Merge tag 'kbuild-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kbuild updates from Masahiro Yamada: - add a shell script to get Clang version - improve portability of build scripts - drop always-enabled CONFIG_THIN_ARCHIVE and remove unused code - rename built-in.o which is now thin archive to built-in.a - process clean/build targets one by one to get along with -j option - simplify ld-option - improve building with CONFIG_TRIM_UNUSED_KSYMS - define KBUILD_MODNAME even for objects shared among multiple modules - avoid linking multiple instances of same objects from composite objects - move <linux/compiler_types.h> to c_flags to include it only for C files - clean-up various Makefiles * tag 'kbuild-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (29 commits) kbuild: get <linux/compiler_types.h> out of <linux/kconfig.h> kbuild: clean up link rule of composite modules kbuild: clean up archive rule of built-in.a kbuild: remove partial section mismatch detection for built-in.a net: liquidio: clean up Makefile for simpler composite object handling lib: zstd: clean up Makefile for simpler composite object handling kbuild: link $(real-obj-y) instead of $(obj-y) into built-in.a kbuild: rename real-objs-y/m to real-obj-y/m kbuild: move modname and modname-multi close to modname_flags kbuild: simplify modname calculation kbuild: fix modname for composite modules kbuild: define KBUILD_MODNAME even if multiple modules share objects kbuild: remove unnecessary $(subst $(obj)/, , ...) in modname-multi kbuild: Use ls(1) instead of stat(1) to obtain file size kbuild: link vmlinux only once for CONFIG_TRIM_UNUSED_KSYMS kbuild: move include/config/ksym/* to include/ksym/* kbuild: move CONFIG_TRIM_UNUSED_KSYMS code unneeded for external module kbuild: restore autoksyms.h touch to the top Makefile kbuild: move 'scripts' target below kbuild: remove wrong 'touch' in adjust_autoksyms.sh ...

the analysis would not catch the illegal reference.
This option tells gcc to inline less (but it does result in
a larger kernel).

+ - Run the section mismatch analysis for each module/built-in.a file.
When we run the section mismatch analysis on vmlinux.o, we
lose valuable information about where the mismatch was
introduced.

+ Running the analysis for each module/built-in.a file
tells where the mismatch happens much closer to the
source. The drawback is that the same mismatch is
reported at least twice.
