Ok, to not hold up the perf/urgent flow i zapped these two commits for the time being:
4a31beb: perf, x86: Fix handle_irq return values 8e3e42b: perf, x86: Try to handle unknown nmis with an enabled PMU
We can apply them if they take a form that dont introduce a different kind of (and more visible) regression.
Thanks,
Ingo
