[PATCH 0/6] powerpc/perf: Export memory hierarchy level

Power8/Power9 Perforence Monitoring Unit (PMU) supports different sampling modes (SM) such as Random Instruction Sampling (RIS), Random Load/Store Facility Sampling (RLS) and Random Branch Sampling (RBS). Sample mode RLS updates Sampled Instruction Event Register [SIER] bits with memory hierarchy
