More of that horror. Don't.

Another option from what i proposed earlier is to actually have a function
inside mm/memblock to free it (memblock_free_arrays()) that does nothing
if memblock is to survive init.

I hate exporting variables or data structures like that. Functions are
semantically a lot cleaner.
