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
