The SchedTune CPU boosting API is currently used from sugov_get_util() to get the boosted utilization and to pass it into schedutil_cpu_util(). When UtilClamp is in use instead we call schedutil_cpu_util() by passing in just the CFS utilization and the clamping is done internally on the aggregated CFS+RT utilization for FREQUENCY_UTIL calls. This asymmetry is not required moreover, schedutil code is polluted by non-mainline SchedTune code. Wrap SchedTune API call related to cpu utilization boosting with a more generic and mainlinish UtilClamp call: - uclamp_rq_util_with(cpu, util, p) <= boosted_cpu_util(cpu) This new API is already used in schedutil_cpu_util() to clamp the aggregated RT+CFS utilization on FREQUENCY_UTIL calls. Move the cpu boosting into uclamp_rq_util_with() so that we remove any SchedTune specific bit from kernel/sched/cpufreq_schedutil.c. Get rid of the no more required boosted_cpu_util(cpu) method and replace it with a stune_util(cpu, util) which signature is better aligned with its uclamp_rq_util_with(cpu, util, p) counterpart.
