    Allocate kernel thread stacks out of kmem_map
    
    The kernel submaps eat most of the available kernel space. Using the
    main kernel map for thread stacks sometimes lead to exhaustion when many
    threads are created. Use kmem_map instead to increase this limit.
    
    * kern/thread.c (stack_alloc): Use kmem_map instead of kernel_map for
    stack allocation.
    (stack_collect): Likewise for release.
