[PATCH v2 0/2] Additions to default DMA coherent pool

From: Vitaly Kuzmichev

v2:
Since linux-next now includes Vladimir Murzin's version of default DMA
coherent pool [1] our version is not required now and even causes merge
conflict. The difference between two versions is not really significant
except one serious problem with CONFIG_DMA_CMA. Please see patch v2 1/2
for details.
So that I have rebased our work on linux-next/master branch, and sending
this patchset with necessary additions for default DMA pool feature.

Patch v2 2/2 adds 'dmainfo' to ProcFS to show available DMA regions.
