Merge tag 'irq-core-2022-01-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq updates from Thomas Gleixner:
 "Updates for the interrupt subsystem:

  Core:

   - Provide a new interface for affinity hints to provide a separation
     between hint and actual affinity change which has become a hidden
     property of the current interface

   - Fix up the in tree usage of the affinity hint interfaces

  Drivers:

   - No new irqchip drivers!

   - Fix GICv3 redistributor table reservation with RT across kexec

   - Fix GICv4.1 redistributor view of the VPE table across kexec

   - Add support for extra interrupts on spear-shirq

   - Make obtaining some interrupts optional for the Renesas drivers

   - Various cleanups and bug fixes"
