Subject: linux-next: build failure after merge of the userns tree

Hi all,
After merging the userns tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
ERROR: modpost: ".do_exit" [drivers/vhost/vhost.ko] undefined!
Caused by commit
eb55e716ac1a ("exit: Stop exporting do_exit")
interacting with commit
bbf761db7dbb ("vhost: use user_worker to check RLIMITs")
from the vhost tree.
I have added the following merge fix patch.

This lead to:

so I added the following as well.
