Keir:
        The proper patch is either to move RTC into hypervisor or modify
DM IRQ injection mechanism. I'd prefer to take the prior solution while
your concern is righ too as we are in RC1 now and want this size of
patch. For the later one, the change is much tricky and it may introduce
some regression issue and big imapct to other architecture like IA-64.
        So, what is your tradeoff now? We must fix this kind of bug,
right?
Thx,
Eddie
