The prstate_housekeeping_conflict() function does check the HK_TYPE_DOMAIN housekeeping cpumask to make sure that CPUs outside of it can only be used in isolated partition. Given the fact that we are going to make housekeeping cpumasks dynamic, the current check may not be right anymore. Save the boot time HK_TYPE_DOMAIN cpumask and check against it instead of the upcoming dynamic HK_TYPE_DOMAIN housekeeping cpumask.

Why is (will be) checking against the stored HK_TYPE_DOMAIN mask correct when this mask becomes dynamic?
