Subject: [PATCH v3 16/17] s390x: protvirt: Handle SIGP store status correctly
Date: Fri, 14 Feb 2020 10:16:35 -0500 [thread overview]
Message-ID: <20200214151636.8764-17-frankja@linux.ibm.com> (raw)
In-Reply-To: <20200214151636.8764-1-frankja@linux.ibm.com>
Status storing is not done by QEMU anymore, but is handled by SIE.
