Subject: [PATCH v4 11/16] s390x: protvirt: Move diag 308 data over SIDAD
Date: Thu, 20 Feb 2020 07:56:33 -0500	[thread overview]
Message-ID: <20200220125638.7241-12-frankja@linux.ibm.com> (raw)
In-Reply-To: <20200220125638.7241-1-frankja@linux.ibm.com>

For protected guests the IPIB is written/read to/from the satellite
block, so we need those accesses to go through
s390_cpu_pv_mem_read/write().
