Subject: [GIT PULL 2/2] KVM: s390: let ptff intercepts result in cc=3
Date: Wed, 20 Jul 2016 14:40:00 +0200	[thread overview]
Message-ID: <1469018400-8397-3-git-send-email-borntraeger@de.ibm.com> (raw)
In-Reply-To: <1469018400-8397-1-git-send-email-borntraeger@de.ibm.com>

From: David Hildenbrand <dahi@linux.vnet.ibm.com>

We don't emulate ptff subfunctions, therefore react on any attempt of
execution by setting cc=3 (Requested function not available).
