MIPS supports PC32 relocations like most other architectures, which will
be used by kallsyms to make its symbol references visible to the linker.
Given that these are place-relative, they can be ignored by the 'relocs'
tool, just like other PC type relocations.

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.

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
execution on hexagon so far.
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.

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.

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.

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/.

xpm_menu_inv and xpm_void were removed and not converted into xpm files

[nathan: Minor commit message clean ups]
Signed-off-by: Nathan Chancellor <nathan@kernel.org>
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.

Initializing automatic __free variables to NULL without need (e.g.
branches with different allocations), followed by actual allocation is
in contrary to explicit coding rules guiding cleanup.h:
"Given that the "__free(...) = NULL" pattern for variables defined at
the top of the function poses this potential interdependency problem the
recommendation is to always define and assign variables in one statement
and not group variable definitions at the top of the function when
__free() is used."
Code does not have a bug, but is less readable and uses discouraged
coding practice, so fix that by moving declaration to the place of
assignment.

Not that other existing usage of __free() in this context is a corret
exception initialized to NULL, because the actual allocation is branched
in if().

Pull LoongArch updates from Huacai Chen:
- Add basic LoongArch32 support
Note: Build infrastructures of LoongArch32 are not enabled yet,
because we need to adjust irqchip drivers and wait for GNU toolchain
be upstream first.
- Select HAVE_ARCH_BITREVERSE in Kconfig
- Fix build and boot for CONFIG_RANDSTRUCT
- Correct the calculation logic of thread_count
- Some bug fixes and other small changes
