| |
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sasha Levin <levinsasha928@gmail.com>
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.
