PATCH 1/1 perf vendor events intel: Fix Load_Miss_Real_Latency on SKL/SKX

From: Andi Kleen <[email protected]>

Fix incorrect event names for the Load_Miss_Real_Latency metric for Skylake and Skylake Server.

Fixes https://github.com/andikleen/pmu-tools/issues/158

Before:

% perf stat -M Load_Miss_Real_Latency true
event syntax error: '..ss.pending,mem_load_retired.l1_miss_ps,mem_load_retired.fb_hit_ps}:W'
\___ parser error

Usage: perf stat [<options>] [<command>]

-M, --metrics <metric/metric group list>
monitor specified metrics or metric groups (separated by ,)

After:

% perf stat -M Load_Miss_Real_Latency true

Performance counter stats for 'true':

           279,204      l1d_pend_miss.pending     #     14.0 Load_Miss_Real_Latency
             4,784      mem_load_uops_retired.l1_miss
            15,188      mem_load_uops_retired.hit_lfb
       0.000899640 seconds time elapsed
