#     Merge tag 'kbuild-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
#     
#     Pull Kbuild updates from Masahiro Yamada:
#     
#      - run the checker (e.g. sparse) after the compiler
#     
#      - remove unneeded cc-option tests for old compiler flags
#     
#      - fix tar-pkg to install dtbs
#     
#      - introduce ccflags-remove-y and asflags-remove-y syntax
#     
#      - allow to trace functions in sub-directories of lib/
#     
#      - introduce hostprogs-always-y and userprogs-always-y syntax
#     
#      - various Makefile cleanups
#     
#     * tag 'kbuild-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
#       kbuild: stop filtering out $(GCC_PLUGINS_CFLAGS) from cc-option base
