Subject: [PATCH 128/147] module: Remove module size limit

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.
