We're now ready to map our vectors in weird and wonderful locations. On enabling ARM64_HARDEN_EL2_VECTORS, a vector slot gets allocated if this hasn't been already done via ARM64_HARDEN_BRANCH_PREDICTOR and gets mapped outside of the normal RAM region, next to the idmap. That way, being able to obtain VBAR_EL2 doesn't reveal the mapping of the rest of the hypervisor code.
