Subject: [PATCH AUTOSEL 5.15 04/12] perf/x86/intel: Add Emerald Rapids

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

[ Upstream commit 6795e558e9cc6123c24e2100a2ebe88e58a792bc ]

>From core PMU's perspective, Emerald Rapids is the same as the Sapphire
Rapids. The only difference is the event list, which will be
supported in the perf tool later.
