* kvm-arm64/vgic-its-fixes:
  : Fixes for vgic-its save/restore, courtesy of Kunkun Jiang and Jing Zhang
  :
  : Address bugs where restoring an ITS consumes a stale DTE/ITE, which
  : may lead to either garbage mappings in the ITS or the overall restore
  : ioctl failing. The fix in both cases is to zero a DTE/ITE when its
  : translation has been invalidated by the guest.
  KVM: arm64: vgic-its: Clear ITE when DISCARD frees an ITE
  KVM: arm64: vgic-its: Clear DTE when MAPD unmaps a device
  KVM: arm64: vgic-its: Add a data length check in vgic_its_save_*
