Ignore events that are in off/error state or belong to a different PMU. This patch originates from the following commit for ARM by Will Deacon: - 65b4711ff513767341aa1915c822de6ec0de65cb ARM: 6352/1: perf: fix event validation The validate_event function in the ARM perf events backend has the following problems: 1.) Events that are disabled count towards the cost. 2.) Events associated with other PMUs [for example, software events or breakpoints] do not count towards the cost, but do fail validation, causing the group to fail. This patch changes validate_event so that it ignores events in the PERF_EVENT_STATE_OFF state or that are scheduled for other PMUs.
