From 1f4170e12db06fdde5279d665a7e6e2976b2b623 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger <borntraeger@de.ibm.com> Date: Tue, 29 Jul 2008 23:48:42 +0200 Subject: KVM: s390: Fix kvm on IBM System z10 The z10 system supports large pages, kvm-s390 doesnt. Make sure that we dont advertise large pages to avoid the guest crashing as soon as the guest kernel activates DAT.
