The patch titled
     Subject: mm: make early_pfn_to_nid() and related defintions close to each other
has been removed from the -mm tree.  Its filename was
     mm-make-early_pfn_to_nid-and-related-defintions-close-to-each-other.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Mike Rapoport <rppt@xxxxxxxxxxxxx>
Subject: mm: make early_pfn_to_nid() and related defintions close to each other

early_pfn_to_nid() and its helper __early_pfn_to_nid() are spread around
include/linux/mm.h, include/linux/mmzone.h and mm/page_alloc.c.

Drop unused stub for __early_pfn_to_nid() and move its actual generic
implementation close to its users.
