If FEAT_PMUv3 is implemented and PMEVTYPER<n>(_EL0).MT bit is implemented as well, it is possible to control whether PMU counters take into account events happening on other threads. If FEAT_MTPMU is implemented, EL3 (or EL2) can override the MT bit leaving it to effective state of 0 regardless of any write to it. This patch introduces the DISABLE_MTPMU flag, which allows to diable multithread event count from EL3 (or EL2). The flag is disabled by default so the behavior is consistent with those architectures that do not implement FEAT_MTPMU.
