Major changes in v4: - Move static EXPORT_SYMBOL check to a script - Some refactoring 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 (14): modpost: remove left-over cross_compile declaration modpost: change the license of EXPORT_SYMBOL to bool type modpost: split the section mismatch checks into section-check.c modpost: add sym_find_with_module() helper 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 kbuild: check static EXPORT_SYMBOL* by script instead of modpost kbuild: make built-in.a rule robust against too long argument error kbuild: make *.mod rule robust against too long argument error kbuild: add cmd_and_savecmd macro kbuild: rebuild multi-object modules when objtool is updated arch/powerpc/Kconfig | 1 - arch/s390/Kconfig | 1 - arch/um/Kconfig | 1 - include/asm-generic/export.h | 22 +- include/linux/export-internal.h | 16 + include/linux/export.h | 30 +- init/Kconfig | 4 - kernel/module.c | 10 +- scripts/Kbuild.include | 10 +- scripts/Makefile.build | 134 +-- scripts/Makefile.lib | 7 - scripts/Makefile.modfinal | 5 +- scripts/Makefile.modpost | 9 +- scripts/check-local-export | 48 + scripts/genksyms/genksyms.c | 18 +- scripts/link-vmlinux.sh | 33 +- scripts/mod/Makefile | 2 +- scripts/mod/modpost.c | 1499 ++++--------------------------- scripts/mod/modpost.h | 35 +- scripts/mod/section-check.c | 1222 +++++++++++++++++++++++++ 20 files changed, 1551 insertions(+), 1556 deletions(-) create mode 100644 include/linux/export-internal.h create mode 100755 scripts/check-local-export create mode 100644 scripts/mod/section-check.c -- 2.32.0
