Changes since v4:
1. Change sizeof(struct bin_attribute *) to sizeof(*hsmp_bin_attrs)
2. Change sizeof(struct attribute_group *) to sizeof(*hsmp_attr_grps)
3. Split some of the changes to 11th patch in this v5 series

Changes since v3:
New patch, based on Ilpos review comments and additional cosmetic changes.
