Comment 1 for bug 1687629

"perf/x86: Avoid exposing wrong/stale data in intel_pmu_lbr_read_32()" required adapting the target file from arch/x86/kernel/cpu/perf_event_intel_lbr.c to arch/x86/events/intel/lbr.c due to "perf/x86: Move perf_event_intel_lbr.c ........ => x86/events/intel/lbr.c" being backported for bug #1559914.
