#     powerpc/perf: Exclude pmc5/6 from the irrelevant PMU group constraints
#     
#     PMU counter support functions enforces event constraints for group of
#     events to check if all events in a group can be monitored. Incase of
#     event codes using PMC5 and PMC6 ( 500fa and 600f4 respectively ), not
#     all constraints are applicable, say the threshold or sample bits. But
#     current code includes pmc5 and pmc6 in some group constraints (like
#     IC_DC Qualifier bits) which is actually not applicable and hence
#     results in those events not getting counted when scheduled along with
#     group of other events. Patch fixes this by excluding PMC5/6 from
#     constraints which are not relevant for it.
#     
#     Fixes: 7ffd948 ("powerpc/perf: factor out power8 pmu functions")
