smbfs-related panic

[Julio Merino <jmmv84%gmail.com@localhost>]

Hello,

With an amd64 current built today, I get the following panic with
mount -t smbfs:

# mount -t smbfs -o ro,-N,-Imini.julipedia.org //jmmv@mini/shared /shared
fatal page fault in supervisor mode

rump_smbfs crashes instead, so I should have imagined the panic coming.

Any ideas?
