From 95b0e655f9148881907fdbe5baba6a9f5d094fee Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Thu, 9 Oct 2014 15:26:49 -0700 Subject: [PATCH] ARM: mm: don't limit default CMA region only to low memory DMA-mapping supports CMA regions places either in low or high memory, so there is no longer needed to limit default CMA regions only to low memory. The real limit is still defined by architecture specific DMA limit.
