[v1,0/2] KVM: selftests: Fixes for broken tests

Message

During the course of implementing FEAT_LPA2 within the arm64 KVM port, I found a
couple of issues within the KVM selftest code, which I thought were worth
posting independently. The LPA2 patches, for which I will post v2 in the next
few days, depend on these fixes for its testing.

It turned out that there was another issue, for which I have posted a fix at
https://lore.kernel.org/kvmarm/[e-mail]/

With these 3 fixes, I see a clean run of the kvm selftests with the 64K kernel +
FEAT_LPA on FVP.

Thanks,
Ryan
