a bit of pedantry -- in arch/ia64/xen/irq_xen.c:
/* Dummy stub. Though we may check XEN_RESCHEDULE_VECTOR before __do_IRQ,
* it ends up to issue several memory accesses upon percpu data and
* thus adds unnecessary traffic to other paths.
*/
__do_IRQ has been gone since 2011, so someone might want to update
that comment.
