All the LLC hits together.

Or it can be done with the PEBS memory latency event (like Lin-Ming's patch) or 
with mem_load_uops_retired (but then only for loads)

Don't set any of the LLC bits

Just don't set NON_DRAM


> #define SNB_REMOTE_DRAM

The current client SNBs for which those tables are don't have remote
DRAM.
