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.

The ABI documentation looks a little bit better if it starts
with the contents of the README is placed at the beginning.
Move it to the beginning of the ABI chapter. While here, improve
the README text and change the title that will be shown at the
html/pdf output to be coherent with both ABI file contents and
with the generated documentation output.

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.

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.

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:

Now that all ABI files are handled together, we can add a feature
at automarkup for it to generate cross-references for ABI symbols.
The cross-reference logic can produce references for all existing
files, except for README (as this is not parsed).
For symbols, they need to be an exact match of what it is
described at the docs, which is not always true due to wildcards.
If symbols at /sys /proc and /config are identical, a cross-reference
will be used.

Right now, the logic parses ABI files on 4 steps, one for each
directory. While this is fine in principle, by doing that, not
all symbol cross-references will be created.
Change the logic to do the parsing only once in order to get
a global dictionary to be used when creating ABI cross-references.

in separate. As an additional benefit, there's no need to place

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.

Such scripts may have regular expressions, which would make the

-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.

When using Rust on the x86 architecture, we are currently using the
unstable target.json feature to specify the compilation target. Rustc is
going to change how softfloat is specified in the target.json file on
x86, thus update generate_rust_target.rs to specify softfloat using the
new option.
Note that if you enable this parameter with a compiler that does not
recognize it, then that triggers a warning but it does not break the
build.
[ For future reference, this solves the following error:

Linus observed that the symbol_request(utf8_data_table) call fails when
CONFIG_UNICODE=y and CONFIG_TRIM_UNUSED_KSYMS=y.
symbol_get() relies on the symbol data being present in the ksymtab for
symbol lookups. However, EXPORT_SYMBOL_GPL(utf8_data_table) is dropped
due to CONFIG_TRIM_UNUSED_KSYMS, as no module references it in this case.
Probably, this has been broken since commit dbacb0ef670d ("kconfig option
for TRIM_UNUSED_KSYMS").
This commit addresses the issue by leveraging modpost. Symbol names
passed to symbol_get() are recorded in the special .no_trim_symbol
section, which is then parsed by modpost to forcibly keep such symbols.
The .no_trim_symbol section is discarded by the linker scripts, so there
is no impact on the size of the final vmlinux or modules.
This commit cannot resolve the issue for direct calls to __symbol_get()
because the symbol name is not known at compile-time.
Although symbol_get() may eventually be deprecated, this workaround
should be good enough meanwhile.

Clang's -Wformat-overflow and -Wformat-truncation have chosen to check
'%p' unlike GCC but it does not know about the kernel's pointer
extensions in lib/vsprintf.c, so the developers split that part of the
warning out for the kernel to disable because there will always be false
positives.
Commit 908dd508276d ("kbuild: enable -Wformat-truncation on clang") did
disabled these warnings but only in a block that would be called when
W=1 was not passed, so they would appear with W=1. Move the disabling of
the non-kprintf warnings to a block that always runs so that they are
never seen, regardless of warning level.

Since commit bede169618c6 ("kbuild: enable objtool for *.mod.o and
additional kernel objects"), Clang LTO builds do not perform any
optimizations when CONFIG_OBJTOOL is disabled (e.g., for ARCH=arm64).
This is because every LLVM bitcode file is immediately converted to
ELF format before the object files are linked together.
This commit fixes the breakage.

Due to the fact that runtime const ELF sections are named without a
leading period or double underscore, the RSTRIP logic that removes the
static RELA sections from vmlinux fails to identify them. This results
in a situation like below, where some sections that were supposed to get
removed are left behind.
[Nr] Name Type Address Off Size ES Flg Lk Inf Al
[58] runtime_shift_d_hash_shift PROGBITS ffffffff83500f50 2900f50 000014 00 A 0 0 1

So tweak the match expression to strip all sections starting with .rel.
While at it, consolidate the logic used by RISC-V, s390 and x86 into a
single shared Makefile library command.

