph had loops, so we had to
  use BFS to traverse it. On this version, the graph is a tree,
  so, it simplifies the what group for sysfs aliases;
- the logic which splits regular expressions into subgroups
  was re-written to make it faster;
- it may optionally use multiple processes to search for symbol
  matches;
- it has some additional debug levels.

scripts/lib/abi/abi_parser.py: make it backward-compatible with Python 3.6

Despite being introduced on Python 3.6, the original implementation
was too limited: it doesn't accept anything but the argument.

Even on python 3.10.12, support was still limited, as more complex
operations cause SyntaxError:

For symbols, they need to be an exact match of what it is

scripts/get_abi.py: add a Python tool to generate ReST output

The get_abi.pl script is requiring some care, but it seems that
the number of changes on it since when I originally wrote it
was not too high.

Maintaining perl scripts without using classes requires a higher
efforted than on python, due to global variables management.
Also, it sounds easier to find python developer those days than
perl ones.

As a plus, using a Python class to handle ABI allows a better
integration with Sphinx extensions, allowing, for instance,
to let automarkup to generate cross-references for ABI
symbols.

With that in mind, rewrite the core of get_abi.pl in Python,
using classes, to help producing documentation. This will
allow a better integration in the future with the Sphinx
ABI extension.

The algorithms used there are the same as the ones in Perl,
with a couple of cleanups to remove redundant variables and
to help with cross-reference generation. While doing that,
remove some code that were important in the past, where
ABI files weren't using ReST format.

Some minor improvements were added like using a fixed seed
when generating ABI keys for duplicated names, making its
results reproductible.

The end script is a little bit faster than the original one
(tested on a machine with ssd disks). That's probably because
we're now using only pre-compiled regular expressions, and it
is using string replacement methods instead of regex where
possible.

The new version is a little bit more conservative when
converting text to cross-references to avoid adding them into
literal blocks.

To ensure that the ReST output is parsing all variables
and files properly, the end result was compared using diff
with the one produced by the perl script and showed no regressions.
There are minor improvements at the results, as it now
properly groups What on some special cases. It also better
escape some XREF names.

PM: sleep: core: Restrict power.set_active propagation

Commit 3775fc538f53 ("PM: sleep: core: Synchronize runtime PM status of
parents and children") exposed an issue related to simple_pm_bus_pm_ops
that uses pm_runtime_force_suspend() and pm_runtime_force_resume() as
bus type PM callbacks for the noirq phases of system-wide suspend and
resume.

The problem is that pm_runtime_force_suspend() does not distinguish
runtime-suspended devices from devices for which runtime PM has never
been enabled, so if it sees a device with runtime PM status set to
RPM_ACTIVE, it will assume that runtime PM is enabled for that device
and so it will attempt to suspend it with the help of its runtime PM
callbacks which may not be ready for that.  As it turns out, this
causes simple_pm_bus_runtime_suspend() to crash due to a NULL pointer
dereference.

Another problem related to the above commit and simple_pm_bus_pm_ops is
that setting runtime PM status of a device handled by the latter to
RPM_ACTIVE will actually prevent it from being resumed because
pm_runtime_force_resume() only resumes devices with runtime PM status
set to RPM_SUSPENDED.

To mitigate these issues, do not allow power.set_active to propagate
beyond the parent of the device with DPM_FLAG_SMART_SUSPEND set that
will need to be resumed, which should be a sufficient stop-gap for the
time being, but they will need to be properly addressed in the future
because in general during system-wide resume it is necessary to resume
all devices in a dependency chain in which at least one device is going
to be resumed.
