+Subject: [PATCH 3854/4131] drm/amdgpu: Fix always_valid bos multiple LRU
+ insertions.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If these bos are evicted and are in the validated list
+things blow up, so do not put them in there. Notably,
+that tries to add the bo to the LRU twice, which results
+in a BUG_ON in ttm_bo.c.
+
+While for the bo_list an alternative would be to not allow
+always valid bos in there, that does not work for the user
+fence.
+
+v2: Fixed whitespace issue pointed out by checkpatch.pl
