Subject: [PATCH 0/4] sched/topology: fix overlap group capacity and balance cpu

This patchset is on top of Peter Zijlstra's sched/core tree[1]. It is equivalent
to the patch 3 from my previous patchset[2].

This patchset ensures:

 1) different instances of the same sched group share the same
    sched_group_capacity instance.
 2) instances of different groups don't share the same sched_group_capacity
    instance.
 3) the group balance cpu must be one of the cpus where the group is installed.

Lauro Ramos Venancio (4):
  sched/topology: optimize build_group_mask()
  sched/topology: all instances of a sched group must use the same
    sched_group_capacity
  sched/topology: move comment about asymmetric node setups
  sched/topology: the group balance cpu must be a cpu where the group is
    installed
