I'm seeing this on a POWER6 box:


CEDE_LATENCY: 			arch/powerpc/platforms/pseries/hotplug-cpu.c parse_cede_parameters Error calling get-system-parameter(0xfffffffd)


Seems overly verbose. Do we need to print success/fail on this call? Perhaps
a summary line if anything during initialisation failed:

Cede latency not supported

and

Cede latency supported

If it all worked.
