Stephane Eranian 85a16ef66c perf/x86/uncore: Export basic memory events for IVT IMC PMU 
This patch exposes two basic events for Ivytown IMC uncore PMU:

- cas_count_read: number of full-cache line reads to memory controller
- cas_count_write: number of full-cache line writes to memory controller

Those events use the same encoding as for SNB-EP, so reuse the same
event table. See specification in:

http://www.intel.com/content/dam/www/public/us/en/documents/manuals/xeon-e5-2600-v2-uncore-manual.pdf

By aggregating all the read and write events from all the memory controllers
of each processor socket, one can determine the total memory bandwidth utilization.
