Subject: [GIT PULL 11/12] KVM: s390: Fix RRBE return code not being CC
Date: Wed,  1 Feb 2017 12:38:13 +0100	[thread overview]
Message-ID: <1485949094-138708-12-git-send-email-borntraeger@de.ibm.com> (raw)
In-Reply-To: <1485949094-138708-1-git-send-email-borntraeger@de.ibm.com>

From: Janosch Frank <frankja@linux.vnet.ibm.com>

reset_guest_reference_bit needs to return the CC, so we can set it in
the guest PSW when emulating RRBE. Right now it only returns 0.

Let's fix that.
