[PATCH v2 0/2] Additions to default DMA coherent pool
From: Vitaly Kuzmichev
Date: Fri Jul 07 2017 - 09:22:51 EST
Since linux-next now includes Vladimir Murzin's version of default DMA
coherent pool  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
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.
