I'm digging up an old thread here, but I've been working on a new page-table
allocator for the SMMU and looked into implementing this workaround for you
in there. When I do the TLBI on map after installing the new PTE, can I just
invalidate the range mapped by that PTE, or does it need to be a full TLBI?
