x86: DT: use for_each_of_cpu_node iterator (7de8f4aa) · Commits · 戴 / test

Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This has the side effect of defaulting to iterating using "cpu" node names in preference to the deprecated (for FDT) device_type == "cpu". Cc: Ingo Molnar <mingo@redhat.com> Cc: "H.
