The logic in e820_find_active_regions() for determining the true active regions for an e820 entry given a range of PFN's is needed for e820_hole_size() as well. e820_hole_size() is called from the NUMA emulation code to determine the reserved area within an address range on a per-node basis. Its logic should duplicate that of finding active regions in an e820 entry because these are the only true ranges we may register anyway.
