On some platforms the number of bits in the cbm_mask might not be

divisible by 4 (and not even by 2), so we need to properly count the

bits. Similar file, min_cbm_bits, is properly parsed and used, but if

the number is greater than one, we lose the information about

granularity when reporting the data in capabilities. For that matter

always report granularity, but if it is not the same as the minimum,

add that information in there as well.
