We are currently not using cpusets but are simply isolating processors as
needed. Not sure that I want the overhead (administratively as well as in
kernel) to deal with this.

Someone may be using a different partitioning technique (like cgroups) etc
and then wont be able to use nohz. Having it not depend on cpusets makes
it more universal.
