Kbuild updates for v4.17
- 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 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJaw6eWAAoJED2LAQed4NsGrK8QAJmbYg83TTNoOgQRK/7Lg+sj KL1+RGFxmdHRVOqG5n18L7Q4LmTD19tUFNQImrQTTrKrbH2vbMSTF2PfzdmDRwMz R5vW5+wsagfhSttOce/GR4p9+bM9XEclzEa3liqNVQxijOFXmkV14pn0x5anYfeB ABthxFFHcVn3exP/q3lmq048x1yNE71wUU5WQIWf6V/ZKf+++wQU8r7HpnATWYeO vtf8gZq+xyLLjhxoJF6n6olSZXI7Yhz4jV2G68/VroS312AUFWPogK+cSshWGlSw zGixM1q55oj9CXjZ37nR6pTzQhSZLf/uHX5beatlpeoJ4Hho6HlIABvx2oEnat7b o5RW64RB0gVJqlYZdKxL29HNrovr9tlWPTaIPGFRvWDpl3c1w+rMKXE+5hwu8jMJ 2jgxd5FZCgBaDsAKojmeQR7PAo2ffAdUO0Dj/SuAaMOpuHWHcnJk9kIN2PUrC+Sf d/H2soT9x+60KbQmtCEo5VfEN8bvNP3+ZSnadEG/gRN2IIa5FZAUQykU+i50gAvj tuKAokdRGZHvXM+buYFBfN6RbhVCXzBF/fAG7r37QVR2u1zaUszmgFOUqERhTQfm RNnyeAs9G9rljtna/AD7cIOdKTg8oETPISxt8Y6EzNMpI8PhF0aGoxso3yD19oH1 M+fq55RigsR48Kic40hY =N5BL -----END PGP SIGNATURE----- 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 ...
