The problem with that is that it is so configuration dependent.
Also there are occasional cases where we add exports in one merge window
for the users to appear in the next one to reduce cross-subsystem
dependencies, so we'd nee to do this manually.
Maybe just having CONFIG_TRIM_UNUSED_KSYMS outout the unused symbols
in a log file and manually looking over that for various allmodconfigs
might be a good start.
