[PATCH v9 00/18] drm/virtio: switch from ttm to gem shmem helpers.

[Gerd Hoffmann <kraxel@redhat.com>]

ttm increasingly gets into the way while hacking on virtio-gpu memory
management.  It also overkill for what virtio-gpu needs.  Lets get rid
of it.

v9:
 - rebase to latest dem-misc-next, adapt to changes.
 - fix issues found by Chia-I Wu.
v8:
 - rebase to latest drm-misc-next, adapt to changes.
v7:
 - rebase to latest drm-misc-next
 - reorder patches: switch all virtio commands to object array helpers
   first. then drop ttm, to make sure we don't release objects still in
   use.
 - misc fixes.
v6:
 - largely rewrite fencing logic, using the virtio_gpu_array_* helpers
 - add more patches to the series.
v5:
 - fence bugfixes.
 - minor optimizations.
v4:
 - make gem array helpers private to virtio.
 - misc minor fixes.
v3:
 - add gem array helpers.
 - rework fencing.

please review.

thanks,
  Gerd
