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

Regards,
Inami
