[PATCH 0/2] KVM: arm64: Fixes and clarifications for FEAT_S1POE

I (almost accidentally) spotted a couple of issues with the current NV
support for S1POE:

- wi->{e0,}poe and wr->{p,u}ov are used interchangeably, and sometimes
  in conjunction -- none of that makes much sense

- The two rules describing WXN are not exactly been applied to the
  correct state

These two patches address these issues (not that it matters much yet,
there is no S1POE HW out there).

  KVM: arm64: Remove the wi->{e0,}poe vs wr->{p,u}ov confusion
  KVM: arm64: Follow specification when implementing WXN
