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
