Revert "mm: fail GFP_DMA allocations when ZONE_DMA is not configured"
This reverts commit a197b59a. As rmk says: "Commit a197b59a (mm: fail GFP_DMA allocations when ZONE_DMA is not configured) is causing regressions on ARM with various drivers which use GFP_DMA. The behaviour up until now has been to silently ignore that flag when CONFIG_ZONE_DMA is not enabled, and to allocate from the normal zone. However, as a result of the above commit, such allocations now fail which causes drivers to fail. These are regressions compared to the previous kernel version." so just revert it.
