Pull x86 splitlock updates from Borislav Petkov:

 - Add Raptor Lake to the set of CPU models which support splitlock

 - Make life miserable for apps using split locks by slowing them down
   considerably while the rest of the system remains responsive. The
   hope is it will hurt more and people will really fix their misaligned
   locks apps. As a result, free a TIF bit.
