  KVM: x86/mmu: fix NULL pointer dereference on guest INVPCID (2022-05-20 13:49:52 -0400)

Sorry for the relatively large change so close to the release, but in
terms of lines added it's mostly selftests.

----------------------------------------------------------------
ARM:
* Correctly expose GICv3 support even if no irqchip is created
  so that userspace doesn't observe it changing pointlessly
  (fixing a regression with QEMU)

* Don't issue a hypercall to set the id-mapped vectors when
  protected mode is enabled (fix for pKVM in combination with
  CPUs affected by Spectre-v3a)

x86: Five oneliners, of which the most interesting two are:

* a NULL pointer dereference on INVPCID executed with
  paging disabled, but only if KVM is using shadow paging

* an incorrect bsearch comparison function which could truncate
  the result and apply PMU event filtering incorrectly.  This one
  comes with a selftests update too.

----------------------------------------------------------------
