Valentin Schneider 254e090f3a FROMGIT: sched/uclamp: Make uclamp util helpers use and return UL values 
Vincent pointed out recently that the canonical type for utilization
values is 'unsigned long'. Internally uclamp uses 'unsigned int' values for
cache optimization, but this doesn't have to be exported to its users.

Make the uclamp helpers that deal with utilization use and return unsigned
long values.
