Hello!
This series provides a couple of patches that reduce the number of rcuo
kthreads in cases where nr_cpu_ids is larger than the actual number of
online CPUs.
1. Preparation patch that rationalizes RCU's creation of early-boot
kthreads.
2. Instead of creation rcuo kthreads for each possible CPU, create
them only for those CPUs that have come online at least once
since boot.
Thanx, Paul
