Some versions of gcc generate a warning that the variable "emulated" may be used uninitialized in function kvmppc_handle_load128_by2x64(). It would be used uninitialized if kvmppc_handle_load128_by2x64 was ever called with vcpu->arch.mmio_vmx_copy_nums == 0, but neither of the callers ever do that, so there is no actual bug. When gcc generates a warning, it causes the build to fail because arch/powerpc is compiled with -Werror. This silences the warning by initializing "emulated" to EMULATE_DONE.
