f2445d6f26 rust: kconfig: Don't require RUST_IS_AVAILABLE for rustc-option
The final version of this macro does not fail in the absence of an
invokable `$(RUSTC)`, so we don't need to be careful not to invoke it.

5fa9b82cbc scripts: kconfig: merge_config.sh: refactor from shell/sed/grep to awk
merge_config.sh shell/sed/grep loop scales poorly and is slow.
With Yocto genericarm64 kernel and around 190 config fragments
the script takes more than 20 minutes to run on a fast build machine.
Re-implementation with awk does the same job in 10 seconds.
Using awk since it is likely available in the build environments
and using perl, python etc would introduce more complex runtime
dependencies. awk is good enough and lot better than shell/sed/grep.

Output stays the same but changed execution time means that
parallel job output may be ordered differently.

a081b57892 kallsyms: Get rid of kallsyms relative base
When the kallsyms relative base was introduced, per-CPU variable
references on x86_64 SMP were implemented as offsets into the respective
per-CPU region, rather than offsets relative to the location of the
variable's template in the kernel image, which is how other
architectures implement it.

This required kallsyms to reason about the difference between the two,
and the sign of the value in the kallsyms_offsets[] array was used to
distinguish them. This meant that negative offsets were not permitted
for ordinary variables, and so it was crucial that the relative base was
chosen such that all offsets were positive numbers.

This is no longer needed: instead, the offsets can simply be encoded as
values in the range -/+ 2 GiB, which is precisely what PC32 relocations
provide on most architectures. So it is possible to simplify the logic,
and just use _text as the anchor directly, and let the linker calculate
the final value based on the location of the entry itself.

Some architectures (nios2, extensa) do not support place-relative
relocations at all, but these are all 32-bit and non-relocatable, and so
there is no need for place-relative relocations in the first place, and
the actual symbol values can just be stored directly.

This makes all entries in the kallsyms_offsets[] array visible as
place-relative references in the ELF metadata, which will be important
when implementing ELF-based fg-kaslr.

502678b88c kbuild: Reject unexpected values for LLVM=
The LLVM argument is documented to accept one of three forms:
* a literal '1' to use the default 'clang',
* a toolchain prefix path, ending in a trailing '/',
* a version suffix.

All other values are silently treated as '1'. If for example
the user accidentally forgets the trailing '/' of a toolchain prefix,
kbuild will unexpectedly and silently fall back to the system toolchain.

Instead report an error if the user specified an invalid value for LLVM.

2a0a30805a kbuild: uapi: drop dependency on CC_CAN_LINK
The header tests try to compile each header. Some UAPI headers depend on
libc headers so they need a full userspace toolchain to build. This
dependency is expressed in kconfig as a dependency on CC_CAN_LINK.
Many kernel builds do not satisfy CC_CAN_LINK as they only use a
minimal kernel (cross-) compiler. In those configurations the UAPI
headers are not tested at all.

However most UAPI headers do not even depend on any libc headers,
and such dependencies are undesired in any case. Also the static
analysis performed by headers_check.pl does not need CC_CAN_LINK.

Drop the hard dependency on CC_CAN_LINK and instead skip the affected
compilation step for exactly those headers which require libc.

This UAPI header contains declarations of internal kernel symbols.
Such declarations are invalid. Normally headers_check.pl would report
an error, but apparently its dependency on CC_CAN_LINK prevent its

As the header does not expose any additional UAPI, just make it a
regular internal kernel header. asm-generic/signal.h will be used
for the UAPI automatically, the same as before.

76df6815da kconfig: Support conditional deps using "depends on X if Y"
Extend the "depends on" syntax to support conditional dependencies
using "depends on X if Y". While functionally equivalent to "depends
on X || (Y == n)", "depends on X if Y" is much more readable and
makes the kconfig language uniform in supporting the "if <expr>"
suffix.
This also improves readability for "optional" dependencies, which
are the subset of conditional dependencies where X is Y.
Previously such optional dependencies had to be expressed as
the counterintuitive "depends on X || !X", now this can be
represented as "depends on X if X".

