Hello

With the .config that you give me in private, everything seems to work.
But with mine, the stacktrace still happen.
After some research, this is due to the following code:
cpumask_set_cpu(get_cpu(), &cci_pmu->cpus);
which disable preemption (via get_cpu())

So it is unrelated with your patch, I will send a bug report tomorow.

Okay, great to know that it is not related to my patches.

Furthermore, you can add:
Tested-by: Corentin Labbe <clabbe.montjoie@gmail.com>

Thanks, I have just sent a V2. I did not add your tested-by because
I have done some modifications. Could you test this new series and give
me your tested-by again? It would be great!

Thank you in advance,

Best regards,

Myl?ne
