    More or less. Xen currently uses 6 per-cpu event channels, and it maps
    each to its own irq. My plan is to allocate just 6 irqs, map 6 vectors
    to them, and bind each event channel to a vector/cpu pair. If nothing
    else, it will make /proc/interrupts somewhat sane again.

    When irqs are truely dynamically allocated?
