When invalidating an IOVA range potentially spanning multiple pages, such as when removing an entire intermediate-level table, we currently only issue an invalidation for the first IOVA of that range. Since the architecture specifies that address-based TLB maintenance operations target a single entry, an SMMU could feasibly retain live entries for subsequent pages within that unmapped range, which is not good. Make sure we hit every possible entry by iterating over the whole range at the granularity provided by the pagetable implementation. Signed-off-by:
