Triggering an NMI on the NeXT causes multiple nested level 7 interrupt exceptions finally resulting in double bus fault. With the patch all seems to be fine. Maybe lastipl could be set in a different place of the cascading function calls (do_interrupt() > doint() > update_ipl()). Btw. intlev() is called twice or even more often in this cascade (even without any cycle exact mode).

Minor improvement: Checking intr > 0 is useless, as regs.intmask can never be negative (and negative return values for intlev() would be strange anyway).
