From: Zack Rusin <[e-mail]>

The series refactors the buffer object code to make more alike the
other ttm drivers. The placement becomes a property of the bo which makes
it a lot easier to correctly validate based on the current usage.
vmwgfx tends to do more validation due to forced moves, because the
buffer placement sometimes need to change due to userspace commands, i.e.
some commands e.g. SURFACE_DMA implies GMR's which are really deprecated
in favor of MOB's, but the x11 driver still uses GMR's so buffers tend
to flip between GMR's and MOB's a bit when running on X11.
                                                                           
The functionality remains largely unchanged, but the LOC are reduced by
about 400 and the groundwork is done for adding prime support with SG
ttm buffers.

Zack Rusin (7):
  drm/vmwgfx: Use the common gem mmap instead of the custom code
  drm/vmwgfx: Remove the duplicate bo_free function
  drm/vmwgfx: Rename vmw_buffer_object to vmw_bo
  drm/vmwgfx: Simplify fb pinning
  drm/vmwgfx: Cleanup the vmw bo usage in the cursor paths
  drm/vmwgfx: Abstract placement selection
  drm/vmwgfx: Stop using raw ttm_buffer_object's
