Pull irq updates from Thomas Gleixner:
"The irq departement provides the usual mixed bag:
Core:
- Further improvements to the irq timings code which aims to predict
the next interrupt for power state selection to achieve better
latency/power balance
- Add interrupt statistics to the core NMI handlers
- The usual small fixes and cleanups
Drivers:
- Support for Renesas RZ/A1, Annapurna Labs FIC, Meson-G12A SoC and
Amazon Gravition AMR/GIC interrupt controllers.
- Rework of the Renesas INTC controller driver
- ACPI support for Socionext SoCs
- Enhancements to the CSKY interrupt controller
- The usual small fixes and cleanups"
