irq-core-2021-06-29: Updates for the interrupt subsystem:
tagged this 29 Jun 13:37 
Core changes:

  - Cleanup and simplification of common code to invoke the low level
    interrupt flow handlers when this invocation requires irqdomain
    resolution. Add the necessary core infrastructure.

  - Provide a proper interface for modular PMU drivers to set the
    interrupt affinity.

  - Add a request flag which allows to exclude interrupts from spurious
    interrupt detection. Useful especially for IPI handlers which always
    return IRQ_HANDLED which turns the spurious interrupt detection into a
    pointless waste of CPU cycles.

Driver changes:

  - Bulk convert interrupt chip drivers to the new irqdomain low level flow
    handler invocation mechanism.

  - Add device tree bindings for the Renesas R-Car M3-W+ SoC

  - Enable modular build of the Qualcomm PDC driver

  - The usual small fixes and improvements.
