You get: ACPI: HARDWARE addr space,NOT supported yet for each ACPI defined CPU which status is active, but exceeds maxcpus= count. As these "not booted" CPUs do not run an idle routine and echo X >/proc/acpi/processor/*/throttling did not work I couldn't find a way to really access not onlined/booted machines. Still this should get fixed and /proc/acpi/processor/X dirs of cores exceeding maxcpus should not show up. I wonder whether this could get cleaned up by truncating possible cpu mask and nr_cpu_ids to setup_max_cpus early some day (and not exporting setup_max_cpus anymore then). But this needs touching of a lot other places...
