The check for whether a CPU required the FSB flush workaround previously required every CPU not requiring it to be whitelisted. That approach does not scale well as new CPUs are introduced so change the default from a WARN and returning an error to just returning 0. Any CPUs requiring the workaround can then be added to the blacklist.
