This series : eliminates the problem by using the current IPA of the walk as the : source-of-truth regarding where we are in a map operation." : . KVM: arm64: Constify start/end/phys fields of the pgtable walker data KVM: arm64: Infer PA offset from VA in hyp map walker KVM: arm64: Infer the PA offset from IPA in stage-2 map walker Signed-off-by: Marc Zyngier --- c3a62df457ff9ac8c77efe6d1eca2855d399355d
