This was discussed back in February:
https://lkml.org/lkml/2014/2/18/956
But I never saw a patch come out of it.
On IvyBridge we share the SandyBridge cache event tables, but the
dTLB-load-miss event is not compatible. Patch it up after
the fact to the proper DTLB_LOAD_MISSES.DEMAND_LD_MISS_CAUSES_A_WALK
