The rcutorture tests run by default range from using one CPU to using sixteen of them. Therefore, rcutorture testing could be sped up significantly simply by running the kernels in parallel. Building them in parallel is not all that helpful: "make -j" is usually a better bet. So this commit takes a new "--cpus" argument that specifies how many CPUs rcutorture is permitted to use for its parallel runs. The default of zero does sequential runs as before. The bin-packing is minimal, and will be grossly suboptimal for some configurations. However, powers of two work reasonably well. Signed-off-by: Paul E.
