area_src and area_dst are saved at the beginning of the function if chunk_size > page_size. The intention is quite clearly to restore them at the end based on the same condition, but step_size is considered instead of chunk_size. Considering that step_size is a number of pages, the condition is likely to be false. Use the same condition as when saving so that the globals are restored as intended.
