The same comment about patch split as before. Please make splitting
out memory_map_from_high() a separate patch. Also, please choose one
pair to describe the direction. The series is currently using four
variants - top_down/bottom_up, high_to_low/low_to_high,
from_high/from_low. rev/[none]. Please choose one and stick with it.
