+Subject: [PATCH] hw/arm/smmuv3: Fill the IOTLBEntry leaf field on NH_VA
+ invalidation
+
+Let's propagate the leaf attribute throughout the invalidation path.
+This hint is used to reduce the scope of the invalidations to the
+last level of translation. Not enforcing it induces large performance
+penalties in nested mode.