The change is implemented by converting the "X if Y" syntax into the
"X || (Y == n)" syntax during "depends on" token processing.

this warning is disabled, those two macros have lost their raison
d'être. Remove them.

This reverts commit dc7fe518b0 ("overflow: Fix -Wtype-limits
compilation warnings").

660e899103 kbuild: remove gcc's -Wtype-limits
W=2 builds are heavily polluted by the -Wtype-limits warning.

Here are some W=12 statistics on Linux v6.19-rc1 for an x86_64
defconfig (with just CONFIG_WERROR set to "n") using gcc 14.3.1:

	 Warning name			count	percent
	-------------------------------------------------
	 -Wlogical-op			    2	  0.00 %
	 -Wmaybe-uninitialized		  138	  0.20 %
	 -Wunused-macros		  869	  1.24 %
	 -Wmissing-field-initializers	 1418	  2.02 %
	 -Wshadow			 2234	  3.19 %
	 -Wtype-limits			65378	 93.35 %
	-------------------------------------------------
	 Total				70039	100.00 %

As we can see, -Wtype-limits represents the vast majority of all
warnings. The reason behind this is that these warnings appear in
some common header files, meaning that some unique warnings are
repeated tens of thousands of times (once per header inclusion).

Add to this the fact that each warning is coupled with a dozen lines
detailing some macro expansion. The end result is that the W=2 output
is just too bloated and painful to use.

Three years ago, I proposed in [1] modifying one such header to
silence that noise. Because the code was not faulty, Linus rejected
the idea and instead suggested simply removing that warning.

At that time, I could not bring myself to send such a patch because,
despite its problems, -Wtype-limits would still catch the below bug:

	unsigned int ret;

	ret = check();
	if (ret < 0)
		error();

Meanwhile, based on another suggestion from Linus, I added a new check
to sparse [2] that would catch the above bug without the useless spam.

With this, remove gcc's -Wtype-limits. People who still want to catch
incorrect comparisons between unsigned integers and zero can now use
sparse instead.

On a side note, clang also has a -Wtype-limits warning but:

  * it is not enabled in the kernel at the moment because, contrary to
    gcc, clang did not include it under -Wextra.

  * it does not warn if the code results from a macro expansion. So,
    if activated, it would not cause as much spam as gcc does.

  * -Wtype-limits is split into four sub-warnings [3] meaning that if
    it were to be activated, we could select which one to keep.

So there is no present need to explicitly disable -Wtype-limits in
clang.

f8e05c1063 kbuild: Add top-level target for building gen_init_cpio
Add a top-level target for building gen_init_cpio to prevent re-entering
kbuild for 'modules-cpio-pkg'.

The recently introduced target 'modules-cpio-pkg' depends on
gen_init_cpio but there is no simple way to add this dependency as a
prerequisite that can be built in parallel to other recipes.

Introducing the top-level target, enables fixing this and also prepares
a possible move of gen_init_cpio from usr/ to scripts/.

18e2d526bf kconfig: move XPM icons to separate files
Replace deprecated gdk_pixbuf_new_from_xpm_data() with gdk_pixbuf_new_from_file()
and update both GTK and QT frontends to load XPM icons from separate files
in scripts/kconfig/icons/ instead of from the code.

xpm_menu_inv and xpm_void were removed and not converted into xpm files
because they are not used since commit 64285dc5c4 ("kconfig: gconf:
inline fill_row() into set_node()").

This eliminates the GTK deprecation warnings at compile time and
improves memory usage and code organization.

a4df2071f1 modpost: drop '*_probe' from section check whitelist
Several symbol patterns used to be whitelisted to allow drivers to refer
to functions annotated with __devinit and __devexit, which have since
been removed.

Commit e1dc1bfe5b ("modpost: remove more symbol patterns from the
section check whitelist") removed most of these patterns but left
'*_probe' after a reported warning in an irqchip driver.

Turns out that was indeed an incorrect reference which has now been
fixed by commit 9b685058ca ("irqchip/qcom-irq-combiner: Fix section
mismatch").

A recently added clocksource driver also relies on this suffix to
suppress another valid warning, and that is being fixed separately. [1]

Note that drivers with valid reasons for suppressing the warnings can
use the __ref macros.
