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
