From 5c4991e24c69737bd41fc2737b1e3980abbf73f9 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Fri, 27 Oct 2017 04:42:34 +0200 Subject: sched/isolation: Split out new CONFIG_CPU_ISOLATION=y config from CONFIG_NO_HZ_FULL Split the housekeeping config from CONFIG_NO_HZ_FULL. This way we finally separate the isolation code from NOHZ. Although a dependency to CONFIG_NO_HZ_FULL remains for now, while the housekeeping code still deals with NOHZ internals.
