The patch titled
     Subject: h8300, nds32, openrisc: simplify detection of memory extents
has been removed from the -mm tree.  Its filename was
     h8300-nds32-openrisc-simplify-detection-of-memory-extents.patch

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

------------------------------------------------------
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: h8300, nds32, openrisc: simplify detection of memory extents

Instead of traversing memblock.memory regions to find memory_start and
memory_end, simply query memblock_{start,end}_of_DRAM().
