Commit Message

sparse report build warning as follows:

kernel/events/core.c:6493:6: warning: symbol
 'perf_pmu_snapshot_aux' was not declared. Should it be static?
kernel/events/core.c:10545:1: warning: symbol
 'dev_attr_nr_addr_filters' was not declared. Should it be static?
 
'perf_pmu_snapshot_aux' and 'dev_attr_nr_addr_filters' are not used
outside of this file, so mark them static.
