intel-gtt: introduce drm/intel-gtt.h Add a few definitions to it that are already shared and that will be shared in the future (like the number of stolen entries). No functional changes in here.

drm/i915/gtt: Allow >= 4GB sizes for vm. We can have exactly 4GB sized ppgtt with 32bit system. size_t is inadequate for this. v2: Convert a lot more places (Daniel) Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Michel Thierry <michel.thierry@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

drm/i915: die, i915_probe_agp, die Use the detection from intel-gtt.ko instead. Hooray! Also move the stolen mem allocator to the other gtt stuff in dev_prv->mem. v2: Chris Wilson noted that my error handling was crap. Fix it. He also said that this fixes a problem on his i845. Indeed, i915_probe_agp misses a special case for i830/i845 stolen mem detection.

drm/i915 + agp/intel-gtt: prep work for direct setup To be able to directly set up the intel-gtt code from drm/i915 and avoid setting up the fake-agp driver we need to prepare a few things: - pass both the bridge and gpu pci_dev to the probe function and add code to handle the gpu pdev both being present (for drm/i915) and not present (fake agp). - add refcounting to the remove function so that unloading drm/i915 doesn't kill the fake agp driver v2: Fix up the cleanup and refcount, noticed by Jani Nikula.

drm/i915: Replace the array of pages with a scatterlist Rather than have multiple data structures for describing our page layout in conjunction with the array of pages, we can migrate all users over to a scatterlist. One major advantage, other than unifying the page tracking structures, this offers is that we replace the vmalloc'ed array (which can be up to a megabyte in size) with a chain of individual pages which helps reduce memory pressure. The disadvantage is that we then do not have a simple array to iterate, or to access randomly. The common case for this is in the relocation processing, which will typically fit within a single scatterlist page and so be almost the same cost as the simple array. For iterating over the array, the extra function call could be optimised away, but in reality is an insignificant cost of either binding the pages, or performing the pwrite/pread. v2: Fix drm_clflush_sg() to not invoke wbinvd as well! And fix the trivial compile error from rebasing. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

drm/i915: disable ppgtt on snb when dmar is enabled Totally unexpected that this regressed. Luckily it sounds like we just need to have dmar disable on the igfx, not the entire system. At least that's what a few days of testing between Tony Vroon and me indicates.
