Merge branch kvm-arm64/s1ptw-write-fault into kvmarm-master/fixes

* kvm-arm64/s1ptw-write-fault:
  : .
  : Fix S1PTW fault handling that was until then always taken
  : as a write. From the cover letter:
  :
  : `Recent developments on the EFI front have resulted in guests that
  : simply won't boot if the page tables are in a read-only memslot and
  : that you're a bit unlucky in the way S2 gets paged in... The core
  : issue is related to the fact that we treat a S1PTW as a write, which
  : is close enough to what needs to be done. Until to get to RO memslots.
  :
  : The first patch fixes this and is definitely a stable candidate. It
  : splits the faulting of page tables in two steps (RO translation fault,
  : followed by a writable permission fault -- should it even happen).
  : The second one documents the slightly odd behaviour of PTW writes to
  : RO memslot, which do not result in a KVM_MMIO exit. The last patch is
  : totally optional, only tangentially related, and randomly repainting
  : stuff (maybe that's contagious, who knows)."
