* kvm-arm64/pkvm-6.16:
  : .
  : pKVM memory management cleanups, courtesy of Quentin Perret.
  : From the cover letter:
  :
  : "This series moves the hypervisor's ownership state to the hyp_vmemmap,
  : as discussed in [1]. The two main benefits are:
  :
  :  1. much cheaper hyp state lookups, since we can avoid the hyp stage-1
  :     page-table walk;
  :
  :  2. de-correlates the hyp state from the presence of a mapping in the
  :     linear map range of the hypervisor; which enables a bunch of
  :     clean-ups in the existing code and will simplify the introduction of
  :     other features in the future (hyp tracing, ...)"
