As long as the removal is limited to list_count/list_count_nodes, that's 
fine. I only moved it from one file to another because the one and only 
function that was using it was being moved to the other file. If someone 
else has found a use for the same and wants to move it to a more common 
place then great. I assume there was no conflict happening in the i915 
specific code.
