From dffc9efc562b8a2180e86df9f733cb113ba94b33 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Wed, 28 Jan 2009 17:07:19 +1000 Subject: [PATCH 1/1] m68knommu: mark all RAM as ZONE_DMA There is no reason not to put all RAM in ZONE_DMA for these simple m68k varients (same as the standard MMU m68k code does). With this in place the usual dma_alloc_coherent() work as expected.
