aeaf45c5fd drm/nouveau: use bo->base.size instead of mem->num_pages
Change a couple of cases where it makes more sense to use the base size
instead of the number of pages in the resource.

213cc929cb Merge drm/drm-fixes into drm-next
msm-next pull request has a baseline with stuff from -fixes, roll
forward first.

Some simple conflicts in amdgpu, ttm and one in i915 where git gets
confused and tries to add the same function twice.

The underlying problem is not introduced by the commit, yet it uncovered the
underlying issue. The cited commit relies on valid pages. This is not given for
due to some bugs. For now, just warn and work around the issue by just ignoring

f07069da6b drm/ttm: move memory accounting into vmwgfx v4
This is just another feature which is only used by VMWGFX, so move
it into the driver instead.

I've tried to add the accounting sysfs file to the kobject of the drm
minor, but I'm not 100% sure if this works as expected.

v2: fix typo in KFD and avoid 64bit divide
v3: fix init order in VMWGFX
v4: use pdev sysfs reference instead of drm

f295c8cfec drm/nouveau: fix dma syncing warning with debugging on.
Since I wrote the below patch if you run a debug kernel you can a
dma debug warning like:
nouveau 0000:1f:00.0: DMA-API: device driver tries to sync DMA memory it has not allocated [device address=0x000000016e012000] [size=4096 bytes]

The old nouveau code wasn't consolidate the pages like the ttm code,
but the dma-debug expects the sync code to give it the same base/range
pairs as the allocator.

Fix the nouveau sync code to consolidate pages before calling the
sync code.

e11bfb99d6 drm/ttm: cleanup BO size handling v3
Based on an idea from Dave, but cleaned up a bit.

We had multiple fields for essentially the same thing.

Now bo->base.size is the original size of the BO in
arbitrary units, usually bytes.

bo->mem.num_pages is the size in number of pages in the
resource domain of bo->mem.mem_type.

v2: use the GEM object size instead of the BO size
v3: fix printks in some places

Purely conjecture, but I think the original locking inversion with the

shoudn't exist anymore with atomic: With atomic the bo pinning and

ebdf565169 drm/ttm: add multihop infrastrucutre (v3)
Currently drivers get called to move a buffer, but if they have to
move it temporarily through another space (SYSTEM->VRAM via TT)
then they can end up with a lot of ttm->driver->ttm call stacks,
if the temprorary space moves requires eviction.

Instead of letting the driver do all the placement/space for the
temporary, allow it to report back (-EMULTIHOP) and a placement (hop)
to the move code, which will then do the temporary move, and the
correct placement move afterwards.

This removes a lot of code from drivers, at the expense of
adding some midlayering. I've some further ideas on how to turn
it inside out, but I think this is a good solution to the call
stack problems.

v2: separate out the driver patches, add WARN for getting
MULTHOP in paths we shouldn't (Daniel)
v3: use memset (Christian)

4dbafbd30a drm/nouveu: fix swiotlb include
The check for swiotlb has moved to nouveu_ttm.c, but we forgot to move
the include as well.

This blows up only when merged with linux-next, not sure why drm-misc-next
works stand alone.

6a6e5988a2 drm/ttm: replace last move_notify with delete_mem_notify
The move notify callback is only used in one place, this should
be removed in the future, but for now just rename it to the use
case which is to notify the driver that the GPU memory is to be
deleted.

Drivers can be cleaned up after this separately.
