Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

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"
