 - generic_handle_domain_irq() handles an interrupt described by a
   domain and a hwirq number
-- handle_domain_irq() does the same thing for root interrupt
-  controllers and deals with the set_irq_reg()/irq_enter() sequences
-  that most architecture requires
 
 Note that irq domain lookups must happen in contexts that are
 compatible with a RCU read-side critical section.
