Interesting. The model is then to switch over to __set_irq_handler(),
or maybe set_irq_chip_and_handler(), to replace the toplevel dispatch
code for will-be-threaded IRQs which happen to be hooked up to inputs
that don't sense edges. (Agree, that seems like a goof. But hardware
designers sometimes have any choices there.)

The normal model is that boards don't get involved with that level of
logic ... all IRQs get set up once on generic code, and flow handlers
don't change. Or if they do change, it's done when changing the IRQ's
trigger mode from edge to level, or vice versa.

Can that be cleaned up a bit, so that the handle_level_oneshot_irq()
and unmask_oneshot_irq() stuff kicks in automatically when needed,
instead of requiring board-specific (or driver-specific) code to get
that stuff right?
