    Yup cannot find equivalent bitmap operations for cpu_alloc.

    Also the search operations already use find_next_zero_bit() and
    find_next_bit(). So this should be okay.

    We could define new bitops:

    bitmap_set_range(dst, start, end)
    bitmap_clear_range(dst, start, end)

    int find_zero_bits(dst, start, end, nr_of_zero_bits)

    but then there are additional alignment requirements that such a generic
    function would not be able to check for.
