We may use IOCSR instead. In kernel/cpu-probe.c there are already some

It is difficult to find an area unused by HW for CSR method since the
small CSR ID range. However it is easy for cpucfg. Here I doubt whether

It's unfair to accuse the others for not knowing about LVZ considering
the lack of public documentation.
