[PATCH v4 20/20] arch_topology: Warn that topology for nested clusters is not supported

From: Sudeep Holla
Date: Tue Jun 21 2022 - 15:23:45 EST


We don't support the topology for clusters of CPU clusters while the
DT and ACPI bindings theoritcally support the same. Just warn about the
same so that it is clear to the users of arch_topology that the nested
clusters are not yet supported.
