For the overlap case, memblock_add_range() inserts the lower part and leave the upper part as indicated in the overlapped region. If the nid of the new range differs from the overlapped region, the information recorded is not correct. This patch adds a WARN_ON when the nid of the new range differs from the overlapped region.
