History
Michael Ellerman 8fc63a91e7 Merge branch 'smp-topo' into next 
Merge a branch containing SMP topology updates from Srikar, purely so we can
include the cover letter which has a lot of good detail here:

PowerVM systems configured in shared processors mode have some unique
challenges. Some device-tree properties will be missing on a shared
processor. Hence some sched domains may not make sense for shared processor
systems.

Most shared processor systems are over-provisioned. Underlying PowerVM
Hypervisor would schedule at a Big Core (SMT8) granularity. The most recent
power processors support two almost independent cores. In a lightly loaded
condition, it helps the overall system performance if we pack to lesser number
of Big Cores.

Since each thread-group is independent, running threads on both the
thread-groups of a SMT8 core, should have a minimal adverse impact in
non over provisioned scenarios. These changes in this patchset will not
affect in the over provisioned scenario.  If there are more threads than
SMT domains, then asym_packing will not kick-in.

Observation:
We are able to see Improvement in ebizzy throughput even with lesser
core utilization (almost half the core utilization) in low utilization
scenarios while still retaining throughput in mid and higher utilization
scenarios.
Note: The numbers are with Uncapped + no-noise case. In the Capped and/or
noise case, due to contention on the Cores, the numbers are expected to
further improve.

Note: The numbers included (sched/fair: Enable group_asym_packing in find_idlest_group)
