[PATCH 0/6] pseries: Move CPU dlpar into the kernel

[Nathan Fontenot]

To better support CPU hotplug in PowerKVM and PowerVM environments, the
handling of CPU dlpar should be done entirely in the kernel. This will allow
a common entry point for PowerVM and PowerKVM CPU dlpar requests. For both
environments, the entry point is the same one introduced in a previous
patch set that moved memory hotplug into the kernel. The entry point accepts
a rtas hotplug event which is either constructed when using the 
/sys/kernel/dlpar interface or is passed to the kernel when handling a
ras epow interrupt.
