TTM/Nouveau cleanups
Hi guys,
I've already send this out in September last year, but only got a response from Daniel.
Could you guys please test this and tell me what you think about it?
Basically I'm trying to remove all driver specific features from TTM which don't need to be inside the framework.
Thanks,
Christian.

[PATCH 1/2] drm/nouveau: move io_reserve_lru handling into the driver
...lru,
so can't see anyone else to throw out?
Same problem really that ttm had (well still has I think for !amdgpu) with
its other lru ...
Or am I getting totally lost again here?

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

Moving LRU handling into Nouveau v3
Hi guys,
so I got some hardware and tested this and after hammering out tons of typos it now seems to work fine.
Could you give it more testing?
Thanks in advance,
Christian

Move io_reserve_lru handling into the driver
Just a gentle ping on this.
Already got the Acked-by from Daniel, but I need some of the
nouveau guys to test this since I can only compile test it.
Regards,
Christian.

[PATCH 1/3] drm/ttm: make sure that we always zero init mem.bus v2
We are trying to remove the io_lru handling and depend
on zero init base, offset and addr here.
v2: init addr as well
