* 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)."
