Subject: [ 047/135] ip_tunnel_core: Change __skb_push back to skb_push

3.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Steffen Klassert <steffen.klassert@...unet.com>

[ Upstream commit 78a3694d44a029242dd0830b34ab20ef1704be35 ]

Git commit 0e6fbc5b ("ip_tunnels: extend iptunnel_xmit()")
moved the IP header installation to iptunnel_xmit() and
changed skb_push() to __skb_push(). This makes possible
bugs hard to track down, so change it back to skb_push().
