From 60b08c67220cf6faef7410ac6adba23a8a743bf7 Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Sun, 26 Feb 2006 04:18:22 +0100 Subject: [PATCH] x86_64: no_iommu removal in pci-gart.c In previous versions of pci-gart.c, no_iommu was used to determine if IOMMU was disabled in the GART DMA mapping functions. This changed in 2.6.16 and now gart_xxx() functions are only called if gart is enabled. Therefore, uses of no_iommu in the GART code are no longer necessary and can be removed. Also, it removes double deceleration of no_iommu and force_iommu in pci.h and proto.h, by removing the deceleration in pci.h. Lastly, end_pfn off by one error. Tested (along with patch 1/2) on dual opteron with gart enabled, iommu=soft, and iommu=off.
