    nvmm: Port to DragonFly #16: contiguous memory allocation
    
    svm_memalloc() and vmx_memalloc() need to allocate memory block that's
    both virtually contiguous and physically contiguous.  NetBSD achieves
    this requirement by first allocating a list of physically contiguous
    pages and a virtually contiguous memory address, and then mapping them
    page by page.
    
    We can just use contigmalloc(9) to achieve the same goal.
