docs: process: remove outdated submitting-drivers.rst
Commit
31b24bee3357 ("docs: add a warning to submitting-drivers.rst")
in October 2016 already warns "This (...) should maybe just be deleted,
but I'm not quite ready to do that yet".
Maybe, six years ago, we were not ready but let us remove old content
for the better now and structure and maintain less content in the kernel
documentation with a better result.
Drop this already outdated document and adjust all textual references.
Here is an argument why deleting the content will not remove any useful
information to the existing kernel documentation, individually broken down
for each section.
Section "Allocating Device Numbers" refers to https://www.lanana.org/, and
then refers to Documentation/admin-guide/devices.rst.
However, the devices.rst clearly states:
"The version of this document at lanana.org is no longer maintained."
Everything needed for submitting drivers is already stated in devices.rst
and the reference to https://www.lanana.org/ is outdated, and should be
just deleted.
Section "Who To Submit Drivers To" is all about Linux 2.0 - 2.6, before
the new release version scheme; the mentioned developers are still around,
but actually not the first developers to contact anymore.
Section "What Criteria Determine Acceptance" has a few bullet points:
Licensing and Copyright is well-covered in process/kernel-license.rst.
Interfaces, Code, Portability, Clarity state some obvious things about
ensuring kernel code quality.
Control suggests to add a MAINTAINERS entry, which is already mentioned in
6.Followthrough.rst: "... added yourself to the MAINTAINERS file..."
PM support states a bit about implementing and testing power management of
a driver, it remains an open question where to place that in the process
documents. Driver developers interested in power management will find the
corresponding part on power management in the kernel documentation anyway.
In section "What Criteria Do Not Determine Acceptance", the points Vendor
and Author states something basic consequence of the kernel being an
open-source community software development. Probably no need to mention it
nowadays.
Section "Resources" lists resources that are also mentioned elsewhere more
central.

docs: admin: devices: drop confusing outdated statement on Latex
The statement that the Latex version of Linux Device List is unmaintained,
must go back to some historic time where there were actually two separate
document sources, one in a txt format and another in a tex format (maybe
even just on lanana.org).
Nowadays, html and tex are generated from the ReST document file and the
statement might be confused, believing the actual generated LaTeX document
from the maintained ReST document could be an unmaintained one.
Remove this statement on the LaTeX version and only keep pointing out that
the version on lanana.org is no longer maintained.

docs: automarkup: do not look up symbols twice
The automarkup code tries to look up symbols once as a function, and once
as a macro. The Sphinx C domain code, though, totally ignores that
distinction and will return the same results either way. So just look
things up once and be done with it; the resulting output does not change,

The automarkup code tries to create a lot of cross-references that don't

scripts: kernel-doc: Always increment warnings counter
Some warnings do not increment the warnings counter making the behavior
of running kernel-doc with -Werror unlogical as some warnings will be
generated but not treated as errors.
Fix this by creating a helper function that always incrementing the
warnings counter every time a warning is emitted. There is one location
in get_sphinx_version() where a warning is not touched as it concerns
the execution environment of the kernel-doc and not the documentation
being processed.
Incrementing the counter only have effect when running kernel-doc in
either verbose mode (-v or environment variable KBUILD_VERBOSE) or when
treating warnings as errors (-Werror or environment variable
KDOC_WERROR). In both cases the number of warnings printed is printed to
stderr and for the later the exit code of kernel-doc is non-zero if
warnings where encountered.
Simple test case to demo one of the warnings,
$ cat test.c
/**
* foo() - Description
*/
int bar();
# Without this change
$ ./scripts/kernel-doc -Werror -none test.c
test.c:4: warning: expecting prototype for foo(). Prototype was for
bar() instead

