Thanks for a reminder. All are about kernel code being wrongly considered as user space.
At the beginning I was not sure if we need --no-userspace at all, but we
probably do for non-kernel projects which pass --userspace permanently via
configuration file.

1) The original regex was suggested by Joe and should mostly work, but using /
is indeed safer.
-m@^arch/.*\btools\b@
+m@^arch/.*/tools/@

2) my $userspace = 0 will indeed prevent --no-userspace from working as an
override. I did not considered this as important, but let's fix that.

3) return ($userspace || path based detection: dtto

=> v5

Kind regards,
Petr
