* 'agp-next' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/agp-2.6:
agp/intel: remove restore in resume
agp: fix uninorth build
intel-agp: Set dma mask for i915
agp: kill phys_to_gart() and gart_to_phys()
intel-agp: fix sglist allocation to avoid vmalloc()
intel-agp: Move repeated sglist free into separate function
agp: Switch agp_{un,}map_page() to take struct page * argument
agp: tidy up handling of scratch pages w.r.t. DMA API
intel_agp: Use PCI DMA API correctly on chipsets new enough to have IOMMU
agp: Add generic support for graphics dma remapping
agp: Switch mask_memory() method to take address argument again, not page
