Subject: [net-next PATCH 0/5] Replace __skb_alloc_pages with much simpler
 function

This patch series replaces __skb_alloc_pages with a much simpler function,
__netdev_alloc_pages.  The main difference between the two is that
__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
by variable and this led to unnecessary code being run.

As such in order to simplify things the __netdev_alloc_pages call only
takes a mask and the page order being requested.  In addition it takes
advantage of several behaviors already built into the page allocator so
that it can just set GFP flags unconditionally.
