The IBM Olympic driver assumes that the call to create_proc_read_entry 
always succeeds. This patch simply logs appropriately whether in 
actuality it was created or not.

This falls under the 'Audit return codes (and handle failure correctly) 
for create_proc_*()' item on the TODO list. Also added KERN_* constants
as per Christophe Lucas' recommendation.
