Subject: [PATCH v3 00/15] kbuild: yet another series of cleanups (modpost, LTO, MODULE_REL_CRCS)
Date: Thu, 5 May 2022 16:22:29 +0900 [thread overview]
Message-ID: <20220505072244.1155033-1-masahiroy@kernel.org> (raw)
This is the third batch of cleanups in this development cycle.
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
