The kernel-abi directive passes its argument straight to the shell.
This is unfortunate and unnecessary.
Let's always use paths relative to $srctree/Documentation/ and use
subprocess.check_call() instead of subprocess.Popen(shell=True).
This also makes the code shorter.

Add a new Sphinx extension that knows about the translations of kernel
documentation and can insert links to the translations at the top of
the document.
It basically works like this:
1. Register a new node type, LanguagesNode.
2. Register a new transform, TranslationsTransform, that inserts a new
LanguageNode at the top of every document. The LanguageNode contains
"pending references" to translations of the document. The key here
is that these are pending (i.e. unresolved) references that may or
may not actually exist.
3. Register a 'doctree-resolved' event that iterates over all the
LanguageNode nodes. Any unresolved references are filtered out; the
list of resolved references is passed to the 'translations.html'
template and rendered as an HTML node (if HTML output is selected).
Testing: make htmldocs, make latexdocs with Sphinx v4.3.2 and Firefox.
v2:
- changed bar into a drop-down menu
- fixed language labels
- fixed hysteresis reported by Akira Yokosawa

Commit 31abfdda6527 (docs: Deprecate use of Sphinx < 2.4.x) in 6.2 added a

There have been no complaints, so the time has come. Raise the minimum
Sphinx version to 2.4.4 and clean out some compatibility code that we no

Add a separate documentation directory for TEE subsystem since it is a
standalone subsystem which already offers devices consumed by multiple
different subsystem drivers.
Split overall TEE subsystem documentation modularly where:
- The userspace API has been moved to Documentation/userspace-api/tee.rst.
- The driver API has been moved to Documentation/driver-api/tee.rst.
- The first module covers the overview of TEE subsystem.
- The further modules are dedicated to different TEE implementations like:
- OP-TEE
- AMD-TEE
- and so on for future TEE implementation support.

Vegard Nossum writes:
This patch series replaces some instances of 'class:: toc-title' with
toctree's :caption: attribute, see the last patch in the series for some
more rationale/explanation.
The "toc-title" class was introduced in commit ef88f10eb877
("[media] doc-rst: backward compatibility with older Sphinx versions")
as a workaround for Sphinx versions older than 1.4.x. However, these
old versions have been deprecated since commit 31abfdda6527
("docs: Deprecate use of Sphinx < 2.4.x").
Having now changed all the toc-title users to use the :caption:
attribute, we can also remove the custom style.
Note that the toc-title class is separate from the "kernel-toc"
logic that was introduced in commit c404f5d4f099 ("docs: Add more
information to the HTML sidebar").

- Reject events meant for other PMUs in the CoreSight PMU driver,
otherwise some of the core PMU events would disappear
- Fix the Armv8 PMUv3 driver driver to not truncate 64-bit registers,
causing some events to be invisible
- Remove duplicate declaration of __arm64_sys##name following the
patch to avoid prototype warning for syscalls
- Typos in the elf_hwcap documentation"

====================
pull-request: bpf 2023-11-08
We've added 16 non-merge commits during the last 6 day(s) which contain
a total of 30 files changed, 341 insertions(+), 130 deletions(-).
The main changes are:
1) Fix a BPF verifier issue in precision tracking for BPF_ALU | BPF_TO_BE |
BPF_END where the source register was incorrectly marked as precise,
from Shung-Hsi Yu.
2) Fix a concurrency issue in bpf_timer where the former could still have
been alive after an application releases or unpins the map, from Hou Tao.
3) Fix a BPF verifier issue where immediates are incorrectly cast to u32
before being spilled and therefore losing sign information, from Hao Sun.
4) Fix a misplaced BPF_TRACE_ITER in check_css_task_iter_allowlist which
incorrectly compared bpf_prog_type with bpf_attach_type, from Chuyi Zhou.
5) Add __bpf_hook_{start,end} as well as __bpf_kfunc_{start,end}_defs macros,
migrate all BPF-related __diag callsites over to it, and add a new
__diag_ignore_all for -Wmissing-declarations to the macros to address
recent build warnings, from Dave Marchevsky.
6) Fix broken BPF selftest build of xdp_hw_metadata test on architectures
where char is not signed, from Björn Töpel.
7) Fix test_maps selftest to properly use LIBBPF_OPTS() macro to initialize
the bpf_map_create_opts, from Andrii Nakryiko.
8) Fix bpffs selftest to avoid unmounting /sys/kernel/debug as it may have
been mounted and used by other applications already, from Manu Bretelle.
