[PATCH 15/15] arm64: KVM: Force undefined exception for Guest SMC intructions

[Marc Zyngier]

From: Anup Patel <anup.patel at linaro.org>

The SMC-based PSCI emulation for Guest is going to be very different
from the in-kernel HVC-based PSCI emulation hence for now just inject
undefined exception when Guest executes SMC instruction.
