[PATCH 5.4 105/132] drm/msm: Split the a5xx preemption record

2020-09-15 Thread Greg Kroah-Hartman
From: Jordan Crouse commit 34221545d2069dc947131f42392fd4cebabe1b39 upstream. The main a5xx preemption record can be marked as privileged to protect it from user access but the counters storage needs to be remain unprivileged. Split the buffers and mark the critical memory as privileged. Cc:
