Yeah, it's the TSX-Force-Abort acronym - Intel has numbed our general 
dislike to random acrynyms ...

Peter and me usually fix such changelog context omissions, but this one 
slipped through. :-/

The commit is too deep down perf/core already to rebase it just for the

I'll take care of it next time around.
