From 4f3dd8a06239c0a19d772a27c2f618dc2faadf4a Mon Sep 17 00:00:00 2001 From: Mark Nelson Date: Wed, 16 Jul 2008 05:51:47 +1000 Subject: powerpc/dma: Use the struct dma_attrs in iommu code Update iommu_alloc() to take the struct dma_attrs and pass them on to tce_build(). This change propagates down to the tce_build functions of all the platforms.
