#     Merge tag 'kbuild-v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
#     
#     Pull Kbuild updates from Masahiro Yamada:
#     
#      - Support cross-compiling linux-headers Debian package and kernel-devel
#        RPM package
#     
#      - Add support for the linux-debug Pacman package
#     
#      - Improve module rebuilding speed by factoring out the common code to
#        scripts/module-common.c
#     
#      - Separate device tree build rules into scripts/Makefile.dtbs
#     
#      - Add a new script to generate modules.builtin.ranges, which is useful
#        for tracing tools to find symbols in built-in modules
#     
#      - Refactor Kconfig and misc tools
#     
#      - Update Kbuild and Kconfig documentation
#
