When did you last try? I usually send patches whenever I see a new
warning, so there really shouldn't be any such warnings in the mainline
kernel except for cases where patches are still under discussion.

If you have a configuration in which you see lots of frame size warnings,
can you send me that .config file for that? It is possible that one or
more of the patches in my backlog fix a bunch of those issues
and need to be resent.
