commit efd48ceacea78e4d4656aa0a6bf4c5b92ed22130 upstream.
I suspect this is a -ECUTPASTE fault from the initial implementation. If
we don't declare the register ID to be KVM_REG_ARM64 the KVM_GET_ONE_REG
implementation kvm_arm_get_reg() returns -EINVAL and hilarity ensues.
The kvm/api.txt document describes all arm64 registers as starting with
0x60xx... (i.e KVM_REG_ARM64).
