The first two patches are based on the two cpuset patches from the "timers: Exclude isolated cpus from timer migration" patch series [1] with some modifications. They add additional nohz_full housekeeping mask check to ensure that there is at least one common housekeeping CPU that is not domain and nohz_full isolated. The last patch is another cleanup patch to simplify the current partition code.
