Merge branch irq/remove-handle-domain-irq-20211026 into irq/irqchip-next
* irq/remove-handle-domain-irq-20211026:
: Large rework of the architecture entry code from Mark Rutland.
: From the cover letter:
:
: <quote>
: The handle_domain_{irq,nmi}() functions were oringally intended as a
: convenience, but recent rework to entry code across the kernel tree has
: demonstrated that they cause more pain than they're worth and prevent
: architectures from being able to write robust entry code.
:
: This series reworks the irq code to remove them, handling the necessary
: entry work consistently in entry code (be it architectural or generic).
