modpost: disallow the combination of EXPORT_SYMBOL and __meminit*
[ Upstream commit a3df1526da480c089c20868b7f4d486b9f266001 ]
Theoretically, we could export conditionally-discarded code sections,
such as .meminit*, if all the users can become modular under a certain
condition. However, that would be difficult to control and such a tricky
case has never occurred.
