Power7 and Power8 processors save the memory hierarchy level (eg: L2, L3) from which a load or store instruction was satisfied. Export this hierarchy information to the user via the perf_mem_data_src object.
Thanks to input from Stephane Eranian, Michael Ellerman, Michael Neuling and Anshuman Khandual.
