In speculative fault path, while doing page table lookup, offset is obtained at each level and value at that offset is read and checks are perfomed on it, later to get next level offset we read from previous level offset again. A concurrent page table reclaimation operation could result in change in value at this offset, and we go ahead and access it, this would result in reading an invalid entry. Fix this by reading from previous level offset again and comparing before performing next level access.
