Merge tag 'kbuild-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kbuild updates from Masahiro Yamada:
- Change V=1 option to print both short log and full command log
- Allow V=1 and V=2 to be combined as V=12
- Make W=1 detect wrong .gitignore files
- Tree-wide cleanups for unused command line arguments passed to Clang
- Stop using -Qunused-arguments with Clang
- Make scripts/setlocalversion handle only correct release tags instead
of any arbitrary annotated tag
- Create Debian and RPM source packages without cleaning the source
tree
- Various cleanups for packaging
