I can only find two `struct irq_chip's in arch/ia64 and they both have a .mask. And a .unmask. So perhaps that is a misreading of what oopsed. There are no changes in kernel/irq/ in -mm. Are you sure mainline doesn't do this too? Anyway, can you please take a closer look at exactly what pointer it is oopsing on? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
