powerpc/nodes: Ensure enough nodes avail for operations powerpc/initnodes: Ensure nodes initialized for hotplug hotplug/cpu: Fix crash with memoryless nodes Signed-off-by: Michael Bringmann <mwb@linux.vnet.ibm.com> Michael Bringmann (3): powerpc/nodes: Ensure enough nodes avail for operations powerpc/initnodes: Ensure nodes initialized for hotplug hotplug/cpu: Fix crash with memoryless nodes --- Changes in V7: -- Remove some node initialization/allocation from boot setup to later in runtime to try to limit memory needs early on -- Add some needed node initialization to runtime code that maps CPUs based on VPHN associativity -- Add error checks and alternate recovery for compile flag CONFIG_MEMORY_HOTPLUG -- Add alternate node selection recovery for !CONFIG_MEMORY_HOTPLUG -- Add initialization for systems that start using nodes before new CPU brought online. -- Make function find_cpu_nid() externally visible/usable so that it may be used from hotplug-cpu.c
