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. https://lkml.org/lkml/2015/6/11/92 Changelog v1: - Fixed author-ship for the first patch and added suka's "Signed-off-by:".
