From 5b8dc787ce4a45c87254d1b0b22f161347ab7f81 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Mon, 4 Jul 2022 11:15:56 +0100 Subject: [PATCH] arch_topology: Drop LLC identifier stash from the CPU topology Since the cacheinfo LLC information is used directly in arch_topology, there is no need to parse and store the LLC ID information only for ACPI systems in the CPU topology. Remove the redundant LLC ID from the generic CPU arch_topology information.
