Waiman Long 806087a518 cgroup/cpuset: Enable update_tasks_cpumask() on top_cpuset

[ Upstream commit ec5fbdfb99 ]

Previously, update_tasks_cpumask() is not supposed to be called with
top cpuset. With cpuset partition that takes CPUs away from the top
cpuset, adjusting the cpus_mask of the tasks in the top cpuset is
necessary. Percpu kthreads, however, are ignored.
