--- Comment #1 from Serhei Makarov <me at serhei dot io> ---
Strictly speaking cpu0 is not always safe or possible to disable. But I was
able to do so on a test vm, so the fix has been committed just in case. (As
usual, before the fix stapbpf's error message is based on a failing syscall
return code, which fails to reveal the reason why things don't work.)
