From edb9382175c3ebdced8ffdb3e0f20052ad9fdbe9 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Fri, 27 Oct 2017 04:42:37 +0200 Subject: sched/isolation: Move isolcpus= handling to the housekeeping code We want to centralize the isolation features, to be done by the housekeeping subsystem and scheduler domain isolation is a significant part of it. No intended behaviour change, we just reuse the housekeeping cpumask and core code.
