#     powerpc/pseries/mobility: Extend start/stop topology update scope
#     
#     The powerpc mobility code may receive RTAS requests to perform PRRN
#     (Platform Resource Reassignment Notification) topology changes at any
#     time, including during LPAR migration operations.
#     
#     In some configurations where the affinity of CPUs or memory is being
#     changed on that platform, the PRRN requests may apply or refer to
#     outdated information prior to the complete update of the device-tree.
#     
#     This patch changes the duration for which topology updates are
#     suppressed during LPAR migrations from just the rtas_ibm_suspend_me()
#     / 'ibm,suspend-me' call(s) to cover the entire migration_store()
#     operation to allow all changes to the device-tree to be applied prior
#     to accepting and applying any PRRN requests.
#     
#     For tracking purposes, pr_info notices are added to the functions
#     start_topology_update() and stop_topology_update() of 'numa.c'.
