just to make sure the original point gets across: the warning is only in
the -rt tree, and it pinpoints potential SMP bugs. Does your box do
hyperthreading? If yes then this could be a live (but probably mostly
harmless) SMP bug. Maybe the whole IRQ disabling is unnecessary?
__devinit is mostly serialized, so i'm not sure there's any protection
needed against parallel IRQs?
