    Would kworker threads work for rcu? That would also avoid the shifting
    around of RCU threads for NOHZ configurations (which seems to have to be
    done manually right now). The kworker subsystem work that allows
    restriction to non NOHZ hardware threads would then also allow the
    shifting of the rcu threads which would simplify the whole endeavor.
