[PATCH v5 3/6] KVM: arm64: Add mm_ops member for structure stage2_attr_data

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Also add a mm_ops member for structure stage2_attr_data, since we
will move I-cache maintenance for guest stage-2 to the permission
path and as a result will need mm_ops for address transformation.
