It's not even a rename even though it should be, it's adding yet another 
node_states that is equal to N_HIGH_MEMORY since that state already 
includes all memory.  It's just a matter of taste but I think we should be 
renaming it instead of aliasing it (unless you actually want to make 
N_HIGH_MEMORY only include nodes with highmem, but nothing depends on 
that).
