Just a heads-up, a couple of fixes to kvm-unit-tests were merged last week, and
among them was one touching the psci code, e14e6ba56f6e ("arm/arm64: psci: Don't
run C code without stack or vectors"). It might be worth checking that you have
it, and if you don't, if applying it fixes the issue.
Thanks,
