Hi, Ben, Thanks! Please see my inline comments.

Is there any problem when the relationship between hosts and nodes is not 1:1? The mapping method is defined in irq_alloc_host(). If there is only one host for many nodes, then these nodes will use the same mapping. Such as iic_host, the IRQ_HOST_MAP_LINEAR is used for its all nodes. We do _not_ care which node, we just care which virq is mapped from which host's hw irq. > > Anyway, I discussed with Michael today and it might be a good idea to > provide an optional device node field in the host struct that can be > used by the majority of the PICs that have one host == one node, that > would provide a good default for the name() function. > But we have some irq host which has not OF-node bound.
