[S390] mm: add ZONE_DMA to 31-bit config again
Add ZONE_DMA to 31-bit config again. The performance gain is minimal and hardly anybody cares anymore about a 31-bit kernel. So add ZONE_DMA again to help with SLAB_CACHE_DMA removal for !CONFIG_ZONE_DMA configurations. Acked-by: David Rientjes <rientjes@google.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
