This patch set refactors EXPORT_SYMBOL, <linux/export.h> and <asm/export.h>. Also, re-implement TRIM_UNUSED_KSYMS in one-pass. You can still put EXPORT_SYMBOL() in *.S file, very close to the definition, but you do not need to care about whether it is a function or a data. Remove EXPORT_DATA_SYMBOL(). In v1, I broke ia64 because of missing distinction between functions and data. V2 handles it correctly. If the exported symbols is a function, KSYMTAB_FUNC is output. Otherwise, KSYMTAB_DATA is output. Masahiro Yamada (7): kbuild: generate KSYMTAB entries by modpost ia64,export.h: replace EXPORT_DATA_SYMBOL* with EXPORT_SYMBOL* modpost: merge sym_update_namespace() into sym_add_exported() modpost: use null string instead of NULL pointer for default namespace modpost: squash report_sec_mismatch() and remove enum mismatch kbuild: implement CONFIG_TRIM_UNUSED_KSYMS without recursion kbuild: move modules.builtin(.modinfo) rules to Makefile.vmlinux_o .gitignore | 1 - Makefile | 24 +--- arch/ia64/include/asm/Kbuild | 1 + arch/ia64/include/asm/export.h | 3 - arch/ia64/kernel/head.S | 2 +- arch/ia64/kernel/ivt.S | 2 +- include/asm-generic/export.h | 83 +----------- include/linux/export-internal.h | 67 +++++++++- include/linux/export.h | 114 +++------------- kernel/module/internal.h | 1 + kernel/module/main.c | 1 - scripts/Makefile.build | 15 +-- scripts/Makefile.modpost | 8 +- scripts/Makefile.vmlinux_o | 26 +++- scripts/adjust_autoksyms.sh | 73 ---------- scripts/basic/fixdep.c | 3 +- scripts/check-local-export | 4 +- scripts/gen_autoksyms.sh | 62 --------- scripts/gen_ksymdeps.sh | 30 ----- scripts/link-vmlinux.sh | 12 +- scripts/mod/modpost.c | 228 ++++++++++++++++---------------- scripts/mod/modpost.h | 1 + scripts/remove-stale-files | 2 + 23 files changed, 258 insertions(+), 505 deletions(-) delete mode 100644 arch/ia64/include/asm/export.h delete mode 100755 scripts/adjust_autoksyms.sh delete mode 100755 scripts/gen_autoksyms.sh delete mode 100755 scripts/gen_ksymdeps.sh -- 2.34.1
