Linus Torvalds cb69d86550 Updates for the interrupt subsystem:
- Core:
 	- Remove a global lock in the affinity setting code
 
 	  The lock protects a cpumask for intermediate results and the lock
 	  causes a bottleneck on simultaneous start of multiple virtual
 	  machines. Replace the lock and the static cpumask with a per CPU
 	  cpumask which is nicely serialized by raw spinlock held when
 	  executing this code.
 
 	- Provide support for giving a suffix to interrupt domain names.
 
 	  That's required to support devices with subfunctions so that the
 	  domain names are distinct even if they originate from the same
 	  device node.
 
 	- The usual set of cleanups and enhancements all over the place
 
   - Drivers:
 
 	- Support for longarch AVEC interrupt chip
 
 	- Refurbishment of the Armada driver so it can be extended for new
           variants.
 
 	- The usual set of cleanups and enhancements all over the place
