The usual boring updates from the interrupt subsystem:

Browse source 
- Infrastructure to allow building irqchip drivers as modules
 
  - Consolidation of irqchip ACPI probing
 
  - Removal of the EOI-preflow interrupt handler which was required for
    SPARC support and became obsolete after SPARC was converted to
    use sparse interrupts.
 
  - Cleanups, fixes and improvements all over the place
