# commit e6585a493921991653be1fd65c3aa3fb90b000ae
# Merge: 12c0ab6658de 7d32358be8ac
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sun Dec 6 10:31:39 2020 -0800
# 
#     Merge tag 'kbuild-fixes-v5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
#     
#     Pull Kbuild fixes from Masahiro Yamada:
#     
#      - Move -Wcast-align to W=3, which tends to be false-positive and there
#        is no tree-wide solution.
#     
#      - Pass -fmacro-prefix-map to KBUILD_CPPFLAGS because it is a
#        preprocessor option and makes sense for .S files as well.
#     
#      - Disable -gdwarf-2 for Clang's integrated assembler to avoid warnings.
#     
#      - Disable --orphan-handling=warn for LLD 10.0.1 to avoid warnings.
#     
#      - Fix undesirable line breaks in *.mod files.
