For the *first* superpage in the new mapping, we were correctly¹ freeing the old bottom-level page table page and clearing the link to it, before installing the superpage. For subsequent superpages, however, we weren't. This causes a memory leak, and a warning about setting a PTE which is already set. ¹ Well, not *entirely* correctly. We just free the page table pages right there and then, which is wrong. In fact they should only be freed *after* the IOTLB is flushed so we know the hardware will no longer be looking at them.... and in fact I note that the IOTLB flush is completely missing from the intel_iommu_map() code path, although it needs to be there if it's permitted to overwrite existing mappings. Fixing those is somewhat more intrusive though, and will probably need to wait for 4.4 at this point" * tag 'for-linus-20151021' of git://git.infradead.org/intel-iommu: iommu/vt-d: fix range
