Linus Torvalds 1fa7b6a29c Revert "mm: fail GFP_DMA allocations when ZONE_DMA is not configured" ...

This reverts commit a197b59ae6e8bee56fcef37ea2482dc08414e2ac.

As rmk says:
 "Commit a197b59ae6e8 (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.
