Zhenzhong Duan 6ce12bd297 intel_iommu: Introduce property "stale-tm" to control Transient Mapping (TM) field ... VT-d spec removed Transient Mapping (TM) field from second-level page-tables and treat the field as Reserved(0) since revision 3.2. Changing the field as reserved(0) will break backward compatibility, so introduce a property "stale-tm" to allow user to control the setting. Use pc_compat_9_1 to handle the compatibility for machines before 9.2 which allow guest to set the field. Starting from 9.2, this field is reserved(0) by default to match spec. Of course, user can force it on command line. This doesn't impact function of vIOMMU as there was no logic to emulate Transient Mapping.
