[PATCH AUTOSEL 4.19 67/97] perf vendor events intel: Fix Load_Miss_Real_Latency on SKL/SKX

[Sasha Levin]

From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

[ Upstream commit 91b2b97025097ce7ca7536bc87eba2bf14760fb4 ]

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
