McKenney" TREE03 has been especially effective at finding bugs lately. This commit makes it even more effective by speeding up its CPU hotplug testing and increasing its NR_CPUs from 8 to 16. TREE08's NR_CPUS is decreased from 16 to 8 in order to maintain the same test duration. Signed-off-by: Paul E.
