Argh.... GFP_THISNODE must use the nid passed to alloc_pages_node and 
*not* the local numa node id. Only if the node specified to alloc_pages 
nodes is -1 will this work.

alloc_pages_node() calls __alloc_pages_nodemask() though where in this
function if I'm reading it right is called without a node id. Given no
other details on the nid, the current one seemed a logical choice.

If the function only called when the first zone == numa_node_id then 
the use of numa_node_id here is okay.
