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
