You say `cluster identifier` which to me refers to
`cpu_topology[cpu].cluster_id`. But I guess you meant `cluster node`
from cpu-map DT node?

Otherwise you say we link (1.level) cpu-map cluster nodes to
`cluster_id\_sibling`? But then (1) we will never support nested
clusters and (2) why would we need llc support then?
