Mapping the parent IRQ will use a virq number which may conflict with the hardcoded I8259A_IRQ_BASE..I8259A_IRQ_BASE+15 range that the i8259 driver expects to be free. If this occurs then we'll hit errors when adding the i8259 IRQ domain, since one of its virq numbers will already be in use. Avoid this by adding the i8259 domain before mapping the parent IRQ, such that the i8259 virq numbers become used before the parent interrupt controller gets a chance to use any of them.Hello, Any chance of getting reviews/acks on this & the following 2 patches in the series so Ralf can take them through the MIPS tree? The lack of these (well, patches 1 & 2 anyway) blocks applying many of the Malta patches later in the series.
