Setting CONFIG_MAXSMP=y causes cpumasks to be moved offstack, which introduces the possibility of NULL cpumask_var_t pointers. This commit therefore enables CONFIG_MAXSMP=y in TREE01 to increase test coverage. However, because CONFIG_MAXSMP=y implies 8192 CPUs, we need to use the maxcpus= boot parameter to limit the number of CPUs to something reasonable, which in turn requires updating the scripts to handle this.
