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

From: David Miller <davem@davemloft.net>

We have seen a couple of __alloc_pages() failures due to
fragmentation, there is plenty of free memory but no large order pages
available.  I think the problem is in sock_alloc_send_pskb(), the
gfp_mask includes __GFP_REPEAT but its never used/passed to the page
allocator.  Shouldnt the gfp_mask be passed to alloc_skb() ?
