RE: [PATCH] Add irq host and hwirq pair fields to outputwhenshowing interrupts.

Yes, at least for now. Maybe if we can convince ourselves that nothing
significant would break of changing /proc/interrupts, then we can add
stuffs to it, but I'd rather avoid.

In the mpic, the host name can be the mpic->name, is it ok?

For MPIC it should probably be the OF full path
