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
