From: "Paul E. McKenney" <paulmck@kernel.org>
Leaving off the kvm.sh script's --cpus argument results in the script testing the scenarios sequentially, which can be quite slow. However, having to specify the actual number of CPUs can be error-prone. This commit therefore adds a --allcpus argument that causes kvm.sh to use all available CPUs.
