    arm64: ipipe: preserve the hard interrupt state across mayday trap · dec5e42f
    Philippe Gerum authored
    The mayday trap asks the co-kernel to deal with a runaway context
    which has been detected earlier. When doing so, the co-kernel might
    re-enable hard interrupts, which we have to disable again before
    unwinding the IRQ context which triggered the whole process (like a
    watchdog event).
    
    Use __ipipe_call_mayday() to fire the notification to the co-kernel
    instead of the open coded version, so that we do restore the hard
    interrupt state properly before leaving __ipipe_exit_irq().
