[PATCH v6 12/21] arch_topology: Drop LLC identifier stash from the CPU topology
From: Sudeep Holla <hidden>
Date: 2022-07-04 10:17:53
Also in:
linux-riscv, lkml
Subsystem:
driver core, kobjects, debugfs and sysfs, generic architecture topology, the rest · Maintainers:
Greg Kroah-Hartman, "Rafael J. Wysocki", Danilo Krummrich, Sudeep Holla, Linus Torvalds
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.
