It's not clear how serious this FIXME is. Either it should be fixed (here or
later in the series), or explain why this isn't fixed yet. Presumably because
it is not a problem now, but it might be later when some other feature is
enabled.

How about:
for (i = 0; i < 32; i++)
ref_list[i] = i < b->num_valid ? b->index : 0x20;
Or:
memset(ref_list, b->index, b->num_valid);
memset(ref_list + b->num_valid, 0x20, 32 - b->num_valid);
Either approach is better IMHO than using two for-loops.
