From 0d688da5505d77bcef2441e0a22d8cc26459702d Mon Sep 17 00:00:00 2001 From: Yasunori Goto Date: Tue, 3 Feb 2009 10:52:03 +0900 Subject: [PATCH] IA64: fix swiotlb alloc_coherent for non DMA_64BIT_MASK devices, fix Because dma_alloc_coherent() always required DMA zone even if DMA is NOT necessary, FUJITA Tomonori posted a patch to fix it: http://marc.info/?l=linux-ia64&m=123314730923356&w=2 However, this fix needs one more patch to fix completely. I tested and confirmed dma_alloc_coherent() returns correct zone after applied following patch.
