Subject: [PATCH 8/9] perf/x86/msr: Add Tiger Lake CPU support

From: Kan Liang <kan.liang@...ux.intel.com>

Tiger Lake is the followon to Ice Lake. PPERF and SMI_COUNT MSRs are
also supported.

The External Design Specification (EDS) is not published yet. It comes
from an authoritative internal source.

The patch has been tested on real hardware.
