[PATCH 0/2] KVM: arm64: nv: A couple more VNCR fixes

[Oliver Upton <oupton@kernel.org>]

Another day, another handful of ugly MMU bugs.

The first addresses an issue where the host stage-1 VNCR mapping only
relies on the guest stage-1 permissions, potentially allowing RW
accesses to an RO PFN.

The second avoids a BUG_ON() in the case that the output of stage-1
translation exists outside of a memslot, and instead does the usual
thing and injects an SEA.

Based on kvmarm/next since the first pile of MMU changes was taken
(thanks!)

Oliver Upton (2):
  KVM: arm64: nv: Respect read-only PFN when mapping L1 VNCR
  KVM: arm64: nv: Inject SEA if kvm_translate_vncr() can't resolve PFN
