de3688e469 drm/ttm: add ttm_resource_fini v2 
Make sure we call the common cleanup function in all
implementations of the resource manager.

v2: fix missing case in i915, rudimentary kerneldoc, should be
    filled in more when we add more functionality

cb1c81467a drm/ttm: flip the switch for driver allocated resources v2 
Instead of both driver and TTM allocating memory finalize embedding the
ttm_resource object as base into the driver backends.

v2: fix typo in vmwgfx grid mgr and double init in amdgpu_vram_mgr.c

e34b8feeaa drm/ttm: merge ttm_dma_tt back into ttm_tt 
It makes no difference to kmalloc if the structure
is 48 or 64 bytes in size.

2966141ad2 drm/ttm: rename ttm_mem_reg to ttm_resource. 
This name better reflects what the object does. I didn't rename
all the pointers it seemed too messy.

f9463a4bc8 drm/nouveau/mmu: implement new vmm frontend 
These are the new priviledged interfaces to the VMM backends, and expose
some functionality that wasn't previously available.

It's now possible to allocate a chunk of address-space (even all of it),
without causing page tables to be allocated up-front, and then map into
it at arbitrary locations.  This is the basic primitive used to support
features such as sparse mapping, or to allow userspace control over its
own address-space, or HMM (where the GPU driver isn't in control of the
address-space layout).

Rather than being tied to a subtle combination of memory object and VMA
properties, arguments that control map flags (ro, kind, etc) are passed
explicitly at map time.

The compatibility hacks to implement the old frontend on top of the new
driver backends have been replaced with something similar to implement
the old frontend's interfaces on top of the new frontend.

7b8656636a drm/nouveau: directly handle comptag allocation 
Another transition step to allow finer-grained patches transitioning to
new MMU backends.

Old backends will continue operate as before (accessing nvkm_mem::tag),
and new backends will get a reference to the tags allocated here.
