This patch series replaces __skb_alloc_pages with a much simpler function,

__skb_alloc_pages had an sk_buff pointer that was being passed as NULL in
call places where it was called. In a couple of cases the NULL was passed

The Intel drivers were pretty much just using the plain vanilla GFP flags
in their calls to __skb_alloc_page so this change makes it so that they use
netdev_alloc_page which just uses GFP_ATOMIC for the gfp_flags value.
