Merge tag 'irq-core-2021-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq updates from Thomas Gleixner:
 "Updates to the interrupt core and driver subsystems:

  Core changes:

   - The usual set of small fixes and improvements all over the place,
     but nothing stands out

  MSI changes:

   - Further consolidation of the PCI/MSI interrupt chip code

   - Make MSI sysfs code independent of PCI/MSI and expose the MSI
     interrupts of platform devices in the same way as PCI exposes them.

  Driver changes:

   - Support for ARM GICv3 EPPI partitions

   - Treewide conversion to generic_handle_domain_irq() for all chained
     interrupt controllers

   - Conversion to bitmap_zalloc() throughout the irq chip drivers

   - The usual set of small fixes and improvements"
