[merged] mircoblaze-drop-unneeded-numa-and-sparsemem-initializations.patch removed from -mm tree

[akpm@linux-foundation.org]

The patch titled
     Subject: mircoblaze: drop unneeded NUMA and sparsemem initializations
has been removed from the -mm tree.  Its filename was
     mircoblaze-drop-unneeded-numa-and-sparsemem-initializations.patch

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

------------------------------------------------------
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mircoblaze: drop unneeded NUMA and sparsemem initializations

microblaze does not support neither NUMA not SPARSMEM, so there is no
point to call memblock_set_node() and
sparse_memory_present_with_active_regions() functions during microblaze
memory initialization.

Remove these calls and the surrounding code.
