Merge tag 'irq-core-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq updates from Thomas Gleixner:
 "The usual boring updates from the interrupt subsystem:

   - Infrastructure to allow building irqchip drivers as modules

   - Consolidation of irqchip ACPI probing

   - Removal of the EOI-preflow interrupt handler which was required for
     SPARC support and became obsolete after SPARC was converted to use
     sparse interrupts.

   - Cleanups, fixes and improvements all over the place"
