[PATCH 0/2] iommu/io-pgtable-arm: Fix for stage-2 map/unmap

[Mostafa Saleh]

The first patch is a bug fix for stage-2 handling of concatenated pgds
that can break map/unmap for some cases.

The second patch is adding these cases to selfs tests.

While looking at that, I also noticed that the concated page tables support
is minimal and not supported for many cases (level = 0, 2, 3), I wrote some
code to support that so I can test further, I can send it later in another
patch.
