Subject: [PATCH] intel_agp: Use PCI DMA API correctly on chipsets new enough
 to have IOMMU

When graphics dma remapping engine is active, we must fill
gart table with dma address from dmar engine, as now graphics
device access to graphics memory must go through dma remapping
table to get real physical address.

Add this support to all drivers which use intel_i915_insert_entries()
