I got a nice splat while testing out the toggling of
sched_asym_cpucapacity, so this is a cpuset fix plus a topology patch.

Details are in the logs.

v2 changes:
  - Use static_branch_{inc,dec} rather than enable/disable

v3 changes:
  - New patch: add fix for empty cpumap in sched domain rebuild
  - Move static_branch_dec outside of RCU read-side section (Quentin)

v4 changes:
  - Patch 1/2: Directly tweak the cpuset array (Dietmar)
  - Patch 2/2: Add an example to the changelog (Dietmar)


Valentin Schneider (2):
  sched/topology: Don't try to build empty sched domains
  sched/topology: Allow sched_asym_cpucapacity to be disabled
