Sorry. Left that out...

include/linux/nodemask.h

#define any_online_node(mask) \
({ \
int node; \
for_each_node_mask(node, (mask)) \
if (node_online(node)) \
break; \
node; \
})

arch/powerpc/mm/numa.c is the only other user of that macro. In that
file the local variable is called nid, hence the name change in this
patch.
