[patch 164/262] memblock: drop memblock_free_early_nid() and memblock_free_early()

Andrew Morton

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: memblock: drop memblock_free_early_nid() and memblock_free_early()

memblock_free_early_nid() is unused and memblock_free_early() is an alias
for memblock_free().

Replace calls to memblock_free_early() with calls to memblock_free() and
remove memblock_free_early() and memblock_free_early_nid().
