Subject[PATCH 4.20 159/183] drm/amdgpu: disable bulk moves for now
Date
4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christian König <ckoenig.leichtzumerken@gmail.com>

commit a213c2c7e235cfc0e0a161a558f7fdf2fb3a624a upstream.

The changes to fix those are two invasive for backporting.

Just disable the feature in 4.20 and 5.0.
