    kernel/kthread.c: partial revert of 81c98869 ("kthread: ensure locality of task_struct allocations")
    After discussions with Tejun, we don't want to spread the use of
    cpu_to_mem() (and thus knowledge of allocators/NUMA topology details) into
    callers, but would rather ensure the callees correctly handle memoryless
    nodes.  With the previous patches ("topology: add support for
    node_to_mem_node() to determine the fallback node" and "slub: fallback to
    node_to_mem_node() node if allocating on memoryless node") adding and
    using node_to_mem_node(), we can safely undo part of the change to the
    kthread logic from 81c98869.
