evsel__is_aux_event() identifies AUX area tracing selected events.
S390_CPUMSF uses a raw event type (PERF_TYPE_RAW - refer s390_cpumsf_evsel_is_auxtrace()) not a PMU type value that could be checked in evsel__is_aux_event(). However it sets needs_auxtrace_mmap (refer auxtrace_record__init()), so check that first.
Currently, the features that use evsel__is_aux_event() are used only by Intel PT, but that may change in the future.

Namhyung, could we get patches 5 and 6 from this series applied? They are independent and Leo's new patch set is dependent on patch 5.
I'm getting those two into tmp.perf-tools-next, probably should pick the rest as peterz has the kernel bits already in his queue.git/perf/core, right?
