PopulateLevel2PageTable () is invoked for [parts of] mappings that start or end on a non-1 MB aligned address (or both). The size of the mapping depends on both the start address modulo 1 MB and the length of the mapping, but the logic that calculates this size is flawed: subtracting 'start address modulo 1 MB' could result in a negative value for the remaining length, which is obviously wrong. So instead, take either RemainLength, or the rest of the 1 MB block, whichever is smaller.
