    Subject[PATCH 0/2] powerpc/nodes/hotplug: Fix problem with memoryless nodes
    Date
    powerpc/nodes: Ensure enough nodes avail for operations.
    On systems like PowerPC which allow 'hot-add' of CPU or memory
    resources, it may occur that the new resources are to be inserted
    into nodes that were not used for these resources at bootup. In
    the kernel, any node that is used must be defined and initialized
    at boot. This patch extracts the value of the lowest domain level
    (number of allocable resources) from the "rtas" device tree property
    "ibm,current-associativity-domains" or the device tree property
    "ibm,max-associativity-domains" to use as the maximum number of nodes
    to setup as possibly available in the system.

    powerpc/hotplug: Fix CPU-only node bringup bug
    On systems like PowerPC which allow 'hot-add' of CPU, it may occur
    that the new resources are to be inserted into nodes that were not
    used for memory resources at bootup. Many different configurations
    of PowerPC resources may need to be supported depending upon the
    environment. This patch fixes some problems encountered at runtime
    with configurations that support memory-less nodes, but which allow
    CPUs to be added at and after boot.
