    Responding to an old post here.

    I have only recently integrated Ram's patches except for the kbuild
    integration bits. On top of this Andreas' license compatibility thing so
    in effect:
    building a GPL module (or compatible) => no change
    building a GPL-incompatible module =>
    warn if module uses EXPORT_SYMBOL_GPL_FUTURE
    error out if module uses EXPORT_SYMBOL_GPL

    Patches are in kbuild.git.
    The script to show module export statistics is not yet merged, I've
    asked Ram to fix a few things first.
