From 6721f77810dfcb7cbf8e97be6fa43fe2740dd0aa Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 9 Jan 2007 10:18:44 +0100 Subject: [S390] Fix cpu hotplug (missing 'online' attribute). 72486f1f8f0a2bc828b9d30cf4690cf2dd6807fc inverts the logic if an 'online' attribute in /sys/devices/system/cpu/cpuX should appear. So we end up with no hotpluggable cpus at all... Set the hotpluggable value to one to make sure the online attribute appears again.
