Subject: [PATCH v2 0/9] KVM/ARM: Some vgic fixes and init sequence KVM selftests

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 ...

Best Regards

Eric

History:
- Took into account all comments from Marc and Alexandru's except
  the has_run_once still after the map_resources (this would oblige
  me to revisit in depth the selftests)
