The commit below was backported as part of the recent stable
update.  Part of that backport incorrectly introduced use of a newer
interface into the ip6_tunnel driver leading to crashes when this tunnel
type is brought up:

    tunnels: fix netns vs proto registration ordering

Following this email is a patch to restore the correct interface which
should fix the regression.  The bug itself is limited to the ip6_tunnel
tunnelling driver.  This driver is used for tunnelling non-ipv6 traffix in
ipv6 packets; this is not a tunnelling device for carrying ipv6 over ipv4.
Given the very low penetration of ipv6 as primary transport I surmise
this will give us a very very low exposure in our userbase.

Proposing for Lucid.
