Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next

Conflicts:
	include/net/xfrm.h

Simple conflict between Joe Perches "extern" removal for function
declarations in header files and the changes in Steffen's tree.

Steffen Klassert says:

====================
Two patches that are left from the last development cycle.
Manual merging of include/net/xfrm.h is needed. The conflict
can be solved as it is currently done in linux-next.

1) We announce the creation of temporary acquire state via an asyc event,
   so the deletion should be annunced too. From Nicolas Dichtel.

2) The VTI tunnels do not real tunning, they just provide a routable
   IPsec tunnel interface. So introduce and use xfrm_tunnel_notifier
   instead of xfrm_tunnel for xfrm tunnel mode callback. From Fan Du.
