The quilt patch titled
Subject: mm: kill find_min_pfn_with_active_regions()
has been removed from the -mm tree. Its filename was

Subject: mm: kill find_min_pfn_with_active_regions()
Date: Mon, 15 Aug 2022 19:10:17 +0800
find_min_pfn_with_active_regions() is only called from free_area_init().
Open-code the PHYS_PFN(memblock_start_of_DRAM()) into free_area_init(),
and kill find_min_pfn_with_active_regions().
