If I may so humbly suggest: since ehea is a power6 thing only,
we should refocus our energie

To support ehea driver reloading in a kdump kernel the driver has to perform
firmware handle deregistrations when the original kernel crashes. As there's
currently no notifier chain for machine crashes this patch enables kdump support
in the ehea driver by bending the ppc_md.machine_crash_shutdown
