The housekeeping_update() will create an inverse of the pass-in isolated
cpumasks. As for the name, I add hk to indicate this cpumask is for
passing to housekeeping_update() to update housekeeping cpumask. It is
not directly related to the cpumasks in sched/isolation.c. Please let me
know if you have a suggestion for the name.
Cheers,
Longman
