Actually, this should be the syscall number that auditctl was compiled with.

I don't think so. How does it know what personalities you want to watch?

How about we make pers take a list? This could be implemented one of 2 ways. 
auditctl can generate a rule for each personality. Or with some changes in 
the kernel, we can make personality act more like a bit mask so that we don't 
have to load as many rules in the kernel.

Userspace can generate a mask or separate rules. Any preferences?
