I have tested this on our R-Car again and it works well. In addition,
I confirmed that this patch-set also brings performance improvement to
other benchmarks(e.g. memory load latency in LMbench). You can add:

Tested-by: Gaku Inami <gaku.inami.xh@renesas.com>

The patches have been tested on:
3. Renesas R-Car H3 : 4+4 Cortex A57/A53

Results:
Single runs with completion time of each task
R-Car H3 (tip)
total time: 0.9435s
total time: 0.9952s
total time: 1.3511s
total time: 1.6747s

R-Car H3 (misfit)
total time: 0.9387s
total time: 0.9280s
total time: 0.9616s
total time: 0.9934s

10 run summary (tracking longest running task for each run)
R-Car H3
avg max
tip 1.6737 1.6758
misfit 0.9980 1.0409

Regards,
