Just IDVS group size. For some reason I thought there were more when I
wrote that commit message. It's split to avoid churn in that patch.

Logically, this series should contain three patches, with the IDVS group
size enablement patch at the end. That was the series I wrote and
committed to disk. For review I split it out, since the feature clean-up
can land now, while the (RFC) IDVS group size patch needs
testing/benchmarking.
