v2 was doing some pretty nasty things with the DMA API, so I took a different approach for this v3. As suggested, this version uses ttm_dma_populate() to populate BOs. The reason for doing this was that it would entitle us to using the DMA sync functions, but since the memory returned is already coherent anyway, we do not even need to call these functions anymore. So this series has turned into

Hi guys, Well let's face it AGP is a total headache to maintain and dead for at least 10+ years. We have a lot of x86 specific stuff in the architecture independent graphics memory management to get the caching right, abusing the DMA API on multiple occasions, need to distinct between AGP and driver specific page tables etc etc... So the idea here is to just go ahead and remove the support

From: Maarten Lankhorst <maarten.lankhorst at canonical.com> Commit de7b7d59d54852c introduced tiled GART, but a linear copy is still performed. This may result in errors on eviction, fix it by checking tiling from memtype.
