Robert Richter a1f2b70a94 perf, x86: Use weight instead of cmask in for_each_event_constraint() 
There may exist constraints with a cmask set to zero. In this case
for_each_event_constraint() will not work properly. Now weight is used
instead of the cmask for loop exit detection. Weight is always a value
other than zero since the default contains the HWEIGHT from the
counter mask and in other cases a value of zero does not fit too.

This is in preparation of ibs event constraints that wont have a
cmask.
