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.
