While writting vgic v3 init sequence KVM selftests I noticed some relatively minor issues. This was also the opportunity to try to fix the issue laterly reported by Zenghui, related to the RDIST_TYPER last bit emulation. The final patch is a first batch of VGIC init sequence selftests. Of course they can be augmented with a lot more register access tests, but let's try to move forward incrementally ...
