yes, thats why i said '>> sorry, my reason was wrong though.' above

I thought the .config edit would have spit out an error message as the 
PERF_EVENT was reselected (basically print any such dependency changes it

I was only curious if you compiled by any chance as some of the folks were 
trying to get the Intel systems with RDT..
