Merge tag 'kbuild-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kbuild updates from Masahiro Yamada:
- Make Kconfig parse the input .config more precisely
- Support W=c and W=e options for Kconfig
- Set Kconfig int/hex symbols to zero if the 'default' property is
missing
- Add .editorconfig
- Add scripts/git.orderFile
- Add a script to detect backward-incompatible changes in UAPI headers
- Resolve the symlink passed to O= option properly
- Use the user-supplied mtime for all files in the builtin initramfs,
which provides better reproducible builds
- Fix the direct execution of debian/rules for Debian package builds
- Use build ID instead of the .gnu_debuglink section for the Debian dbg
package
