Hi all,

this is the next attempt to not return memory that is not DMA coherent
on coldfire/m68knommu.  The last one needed more fixups in the fec
driver, which this versions includes.  On top of that I've also added
a few more cleanups to the core dma allocation code.

Jim: any work to support the set_uncached and remap method for arm32
should probably be based on this, and patch 3 should make that
selection a little easier.
