[PATCH 0/2] KVM: arm64: Avoid NULL dereference in vgic-v2 device attr accessors

[Oliver Upton <oliver.upton@xxxxxxxxx>]

Alex reports that it is possible to trigger a NULL dereference via the
vgic-v2 device attribute accessors, stemming from a lack of sanitization
of user input...

Here's a fix + regression test for the bug. Obviously, I intend to take
these as a fix ASAP.

  KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF
