3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Sasha Levin <[email protected]> commit f946eeb9313ff1470758e171a60fe7438a2ded3f upstream. Module size was limited to 64MB, this was legacy limitation due to vmalloc() which was removed a while ago. Limiting module size to 64MB is both pointless and affects real world use cases.
