Subject: [PATCH 0/4] drm/v3d: Add drm core helper, use shmem helpers

This was inspired by Rob's respin of the shmem helpers patch for
panfrost (which the final patch depends on).  And, looking at panfrost
and lima, recently I realized that we all had some nasty cargo-cult
code for BO reservations that we can share now that the reservation
object is in the core GEM struct.

Eric Anholt (4):
  drm: Add helpers for locking an array of BO reservations.
  drm/v3d: Use drm_gem_lock_reservations()/drm_gem_unlock_reservations()
  drm/v3d: Remove some dead members of struct v3d_bo.
  drm/v3d: Use the new shmem helpers to reduce driver boilerplate.
