    Andres, this patch moves some of the OF defines you added for OLPC from
    irq.c to prom.c which requires CONFIG_X86_OF to be enabled. A later
    patch changes irq_create_of_mapping() from returning intspec[0] to
    actually doing something. Could you please check how of OLPC gets broken
    and what we could do about it? :)

    Sebastian
