Merge tag 'irqchip-5.16' into irq/core
Merge irqchip updates for Linux 5.16 from Marc Zyngier:
- A large cross-arch rework to move irq_enter()/irq_exit() into
the arch code, and removing it from the generic irq code.
Thanks to Mark Rutland for the huge effort!
- A few irqchip drivers are made modular (broadcom, meson), because
that's apparently a thing...
- A new driver for the Microchip External Interrupt Controller
- The irq_cpu_offline()/irq_cpu_online() API is now deprecated and
can only be selected on the Cavium Octeon platform. Once this
platform is removed, the API will be removed at the same time.
- A sprinkle of devm_* helper, as people seem to love that.
- The usual spattering of small fixes and minor improvements.
