Currently, the personality(2) system call always returns the previous
persona. However, according to the manpage, it should return the previous
persona when successful and -1 otherwise. The following patch to
lookup_exec_domain() should remedy this behavior:

Actually I think that problem was already fixed. However, this looks
like it fixes another problem I've seen though where personality doesn't
return EINVAL if you pass it a bad personality. Right fix, wrong bug :)
