This patch wasn't prompted by an actual problem I witnessed, but from
going through the list of W/As for SKL.
The need for that W/A was itself discovered through a preemption test,
there's no indication if it could occur with the non-preempted context
switch we do today.
I'd leave it out of fixes/stable then.
