Subject: [PATCH v4 11/20] arch_topology: Drop LLC identifier stash from the CPU topology
Date: Tue, 21 Jun 2022 20:20:25 +0100	[thread overview]
Message-ID: <20220621192034.3332546-12-sudeep.holla@arm.com> (raw)
In-Reply-To: <20220621192034.3332546-1-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.
