I think we could simplify things quite a bit if we either
1. Add any cpus specified with nohz_full/extended=xxx to rcu_nocb. No check is then necessary anymore.
or
2. Avoid the setting of cpus entirely? If full nohz mode is desired then pick one cpu (f.e. the first one or the one that is used for xtime updates) and then make all other cpus nohz. Set the affinity mask for the rcuoXXX threads to that cpu.
