z13 feature exploitation - which distribution levels are required

In this post I'll try to summarize which distribution levels, packages, APARs, PTFs etc are needed to exploit a given z13 (performance) function. I expect this to change over time, so please revisit for updates.

For the virtualization layers I use the label "(guest)" for enablement of guest exploitation. So you need at least the given version of the Hipervisor to exploit a certain function in the guest. Of course you also need the respective guest support.

All version levels in the table are minimum levels.
