<title>drm/ttm, drm/vmwgfx: Use RCU locking for object lookups v3</title>

<content type='text'>
The mostly used lookup+get put+potential_destroy path of TTM objects
is converted to use RCU locks. This will substantially decrease the amount
of locked bus cycles during normal operation.
Since we use kfree_rcu to free the objects, no rcu synchronization is needed
at module unload time.

v2: Don't touch include/linux/kref.h
v3: Adapt to kref_get_unless_zero return value change

Use the more current logging style.

Add pr_fmt and remove the TTM_PFX uses.
Coalesce formats and align arguments.

There's no need to pass kref_put() the address of a function (just the
function will do just fine) nor to cast its unused return to void.

on 64 bit builds, so shrinking its size from 72 to 64 bytes allowing it
to fit into a smaller slab.

Add objects needed for user-space to maintain reference counts on ttm objects.
This is used by the vmwgfx driver which allows user-space to maintain
map-counts on dma buffers, lock-counts on the ttm lock and ref-counts on
gpu surfaces, gpu contexts and dma buffer.
