Ugh.... can you please change memblock_overlaps_region() to return
bool instead?
Well, I think memblock_overlaps_region() is designed to return
the index of the region overlapping with the given region.
Maybe it had some users before.
Of course for now, it is only called by memblock_is_region_reserved().
It is OK to change the return value of memblock_overlaps_region() to bool.
But any caller of memblock_is_region_reserved() should also be changed.
I think it is OK to leave it there.
Thanks.
Thanks.
