Subject: [git pull] AGP tree for merging
Hi Linus,
Please pull the 'agp-next' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/agp-2.6.git agp-next
This contains mainly a bunch of patches from dwmw2 to bring AGPs
use of the PCI DMA up to modern standards for use with IOMMUs.
Dave.

agp/intel: remove restore in resume
As early pci resume has already restored config for host
bridge and graphics device, don't need to restore it again,
This removes an original order hack for graphics device restore.
This fixed the resume hang issue found by Alan Stern on 845G,
caused by extra config restore on graphics device.

intel-agp: Set dma mask for i915
If DMAR is configured in but absent, we really do want to make sure that
the dma mask is set appropriately. Otherwise we get mapping failures on
highmem. Spotted by Zhenyu Wang.

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()

agp: Add generic support for graphics dma remapping
New driver hooks for support graphics memory dma remapping
are introduced in this patch. It makes generic code can
tell if current device needs dma remapping, then call driver
provided interfaces for mapping and unmapping. Change has
also been made to handle scratch_page in remapping case.

agp: Switch mask_memory() method to take address argument again, not page
In commit 07613ba2 ("agp: switch AGP to use page array instead of
unsigned long array") we switched the mask_memory() method to take a
'struct page *' instead of an address. This is painful, because in some
cases it has to be an IOMMU-mapped virtual bus address (in fact,
shouldn't it _always_ be a dma_addr_t returned from pci_map_xxx(), and
we just happen to get lucky most of the time?)
