Please go and discuss estoppel, wilful infringement and re-licensing with your corporate attorneys. If you want to relicense components of the code then please take the matter up with the corporate attorneys of the rights holders concerned.
Alan please stick with the facts. This isn't a relicense of anything. EXPORT_SYMBOL_GPL isn't a license its nothing like a license. Its a totally pointless thing, it should be EXPORT_SYMBOL_USERS_MIGHT_BE_DERIVED_CONSULT_YOUR_LAWYER, but it really should be EXPORT_SYMBOL, and really consult your lawyers anyways.
Also we should look at this http://lists.linaro.org/pipermail/linaro-mm-sig/2011-September/000616.html
original code posting had no EXPORT_SYMBOL, so the original author's intents were quite clear.
Dave.
