[PATCH v3 0/6] powerpc/perf: Export memory hierarchy level

[Madhavan Srinivasan]

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 information for a cache reload. Patchset exports
the hierarchy information to the user via the perf_mem_data_src
object from SIER.

Patchset is a rebase of the work posted previously with minor
updates to it.
