 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
