Also IVB needs its own pebs_constraint table as there is a new PEBS
event (0xd3):

+struct event_constraint intel_ivb_pebs_event_constraints[] = {
+       INTEL_UEVENT_CONSTRAINT(0x01c0, 0x2), /* INST_RETIRED.ALL */
+       INTEL_EVENT_CONSTRAINT(0xc2, 0xf),    /* UOPS_RETIRED.* */
+       INTEL_EVENT_CONSTRAINT(0xc4, 0xf),    /* BR_INST_RETIRED.* */
+       INTEL_EVENT_CONSTRAINT(0xc5, 0xf),    /* BR_MISP_RETIRED.* */
+       INTEL_EVENT_CONSTRAINT(0xcd, 0x8),    /* MEM_TRANS_RETIRED.* */
+       INTEL_EVENT_CONSTRAINT(0xd0, 0xf),    /* MEM_UOP_RETIRED.* */
+       INTEL_EVENT_CONSTRAINT(0xd1, 0xf),    /* MEM_LOAD_UOPS_RETIRED.* */
+       INTEL_EVENT_CONSTRAINT(0xd2, 0xf),    /*
MEM_LOAD_UOPS_LLC_HIT_RETIRED.* */
+       INTEL_EVENT_CONSTRAINT(0xd3, 0xf), /*
MEM_LOAD_UOPS_LLC_MISS.LOCAL_DRAM */
+       EVENT_CONSTRAINT_END
+};
