Major changes in v3: - Generate symbol CRCs as C code, and remove CONFIG_MODULE_REL_CRCS. Major changes in v2: - V1 did not work with CONFIG_MODULE_REL_CRCS. I fixed this for v2. - Reflect some review comments in v1 - Refactor the code more - Avoid too long argument error Masahiro Yamada (15): modpost: mitigate false-negatives for static EXPORT_SYMBOL checks modpost: change the license of EXPORT_SYMBOL to bool type modpost: merge add_{intree_flag,retpoline,staging_flag} to add_header modpost: move *.mod.c generation to write_mod_c_files() kbuild: generate a list of objects in vmlinux kbuild: record symbol versions in *.cmd files modpost: extract symbol versions from *.cmd files kbuild: link symbol CRCs at final link, removing CONFIG_MODULE_REL_CRCS kbuild: stop merging *.symversions genksyms: adjust the output format to modpost kbuild: do not create *.prelink.o for Clang LTO or IBT modpost: simplify the ->is_static initialization modpost: use hlist for hash table implementation kbuild: make built-in.a rule robust against too long argument error kbuild: make *.mod rule robust against too long argument error arch/powerpc/Kconfig | 1 - arch/s390/Kconfig | 1 - arch/um/Kconfig | 1 - include/asm-generic/export.h | 22 +- include/linux/export.h | 30 +-- include/linux/symversion.h | 13 + init/Kconfig | 4 - kernel/module.c | 10 +- scripts/Kbuild.include | 4 + scripts/Makefile.build | 118 +++------ scripts/Makefile.lib | 7 - scripts/Makefile.modfinal | 5 +- scripts/Makefile.modpost | 9 +- scripts/genksyms/genksyms.c | 18 +- scripts/link-vmlinux.sh | 46 ++-- scripts/mod/file2alias.c | 2 - scripts/mod/list.h | 52 ++++ scripts/mod/modpost.c | 449 ++++++++++++++++++++--------------- scripts/mod/modpost.h | 2 + 19 files changed, 402 insertions(+), 392 deletions(-) create mode 100644 include/linux/symversion.h Tested-by: Nathan Chancellor
