3.16.49-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Zhihui Zhang <[email protected]> commit aaecac4ad46b35ad308245384d019633fb9bc21b upstream. The child variable in build_overlap_sched_groups() actually refers to the peer or sibling domain of the given CPU. Rename it to sibling to be consistent with the naming in build_group_mask().
