Rather than various and sundry names for a node's number, let's use 'nid'.
-Matt
In this file we refer to a node's number as 'nodeid', 'node', and 'nid'.
'nid' is more common than 'nodeid' or 'node' when referring to a node number
in VM code, so, for consistency, change mm/slab.c to reflect this.
Also, save a few dozen characters. :)
