KVM: arm64: nv: Snapshot S1 ASID tagging information during walk

Browse source

We currently completely ignore any sort of ASID tagging during a S1
walk, as AT doesn't care about it.

However, such information is required if we are going to create
anything that looks like a TLB from this walk.

Let's capture it both the nG and ASID information while walking
the page tables.
