From 53cbcbcf4362ef39e0a692b1d23c395999397fca Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Thu, 17 Nov 2011 13:11:21 +0100 Subject: [PATCH] ARM: 7166/1: Use PMD_SHIFT instead of PGDIR_SHIFT in dma-consistent.c Commit 99d1717d (ARM: Add init_consistent_dma_size()) introduces dynamic allocation of the consistent_pte array. The number of PTEs should be calculated based on the number of PMD entries rather than PGD, hence the PMD_SHIFT.
