Pull irq updates from Thomas Gleixner:
 "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"
