    Pull irq updates from Thomas Gleixner:
     "Updates for the interrupt subsystem:
    
      Treewide:
    
        - Cleanup of setup_irq() which is not longer required because the
          memory allocator is available early.
    
          Most cleanup changes come through the various maintainer trees, so
          the final removal of setup_irq() is postponed towards the end of
          the merge window.
    
      Core:
    
        - Protection against unsafe invocation of interrupt handlers and
          unsafe interrupt injection including a fixup of the offending
          PCI/AER error injection mechanism.
    
          Invoking interrupt handlers from arbitrary contexts, i.e. outside
          of an actual interrupt, can cause inconsistent state on the
          fragile x86 interrupt affinity changing hardware trainwreck.
    
      Drivers:
    
        - Second wave of support for the new ARM GICv4.1
    
        - Multi-instance support for Xilinx and PLIC interrupt controllers
    
        - CPU-Hotplug support for PLIC
    
        - The obligatory new driver for X1000 TCU
    
        - Enhancements, cleanups and fixes all over the place"
