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.
