This is changing the slot-walking code instead of updating
mem_avoid_overlap() -- that's where the check for a "reserved" memory
area should live.

For example, this is how both mem_avoid_memmap() and the setup_data
memory areas are handled.

Is there a reason mem_avoid_overlap() can't be used here?
