Subject: [PATCH 2646/2944] perf/x86/rapl: Get rapl_cntr_mask from new probe framework

From: Jiri Olsa <[email-masked]>
Date: Sun, 16 Jun 2019 16:03:55 +0200

to #33635199

commit cd105aed1a9954605d693948efad86cd8e57cb1a upstream

We get rapl_cntr_mask from perf_msr_probe call, as a replacement
for current intel_rapl_init_fun::cntr_mask value for each model.
