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.
Of course for now, it is only called by memblock_is_region_reserved().
Will post a patch to do this.
Thanks.
Thanks.
