I have two more arm platform smsc911x conversion patches (realview and

irq_flags change, as they register their interrupts shared.  David: would 
it make sense to put this driver patch into the arm tree?

BTW, the shared-ness of an interrupt handler depends on how the interrupt
handler is written, not on whether you require the interrupt to be
exclusively owned or not.

So, if a driver is written to co-operate properly with shared interrupts
then it should always pass IRQF_SHARED.
