+Subject: [PATCH 4492/5725] drm/amdkfd: Fix race between scheduler and context
+ restore
+
+The scheduler may raise SQ_WAVE_STATUS.SPI_PRIO via SQ_CMD before
+context restore has completed. Restoring SPI_PRIO=0 after this point
+may cause context save to fail as the lower priority wavefronts
+are not selected for execution among spin-waiting wavefronts.
+
+Leave SPI_PRIO at its SPI-initialized or scheduler-raised value.
+
+v2: Also fix race with exception handler
+
