Merge branch kvm-arm64/mmu/mapping-levels into kvmarm-master/next

Revamp the KVM/arm64 THP code by parsing the userspace
page tables instead of relying on an infrastructure that
is about to disappear (we are the last user).

* kvm-arm64/mmu/mapping-levels:
  KVM: Get rid of kvm_get_pfn()
  KVM: arm64: Use get_page() instead of kvm_get_pfn()
  KVM: Remove kvm_is_transparent_hugepage() and PageTransCompoundMap()
  KVM: arm64: Avoid mapping size adjustment on permission fault
  KVM: arm64: Walk userspace page tables to compute the THP mapping size
  KVM: arm64: Introduce helper to retrieve a PTE and its level
