    SUPPORT: downgrade Physical CPU Hotplug to Experimental
    
    The feature is not commonly used, and we don't have hardware to test it,
    not in OSSTest, not in Gitlab, and not even ad-hoc manually by community
    members. We could use QEMU to test it, but even that it is known not to
    work on our end.
    
    Also take the opportunity to rename the feature to "ACPI CPU Hotplug"
    for clarity.
