Subject[PATCH 1/2] perf/core: fix should it be static warnings
Date
Fixes the following sparse warnings:

kernel/events/core.c:199:6: warning: symbol
'update_perf_cpu_limits' was not declared. Should it be static?
kernel/events/core.c:475:6: warning: symbol 'perf_cgroup_switch'
was not declared. Should it be static?
kernel/events/core.c:7753:12: warning: symbol 'perf_init_event'
was not declared. Should it be static?
