At boot time for shared CPU lpars, the topology for each shared CPU is set to node zero, however, this is now updated correctly using the Virtual Processor Home Node (VPHN) capabilities information provided by the pHyp. The VPHN handling in Linux is disabled, if PRRN handling is present. powerpc/hotplug-memory: Removing or adding memory via the PowerPC hotplug interface shows anomalies in the association between memory and nodes. The code was updated to better take advantage of defined nodes in order to associate memory to nodes not needed at boot time, but relevant to dynamically added memory. Signed-off-by: Michael Bringmann <mwb@...ux.vnet.ibm.com> Michael Bringmann (2): powerpc/numa: Update CPU topology when VPHN enabled powerpc/hotplug-memory: Fix hot-add memory node assoc ---
