[Andrew Morton]

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

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

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().
