Is there a single IAPDESCR in your patch which contains only one of two flags IAP_F_SL and IAP_F_KL ? I mean that SDM lists desktop Skylake and Kabylake core events in the same table.

If IAP_F_KL just duplicates IAP_F_SL, the patch should be reduced to making Kabylake cpuids to fall to the skylake cputype.
