[PATCH 1/8] drm/ttm: turn ttm_bo_device.vma_manager into a pointer
Rename the embedded struct vma_offset_manager, new name is _vma_manager.
ttm_bo_device.vma_manager changed to a pointer.
The ttm_bo_device_init() function gets an additional vma_manager
argument which allows to initialize ttm with a different vma manager.

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.

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.

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,
