Yeah, it probably doesn't really matter all that much in the end -
people will refer to this with different names like with other features
in Linux anyway.

Start with a very simple interface to define full dynticks CPU:
use a boot time option defined cpumask through the "full_nohz="
kernel parameter.
Make sure you keep at least one CPU outside this range to handle
the timekeeping.
Also full_nohz= must match rcu_nocb= value.
