KVM: PPC: HV: Remove generic instruction emulation
Now that we have properly split load/store instruction emulation and generic instruction emulation, we can move the generic one from kvm.ko to kvm-pr.ko on book3s_64. This reduces the attack surface and amount of code loaded on HV KVM kernels. Signed-off-by: Alexander Graf <agraf@suse.de>
