[PATCH v2 00/16] KVM: arm64: First batch of vgic-v5 related fixes

[Marc Zyngier]

This is the second revision of this series attempting to fix a number
of issues reported on the vgic-v5 PPI series.

* From v1 [1]:

  - Partially reverted the effective priority mask fix, as Sascha
    pointed out the crucial difference in the way GICv5 manages the
    PCR compared to GICv[234]'s PMR.

  - Added a fix for dealing with the pending HW-backed PPIs.

  - Added a workaround for the set_id_regs selftest, already posted
    separately, but included here for completeness (and ease of
    merging).

Patches on top of my kvm-arm64/vgic-v5-ppi branch.
