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.
