[GIT PULL] irqchip updates for 5.19

[Marc Zyngier]

Hi Thomas,

Here are the irqchip (and related) updates for 5.19. The most visible
change is the gpiolib rework to allow for immutable irq_chip
structures. Hopefully, people will take the hint and fix their drivers
so that we can get rid off the flag quickly enough (there is already a
large number of patches on the list on the subject).

The rest is a trickle of GICv3 changes and a bunch of minor fixes all
over the shop.

Please pull,

	M.

  Merge branch irq/gic-v3-nmi-fixes-5.19 into irq/irqchip-next (2022-05-17 10:37:06 +0100)

----------------------------------------------------------------
irqchip updates for 5.19:

- Add new infrastructure to stop gpiolib from rewriting irq_chip
  structures behind our back. Convert a few of them, but this will
  obviously be a long effort.

- A bunch of GICv3 improvements, such as using MMIO-based invalidations
  when possible, and reducing the amount of polling we perform when
  reconfiguring interrupts.

- Another set of GICv3 improvements for the Pseudo-NMI functionality,
  with a nice cleanup making it easy to reason about the various
  states we can be in when an NMI fires.

- The usual bunch of misc fixes and minor improvements.
