--------------------------------

commit bbdbde2a upstream
Backport summary: backport to kernel 4.19.57 for ICX perf topdown support

Bit 15 of the PERF_CAPABILITIES MSR indicates that the perf METRICS
feature is supported. The perf METRICS is not a PEBS feature.

Rename pebs_metrics_available perf_metrics.

The bit is not used in the current code. It will be used in a later
patch.
