Again, notabug - we did disable_irq().
but does disable_irq() work in the light of that irqpoll stuff?
Don't have a clue what you're referring to, sorry.
misrouted_irq() in kernel/irq/spurious.c
afaics that calls all handlers registered to the system regardless of what
irq number they are registered for.....
which breaks the disable_irq() locking trick... because your irq handler now
gets called anyway!
