Subject: [RFC PATCH 0/2] Introduce interface for default DMA pool

Hi,

This is follow-up for Christoph complain of overloading the current
dma coherent infrastructure with the global pool. To address that I
implemented Robin's idea of the new interface to the global pool and
wire up it with (only existent user) ARM NOMMU.  Since I have not
heard from Vitaly and/or George of their use of global pool, I'm
leaving ARM MMU part to them.
