Subject[PATCH v3 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 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.

Changelog v3:
-Removed is_load_store() and merged the same to get_memdata_src callback
-Added a check to update OP_LOAD or OP_STORE in data_src->val

Changelog v2:
-Updated the commit messages
-Fixed isa207_find_source() to consider all the possible sier[ldst] values.

Changelog v1:
- Fixed author-ship for the first patch and added suka's "Signed-off-by:".
