I will of course continue testing, as I hope Mel and
the RT guys would soon too.

I stuffed the set into tip, tip-rt and the raspberrypi 5.14 branch
kernel+RT, and let my boxen run full LTP for exercise. As expected,
nothing the least bit interesting happened, just a bit of run to run
result diff noise due to.. deterministically challenged testcases.
