From 94737a85f332aee75255960eaa16e89ddfa4c75a Mon Sep 17 00:00:00 2001 From: "George G. Davis" Date: Wed, 11 Feb 2015 15:26:27 -0800 Subject: [PATCH] mm: cma: fix totalcma_pages to include DT defined CMA regions The totalcma_pages variable is not updated to account for CMA regions defined via device tree reserved-memory sub-nodes. Fix this omission by moving the calculation of totalcma_pages into cma_init_reserved_mem() instead of cma_declare_contiguous() such that it will include reserved memory used by all CMA regions.
