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

Steffen Klassert says:

====================
pull request (net-next): ipsec-next 2014-05-22

This is the last ipsec pull request before I leave for
a three weeks vacation tomorrow. David, can you please
take urgent ipsec patches directly into net/net-next
during this time?

I'll continue to run the ipsec/ipsec-next trees as soon
as I'm back.

1) Simplify the xfrm audit handling, from Tetsuo Handa.

2) Codingstyle cleanup for xfrm_output, from abian Frederick.

Please pull or let me know if there are problems.
====================
