sysfy.py inserts None for offline cpus in class cpus, method reload, via class cpu method reload. This is potentially useful, so we don't want to change these classes. However in cpuview.py - class cpuview, we don't want to display these offline cpus, so we only need to recognize that the type None can be returned and then skip over it.
