How to determine which kernel level corresponds to which service release for RHEL and SLES

Now and then I get the question – where to find the kernel level or version for a specific service release. And vice versa – I have kernel level x.y.z – what is the respective service level?
Both distributors SUSE as well as Red Hat offer this information on their web sites – even though not quite obvious to find. So here it is as a reference:

• Red Hat release table 
• SUSE release table including maintenance updates
