From c681d0ba1252954208220ad32248a3e8e2fc98e4 Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Sat, 28 May 2011 13:15:05 -0500 Subject: [PATCH] intel-iommu: Use coherent DMA mask when requested The __intel_map_single function is not honoring the passed in DMA mask. This results in not using the coherent DMA mask when called from intel_alloc_coherent().
