The patch: mm: dmapool: use provided gfp flags for all dma_alloc_coherent() calls makes these calls on Kirkword and Orion5x redundent. The drivers are not making atomic requests for coherent memory and hence the default pool size is now sufficient.

Andrew, I'm going to hold onto this until we hear from the mm maintainers on the parent patch. If it doesn't make v3.8, I know we'll have to extend this patch to remove the similar code from mach-mvebu... thx, Jason.
