Merge tag 'kbuild-7.0-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kbuild/linux

Pull Kbuild/Kconfig updates from Nathan Chancellor:
 "Kbuild:

   - 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:

   - 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)"
