Subject: [PATCH v6 12/21] arch_topology: Drop LLC identifier stash from the CPU topology
Date:   Mon,  4 Jul 2022 11:15:56 +0100
Message-Id: <20220704101605.1318280-13-sudeep.holla@arm.com>

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.
