  17.      _kkkk_eeee_rrrr_nnnn______mmmm_aaaa_llll_llll_oooo_cccc allocates _n_u_m__b_y_t_e_s of kernel virtual memory. If necessary,
  18.      it sleeps until the entire requested memory is available. Therefore, do
  19.      not call this function from an interrupt routine. Memory is not
  20.      physically contiguous.

  29.      Drivers that use DMA should use _kkkk_mmmm_eeee_mmmm______aaaa_llll_llll_oooo_cccc(D3) to allocate buffers for
  30.      DMA and free that memory with _kkkk_mmmm_eeee_mmmm______ffff_rrrr_eeee_eeee(D3). For a discussion, see