Pull random number generator fixes from Jason Donenfeld:
- A fix for a 5.19 regression for a case in which early device tree
initializes the RNG, which flips a static branch.
On most plaforms, jump labels aren't initialized until much later, so
this caused splats. On a few mailing list threads, we cooked up easy
fixes for arm64, arm32, and risc-v. But then things looked slightly
more involved for xtensa, powerpc, arc, and mips. And at that point,
when we're patching 7 architectures in a place before the console is
even available, it seems like the cost/risk just wasn't worth it.
So random.c works around it now by checking the already exported
`static_key_initialized` boolean, as though somebody already ran into
this issue in the past. I'm not super jazzed about that; it'd be
prettier to not have to complicate downstream code. But I suppose
it's practical.
- A few small code nits and adding a missing __init annotation.
- A change to the default config values to use the cpu and bootloader's
seeds for initializing the RNG earlier.
This brings them into line with what all the distros do (Fedora/RHEL,
Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at
least), and moreover will now give us test coverage in various test
beds that might have caught the above device tree bug earlier.
- A change to WireGuard CI's configuration to increase test coverage
around the RNG.
- A documentation comment fix to unrelated maintainerless CRC code that
I was asked to take, I guess because it has to do with polynomials
(which the RNG thankfully no longer uses).

(

The original code created a buffer size of 128 bytes regardless if
the WMI call required a smaller buffer or not. This particular
behavior occurs in older BIOS and reproduced in OMEN laptops. Newer
BIOS handles buffer sizes properly and meets the latest specification
requirements. This is the reason why testing with a dynamically
allocated buffer did not uncover any failures with the test systems at
hand.
This patch was tested on several OMEN, Elite, and Zbooks. It was
confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN
Laptop 15-ek0xxx. No problems were reported when testing on several Elite
and Zbooks notebooks.

iov_iter: fix build issue due to possible type mis-match
Commit
6c77676645ad ("iov_iter: Fix iter_xarray_get_pages{,_alloc}()")
introduced a problem on some 32-bit architectures (at least arm, xtensa,
csky,sparc and mips), that have a 'size_t' that is 'unsigned int'.
The reason is that we now do
min(nr * PAGE_SIZE - offset, maxsize);
where 'nr' and 'offset' and both 'unsigned int', and PAGE_SIZE is
'unsigned long'. As a result, the normal C type rules means that the
first argument to 'min()' ends up being 'unsigned long'.
In contrast, 'maxsize' is of type 'size_t'.
Now, 'size_t' and 'unsigned long' are always the same physical type in
the kernel, so you'd think this doesn't matter, and from an actual
arithmetic standpoint it doesn't.
But on 32-bit architectures 'size_t' is commonly 'unsigned int', even if
it could also be 'unsigned long'. In that situation, both are unsigned
32-bit types, but they are not the *same* type.
And as a result 'min()' will complain about the distinct types (ignore
the "pointer types" part of the error message: that's an artifact of the
way we have made 'min()' check types for being the same):
lib/iov_iter.c: In function 'iter_xarray_get_pages':
include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror]
20 | (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1)))
| ^~
lib/iov_iter.c:1464:16: note: in expansion of macro 'min'
1464 | return min(nr * PAGE_SIZE - offset, maxsize);
| ^~~
This was not visible on 64-bit architectures (where we always define
'size_t' to be 'unsigned long').
Force these cases to use 'min_t(size_t, x, y)' to make the type explicit
and avoid the issue.
[ Nit-picky note: technically 'size_t' doesn't have to match 'unsigned
long' arithmetically. We've certainly historically seen environments
with 16-bit address spaces and 32-bit 'unsigned long'.
Similarly, even in 64-bit modern environments, 'size_t' could be its
own type distinct from 'unsigned long', even if it were arithmetically
identical.
So the above type commentary is only really descriptive of the kernel
environment, not some kind of universal truth for the kinds of wild
and crazy situations that are allowed by the C standard ]

wireguard: selftests: use maximum cpu features and allow rng seeding
By forcing the maximum CPU that QEMU has available, we expose additional
capabilities, such as the RNDR instruction, which increases test
coverage. This then allows the CI to skip the fake seeding step in some
cases. Also enable STRICT_KERNEL_RWX to catch issues related to early
jump labels when the RNG is initialized at boot.
