+
+	  The affected design reports FEAT_HAFDBS as not implemented in
+	  ID_AA64MMFR1_EL1.HAFDBS, but (V)TCR_ELx.{HA,HD} are not RES0
+	  as required by the architecture. The unadvertised HAFDBS
+	  implementation suffers from an additional erratum where hardware
+	  A/D updates can occur after a PTE has been marked invalid.
+
+	  The workaround forces KVM to explicitly set VTCR_EL2.HA to 0,
