Merge tag 'irq-core-2022-08-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq updates from Thomas Gleixner:
 "Updates for interrupt core and drivers:

  Core:

   - Fix a few inconsistencies between UP and SMP vs interrupt
     affinities

   - Small updates and cleanups all over the place

  New drivers:

   - LoongArch interrupt controller

   - Renesas RZ/G2L interrupt controller

  Updates:

   - Hotpath optimization for SiFive PLIC

   - Workaround for broken PLIC edge triggered interrupts

   - Simall cleanups and improvements as usual"
