From c23f397cc4e440742b2b27690694c9346f638800 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Thu, 29 Jan 2015 14:09:54 +0100 Subject: [PATCH] KVM: s390: reenable LPP facility commit 7be81a46695d ("KVM: s390/facilities: allow TOD-CLOCK steering facility bit") accidentially disabled the "load program parameter" facility bit during rebase for upstream submission (my fault). Re-add that bit. As this is only for a performance measurement helper instruction (used by KVM itself) cc stable is not necessary see http://www-01.ibm.com/support/docview.wss?uid=isg26fcd1cc32246f4c8852574ce0044734a (SA23-2260 The Load-Program-Parameter and CPU-Measurement Facilities) for details about LPP and its usecase.
