powerpc/pseries: Partition migration in the kernel
Enable partition migration in the kernel. To do this a new sysfs file, /sys/kernel/mobility/migration, is created. In order to initiate a migration the stream id (generated by the HMC managing the system) is written to this file. After a migration occurs, and what is the majority of this code, the device tree needs to be updated for the new system the partition is running on. This is done via the ibm,update-nodes and ibm,update-properties rtas calls which return information regarding which nodes and properties of the device tree are to be added/removed/updated.
