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/perf/scripts/python/mem-phys-addr.py

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

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.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.

fgraph: Fix set_graph_notrace with setting TRACE_GRAPH_NOTRACE_BIT
The code was restructured where the function graph notrace code, that
would not trace a function and all its children is done by setting a
NOTRACE flag when the function that is not to be traced is hit.
There's a TRACE_GRAPH_NOTRACE_BIT which defines the bit in the flags and a
TRACE_GRAPH_NOTRACE which is the mask with that bit set. But the
restructuring used TRACE_GRAPH_NOTRACE_BIT when it should have used
TRACE_GRAPH_NOTRACE.
For example:
# cd /sys/kernel/tracing
# echo set_track_prepare stack_trace_save > set_graph_notrace
# echo function_graph > current_tracer
# cat trace

0) | free_to_partial_list() {
0) | arch_stack_walk() {
0) | __unwind_start() {
0) 0.501 us | get_stack_info();
Where a non filter trace looks like:
# echo > set_graph_notrace
# cat trace
0) | free_to_partial_list() {
0) | set_track_prepare() {
0) | stack_trace_save() {
0) | arch_stack_walk() {
0) | __unwind_start() {
Where the filter should look like:

kbuild: Move -Wenum-enum-conversion to W=2
-Wenum-enum-conversion was strengthened in clang-19 to warn for C, which
caused the kernel to move it to W=1 in commit
75b5ab134bb5 ("kbuild:
Move -Wenum-{compare-conditional,enum-conversion} into W=1") because
there were numerous instances that would break builds with -Werror.
Unfortunately, this is not a full solution, as more and more developers,
subsystems, and distributors are building with W=1 as well, so they
continue to see the numerous instances of this warning.
Since the move to W=1, there have not been many new instances that have
appeared through various build reports and the ones that have appeared
seem to be following similar existing patterns, suggesting that most
instances of this warning will not be real issues. The only alternatives
for silencing this warning are adding casts (which is generally seen as
an ugly practice) or refactoring the enums to macro defines or a unified
enum (which may be undesirable because of type safety in other parts of
the code).
Move the warning to W=2, where warnings that occur frequently but may be
relevant should reside.
