Currently, when the square root of the number of CPUs is rounded down by int_sqrt(), this round-down is applied to the number of callback kthreads per grace-period kthreads. This makes almost no difference for large systems, but results in oddities such as three no-CBs grace-period kthreads for a five-CPU system, which is a bit excessive. This commit therefore causes the round-down to apply to the number of no-CBs grace-period kthreads, so that systems with from four to eight CPUs have only two no-CBs grace period kthreads.
