[PATCH 0/3] KVM: arm64: Address Translation fixes

[Marc Zyngier <maz@kernel.org>]

Here's a small series of fixes for KVM's implementation of address
translation (aka the AT S1* instructions), addressing a number of
issues in increasing levels of severity:

- We misreport PAR_EL1.PTW in a number of occasions, including state
  that is not possible as per the architecture definition

- We don't handle access faults at all, and that doesn't play very
  well with the rest of the VNCR stuff

- AT S1E{0,1} from EL2 with HCR_EL2.{E2H,TGE}={1,1} will absolutely
  take the host down, no questions asked

Patches based on 6.15-rc3.

Marc Zyngier (3):
  KVM: arm64: Fix PAR_EL1.{PTW,S} reporting on AT S1E*
  KVM: arm64: Teach address translation about access faults
  KVM: arm64: Don't feed uninitialised data to HCR_EL2
