Harald Freudenberger a5867bb197 s390/zcrypt: handle new reply code FILTERED_BY_HYPERVISOR ... [ Upstream commit 6733775a92 ] This patch introduces support for a new architectured reply code 0x8B indicating that a hypervisor layer (if any) has rejected an ap message. Linux may run as a guest on top of a hypervisor like zVM or KVM. So the crypto hardware seen by the ap bus may be restricted by the hypervisor for example only a subset like only clear key crypto requests may be supported. Other requests will be filtered out - rejected by the hypervisor. The new reply code 0x8B will appear in such cases and needs to get recognized by the ap bus and zcrypt device driver zoo.
