  : Fixes for concurrent S2 mapping race from Oliver:
  :
  : "So it appears that there is a race between two parallel stage-2 map
  : walkers that could lead to mapping the incorrect PA for a given IPA, as
  : the IPA -> PA relationship picks up an unintended offset. 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
