Moving LRU handling into Nouveau v2
Hi guys,
I already tried this a few month ago, but since I don't have NVidia hardware its rather hard to test for me (need to get some ordered).
Dave brought up the topic that we should probably try to move the handling into Nouveau once more, so I tried to fix the problem Ben reported and rebased on top of current drm-misc-next.
Dave can you test this? At least in theory the approach

[RFC] Deprecate AGP GART support for Radeon/Nouveau/TTM
Unfortunately AGP is still to widely used as we could just drop support for using its GART.
Not using the AGP GART also doesn't mean a loss in functionality since drivers will just fallback to the driver specific PCI GART.
For now just deprecate the code and don't enable the AGP GART in TTM even when general AGP support is available.
Please comment,
Christian.
