Thanks. I've rebased the tree so that it isn't based on my other iommu
changes, which are largely irrelevant. Since the drm-2.6.git tree as
advertised in MAINTAINERS seems to be a pristine 2.6.29-rc2, I've done
it based on 2.6.31-rc5 instead.
Dave, please pull from
git://git.infradead.org/~dwmw2/iommu-agp.git
David Woodhouse (6):
agp: Switch mask_memory() method to take address argument again, not page
agp: tidy up handling of scratch pages w.r.t. DMA API
agp: Switch agp_{un,}map_page() to take struct page * argument
intel-agp: Move repeated sglist free into separate function
intel-agp: fix sglist allocation to avoid vmalloc()
agp: kill phys_to_gart() and gart_to_phys()
Zhenyu Wang (2):
agp: Add generic support for graphics dma remapping
intel_agp: Use PCI DMA API correctly on chipsets new enough to have IOMMU
