+ This option adds an alternative code sequence to work around Ampere
+ erratum AC03_CPU_38 on AmpereOne.
+
+ 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,
+ which avoids enabling unadvertised hardware Access Flag management
+ at stage-2.
