unsigned is already of type int, so you're saying these occurrences should 
become signed, but that's not true since they never return NUMA_NO_NODE.  
They are all safe returning unsigned.

And alloc_page_interleave() doesn't exist anymore since the sched/numa 
bits were merged into sched/core, so nobody could apply this patch anyway.
