Subject: [PATCH v4 14/16] s390x: protvirt: Handle SIGP store status correctly
Date: Thu, 20 Feb 2020 07:56:36 -0500	[thread overview]
Message-ID: <20200220125638.7241-15-frankja@linux.ibm.com> (raw)
In-Reply-To: <20200220125638.7241-1-frankja@linux.ibm.com>

Status storing is not done by QEMU anymore, but is handled by SIE.
