Subject: [GIT PULL] Kbuild / Kconfig updates for 7.0
Hi Linus,
Please pull these Kbuild / Kconfig updates for 7.0. I am only aware of
one trivial conflict against the Documentation tree:
https://lore.kernel.org/aXeZT4VGXCf3a6CF@sirena.org.uk/
Please let me know if there are any issues.
Cheers,
Nathan

kbuild: remove dependency of run-command on config (2026-02-07 16:09:14 -0600)
----------------------------------------------------------------
Kbuild/Kconfig updates for 7.0
Kbuild changes
==============
* Drop '*_probe' pattern from modpost section check allowlist, which hid
legitimate warnings (Johan Hovold)
* Disable -Wtype-limits altogether, instead of enabling at W=2 (Vincent
Mailhol)
* Improve UAPI testing to skip testing headers that require a libc when
CONFIG_CC_CAN_LINK is not set, opening up testing of headers with no
libc dependencies to more environments (Thomas Weißschuh)
* Update gendwarfksyms documentation with required dependencies (Jihan
LIN)
* Reject invalid LLVM= values to avoid unintentionally falling back to
system toolchain (Thomas Weißschuh)
* Add a script to help run the kernel build process in a container for
consistent environments and testing (Guillaume Tucker)
* Simplify kallsyms by getting rid of the relative base (Ard Biesheuvel)
* Performance and usability improvements to scripts/make_fit.py (Simon
Glass)
* Minor various clean ups and fixes
Kconfig changes
===============
* Move XPM icons to individual files, clearing up GTK deprecation
warnings (Rostislav Krasny)
* Support
depends on FOO if BAR
as syntactic sugar for
depends on FOO || !BAR' (Nicolas Pitre, Graham Roff)
* Refactor merge_config.sh to use awk over shell/sed/grep, dramatically
speeding up processing large number of config fragments (Anders
Roxell, Mikko Rapeli)
