Andrew,
Now that we finally have Soren Moch's (sp? sorry) cache exhaustion solved, can we respin this for v3.11? I'd like to include mvebu as well if possible.
For mvebu, I can do a follow-up patch, or Andrew can directly add it to his patch.
Applied to mvebu/cleanup with a few minor typo corrections and I added the hunk for mach-mvebu/.
thx,
Jason.

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.
