From 2b1a61f0a8c714c96277bf16a823a84bafa1397d Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 25 Dec 2008 13:39:23 +0100 Subject: [S390] cpu topology: introduce kernel parameter Introduce a topology=[on|off] kernel parameter which allows to switch cpu topology on/off. Default will be off, since it looks like that for some workloards this doesn't behave very well (on s390).
