2016-02-26taskset: fix non-fancy cpuset printing on big-endianArnout Vandecappelle (Essensium/Mind)
The non-fancy version of the from_cpuset uses CPU_SETSIZE as if it represents the number of bytes in the cpuset, while it is actually the number of bits. This leads to out-of-bounds accesses on the cpu_set_t in the big-endian case. Basically all uses of CPU_SETSIZE have to be divided by 8. This is done correctly in the fancy version of from_cpuset. In addition, the big-endian case is completely wrong to begin with. All standard C libraries that I know of implement cpu_set_t as an unsigned long array, so both for big and little endian, the least significant bits are in the beginning of the array. Therefore, the approach taken for the little endian case is equally valid. We only need special handling for big endian when CPU_SETSIZE is large and we use an unsigned long long to get more bits out.
