H A D | va_layout.c | dee39247 Thu Feb 15 05:47:14 CST 2018 Marc Zyngier <marc.zyngier@arm.com> arm64: KVM: Allow mapping of vectors outside of the RAM region
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.
