    Pull irq updates from Thomas Gleixner:
     "Updates for the interrupt subsystem:
    
      Core changes:
    
       - Cleanup and simplification of common code to invoke the low level
         interrupt flow handlers when this invocation requires irqdomain
         resolution. Add the necessary core infrastructure.
    
       - Provide a proper interface for modular PMU drivers to set the
         interrupt affinity.
    
       - Add a request flag which allows to exclude interrupts from spurious
         interrupt detection. Useful especially for IPI handlers which
         always return IRQ_HANDLED which turns the spurious interrupt
         detection into a pointless waste of CPU cycles.
    
      Driver changes:
    
       - Bulk convert interrupt chip drivers to the new irqdomain low level
         flow handler invocation mechanism.
    
       - Add device tree bindings for the Renesas R-Car M3-W+ SoC
    
       - Enable modular build of the Qualcomm PDC driver
    
       - The usual small fixes and improvements"
