Jesse Larrew 5d88aa85c0 powerpc/pseries: Update CPU maps when device tree is updated ... Platform events such as partition migration or the new PRRN firmware feature can cause the NUMA characteristics of a CPU to change, and these changes will be reflected in the device tree nodes for the affected CPUs. This patch registers a handler for Open Firmware device tree updates and reconfigures the CPU and node maps whenever the associativity changes. Currently, this is accomplished by marking the affected CPUs in the cpu_associativity_changes_mask and allowing arch_update_cpu_topology() to retrieve the new associativity information using hcall_vphn(). Protecting the NUMA cpu maps from concurrent access during an update operation will be addressed in a subsequent patch in this series.
