[v3,00/13] drm/msm: drm scheduler conversion and cleanups

Message

From: Rob Clark <[e-mail]>

Conversion to gpu_scheduler, and bonus removal of
drm_gem_object_put_locked()

v2: Fix priority mixup (msm UAPI has lower numeric priority value as
    higher priority, inverse of drm/scheduler) and add some comments
    in the UAPI header to clarify.

    Now that we move active refcnt get into msm_gem_submit, add a
    patch to mark all bos busy before pinning, to avoid evicting bos
    used in same batch.

    Fix bo locking for cmdstream dumping ($debugfs/n/{rd,hangrd})

v3: Add a patch to drop submit bo_list and instead use -EALREADY
    to detect errors with same obj appearing multiple times in the
    submit ioctl bos table.  Otherwise, with struct_mutex locking
    dropped, we'd need to move insertion into and removal from
    bo_list under the obj lock.
