Yeah if I could do it again, I would have rather created something like
cpu_isolation= (which name would conflict with isolcpus though) instead
of nohz_full=, because nohz_full= is really just a subset of what people
want.

But yeah if you guys want to create a new parameter that gathers nohz
and isolcpus I think we can.

task_isolation is really just about tasks so it should be another name.
