I tested as same in other SoC. It looks fine.
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: 0.9415s total time: 0.9582s total time: 1.3275s total time: 1.6752s
R-Car H3 (misfit) total time: 0.9312s total time: 0.9429s total time: 0.9525s total time: 0.9660s
10 run summary (tracking longest running task for each run) R-Car H3 avg max tip 1.6752 1.6753 misfit 0.9890 1.0204
