#     Merge tag 'kbuild-fixes-v5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
#     
#     Pull Kbuild fixes from Masahiro Yamada:
#     
#      - Remove harmful -Oz option of Clang
#     
#      - Get back the original behavior (no recursion for in-tree build) for
#        GNU Make 4.x
#     
#      - Some minor fixes for coccinelle patches
#     
#      - Do not overwrite .gitignore in the output directory in case it is
#        version-controlled
#     
#      - Fix missed record-mcount bug for dynamic ftrace
#     
#      - Fix endianness bug in modversions for relative CRC
#     
#      - Cater to '^H' key code in Kconfig ncurses programs
#
