This was the same in my previous posting too. Before the topology update
happened, all the cpus would be in SMT, DIE. The topology updates can be
disabled using a kernel parameter topology_updates=off. Its documented under

      topology_updates= [KNL, PPC, NUMA] Format: {off} Specify if the kernel
      should ignore (off) topology updates sent by the hypervisor to this
      LPAR.

and is not something new in powerpc.
