[merged] memblock-make-memblock_debug-and-related-functionality-private.patch removed from -mm tree

[akpm@linux-foundation.org]

The patch titled
     Subject: memblock: make memblock_debug and related functionality private
has been removed from the -mm tree.  Its filename was
     memblock-make-memblock_debug-and-related-functionality-private.patch

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

------------------------------------------------------
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: memblock: make memblock_debug and related functionality private

The only user of memblock_dbg() outside memblock was s390 setup code and
it is converted to use pr_debug() instead.  This allows to stop exposing
memblock_debug and memblock_dbg() to the rest of the kernel.
