kallsyms: ignore ARMv4 thunks along with others
lld is now able to build ARMv4 and ARMv4T kernels, which means it can generate thunks for those (__ARMv4PILongThunk_*, __ARMv4PILongBXThunk_*) that can interfere with kallsyms table generation since they do not get ignore like the corresponding ARMv5+ ones are: Inconsistent kallsyms data Try "make KALLSYMS_EXTRA_PASS=1" as a workaround Replace the hardcoded list of thunk symbols with a more general regex that covers this one along with future symbols that follow the same pattern. Fixes: 5eb6e280432d ("ARM: 9289/1: Allow pre-ARMv5 builds with ld.lld 16.0.0 and newer") Fixes: efe6e3068067 ("kallsyms: fix nonconverging kallsyms table with lld") Suggested-by: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
