- * We need to hold call_lock, so there is no inconsistency

- * lock helps us to not include this cpu in a currently in progress
- * smp_call_function().

* We need to hold vector_lock so there the set of online cpus
* does not change while we are assigning vectors to cpus. Holding
* this lock ensures we don't half assign or remove an irq from a cpu.
