File 0073-s390x-cpumodel-msa9-facility.patch of Package qemu-linux-user
From: Christian Borntraeger <borntraeger@de.ibm.com> Date: Mon, 29 Apr 2019 05:02:45 -0400 Subject: s390x/cpumodel: msa9 facility Provide the MSA9 facility (stfle.155). This also contains pckmo subfunctions for key wrapping. Keep them in a separate group to disable those as a block if necessary. This is for example needed when disabling key wrapping via the HMC.
