From 1c725922dd8274b6e0b370ad33cfaef9013fd70b Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 27 Aug 2012 15:43:49 +0200 Subject: [PATCH] s390/cpu hotplug: mask out CPU_TASKS_FROZEN in cu hotplug notifiers Unify all our cpu hotplug notifiers to mask out the CPU_TASKS_FROZEN bit, so we don't have to add all the *_FROZEN variant cases to the notifiers.
