Hi,
> Do we have any resolution of this?
I got the exact same problem if CONFIG_MODVERSIONS is enabled.
Here is my understanding.
All the symbols exported using assembler macro EXPORT_SYMBOL will need a
__crc_<symbol> to be defined later on (include/asm-generic/export.h).
This is what genksyms should do but it only runs on *.c files. So all the
symbols exported from *.S files won't get crc.
modpost is complaining about missing crc and it will not include those
symbols in *.mod.c modversion_info struct. Then, we got "Unknown
symbol" errors when modules are inserted at runtime.
I fixed it locally by setting __crc_<symbol> to a constant value in
export.h. But it may be a better idea to have genksyms run on *.S files ?
Thanks,
Mathieu