GCC 15 introduces a regression in "= { 0 }" style initialization of
unions that Linux has depended on for eliminating uninitialized variable
contents. GCC does not seem likely to fix it[1], instead suggesting[2]
that affected projects start using -fzero-init-padding-bits=unions.
To avoid future surprises beyond just the current situation with unions,
enable -fzero-init-padding-bits=all when available (GCC 15+). This will
correctly zero padding bits in unions and structs that might have been
left uninitialized, and will make sure there is no immediate regression
in union initializations. As seen in the stackinit KUnit selftest union
cases, which were passing before, were failing under GCC 15:
not ok 18 test_small_start_old_zero
ok 29 test_small_start_dynamic_partial # SKIP XFAIL uninit bytes: 63
ok 32 test_small_start_assigned_dynamic_partial # SKIP XFAIL uninit bytes: 63
ok 67 test_small_start_static_partial # SKIP XFAIL uninit bytes: 63
ok 70 test_small_start_static_all # SKIP XFAIL uninit bytes: 56
ok 73 test_small_start_dynamic_all # SKIP XFAIL uninit bytes: 56
ok 82 test_small_start_assigned_static_partial # SKIP XFAIL uninit bytes: 63
ok 85 test_small_start_assigned_static_all # SKIP XFAIL uninit bytes: 56
ok 88 test_small_start_assigned_dynamic_all # SKIP XFAIL uninit bytes: 56
The above all now pass again with -fzero-init-padding-bits=all added.
This also fixes the following cases for struct initialization that had
been XFAIL until now because there was no compiler support beyond the
larger "-ftrivial-auto-var-init=zero" option:
ok 38 test_small_hole_static_all # SKIP XFAIL uninit bytes: 3
ok 39 test_big_hole_static_all # SKIP XFAIL uninit bytes: 124
ok 40 test_trailing_hole_static_all # SKIP XFAIL uninit bytes: 7
ok 42 test_small_hole_dynamic_all # SKIP XFAIL uninit bytes: 3
ok 43 test_big_hole_dynamic_all # SKIP XFAIL uninit bytes: 124
ok 44 test_trailing_hole_dynamic_all # SKIP XFAIL uninit bytes: 7
ok 58 test_small_hole_assigned_static_all # SKIP XFAIL uninit bytes: 3
ok 59 test_big_hole_assigned_static_all # SKIP XFAIL uninit bytes: 124
ok 60 test_trailing_hole_assigned_static_all # SKIP XFAIL uninit bytes: 7
ok 62 test_small_hole_assigned_dynamic_all # SKIP XFAIL uninit bytes: 3
ok 63 test_big_hole_assigned_dynamic_all # SKIP XFAIL uninit bytes: 124
ok 64 test_trailing_hole_assigned_dynamic_all # SKIP XFAIL uninit bytes: 7
All of the above now pass when built under GCC 15. Tests can be seen
with:
./tools/testing/kunit/kunit.py run stackinit --arch=x86_64 \
--make_option CC=gcc-15
Clang continues to fully initialize these kinds of variables[3] without
additional flags.

Most 'make *config' commands use .config as the base configuration file.
When .config does not exist, Kconfig tries to load a file listed in
KCONFIG_DEFCONFIG_LIST instead.
However, since commit b75b0a819af9 ("kconfig: change defconfig_list
option to environment variable"), warning messages have displayed an
incorrect file name in such cases.
Below is a demonstration using Debian Trixie. While loading
/boot/config-6.12.9-amd64, the warning messages incorrectly show .config
as the file name.
With this commit, the correct file name is displayed in warnings.
[Before]
$ rm -f .config

A longstanding issue with genksyms is that it has hidden syntax errors.
For example, genksyms fails to parse the following valid code:
int x, __attribute__((__section__(".init.data")))y;
Here, only 'y' is annotated by the attribute, although I am not aware
of actual uses of this pattern in the kernel tree.
When a syntax error occurs, yyerror() is called. However,
error_with_pos() is a no-op unless the -w option is provided.
You can observe syntax errors by manually passing the -w option.
$ echo 'int x, __attribute__((__section__(".init.data")))y;' | scripts/genksyms/genksyms -w
<stdin>:1: syntax error
This commit allows attributes to be placed between a comma and
init_declarator.

The deprecated_apis map was created in [1] so checkpatch would flag
deprecated RCU APIs. These deprecated APIs have since been removed from
the kernel. This patch removes them from this map so checkpatch doesn't
waste time looking for them, and so readers of checkpatch looking for
deprecated APIs don't waste time searching for them.
