Subject: [PATCH v6 11/21] arm64: topology: Remove redundant setting of llc_id in CPU topology
Date: Mon, 4 Jul 2022 11:15:55 +0100 [thread overview]
Message-ID: <20220704101605.1318280-12-sudeep.holla@arm.com> (raw)
In-Reply-To: <20220704101605.1318280-1-sudeep.holla@arm.com>
Since the cacheinfo LLC information is used directly in arch_topology,
there is no need to parse and fetch the LLC ID information only for
ACPI systems.
Just drop the redundant parsing and setting of llc_id in CPU topology
from ACPI PPTT.
